On May 18, 2025, China’s Ministry of Commerce announced the conclusion of a year-long anti-dumping investigation into imports of polyoxymethylene (POM) polymers, resulting in the imposition of anti-dumping tariffs on imports from the United States, European Union, Japan, and Taiwan. The investigation was launched in May 2024 following the U.S. decision to raise tariffs on Chinese goods, including electric vehicles and semiconductor products reports the Baltimore Chronicle with reference to Reuters.
The investigation determined that dumping practices by the above-mentioned regions had caused material damage to Chinese manufacturers. As a result, China has implemented the following tariff rates:
- United States: 74.9%
- European Union: 34.5%
- Japan: 35.5% (with a 24.5% rate for Asahi Kasei Corp)
- Taiwan: 32.6% (4% for Formosa Plastics and 3.8% for Polyplastics Taiwan)
POM polymers are widely used in the automotive industry, electronics, and medical equipment as a metal substitute, replacing materials like copper and zinc.
These anti-dumping measures are part of China’s strategy to safeguard its domestic market and industry from unfair foreign competition.
