China has imposed anti-dumping duties on imports of POM copolymers from the United States, the European Union, Japan, and Taiwan, with rates as high as 74.9%. The decision follows an investigation initiated in May 2024, shortly after the U.S. increased tariffs on Chinese goods, including electric vehicles and computer chips.

POM copolymers, which can substitute metals like copper and zinc, are used in auto parts, electronics, and medical equipment. Preliminary anti-dumping measures, in the form of a deposit, were implemented starting January 24, based on initial findings of dumping.

The highest anti-dumping rate of 74.9% has been levied on imports from the United States, while European shipments face duties of 34.5%. Japanese imports will incur duties of 35.5%, except for Asahi Kasei Corp, which will have a company-specific rate of 24.5%. Imports from Taiwan face general duties of 32.6%, with Formosa Plastics receiving a 4% tariff and Polyplastics Taiwan 3.8%.

Despite these trade measures, there are hopes that the U.S.-China trade war may be easing. Both countries have reportedly agreed to slash reciprocal tariffs in a 90-day truce. The Asia-Pacific Economic Cooperation group of nations recently cautioned about "fundamental challenges" confronting the global trading system.
