The short answer: On October 14, 2026, Australia's trade remedies commission made a preliminary finding of dumping on aluminum windows and doors from China. Securities of 5.3% to 73.3% apply to most Chinese exports entered on or after October 15, 2026. A final report is due by December 16, 2026.
Verified as of November 6, 2026 against the Australian Trade Remedies Commission's Trade Remedies Notice 2026/147, which we read in full, and the parts of its Statement of Essential Facts 691 cited below. The commission was called the Anti-Dumping Commission until September 29, 2026.
This article covers what the notice says, which exporters pay which rate, what is still unknown and what to ask your supplier and forwarder to confirm in writing. It is based on those documents and on general good practice, not on any first-hand experience of this case. Your customs broker decides how it applies to your entries.
Why Does It Matter to an Australian Buyer?
- The cost is collected at entry. The Commonwealth requires and takes securities for goods exported from China and entered for home consumption on or after October 15, 2026, to cover interim dumping duty and interim countervailing duty that may become payable (TRN 2026/147).
- The rate depends on the exporter. The notice lists rates from 5.3% to 73.3%, and one exporter has no securities (TRN 2026/147). A supplier that is not named falls under a residual or an "all other" rate.
- It is not final. The Minister decides after the final report, which is due on or before December 16, 2026 (TRN 2026/147).
What Did the Commission Find?
An antidumping duty case asks whether goods are sold at less than their normal value, and a countervailing duty case asks whether a foreign government subsidizes them. Commissioner David Latina initiated Investigation 691 on November 25, 2025, after an application from Ventora Group and the Australian Glass and Window Association, and set out his preliminary findings on October 14, 2026 (TRN 2026/147).
He found sufficient grounds for a dumping duty notice on exports by all Chinese exporters except Altop Facade Co., Ltd, and for a countervailing duty notice on exports by non-cooperative entities. For the other exporters he found the subsidy margin negligible or nil (TRN 2026/147). The investigation period was July 1, 2024 to June 30, 2025 (SEF 691).
| Exporter | Preliminary dumping margin | Preliminary subsidy margin | Effective security rate |
|---|---|---|---|
| Altop Facade Co., Ltd | Negative 47.4% | 1.5% | None |
| Broad Windows and Doors and Curtain Wall System Co., Ltd | 24.4% | 0.7% | 24.4% |
| Guangdong Kete Facadetech Co., Ltd | 12.1% | 0.8% | 12.1% |
| Zhuhai Yipeng Technology Co., Ltd | 51.6% | Nil | 51.6% |
| Foshan AMJ Windows and Doors Co., Ltd | 5.3% | Nil | 5.3% |
| Yuanjiang Facade Co Ltd | 34.8% | 1.0% | 34.8% |
| Residual exporters | 24.4% | 0.7% | 24.4% |
| Uncooperative and all other exporters | 70.4% | 2.9% | 73.3% |
The notice says the actual security liability may be higher than the effective rate because of a number of factors, and points affected parties to business.gov.au. It lists these exporters as a matter of public record; this article does not recommend or rank any of them (TRN 2026/147).
Which Products Are Covered?
The goods are aluminum windows and doors, fully or partly assembled, including their frames, panels and sashes, with or without glass, thermally broken or not, with or without hardware, up to dimensions set out in the SEF. Curtain wall products are excluded (SEF 691). The SEF lists tariff subheading 7610.10.00, statistical code 12, but says the codes are for reference only and the goods description is what counts (SEF 691). We do not reproduce the dimension limits here; read them in the SEF before you decide that a product is outside the case.
What Is Still Unknown?
- The final decision. The Commissioner reports to the Minister on or before December 16, 2026, and the Minister then decides whether to publish a dumping duty notice and a countervailing duty notice and at what level (TRN 2026/147).
- The final rates. The SEF says it may not represent the Commissioner's final views, and interested parties have 20 days to respond to it (SEF 691).
- Retroactive duty. The notice says that if retrospective notices are imposed under section 269TN of the Customs Act 1901, the final notices will also include duties imposed retrospectively (TRN 2026/147).
- Your own liability. We did not find how the commission will treat goods already in transit before October 15, 2026. Ask your broker.
What Should a Buyer Ask the Supplier and the Forwarder to Confirm?
This section is general advice, not a rule from the documents.
- The exact exporter name that will appear on the commercial invoice and the export declaration, the same as on the quote, the proforma invoice and the payment (see what to check on a proforma invoice and telling a real factory from a trading company).
- Who pays the securities and any final duty, and what happens to the price if the rate changes. With delivered terms, ask what the price includes and until when it is valid (see which price term to ask a Chinese supplier to quote).
- The product description and tariff number the supplier uses for each item, so your broker can compare them with the goods description (see the documents to request from a Chinese manufacturer).
- Your open orders and their expected entry dates, so you can tell which ones are entered on or after October 15, 2026.

It cannot decide whether your product is in scope or what duty applies. It can confirm what is on the supplier's side of the paperwork: that the exporter named on the documents is the company that makes the goods, where the production happens and that the goods match the description your broker will use. See our factory supervision service for orders in production and our construction products page if you buy building materials.

What Do the Documents Not Tell You?
They do not tell you whether your windows are covered, what you would pay at the end of the case or whether any supplier is reliable. They say nothing about quality, and a low or zero rate says nothing about the exporter's performance.
What Should You Do Next?
- Ask your customs broker to read the goods description and tell you whether your products may be covered.
- List your open orders for aluminum windows and doors from China with expected entry dates.
- Get the exporter name and the product description from each supplier in writing.
- Write the price validity and duty responsibility into the proforma invoice.
- Check any new supplier before you pay, see the supplier verification checklist. For a similar case with a different schedule, see the duties on Chinese van trailers.
