on Sunday launched an anti-dumping investigation on polyformaldehyde copolymer imported from the European Union, the United States, China's Taiwan region and Japan.

The decision was made in accordance with the PRC's Anti-Dumping Provisions after reviewing materials provided by six Chinese companies that formally applied for the anti-dumping investigation last month as representatives of the relevant industry in mainland China.

The subject of the anti-dumping investigation will be polyformaldehyde copolymer, or POM copolymer for short, imported from the EU, the US, Taiwan region and Japan from January 1, 2023 to December 31, 2023.

It will also investigate whether there is any damage to China's POM copolymer industry from January 1, 2021 to December 31, 2023.

The ministry has called on interested parties to register with the ministry within 20 days to participate in the anti-dumping investigation starting Sunday.

The investigation is expected to conclude by May 19, 2025, but could be extended by six months under special circumstances.

POM copolymer is used in a wide range of industries, including auto parts, electronic devices, medical devices and construction materials.
