China on Sunday announced antidumping duties as high as 74.9% on imports of POM copolymers, a type of engineering plastic, from the United States, the European Union, Japan and Taiwan.
The Chinese commerce ministry's findings conclude a probe launched in May 2024, shortly after the U.S. sharply increased tariffs on Chinese electric vehicles, computer chips and other imports.
POM copolymers can partially replace metals such as copper and zinc and have various applications including in auto parts, electronics and medical equipment, the ministry has said.
In January the ministry said initial investigations had determined that dumping was taking place, and implemented preliminary antidumping measures in the form of a deposit starting from Jan. 24.
According to Sunday's announcement, the highest antidumping rates of 74.9% were levied on imports from the U.S., while European shipments will face 34.5% duties.
China slapped 35.5% duties on Japanese imports, except for Asahi Kasei, which received a company-specific rate of 24.5%.
General duties of 32.6% were placed on imports from Taiwan, while Formosa Plastics received a 4% tariff and Polyplastics Taiwan 3.8%.
