China’s Ministry of Commerce has imposed anti-dumping duties on POM copolymer imports from the US, EU, Japan, and Taiwan on 18 May 2025. Rates will range from 3.8% to 74.9%.
US imports will face the highest rate at 74.9%, while EU shipments are subject to 34.5%, and Japanese imports are set at 35.5%. However, Asahi Kasei Corp from Japan received a reduced rate of 24.5%. Taiwanese imports are assigned a rate of 32.6%, with Formosa Plastics and Polyplastics Taiwan benefiting from significantly lower tariffs at 4% and 3.8%, respectively.
Polyformaldehyde copolymer (POM copolymer) is used in automotive, electronics, machinery, sports gear, and medical devices. It’s a durable, efficient alternative to metals like copper, zinc, tin, and lead, easily replacing traditional materials.
The commerce ministry said it imposed these new anti-dumping duties after an investigation in May 2024, shortly after the US increased tariffs on Chinese electric vehicles, computer chips, and other imports.
Earlier, the White House released a joint statement on 12 May 2025 announcing that the US will lower the “de minimis” tariff on low-value shipments from China to 30%.
On 11 May 2024, the US and China agreed to a trade deal that would pause for 90 days most retaliatory tariffs imposed since April.
The EU had imposed various anti-dumping duties on Chinese imports. On 29 April 2025, the European Commission announced that it had imposed duties of up to 66.7% on imports of Chinese construction lifts.
Prior to that, the EU had implemented anti-dumping and anti-subsidy duties on nearly 80 Chinese products, ranging from biodiesel imports to ironing boards to bicycles, to address unfair trade practices.
