The polyoxymethylene (POM) sector—an engineering plastic segment widely used in automotive, electronics, and medical applications—is entering a pivotal period shaped by international trade actions and supply chain realignments.
Recent policy decisions by China have significantly altered the global competitive environment for POM producers. The country launched an anti-dumping investigation in 2024 and later imposed tariffs on imports from major exporting regions including the European Union, United States, Japan, and Taiwan.
For stakeholders across manufacturing, chemical production, and supply chain management, these developments are not simply trade news. They signal structural changes that could influence sourcing strategies, pricing dynamics, and long-term investments.
Understanding Polyoxymethylene: Why This Engineering Plastic Matters
Polyoxymethylene, often referred to as POM copolymer, is a high-performance engineering plastic valued for its strength, durability, and dimensional stability.
It is frequently used as a substitute for metals such as copper and zinc in various industrial components.
Typical applications include:
- Automotive components
- Electronic and electrical appliances
- Industrial machinery parts
- Medical equipment
- Construction materials
Because of its mechanical strength and resistance to wear, POM enables manufacturers to produce lighter and more cost-efficient components while maintaining structural performance.
Polyoxymethylene Industry Disruption: China’s Anti-Dumping Investigation
In May 2024, the Ministry of Commerce of China initiated an anti-dumping investigation into imported POM copolymers from the European Union, United States, Japan, and Taiwan.
The probe examined imports during 2023 while evaluating damage to domestic manufacturers between 2021 and 2023.
Authorities concluded that dumping practices caused material injury to domestic producers, establishing a causal relationship between imported products and market damage.
The investigation initially allowed a timeline of about one year, with possible extension if necessary.
Tariffs That Changed the Competitive Landscape
Following the investigation, China introduced anti-dumping duties on imported POM copolymers in May 2025. These tariffs vary significantly depending on the origin of imports.
Anti-Dumping Duty Rates
| Origin Region | Duty Rate |
| United States | 74.90% |
| European Union | 34.50% |
| Japan | 35.5% (24.5% for Asahi Kasei) |
| Taiwan | 32.6% (3.8–4% for certain firms) |
The highest tariff—74.9%—targets imports from the United States, dramatically increasing the cost of supplying POM to the Chinese market.
These duties will apply for five years and require importers to pay the tariff at customs when bringing POM into China.
Strategic Implications for Global Supply Chains
The POM sector does not operate in isolation. It is closely linked to automotive manufacturing, electronics production, and industrial equipment supply chains.
Because of these connections, trade restrictions may trigger several ripple effects.
Potential impacts include:
- Supply Chain Realignment: Companies sourcing POM may diversify suppliers to reduce tariff exposure.
- Domestic Production Expansion: Chinese manufacturers may increase production to replace imports.
- Cost Adjustments: Industries relying on imported POM could experience higher raw material costs.
- Trade Policy Influence: The action highlights the use of anti-dumping tools under World Trade Organization frameworks to protect domestic industries.

From our strategic consulting perspective, the Polyoxymethylene Market is entering a phase where policy awareness becomes as critical as technological innovation.
Key Strategic Considerations
Trade Risk Management: Manufacturers should monitor trade regulations and tariff updates affecting engineering plastics.
Supply Diversification: Companies may evaluate alternative suppliers or regional production hubs to minimize exposure.
Long-Term Contracts: Securing multi-year procurement agreements could reduce volatility.
Domestic Capability Development: Countries facing high tariffs may expand local polymer production capacity.
Next Steps
Organizations involved in engineering plastics should consider the following actions:
- Monitor trade policy updates related to POM and other engineering plastics.
- Evaluate supplier diversification to reduce dependence on tariff-affected regions.
- Assess cost impacts across manufacturing operations.
- Develop supply chain resilience strategies for long-term stability.
- Track regional manufacturing investments that could alter future supply dynamics.
