Australian Trade Remedies Commission issues preliminary affirmative determination on dumped and subsidised Chinese aluminium windows and doors

Executive Summary

The Australian Trade Remedies Commission (ATRC) issued a preliminary affirmative determination on 14 October 2026, finding apparent grounds for dumping and countervailing duty notices against Chinese aluminium window and door exporters. The Commonwealth will require securities on affected imports entered for home consumption on or after 15 October 2026.

This determination marks a significant procedural milestone. The ATRC was renamed from the Anti-Dumping Commission on 29 September 2026 and continues to administer the investigation initiated on 25 November 2025.

Bottom Line

The ATRC's preliminary affirmative determination finds apparent grounds for dumping and countervailing duty notices against Chinese aluminium window and door exporters, excluding Altop Facade. The Commonwealth has announced that it is to require and take securities on affected imports entered for home consumption on or after 15 October 2026, at rates between 5.3% and 73.3% depending on the exporter. The Commissioner's final recommendations are due to the Minister on or before 16 December 2026, after which the Minister decides on final duty notices and measure levels. Cresthaven reading: Australian importers currently sourcing from non-cooperative or unidentified Chinese exporters carry the highest immediate security exposure at 73.3%, with the final ministerial decision representing the next material inflection point for the sector.

Key Regulatory Signals

• Securities Imposed on Most Chinese Exporters from 15 October 2026: The Commonwealth has announced it will require and take securities on Chinese aluminium windows and doors entered for home consumption on or after 15 October 2026. Rates range from 5.3% for Foshan AMJ to 73.3% combined for uncooperative and all other exporters. Cresthaven reading: Australian importers sourcing from affected exporters face immediate cash-security obligations at the border before goods clear customs.
• Altop Facade Excluded from Duty Exposure: The ATRC found that exports from Altop Facade Co., Ltd were not dumped, recording a negative dumping margin of 47.4%. Altop faces no interim dumping or countervailing duty securities under the preliminary determination.
• Non-Cooperative Exporters Face the Highest Combined Rate: Uncooperative and all other exporters are subject to a combined interim dumping and countervailing duty security rate of 70.4% and 2.9% respectively, for an effective rate of 73.3%. The ATRC notes the actual security liability may exceed the stated effective rate depending on individual circumstances.
• Final Recommendations Due by 16 December 2026: The Commissioner is required to report to the Minister for Industry and Innovation and Minister for Science with final recommendations on or before 16 December 2026. The Minister will then decide whether to publish a dumping duty notice and countervailing duty notice, and the level of any measures to be imposed.
• Retrospective Duties Remain a Possibility: The notice states that if dumped or subsidised goods give rise to retrospective notices under the relevant customs provisions, any final dumping duty and countervailing duty notices will also include retrospectively imposed duties.
