On May 18, 2025 China set a rate of 74.9% on imports of polyacetals from the US, 34.5% on imports from EU, and varying rates on imports from Japan and Taiwan. Imports from Japan were set a duty of 35.5%, except for Asahi Kasei, with a company-specific rate of 24.5%; imports from Taiwan were at 32.6%, except for Formosa Plastics, at 4%, and Polyplastics, at 3.8%.

China’s imports of polyacetals were very strong from September 2023 through December 2024 but fell off sharply as of January 2025, when the Commerce Ministry determined that dumping had occurred and implemented preliminary anti-dumping measures in effect from January 24, 2025. China’s imports through April 2025 were down 19%, to 114,000 tons.

Imports April 2025 YTD were lower from the US, several EU countries and also Taiwan. Imports from countries which were not implicated in the anti-dumping probe were also down, including South Korea and Malaysia.. New capacity in China likely contributed to the overall decline. In November, 2024, commercial operation was slated to begin at DP Engineering Plastics (Nantong), China. DP is owned by P. Holdings, Inc., in which Polyplastics holds a 70% stake and Global Polyacetal (Mitsubishi), 30%.
