Europe's PVC Capacity Shrinks Again as US Chemical Giant Westlake Closes Cologne Plant

Westlake Corporation, the Houston-based US chemical group and a major global producer of polyvinyl chloride (PVC), announced on 29 September 2026 that it will permanently close its PVC plant in Cologne, Germany. The site, located in the Cologne-Merkenich chemical park and operated by its German subsidiary Westlake Vinnolit, can produce about 165,000 metric tons of PVC per year. Production is expected to stop during the first quarter of 2027.

Westlake explained that the Cologne plant is smaller and carries a heavier logistics burden than its other European PVC sites, which makes it more expensive to run. The decision comes as European chemical producers face weak demand, high energy costs and growing import pressure from Asia. Chief Executive Jean-Marc Gilson called the closure a difficult decision and said customers will continue to receive PVC from the group's other German plants.

The closure will cost Westlake about 205 million dollars in pre-tax charges, made up of roughly 100 million dollars in cash costs and 105 million dollars in non-cash charges. Around 110 million dollars will be booked in 2026 and the remainder in 2027. Reuters reported that about 120 jobs will be cut, while the chemical park's own site profile lists around 150 people working in PVC production there. As of 9 October 2026, no agreement with employee representatives on the terms of the job cuts has been made public, and the plant is scheduled to keep running until the shutdown early next year.

The move is a relocation of production within Germany rather than a withdrawal from the country. On 15 June 2026, Westlake Vinnolit completed the purchase of a PVC and vinyl chloride site in Wilhelmshaven, on the North Sea coast, which had been under insolvency administration after belonging to the Vynova group. That plant can produce 380,000 metric tons of PVC per year, more than twice the Cologne capacity, and has a deep-water dock that allows raw materials to arrive by ship. About 350 jobs were preserved there. Westlake also operates PVC sites in Burghausen, Gendorf and Hürth-Knapsack.

The Cologne plant had already shown its dependence on upstream supply earlier this year. On 13 May 2026, Westlake Vinnolit declared force majeure on PVC deliveries from both Cologne and nearby Hürth-Knapsack after a technical fault in the production of vinyl chloride, the main raw material for PVC, reportedly during a restart after maintenance. Market reports indicated that the force majeure was still in place in late June.

For buyers, the immediate effect on availability is limited because the European PVC market remains oversupplied. Prices fell through the summer after the spike that followed the Middle East conflict, and import offers have continued to undercut local material. The practical issue is continuity for customers currently served from Cologne, including makers of window profiles, pipes, flooring, cables, automotive parts and medical products. German trade press has advised processors to clarify now which plant will supply them from 2027, because a change of production site can require new material approvals and longer transport from the coast can raise freight costs. Buyers of specialty grades such as paste PVC are particularly concerned.

The Cologne closure adds to a long series of cuts in Europe's chlorine and vinyl chain. Vynova ended PVC production at its 225,000-ton plant in Beek, Netherlands, in November 2025. Dow approved in July 2025 the shutdown of its ethylene cracker in Böhlen and its chlor-alkali and vinyl assets in Schkopau by the fourth quarter of 2027, affecting around 550 jobs in Germany. Ineos announced in October 2025 the closure of two units in Rheinberg, including a chlorine plant, with 175 jobs lost. Westlake itself closed several chlorovinyl and styrene units in North America in December 2025. Germany's chemical association VCI reported in July 2026 that production fell about 3% in the first half of the year, cut its full-year forecast to a 1.5% decline and noted that investment is running about 15% below 2023 levels.

Trade policy is now the main variable for the market. On 23 September 2026, the European Commission opened an anti-dumping investigation into suspension PVC, the most common grade, imported from China, South Korea, Taiwan and Mexico, following a complaint by European producers. Imports from these four origins reached about 594,000 metric tons in the twelve months to March 2026. Provisional measures could be disclosed in April 2027 and definitive measures in November 2027. The United Kingdom opened a similar investigation in August 2026, and the EU has applied duties on PVC from the United States and Egypt since 2024. Market analysts have warned that if duties are imposed while local plants keep closing, European supply could tighten quickly.
