China imposed tariffs of up to 75% of anti-dumping duties on plastic imports from the United States, the European Union, Taiwan, and Japan on Monday after an investigation into suspected dumping, according to the country’s commerce ministry.
The newly imposed tariffs apply to imports of polyformaldehyde copolymer, a widely used plastic found in automotive components, medical equipment, and household appliances.

The decision follows a Chinese investigation initiated in May 2024, shortly after the U.S. increased tariffs on Chinese electric vehicles, computer chips, and other imports. It comes just days after Washington and Beijing reached a 90-day truce to reduce punitive tariffs on each other.

On Sunday, the ministry stated that imports from the United States were subjected to the highest anti-dumping tariff of 74.9%, while shipments from Europe will incur 34.5% duties. According to the ministry, POM copolymers serve as a substitute for metals like copper and zinc, with versatile applications across electronics and automotive parts.

Beijing has often initiated anti-dumping investigations against nations involved in broader trade conflicts. In January, the ministry declared that initial investigations had confirmed instances of dumping and introduced preliminary anti-dumping measures, requiring a deposit beginning January 24.

China levied a 35.5% tariff on Japanese imports, except for Asahi Kasei Corporation, which received a company-specific rate of 24.5%. A general duty of 32.6% was applied to imports from Taiwan, while Formosa Plastics faced a 4% tariff and Polyplastics Taiwan 3.8%.
In April, China implemented anti-dumping tariffs on European Union brandy, which affected France’s export-dependent cognac industry.
