Capral backs provisional duties of up to 73.3% on Chinese aluminium windows and doors

Australian aluminium producer Capral has welcomed proposed trade measures against Chinese aluminium window and door imports, following preliminary findings of dumping and subsidies that have put pressure on local manufacturers.

The Australian Trade Remedies Commission's investigation found dumping margins of 5.3 per cent to 70.4 per cent on certain imports. Provisional measures introduced on October 15 require importers to provide financial security against potential duties of up to 73.3 per cent.

The investigation covers fully and partially assembled aluminium windows and doors imported from China between July 2024 and June 2025. Capral said the findings were important for Australia's domestic aluminium supply chain, particularly businesses involved in manufacturing windows and doors.

Tony Dragicevich, Capral’s Managing Director and Chief Executive Officer, said, “These are preliminary findings, but they are important. The Commission has recognised that dumped and subsidised imports have caused real financial harm to Australian window and door manufacturers.”  

Under the preliminary measures, a 24.4 per cent rate applies to cooperating exporters that were not individually examined, while a 73.3 per cent rate applies to uncooperative and other unlisted exporters. These categories account for around 71 per cent of the value of Chinese imports included in the investigation. 

Individually assessed exporters have been assigned separate rates, while one exporter is exempt from the preliminary measures. The Commission also identified subsidies to some Chinese exporters, resulting in an additional 2.9 per cent duty component for those companies.

Dragicevich further said, “Australian manufacturers can compete. What they need is a market where prices reflect fair competition. These preliminary measures begin to address that imbalance while the investigation continues.” 

The company said the impact of finished window and door imports extends beyond fabricators to aluminium extruders, glass processors, hardware suppliers and transport businesses.

The investigation is continuing. Submissions close on November 3, and the Commission's final report is due by December 16, 2026. The Minister will then decide whether to introduce final trade measures. Capral plans to submit its views during the remaining investigation.
