Dow Inc. is an American multinational chemical corporation headquartered in Midland, Michigan. It is the publicly traded holding company, incorporated in Delaware, for The Dow Chemical Company, its principal operating subsidiary. Dow has been among the three largest chemical producers in the world, operates in approximately 160 countries and employs about 36,000 people. It has often been described as the chemical companies' chemical company, because the great majority of what it makes is sold to other manufacturers rather than to consumers.

The company was founded in 1897 by the chemist Herbert Henry Dow, who had devised a method of extracting bromine from the underground brine deposits beneath Midland. From that narrow beginning it diversified within twenty years into chlorine, agricultural chemicals, dyestuffs, phenol and magnesium, and from the 1930s into the plastics that became its largest business. It was a strategically important producer during both world wars, supplying magnesium for aircraft, styrene for synthetic rubber and materials the United States had previously imported from Germany.

Dow's modern corporate history was reshaped by the transaction agreed with DuPont in December 2015, under which the two companies merged in 2017 to form DowDuPont and then separated in 2019 into three independent businesses covering agriculture, materials science and specialty products. Dow Inc. is the materials science company that emerged from that separation and took the Dow Chemical name with it.

The company's record has been the subject of sustained controversy. It managed the Rocky Flats nuclear weapons plant during a period of repeated contamination, was the sole remaining manufacturer of napalm B for the Vietnam War after other suppliers withdrew, produced Agent Orange, inherited responsibility for Union Carbide and by extension the public campaign over the Bhopal disaster after acquiring that company in 2001, and has been found liable in cases concerning dioxin contamination of Michigan rivers, price fixing in polyurethane, and abusive tax structures.

History

Herbert Dow and the founding, 1897 to 1930

Herbert Henry Dow graduated from the Case School of Applied Science in Cleveland, where his thesis concerned the chemical composition of brines. Beneath Midland, Michigan, lay the remains of a prehistoric sea in the form of salt brine rich in bromine, and Dow devised an electrolytic method of extracting it that was substantially cheaper than the prevailing process. He founded the Dow Chemical Company in 1897 after two earlier ventures had failed.

The company at first sold only bleach and potassium bromide, reaching bleach output of 72 tons a day by 1902. Its survival in the early years depended on two episodes of price warfare that became part of the company's founding mythology. A group of British manufacturers attempted to drive Dow from the bleach market by cutting prices; Dow cut its own, lost about US$90,000 of income and began diversifying rather than depending on a single product. In 1905 a German bromide cartel began dumping bromides cheaply in the United States to prevent Dow from selling in Europe. Rather than compete on price at home, Dow bought the cheap German product in America and shipped it back to Europe, undercutting the cartel in its own market with its own goods.

Within twenty years the company was a substantial producer of agricultural chemicals, elemental chlorine, phenol, dyestuffs and magnesium metal. Charles J. Strosacker, another Case graduate, joined in 1907 and became a central figure in the company's management for decades.

The First World War transformed Dow's position. The United States had imported a large share of its chemicals from Germany, and the blockade created immediate shortages. Dow supplied magnesium for incendiary flares, monochlorobenzene and phenol for explosives and bromine for medicines and tear gas, and by 1918 some 90 per cent of its production served the war effort. The diamond logo the company still uses dates from this period.

After the war the company continued to develop magnesium, producing Dowmetal pistons that were lighter than cast iron and gave greater speed and fuel efficiency. They were adopted in racing, and the winner of the 1921 Indianapolis 500 used them.

Herbert Dow died on 15 October 1930 of cirrhosis of the liver while under treatment at the Mayo Clinic. He held more than ninety patents personally and had been awarded the Perkin Medal in January of that year.

Willard Dow and the Second World War, 1930 to 1949

Willard Dow, born in 1897, the year his father founded the company, had been required to work in every department at Midland. He became a director in 1922 and general manager of the Midland plant in 1926, and succeeded to the leadership at the age of 33 when his father died. Strosacker joined the board.

The company invested heavily in research through the Great Depression, a decision that shaped the following half century. In the 1930s it began producing plastic resins, which became its largest business: ethylcellulose in 1935 and polystyrene in 1937.

Magnesium

Between 1940 and 1941, in eight months, Dow built a plant at Freeport, Texas, to extract magnesium from seawater rather than from underground brine. The Freeport site became the company's largest and the largest integrated chemical manufacturing complex in the United States, adding power generation, chlorine, caustic soda and ethylene production. When Japan attacked Pearl Harbor in December 1941 it was the primary American source of magnesium.

At the government's request Dow doubled Freeport capacity, built a second plant at Velasco, Texas, and added plants on the shores of Lake Michigan and Lake Huron. In 1942, the year in which air supremacy over Europe was contested, Dow-operated plants produced 84 per cent of American magnesium output. Magnesium was essential to lightweight aircraft components, and the business made Dow a strategic company for the duration of the war.

Styrene and synthetic rubber

The Japanese conquest of Southeast Asia cut off natural rubber supplies almost entirely. The synthetic substitute selected by the federal government was styrene-butadiene rubber, and Dow was the only American producer of styrene. In 1942 it agreed to assist the government's synthetic rubber programme and operated several plants at federal request. Its first foreign expansion, Dow Chemical of Canada at Sarnia, Ontario, was established to produce styrene for the same purpose.

Plastics and Dow Corning

Dow supplied several plastics to the military, including Ethocel, foamed polystyrene marketed as Styrofoam, and Saran, later sold to consumers as Saran Wrap. In 1943 Corning Glass Works and Dow formed Dow Corning to develop silicone products for military use; its first product, Dow Corning 4 Compound, sealed aircraft ignition systems so that they could operate at high altitude. After the war Dow Corning turned to civilian products and became the largest producer of silicones in the world.

The war reached the company's own installations. The Ethyl-Dow plant at Kure Beach, North Carolina, the only East Coast facility extracting bromine from seawater, was shelled by a German submarine in 1942.

Willard Dow died in an aircraft crash on 31 March 1949. Leland Doan became president, Earl Bennett became chairman, Mark Putnam was named general manager, Calvin Campbell secretary and Carl Gerstacker treasurer. Gerstacker, who had returned from army service as a major in 1946 and moved from production engineering into finance, joined the board in 1948 and became one of the most influential figures in the company's postwar development.

Leland Doan and the consumer turn, 1949 to 1962

Leland Doan became president in 1949 and set about reorganising the company for a peacetime economy. Wartime production gave way to a residential construction boom, and by 1960 almost two thirds of American households owned their homes. Dow had always sold to other companies, but Doan recognised the opportunity in consumer demand and built a catalogue of household products, beginning with Saran Wrap in 1953.

He decentralised authority to department heads, expanded the sales force and trained it to analyse markets and production processes rather than simply to take orders. A US$25 million programme for expansion into plastics was announced, with new facilities planned from 1951 under a US$100 million budget. Foreign expansion resumed with the first overseas subsidiary in Japan in 1952 and others soon afterwards.

Gerstacker became vice-president in 1955, joined the executive committee the following year and was appointed chairman in 1960. Doan reached the company's mandatory retirement age in 1962. Over his thirteen years employment had more than doubled from 14,000 to 31,000 and sales had risen from US$200 million to US$890 million.

Ted Doan and the troika, 1962 to 1971

Ted Doan, Leland's son, became president at 40. He integrated the company's separate branches into a single organisation oriented toward growth outside the United States and set a target of increasing earnings by 10 per cent a year. Sales passed US$1 billion in 1964 and US$2 billion by 1971.

Doan introduced an open-door policy for employees, increased the emphasis on research and visited the laboratories regularly. He formed a management arrangement known internally as the troika, after the Russian three-horse team, with Gerstacker responsible for finance and marketing, Ben Branch for international business and manufacturing, and Doan for everything else. The three met on alternate Monday mornings and once a year withdrew for a week to set strategy and assess all 300 senior managers, making personnel changes on their return.

Overseas manufacturing was found to create demand rather than merely serve it, and Dow built plastics plants in Germany, Greece, Spain and Italy. The largest investment was the complex at Terneuzen in the Netherlands, opened in 1965 and still among the company's principal sites. Plants followed in Argentina, Colombia and New Zealand. In 1965 the management concluded that the company had become too large to run centrally and established regional headquarters, creating Dow Europe, Dow Latin America and Dow Pacific in 1966, together with technology centres for 33 key products.

Doan stepped down in 1971 at 48. He and Gerstacker established a rule that presidents, chief executives and chairmen must leave their posts at 60 and retire at 65, with the intervening five years known within the company as deceleration. He remained on the boards of Dow and Dow Corning until 1987. Ben Branch became president and chief executive in 1971.

The 1990s reorganisation and the consumer disposal

In the early 1990s Dow restructured from a geographic hierarchy, in which regional presidents reported to the chief executive, into global business units, so that the head of a product line was responsible for its plants everywhere. The change reflected a general movement in multinational manufacturing away from country management toward global product management, and it made comparisons of performance across regions possible in a way the previous structure had obscured.

In October 1997 S. C. Johnson and Son agreed to buy DowBrands, the consumer products division based in Indianapolis, completing the purchase on 23 January 1998 for US$1.1 billion. The sale transferred Ziploc, Saran and Handi-Wrap in home food management and Fantastik, Scrubbing Bubbles and Spray'n Wash in home care. It marked a deliberate decision to concentrate on specialty and industrial materials rather than compete for supermarket shelf space against companies whose expertise lay in marketing rather than chemistry.

Union Carbide, 1999 to 2001

In August 1999 Dow agreed to buy Union Carbide for US$9.3 billion in stock, creating what was then the second largest chemical company in the world behind DuPont. The purchase was completed in 2001. Some shareholders objected that Dow had not adequately disclosed potential liabilities arising from the Bhopal disaster, the 1984 gas release at a plant operated by Union Carbide's Indian subsidiary.

The acquisition has shaped the company's public reputation ever since. Dow's position has been that Union Carbide settled its liability with the government of India in 1989 for US$470 million, that the Bhopal site passed to the state of Madhya Pradesh, and that Dow never operated the plant. Campaigners have argued that a corporation that buys a company acquires its obligations along with its assets, and the annual anniversary of the disaster has produced protests directed at Dow rather than at a company that no longer exists independently.

William S. Stavropoulos served as president and chief executive from 1995 to 2000 and again from 2002 to 2004, having been a director since 1990 and chairman from 2000, relinquishing his board seat in April 2006. He led the Union Carbide purchase, which was subsequently blamed for the poor results under his successor Mike Parker; Parker was dismissed and Stavropoulos returned from retirement.

Restructuring and the financial crisis, 2006 to 2010

On 31 August 2006 Dow announced closures at five locations. The most significant was Sarnia, Ontario, its first Canadian manufacturing site, established in 1942 at the Canadian government's invitation to produce styrene for synthetic rubber, with a polystyrene plant added in 1947. In August 1985 the site accidentally discharged 11,000 litres of perchloroethylene into the St. Clair River, an incident the press named the Blob, for which Dow Canada was charged by the provincial environment ministry. Employment there fell from about 1,600 in the early 1990s to roughly 400 by 2002 as units closed, the chlor-alkali business closing in 1994. Dow Canada moved its headquarters to Calgary in 1996. The whole site ceased operations at the end of 2008 after BP advised that the western Canadian ethylene pipeline supply should be suspended on safety grounds, leaving the remaining plants uncompetitive. The low-density polyethylene and polystyrene units closed in 2006, latex in 2008 and propylene oxide derivatives in April 2009, and the remediated site was sold to TransAlta and renamed the Bluewater Energy Park. Other closures affected a styrene polymer unit at Barry in South Wales, a plant at Porto Marghera near Venice, and two plants at Fort Saskatchewan in Alberta.

In April 2007 Dow dismissed two senior executives, the executive vice-president Romeo Kreinberg and the director and former chief financial officer J. Pedro Reinhard, for unauthorised discussions with third parties about a possible sale of the company. Dow said they had been in secret contact with JPMorgan Chase at a time when the Sunday Express reported a possible leveraged buyout. Both sued, claiming they had been dismissed as a threat to the chief executive Andrew Liveris and that the allegations were a pretext. In June 2008 the parties settled, with both men dropping their claims and acknowledging that they had taken part in discussions about a potential buyout that were neither authorised by nor disclosed to the board, and that it would have been appropriate to inform the chief executive and directors.

In December 2007 Dow announced a series of moves intended to reduce the cyclicality of the business, including an exit from automotive sealers and, within weeks, a joint venture with Petrochemical Industries Company, a subsidiary of Kuwait Petroleum Corporation, later called K-Dow. In exchange for US$9.5 billion Dow would sell half its interest in five global businesses covering polyethylene, polypropylene and polycarbonate plastics and ethyleneamines and ethanolamines. The proceeds were intended to fund a move up the value chain.

On 10 July 2008 Dow agreed to buy Rohm and Haas for US$15.4 billion, or US$78 a share, financed in part by equity investments of US$3 billion from Berkshire Hathaway and US$1 billion from the Kuwait Investment Authority. The object was to move decisively into specialty chemicals, which earn higher margins and are harder for competitors to enter than commodities. Many analysts considered the price excessive, representing a premium of about 75 per cent to the previous day's market value, though a high bid had been necessary to deter BASF.

The financial crisis then removed the funding. On 28 December 2008 the Kuwaiti government terminated the K-Dow agreement, citing the global recession, destroying the cash that was to have paid for Rohm and Haas and dealing a serious blow to Liveris's restructuring strategy. Dow announced on 6 January 2009 that it was in discussions with other possible partners and would pursue damages from the Kuwaiti company, and it later recovered about US$2.2 billion in arbitration.

On 8 December 2008 Dow accelerated its cost reductions, announcing the closure of 20 facilities, the temporary idling of 180 plants and the elimination of 5,000 full-time jobs, about 11 per cent of the workforce, together with 6,000 contractor positions. On 26 January 2009 it informed Rohm and Haas that it could not complete the purchase by the agreed deadline, citing the credit markets and the K-Dow collapse. On 12 February 2009 the board cut the quarterly dividend from US$0.42 to US$0.15, the first reduction in the 97-year history of the payment and a decision Liveris had previously said was not off the table. After negotiating the sale of preferred stock to Rohm and Haas's two largest shareholders and extending a bridge loan, Dow completed the purchase on 1 April 2009 at the agreed price of about US$15 billion.

Portfolio reshaping, 2013 to 2017

From 2013 Dow began developing several plants on the American Gulf Coast as part of a transition away from naphtha as a feedstock and toward ethane derived from shale gas. Cheap American natural gas liquids had transformed the economics of petrochemical production, giving producers on the Gulf Coast a cost advantage over European and Asian competitors dependent on oil-derived naphtha, and prompted the largest wave of chemical investment in the United States in decades. Dow estimated that the facilities would employ about 3,000 people permanently and 5,000 during construction, producing materials for hygiene and medical applications, transportation, electrical and telecommunications, packaging, consumer durables and sports and leisure. A propane dehydrogenation unit at Freeport with capacity of 750,000 tonnes a year was expected in 2015 and an ethylene facility in the first half of 2017.

On 27 March 2015 Dow and Olin Corporation agreed that Dow would separate a substantial part of its chlorine business and merge it with Olin, creating a business with revenue approaching US$7 billion and making Olin the largest chlorine producer in the world. Chlorine had been among Dow's founding products; its disposal was a clear statement that scale in commodity chemistry no longer justified the capital it consumed.

In December 2015 Dow sold part of its global herbicide business to the privately held Gowan Company of Yuma, Arizona, after nearly a year of falling sales. The portfolio comprised dinitroaniline weed killers, including the trademarks for Treflan, Edge, Team, Bonalan and Sonalan and the intellectual property for products based on trifluralin, benfluralin and ethalfluralin, together with a formulation and packaging facility at Fort Saskatchewan. It had earlier sold its zoxamide fungicide business, including the Gavel potato and grape fungicide, to the same company in 2008.

By 2015 the company had adopted an explicit policy of shedding commodity businesses such as those producing the raw materials for grocery bags and plastic pipe, whose margins were low, and concentrating resources on specialty chemicals earning at least 20 per cent.

DowDuPont and the three-way separation, 2015 to 2019

On 11 December 2015 Dow announced an all-stock merger with DuPont. The combined company, DowDuPont, was valued at approximately US$130 billion, was held equally by the shareholders of both companies and retained headquarters in Michigan and Delaware. It was to be divided within two years into three independent public companies covering agriculture, materials science and specialty products. Andrew Liveris became executive chairman and DuPont's Edward Breen chief executive. The merger closed in 2017 after regulatory delays, with conditions including divestitures required by the European Commission.

On the same day in December 2015 Dow agreed to acquire Corning's stake in the Dow Corning joint venture for US$4.8 billion in cash and roughly a 40 per cent interest in Hemlock Semiconductor Corporation, bringing the silicones business fully into Dow after 72 years as a joint venture.

The structure was unusual. Two of the largest chemical companies in the world merged in order to separate immediately afterwards along different lines from those on which they had been organised, so that each successor would have a coherent portfolio rather than the historical accumulation each parent carried. Activist investors, including Third Point and Trian, had pressed both companies toward breaking up, and the merger was in substance a means of rearranging assets before doing so.

The separation completed on 1 April 2019, when Dow Inc. became an independent public company and the direct parent of The Dow Chemical Company, taking the materials science businesses. Corteva took the agricultural businesses and a reconstituted DuPont took specialty products. Dow Corning became Dow Silicones Corporation, a wholly owned subsidiary trading as Dowsil.

Recent history, 2019 to 2026

Jim Fitterling, who had joined the company in 1984, became chief executive of the separated Dow. The early years were shaped by the COVID-19 pandemic, during which demand for packaging and hygiene materials rose while automotive and construction markets contracted sharply, and by the company's decision to convert capacity at several sites to produce hand sanitiser, supplying it without charge to hospitals and government agencies.

The subsequent period has been difficult for the European chemical industry in particular. The loss of cheap Russian natural gas after the invasion of Ukraine in 2022 raised energy and feedstock costs for European producers to levels at which many assets became structurally uncompetitive against American and Middle Eastern plants. Dow announced reviews of its European asset base, and in 2025 confirmed closures of several upstream European plants including a cracker in Germany and siloxanes capacity in the United Kingdom, together with cost reductions and a reduction of the dividend, the first since 2009. A major new net-zero emissions cracker project at Fort Saskatchewan, Alberta, announced as Path2Zero, was delayed as the company preserved cash.

In April 2026 Dow announced that Karen S. Carter, a long-serving executive who had held human resources and commercial leadership roles, would become chief executive on 1 July 2026, with Jim Fitterling moving to executive chairman. Carter became one of very few Black women to lead a Fortune 500 company.

The Oreffice and Popoff years, 1978 to 1995

Paul Oreffice, an Italian-born executive who had joined Dow in Brazil and run its Spanish and Latin American operations, became president in 1978 and chief executive from 1979, serving as chairman until 1992. Frank Popoff succeeded him as chief executive in 1987 and as chairman in 1992, serving until 1995. Between them they ran the company for nearly two decades, a period in which its identity as a commodity chemical producer came under pressure from three directions.

The first was cyclicality. Dow's earnings swung violently with the price of oil and the state of the world economy, collapsing in the recession of the early 1980s and again in the early 1990s, and the management concluded that a business whose profits disappeared entirely at the bottom of each cycle could not sustain the research spending on which its future depended. The response was to move toward specialty products with more stable margins, a strategy pursued with varying determination by every subsequent chief executive and never fully achieved.

The second was litigation. The breast implant claims against Dow Corning, the Agent Orange settlements, and a large volume of claims concerning workplace exposure and product liability occupied management attention and consumed capital throughout the period. Oreffice in particular became known for a combative public posture, arguing that the company was being blamed for the consequences of decisions taken by governments and that the scientific basis for many claims was absent.

The third was the environmental movement's transformation of public expectations. Dow was among the founding participants in Responsible Care, the chemical industry's voluntary programme of safety, health and environmental management launched in Canada in 1985 and adopted in the United States in 1988, under which member companies committed to continuous improvement and to community engagement. Critics regarded it as self-regulation intended to forestall legislation; the industry argued that it produced measurable reductions in emissions and incidents. Dow's own emissions of listed toxic chemicals fell substantially across the 1990s, in common with the industry as a whole, though from a very high base.

Popoff oversaw the structural reorganisation into global business units and began the process of disposing of businesses that did not fit, which culminated in the DowBrands sale shortly after his departure.

Agricultural chemicals

Dow entered agricultural chemistry early, and by the 1930s was a significant producer of insecticides and fumigants. The business was consolidated as Dow Elanco in 1989, a joint venture with Eli Lilly's agricultural division, which Dow bought outright in 1997 and renamed Dow AgroSciences. It produced herbicides, insecticides and fungicides alongside a seeds and traits business, and its products included the organophosphate insecticide chlorpyrifos, sold as Lorsban and Dursban.

Chlorpyrifos became the most contested product in the portfolio. Residential uses were withdrawn in the United States in 2000 after evidence of harm to children, and epidemiological studies subsequently associated prenatal exposure with reduced cognitive development. The Environmental Protection Agency proposed a full ban on food uses in 2015, reversed that position in 2017, and was ordered by a federal appeals court to act, finally revoking food tolerances in 2021; the European Union withdrew approval in 2020. The agricultural business passed to Corteva in the 2019 separation, and with it the remaining liabilities.

The separation of agriculture from materials science was among the clearest logical outcomes of the DowDuPont transaction. The two businesses shared little beyond chemistry: agriculture depends on regulatory approvals, seed genetics, field trials and farmer relationships, and operates on cycles measured in growing seasons, while materials science depends on plant construction, feedstock costs and industrial customers. Holding both inside one company had obscured the performance of each.

Products and operating segments

Dow reports through three operating segments.

Packaging and Specialty Plastics

The largest segment produces ethylene and propylene and their derivatives, principally polyethylene, together with the hydrocarbons business that supplies the feedstocks. Dow is among the largest polyethylene producers in the world, supplying material for food packaging, films, pipes, caps and closures, wire and cable insulation, and moulded goods. Product lines include the Dowlex linear low-density polyethylene family, Elite enhanced polyethylene resins and the Infuse and Intune olefin block copolymers used in footwear, adhesives and compatibilisers. Innovation in the segment has concentrated on recyclability, including resins designed so that a package can be made from a single material family and therefore separated and reprocessed, and on incorporating post-consumer recycled and bio-based content.

Industrial Intermediates and Infrastructure

This segment supplies polyurethanes and their raw materials, propylene oxide and propylene glycol, industrial solvents, surfactants, amines, cellulosics and construction chemicals. Its markets include building insulation, furniture and bedding, appliances, coatings, adhesives, agricultural formulations, pharmaceuticals and energy. The water solutions business supplies Filmtec reverse osmosis membranes and ion exchange resins used in desalination, industrial water treatment and ultrapure water for semiconductor manufacturing, a business whose growth is tied to water scarcity and to the expansion of chip fabrication.

Performance Materials and Coatings

This segment comprises the silicones business, trading as Dowsil and derived from the former Dow Corning, together with coatings materials including acrylic binders, dispersants and cellulosic additives. Silicones are used in construction sealants, personal care products, electronics, transportation and healthcare, and the coatings business supplies the resins and additives from which architectural and industrial paints are formulated.

Historic and divested products

Dow's consumer products, including Saran Wrap, Ziploc bags and Scrubbing Bubbles, were sold to S. C. Johnson in 1997. Styrofoam, the extruded polystyrene foam board used in construction insulation, remains one of the most widely recognised trademarks the company ever created, and is frequently misapplied by the public to the expanded polystyrene used in disposable cups and packaging, which Dow did not make. The agricultural chemicals business, including the pesticide chlorpyrifos sold as Lorsban, passed to Corteva in the 2019 separation; chlorpyrifos has since been banned for food uses in the United States and the European Union following findings about neurodevelopmental effects in children.

Finances

Dow Inc. reported revenue of approximately US$43 billion in 2024. Its earnings are strongly cyclical, because commodity chemical margins depend on the spread between feedstock costs and product prices, both of which move with energy markets and with the global industrial cycle. The industry has also been subject to long capacity cycles in which periods of high margins prompt investment that arrives together several years later and depresses prices, a pattern visible in the Chinese capacity additions of the 2020s that coincided with weak demand and compressed margins worldwide.

The company has traditionally been valued by investors for its dividend, which it maintained without reduction from 1912 until 2009 and again from 2009 until the reduction announced in 2025. Its capital allocation has been contested between shareholders seeking returns and the very large sums required for new crackers and decarbonisation projects, each of which costs billions of dollars and takes most of a decade to build.

Chemistry and manufacturing

Dow's business rests on a small number of chemical conversions carried out at enormous scale, and the structure of the company follows the structure of those value chains.

Steam cracking

The foundation of the largest segment is the steam cracker, a furnace in which a hydrocarbon feedstock is mixed with steam and heated to above 800 degrees Celsius for a fraction of a second, breaking large molecules into smaller unsaturated ones, principally ethylene and propylene, together with butadiene, benzene and hydrogen. The products are separated by fractional distillation at cryogenic temperatures and fed into downstream plants that polymerise them or react them further.

The choice of feedstock determines both cost and product mix. Naphtha, a refinery stream derived from crude oil, yields a broad slate including substantial quantities of propylene, butadiene and aromatics. Ethane, obtained from natural gas liquids, yields almost entirely ethylene and is far cheaper where gas is abundant. The shale gas expansion in the United States after 2008 made American ethane among the cheapest petrochemical feedstocks in the world and prompted Dow's Gulf Coast investment programme, while leaving European crackers running on naphtha at a structural disadvantage that widened further when Russian gas supplies ended in 2022. The consequence for Dow's product mix was a shortage of propylene, addressed by building propane dehydrogenation capacity at Freeport that converts propane directly into propylene.

Crackers are among the largest and most capital-intensive units in industry, costing several billion dollars, taking five or more years to build and running continuously for years between planned shutdowns. Their scale and the difficulty of storing their products mean that a cracker must be built adjacent to the plants that consume its output, which is why chemical production concentrates in integrated complexes such as Freeport, Terneuzen and Jubail rather than being distributed.

Polymerisation

Polyethylene, Dow's largest product, is made by linking ethylene molecules into chains, and its properties depend on how the chains branch and pack together. High-density polyethylene has few branches, packs tightly and is rigid, suiting bottles and pipes. Low-density polyethylene, made at very high pressure, has long branches and is soft and clear, suiting films and bags. Linear low-density polyethylene, in which short branches are introduced by copolymerising ethylene with a longer olefin, combines toughness with flexibility and is the basis of Dow's Dowlex family.

The catalysts used determine the precision with which these structures can be controlled. Dow was among the developers of constrained geometry single-site catalysts, which produce polymers of much more uniform molecular architecture than the earlier Ziegler-Natta systems, enabling the Elite and Infuse product families and permitting films to be made thinner without loss of strength. Reducing the material required for a given package is both a cost advantage and the company's principal answer on plastic waste.

Chlorine and the chlor-alkali chain

Dow's founding chemistry was electrolytic. Passing current through brine produces chlorine, caustic soda and hydrogen, and for most of the twentieth century this chain underpinned the company's production of solvents, vinyl chloride, epoxy resins, propylene oxide and a very large part of industrial chemistry generally, since chlorine appears as an intermediate in the manufacture of many products that contain none of it in the end. The process is extremely energy intensive, which ties its economics to electricity prices, and the co-production of chlorine and caustic soda in fixed proportion creates a persistent commercial problem, since demand for the two rarely moves together. Dow's exit from most of the chain into the Olin transaction in 2015 ended more than a century of chlor-alkali production.

Silicones

Silicone chemistry, developed at Dow Corning from 1943, begins with silicon metal reacted with methyl chloride to form chlorosilanes, which are hydrolysed and polymerised into siloxane chains. The resulting materials are stable across a far wider temperature range than organic polymers, resist ultraviolet light and weathering, and can be made as fluids, gels, elastomers or resins. They are consequently used where organic materials fail: in construction sealants exposed to decades of weather, in engine and transmission components, in medical devices, in personal care products and in the encapsulation of electronic components.

Research and development

Dow has maintained a large central research organisation at Midland since the founder's own laboratory, and its continued investment through the Great Depression and subsequent downturns has been a consistent feature of its management culture. Its researchers have been associated with the development of commercial magnesium extraction from seawater, extruded polystyrene foam board, saran polymers, single-site polyolefin catalysts, reverse osmosis membranes for desalination and a large body of silicone chemistry.

The company has held tens of thousands of patents and has generally pursued a strategy of protecting process technology as trade secret where possible and product technology by patent, since a competitor can often deduce a product's composition but not the conditions under which it was economically made.

Its research agenda since the separation has concentrated on three areas: polymer designs that permit mechanical recycling, including packaging structures made entirely from one material family; chemical recycling processes that return mixed waste plastic to feedstock; and decarbonisation of the cracking step, through electrification, hydrogen firing and carbon capture. Each is technically feasible at laboratory scale and each faces the same obstacle, which is that the incumbent process is extremely cheap and the alternatives are not.

Operations and sites

Dow operates manufacturing at more than a hundred sites in around thirty countries. Its largest is Freeport, Texas, an integrated complex covering several thousand acres with crackers, chlorine, glycol, polyethylene and specialty plants, and the largest integrated chemical manufacturing site in the United States. Terneuzen in the Netherlands is its largest European site and among the largest in Europe, supplied by sea and by pipeline connections to the Antwerp and Rotterdam industrial cluster. Other major locations include Midland, which houses the headquarters, research laboratories and silicones production; Plaquemine and St. Charles in Louisiana; Seadrift and Texas City in Texas; Stade and Böhlen in Germany; Tarragona in Spain; Bahía Blanca in Argentina; Map Ta Phut in Thailand; Zhangjiagang in China; and, through the Sadara joint venture, Jubail in Saudi Arabia.

The geography of the industry reflects the cost of moving its inputs. Ethylene cannot economically be shipped long distances, so it is made where feedstock is cheap and converted immediately into polymers that can be transported as pellets. This is why chemical investment has concentrated successively in the American Gulf Coast, the Middle East and China, and why the European industry, which has neither cheap feedstock nor cheap energy, has been contracting.

Safety

Process safety is the central operational discipline of a chemical company, since the materials handled are flammable, toxic or both and are held at high temperature and pressure in very large quantities. Dow developed the Fire and Explosion Index, a quantitative method of ranking process hazards first published in 1964 and revised repeatedly since, which became a standard tool across the industry for identifying where protective measures should be concentrated. Its safety statistics for employee injury rates have generally been among the better in the sector.

The record is not unblemished. Explosions and releases have occurred at Dow and Union Carbide sites over the decades, and the acquisition of Union Carbide brought with it the legacy of the worst industrial accident in history. The company has also been criticised over the cumulative exposure of communities living beside its plants, particularly in Louisiana and Texas, where petrochemical corridors carry elevated pollution burdens borne disproportionately by low-income and predominantly Black communities, a pattern that has become the central case in the American environmental justice literature.

Competition and industry structure

Dow's principal competitors are BASF, the largest chemical company in the world by revenue; LyondellBasell and ExxonMobil Chemical in polyolefins; Shell, TotalEnergies and Ineos in European petrochemicals; SABIC and Borouge in the Middle East; Sinopec and a large number of Chinese state and private producers; and specialised competitors in each downstream area, including Wacker and Shin-Etsu in silicones and Toray and Suez in membranes.

The industry's structure has changed substantially since 2015. Capacity additions in China, driven by a policy of substituting domestic production for imports, have eliminated the export markets on which Western producers relied and have created global oversupply in several major products. Middle Eastern producers with access to ethane at administered prices operate at costs no import-dependent producer can match. The consequence has been a prolonged margin downturn from 2023 and a wave of closures in Europe, with most large Western producers reviewing or reducing their European asset bases.

Regulation has become a more significant competitive factor. The European Union's chemicals strategy for sustainability, restrictions on per- and polyfluoroalkyl substances, carbon border adjustment arrangements and extended producer responsibility rules for packaging all impose costs that vary by jurisdiction, and the industry has argued that divergent rules displace production rather than reduce emissions. Critics respond that the industry has made the same argument against every environmental measure for fifty years.

Corporate culture and Midland

Midland, a town of about 42,000 people in central Michigan, exists in its present form because of Dow. The company built the laboratories, funded the hospital, the library, the centre for the arts and the botanical gardens, and its architects, particularly Alden B. Dow, gave the town an unusual concentration of modernist buildings. The Dow Gardens and the Alden B. Dow Home and Studio are open to visitors, and the Herbert H. and Grace A. Dow Foundation, endowed by the founder's family and separate from the company, has been among the largest philanthropic funders in Michigan.

The relationship has the characteristics of a company town, including the concentration of economic and civic influence in one institution and the difficulty of separating the interests of the town from those of the employer, a tension that became visible during the dioxin contamination dispute, when residents pressing for remediation were also employees or the relatives of employees.

Internally the company has been characterised by long tenures, promotion from within and a culture of technical seriousness, with several chief executives having spent their entire working lives there. The founding family remained involved through three generations, and the rule established by Ted Doan and Carl Gerstacker requiring senior executives to leave their posts at 60 institutionalised succession in a way few companies have matched.

Employees and labour relations

Dow employs about 36,000 people, a number that has fallen steadily through successive restructurings from a peak above 60,000 before the disposals of the 1990s and 2000s. Its American operations have historically included both represented and unrepresented sites, with unions including the United Steelworkers representing operators at several large plants, and European operations are covered by works councils and national bargaining arrangements.

The company has been a consistent early adopter of workplace practices later taken up more widely, including formal safety programmes, employee resource groups and, from the 1990s, benefits extended to the partners of employees in same-sex relationships. It has also been criticised for the human cost of its restructurings, particularly the closures announced in 2006 and 2008 which eliminated thousands of positions in towns where Dow was the principal employer and where no comparable work existed.

Compensation for senior executives has been contested at several points, most prominently during the financial crisis when the dividend was cut for the first time in 97 years while executive pay was maintained, and again during the 2025 European closures.

Digital operations and supply chain

Dow formed a Business Process Service Center in 2006 to consolidate transactional functions, and has since pursued a programme of digital investment that is characteristic of heavy industry: sensors and predictive analytics to anticipate equipment failure before it causes an unplanned shutdown, which in a continuous process plant costs millions of dollars a day; optimisation of the cracker feed slate against changing feedstock prices; and digital ordering and inventory tools for customers.

Logistics is a larger part of the business than its public profile suggests. Dow moves very large volumes by pipeline, rail, barge and ship, operates one of the largest private rail fleets in North America, and is among the largest shippers of hazardous materials in the world. The safety of rail transport of chemicals became a subject of public attention after the derailment at East Palestine, Ohio, in 2023 involving vinyl chloride, a material Dow no longer produces but whose transport conditions are set by rules the industry collectively shapes.

The company's supply chain was severely disrupted by the winter storm that struck Texas in February 2021, which forced the shutdown of most Gulf Coast petrochemical production for weeks and produced shortages of plastics and chemicals that propagated through manufacturing worldwide for the remainder of the year, an episode that demonstrated how far global manufacturing depends on a geographically concentrated set of chemical plants.

Controversies

Rocky Flats and nuclear weapons, 1951 to 1975

From 1951 to 1975 Dow managed the Rocky Flats Plant near Denver, Colorado, a facility of the Atomic Energy Commission that manufactured the plutonium triggers for thermonuclear weapons. Contamination from fires and from the leakage of radioactive waste recurred throughout the period. A 1957 fire burned plutonium dust and released radioactive particles into the atmosphere, and a further major fire occurred in 1969; drums of plutonium-contaminated oil stored outdoors leaked into the soil, from which wind carried contamination toward populated areas.

The Department of Energy transferred management to Rockwell International in 1975. In 1990 residents of the surrounding area brought a class action against Dow and Rockwell over contamination of their land, which after nearly three decades of litigation was settled in 2017 for US$375 million. The appellate court had held that the owners of the 12,000 properties in the class area had not established that their properties were damaged or that they had suffered bodily injury, and the settlement resolved the matter without a finding on those questions.

Napalm and Agent Orange

Dow was one of several manufacturers that began producing napalm B under government contract from 1965 for use in the Vietnam War. Napalm B, a mixture of polystyrene, benzene and gasoline, adhered to surfaces and burned at temperatures that made it lethal well beyond the point of impact, and photographs of its effects on civilians became among the defining images of the war.

As protests and adverse publicity mounted, the other suppliers withdrew, leaving Dow as the sole producer. The company said that it had considered its position carefully and had decided as a matter of principle that its first obligation was to the government. Anti-war groups boycotted its products and its recruiters were confronted on university campuses, in what became one of the most sustained campaigns of corporate protest of the era and an early instance of activists targeting a supplier rather than the government itself. Dow continued to manufacture napalm B until 1969, when it lost the contract.

Dow also produced Agent Orange, a defoliant containing the contaminant 2,3,7,8-tetrachlorodibenzo-p-dioxin, at Terneuzen in the Netherlands, New Plymouth in New Zealand and Midland, Michigan, for British forces during the Malayan Emergency and American forces in Vietnam. Approximately twenty million gallons were sprayed over Vietnam, Laos and Cambodia. American veterans exposed to it reached a US$180 million settlement with the manufacturers in 1984. A suit brought in 2005 by Vietnamese victims against Dow and Monsanto was dismissed on the ground that the herbicide was not a poison banned by international law at the time and that the manufacturers, as government contractors, were not liable. In 2012 Monsanto settled a case brought by former employees and residents of Nitro, West Virginia, where a 1949 explosion had damaged a tank containing 2,4,5-T, for US$93 million, of which US$9 million was for cleaning affected homes and US$84 million for medical monitoring and treatment.

Bhopal

The Bhopal disaster occurred in December 1984 at a pesticide plant owned by Union Carbide India Limited, a subsidiary of Union Carbide. A cloud of methyl isocyanate and other chemicals spread into neighbourhoods where more than half a million people lived. The government of Madhya Pradesh confirmed 3,787 deaths attributable to the release, with 558,125 injuries recorded, including 38,478 temporary partial injuries and approximately 3,900 cases of severe and permanent disability; independent estimates of the eventual death toll are considerably higher.

Union Carbide was sued by the government of India and agreed an out-of-court settlement of US$470 million in 1989. Dow acquired Union Carbide in 2001. Campaigners have sought to hold Dow responsible for remediation of the site, which is controlled by the state of Madhya Pradesh and where contamination of soil and groundwater has persisted, and for further compensation to survivors and to those affected by contamination since the release. Dow's position is that the settlement resolved all claims, that it never owned or operated the plant, and that responsibility for the site passed to the state government.

Dow Corning and silicone breast implants

Dow Corning, the joint venture with Corning, was a major manufacturer of silicone breast implants and was sued extensively from the early 1990s by women who attributed connective tissue disease and other systemic illness to ruptured implants. The volume of litigation drove the company into Chapter 11 bankruptcy protection in 1995, from which it emerged in 2004 after establishing a settlement fund of around US$2.35 billion. Cases pending against Dow Chemical itself in the district court were dismissed on 6 October 2005.

Subsequent large independent reviews of the scientific literature, including by the Institute of Medicine in the United States, found no evidence that silicone breast implants cause breast cancer or any identifiable systemic disease. The episode is frequently cited in discussions of mass tort litigation as a case in which a company was driven into bankruptcy by claims that the scientific evidence did not ultimately support, and equally as a case in which manufacturers had failed to conduct adequate safety studies before marketing an implanted device.

DBCP

Until the late 1970s Dow produced 1,2-dibromo-3-chloropropane, a soil fumigant and nematicide sold as Nemagon and Fumazone. Plantation workers in Central America who alleged sterility and other harm sued Dow and Dole Foods in Latin American courts. The litigation was extensively corrupted: test results were falsified and plaintiffs were recruited who had never worked on Dole plantations. Nicaraguan courts awarded more than US$600 million, which the claimants have been unable to collect. A group then sued in the United States and was awarded US$3.2 million by a Los Angeles jury on 5 November 2007. Dole and Dow appealed, and on 23 April 2009 a Los Angeles judge dismissed both cases on grounds of fraud and extortion by Nicaraguan lawyers recruiting fraudulent claimants, a ruling that cast doubt on some US$2 billion of judgments in comparable suits.

Dioxin in the Tittabawassee River

Areas along the Tittabawassee River in Michigan, which passes within yards of Dow's Midland plant, were found in November 2006 to contain elevated concentrations of dioxin. The contamination lay in sediments two to ten feet below the riverbed, and The New York Times reported that there was no indication of direct exposure for residents or workers, although people who frequently ate fish from the river showed slightly elevated blood levels.

In July 2007 Dow agreed with the Environmental Protection Agency to remove 50,000 cubic yards of sediment from three contaminated areas of the riverbed and levees. In November 2008 Dow, the EPA and the Michigan Department of Environmental Quality agreed to establish a Superfund arrangement to address dioxin in the Tittabawassee and Saginaw rivers and Saginaw Bay, a remediation that has continued for more than fifteen years and is among the largest river cleanups in the United States. Dow also funded studies of dioxin exposure in the local population and reached settlements with the state over natural resource damages.

Tax shelters

In February 2013 a federal court rejected two tax shelter transactions that had generated approximately US$1 billion in deductions for Dow between 1993 and 2003, writing that they were schemes designed to exploit perceived weaknesses in the tax code and not for legitimate business reasons. The structures had been created by Goldman Sachs and the law firm King and Spalding and involved a partnership operated from Dow's European headquarters in Switzerland. Dow, which had paid the assessments with interest and was suing for a refund, appealed to the Fifth Circuit, which again rejected its claims, and then petitioned unsuccessfully for a rehearing before the full court.

Polyurethane price fixing

Dow was implicated in a conspiracy to fix the price of polyurethane chemicals. The Department of Justice closed its criminal investigation in 2007 without charges, but a class action proceeded and the plaintiffs won at trial in 2013. After the Supreme Court declined to hear an appeal, Dow settled in 2016 for US$835 million, one of the largest antitrust settlements in the chemical industry.

Environmental record

Dow's environmental position is contested in a way characteristic of the chemical industry. The company is among the largest industrial consumers of energy and water in the world and a significant emitter of greenhouse gases, principally from the steam crackers that convert hydrocarbons into ethylene and propylene at temperatures above 800 degrees Celsius. It is simultaneously a supplier of materials that reduce emissions elsewhere, including building insulation, lightweight automotive components, wind turbine blade resins and membranes for water purification, and the company's own accounting emphasises this avoided emissions effect.

It has committed to reducing net annual carbon emissions by five million tonnes from a 2020 baseline by 2030 and to carbon neutrality by 2050, and the Path2Zero project at Fort Saskatchewan was designed as the world's first net-zero emissions ethylene cracker, using hydrogen produced from its own off-gas with carbon capture and storage. The project's delay in 2025 illustrated the difficulty of financing decarbonisation in a cyclical industry during a downturn.

On plastic waste, Dow has committed to enabling the collection and recycling of large volumes of plastic and to producing significant quantities of circular and renewable products by 2030, and has invested in chemical recycling ventures that break plastic back into feedstocks. Environmental organisations have argued that the company's production volumes far exceed what any recycling system can absorb, that chemical recycling remains unproven at scale and energy intensive, and that the industry has historically promoted recycling in order to forestall restrictions on production, a criticism supported by internal industry documents from the 1980s and 1990s disclosed in later investigations.

Leadership

Presidents and chief executives of Dow have included Herbert Henry Dow from 1897 to 1930; Willard Dow from 1930 to 1949; Leland Doan from 1949 to 1962; Ted Doan from 1962 to 1971; Ben Branch from 1971; Paul Oreffice; Frank Popoff; William Stavropoulos from 1995 to 2000 and again from 2002 to 2004; Michael Parker from 2000 to 2002; Andrew Liveris from 2004 to 2018; Jim Fitterling from 2018; and Karen S. Carter from July 2026. Carl Gerstacker, chairman from 1960 to 1976, was among the most influential figures in the company's history and was known for his remark that he had long dreamed of buying an island owned by no nation on which to locate the company's world headquarters, a statement frequently quoted in discussions of corporate statelessness.

Sponsorships and collaborations

Dow was a worldwide partner of the International Olympic Committee as the official carbon partner of the Olympic Games from 2010, supplying materials for venues and funding emissions mitigation projects. It has sponsored the Dow Great Lakes Bay Invitational on the women's golf tour, held near its Midland headquarters, and has long supported the Midland Center for the Arts and other institutions in its home city, where it is by a wide margin the dominant employer and civic presence.

Its collaborations have included a Lab Safety Academy providing free chemistry safety training resources to schools and universities, and a long-running partnership with The Nature Conservancy begun in 2011 to develop methods of valuing ecosystem services in business decisions, work that produced tools subsequently adopted by other companies.

Part-owned companies and notable people

Dow has held substantial interests in joint ventures including Hemlock Semiconductor Corporation, a producer of polysilicon for the semiconductor and solar industries; Sadara Chemical Company, a very large integrated complex at Jubail in Saudi Arabia developed with Saudi Aramco; Kuwait joint ventures including EQUATE and MEGlobal; and Dow Corning until its full acquisition in 2016.

Among the company's notable figures are Herbert Dow, who received more than ninety patents and the Perkin Medal; his son Alden B. Dow, an architect who studied under Frank Lloyd Wright and designed many buildings in Midland; Carl Gerstacker; and Andrew Liveris, who after leaving Dow chaired the organising committee for the Brisbane Olympic Games.

Public perception and legacy

Few industrial companies have occupied so contested a place in public life. Dow was, during the Vietnam War, the most visible corporate target of the American protest movement, to the point that campus recruitment visits became occasions for demonstrations and arrests, and the company's decision to continue producing napalm when its competitors would not has followed it for sixty years. Its acquisition of Union Carbide attached to it the memory of Bhopal, and its Michigan operations produced one of the longest-running dioxin remediation disputes in the country.

Against this stands a record of technical achievement and of products that are genuinely difficult to do without. Building insulation reduces energy consumption; reverse osmosis membranes supply drinking water to hundreds of millions of people in places where fresh water is scarce; packaging materials prevent food spoilage on a scale that outweighs their waste burden by most measures of resource use; and the lightweight materials in vehicles and wind turbines reduce emissions across their service lives. The company's own framing emphasises this contribution, and its critics reply that the question is not whether chemistry is useful but whether the costs of producing it have been fairly distributed and honestly disclosed.

Both readings capture something. Dow has repeatedly been in the position of a supplier whose products are indispensable and whose consequences are borne by people who did not choose them, and the pattern of its history since 1950 is largely the record of how that tension has been managed, litigated and, occasionally, resolved.
