EU Opens Anti-Dumping Probe into Chinese PA6 Imports

The European Commission launched an anti-dumping investigation on November 6 into imports of polyamide-6 (PA6) originating in China. The probe follows a complaint submitted by Envalior Deutschland GmbH, Nurel SA and UBE Corporation Europe on behalf of the EU industry.

Filed on September 23, 2026, the complaint claims that Chinese PA6 imports are entering the EU market at dumped prices, harming local producers through rising import volumes, downward pressure on prices and declining market share. It also alleges that state intervention has created significant distortions in China's production costs. In addition, the complainants argue that an export duty on benzene, an upstream raw material used in PA6 production, has distorted raw material prices.

The Commission determined that the evidence presented was sufficient to initiate an investigation under EU anti-dumping regulations. The product covered is PA6 polymer containing at least 95% PA6 by weight, currently listed under CN code ex 3908 10 00 and TARIC code 3908 10 00 10.

The investigation will assess alleged dumping and injury over the period from July 1, 2025, to June 30, 2026. The examination of injury trends will cover the longer period between January 1, 2023, and June 30, 2026.

The Commission also plans to ask customs authorities to register imports of PA6 from China at an early stage of the investigation. A separate regulation will be issued for this purpose. Such registration could make it possible to collect definitive anti-dumping duties retroactively on the registered imports, provided the relevant legal requirements are met and the investigation's outcome supports the measure.

PA6 resins are widely used in manufacturing automotive components, consumer products and industrial goods.

In the related PA66 segment, the Commission imposed definitive anti-dumping duties of 29.1-42.3% on adipic acid imports from China in May 2026, after introducing provisional measures in November 2025. Adipic acid is an important feedstock for nylon 66 (PA66), whereas PA6 is manufactured using caprolactam.
