UPDATE: EU slaps provisional AD duties of up to 51.5% on Chinese copper tubes

Copper tubes manufactured by Ningbo Jintian Copper Tube Co., Ltd. will face a provisional duty of 33.5%, while all other Chinese imports will be subject to 51.5%. The lower individual rate applies only if a valid commercial invoice meeting the regulation's requirements is presented.

The investigation also covers Cu tube imports from Mexico, Vietnam and Uzbekistan, with provisional duties set at 18.2% for Mexican imports, 12.3–14.4% for Vietnamese imports and 5.6–11% for Uzbek imports.

According to the Commission's preliminary findings, based on Eurostat data and questionnaire responses from sampled exporters, imports of copper tubes from the four countries rose 32% to 28,939 tonnes in 2025 from 21,864 tonnes in 2022. Their combined share of the EU free market rose by about 8 percentage points to 25–28% over the same period, the finding said. 

Imports from Vietnam increased by 65% between 2022 and 2025, while those from Mexico rose by 7%. Chinese imports remained broadly stable, the Commission said.

The products concerned are pipes and tubes of refined copper, in level-wound coils, whether smooth or with inner grooves, and not further processed. They fall under CN code ex 7411 10 90 and TARIC code 7411 10 90 10, as Mysteel Global reported.

The investigation was initiated on March 12 this year following a complaint lodged by the EU Copper Tubes Defence Committee on January 26. The dumping investigation period ran from January 1 to December 31 2025, while the injury assessment period covered January 1 2022 to December 31 2025.
