What does the Australian anti-dumping measure mean for aluminium window orders?
By Sheng Xu · 16 October 2026
A preliminary determination in the Australian anti-dumping case covering aluminium windows and doors has introduced provisional securities on affected imports. Securities are set per exporter rather than as one rate across the board, so two suppliers shipping comparable product can face very different numbers, and importers must lodge the security at the border before goods are released. Provisional rates run from 5.3 to 73.3 per cent depending on the exporter, under Trade Remedies Notice TRN 2026/147. The determination is preliminary and the final outcome has not been confirmed.
Why it is stopping orders rather than just raising prices
A security is lodged at the border on the full value of the consignment, before the goods are released, so the immediate effect is on cash rather than on the final cost of the job. An importer who priced a package on thin margins may not have the working capital to clear their own container, which is why some orders have been returned rather than repriced.
The second effect is on certainty. A quote issued before the determination may no longer be serviceable, and a supplier who cannot state a landed cost often withdraws rather than commits. For a builder that leaves a schedule with no window package behind it, which is usually more expensive than the price difference being argued over.
What to ask a supplier right now
Ask who actually manufactures the product and whether they are the exporter of record, because a trading company reselling another factory output may be exposed to a rate it neither controls nor can see. Ask for a landed cost in writing rather than a verbal reassurance. Ask to see the AS 2047 certificate for the specific system being supplied, since a disrupted supply chain is when substitutions tend to get made quietly. Finally, ask what happens to the order if the final determination moves the rate.
If a project is already under way
Get the window schedule and the energy report in front of a second supplier early, before deciding whether to switch. Requoting a full package takes time and the schedule is the long pole, so starting that process is not a commitment. Confirm the compliance question before the commercial one: a cheaper replacement that fails documentation costs more than the package it replaced.
The figures above reflect a preliminary determination only and the final outcome has not been confirmed. Nothing here is legal, customs or financial advice.
