Overview

  • China has imposed anti-dumping duties on POM copolymer imports from the US, EU, Japan, and Taiwan, with rates as high as 74.9% for US shipments.
  • The duties follow a year-long investigation launched in May 2024 after the US increased tariffs on Chinese electric vehicles and chips.
  • POM copolymers, used in auto parts, electronics, and medical equipment, are strategically significant as substitutes for metals like copper and zinc.
  • Specific duties include 34.5% on EU imports, 35.5% on Japanese imports (24.5% for Asahi Kasei Corp), and 32.6% on Taiwanese imports (4% for Formosa Plastics and 3.8% for Polyplastics Taiwan).
  • The announcement underscores persistent trade friction, even as APEC warns of systemic risks to global trade and a temporary US-China tariff truce is in place.
