China Imposes Anti-Dumping Duties on Polyoxymethylene Imports from US, EU, Taiwan, and Japan

China’s Commerce Ministry has set anti-dumping tax rates on polyoxymethylene (POM) imports originating from the United States, the European Union, Taiwan, and Japan, effective as of the announcement date. The decision follows a year-long investigation that found evidence of dumping and material injury to the domestic POM industry.

Investigation Findings and Preliminary Rulings

The probe, initiated in May 2024, examined POM resin imports from the four regions. Preliminary findings, released in October 2024, indicated dumping margins ranging from 7% to 42% depending on the producer. The final ruling, published by the Ministry of Commerce, confirms these margins and sets definitive anti-dumping duties for a period of five years. The rates vary by company and region, with some producers receiving individual rates based on their cooperation during the investigation.

Affected Producers and Regional Breakdown

Under the final determination, companies in the United States face duties between 7.2% and 32.6%, while EU producers are subject to rates from 9.8% to 42.0%. Taiwanese manufacturers received rates ranging from 8.4% to 33.5%, and Japanese companies from 6.8% to 27.9%. These rates are applied to the CIF (cost, insurance, freight) value of the imported goods. The Ministry noted that cooperating companies received lower rates, while non-cooperating entities faced the highest applicable duties.

Impact on Domestic and International Markets

Polyoxymethylene, also known as acetal resin, is a high-performance engineering plastic used in automotive parts, electronics, and consumer goods. The anti-dumping duties are expected to raise import prices, potentially benefiting domestic Chinese producers such as Yuntianhua and Baotailong. However, downstream manufacturers may face higher raw material costs, which could be passed on to consumers. Internationally, the ruling adds to existing trade tensions, particularly with the US and EU, and may prompt retaliatory measures or disputes at the World Trade Organization.

Conclusion

China’s imposition of anti-dumping duties on POM imports from the US, EU, Taiwan, and Japan marks a significant trade action with implications for global chemical markets. The five-year duties aim to protect domestic industry but also risk raising costs for Chinese manufacturers and escalating trade frictions. As the ruling takes effect, stakeholders will monitor its impact on supply chains and pricing.

FAQs

Q1: What is polyoxymethylene and why is it important?
Polyoxymethylene (POM) is a high-strength engineering plastic used in precision parts for automotive, electronics, and industrial applications. It is valued for its durability, low friction, and dimensional stability.

Q2: How long will the anti-dumping duties be in effect?
The duties are set for a period of five years from the date of the final ruling, subject to possible review or renewal.

Q3: How do these duties affect consumers?
Consumers may see higher prices for products containing POM, such as car parts, electronic components, and household appliances, as import costs increase and may be passed down the supply chain.
