Australia Issues Final AntiDumping and Countervailing Duties on Chinese Light Gauge Steel Stud and Track

On 15 September 2026, the AntiDumping Commission of Australia released two official notices, announcing the final determinations in the antidumping and countervailing duty investigations concerning light gauge steel stud and track originating in China. This marks the conclusion of the dual investigation initiated in 2025.

Pursuant to Notice No. 2026/119, upon the adoption of recommendations from the Australian AntiDumping Commission by the Minister for Industry, Innovation and Science, antidumping duties will be imposed on the subject Chinese goods. Wenan Kaize Building Material Co., Ltd is subject to a 37.8 % antidumping duty, while all other noncooperating and remaining Chinese exporters face a 33.3 % rate.

The parallel countervailingduty final determination, published in Notice No. 2026/120 on the same date, imposes a 4.5 % countervailing duty on noncooperating and other Chinese exporters. For Wenan Kaize Building Material Co., Ltd, the countervailingduty investigation was terminated on 17 August 2026 as the subsidies received during the investigation period were de minimis; accordingly, the company is exempt from countervailingduty payments.

The subject goods are light gauge steel stud and track, metalliccoated, whether or not alloycoated, with maximum profile width and height of 170 mm and basematerial thickness not exceeding 0.69 mm.

Relevant Australian Customs tariff codes for the subject products are 7216.61.00.57, 7216.69.00.58, 7216.91.00.59, 7308.90.00.52, 7308.90.00.53, 7308.90.00.55 and 7308.90.00.56.

It should be noted that mediumtoheavy gauge light gauge steel stud and track, crossbraces and flexible guide channel components fall outside the scope of these duty measures.

Review of case timeline: On 30 June 2025, in response to an application lodged by Australian domestic producer Rondo Building Services Pty Ltd, the Australian AntiDumping Commission opened formal antidumping and countervailingduty investigations into imports of Chineseorigin light gauge steel stud and track. The dumping and subsidy investigation covered 1 April 2024 to 31 March 2025, whereas the injury assessment period commenced on 1 April 2021.

A preliminary antidumping determination was handed down on 25 May 2026. Provisional antidumping duties, secured by cash deposits, took effect on 26 May, with a uniform provisional rate of 37.8 % applicable to the named respondent and other Chinese exporters. No affirmative preliminary countervailing

determination was issued at that stage due to insufficient evidence, and the countervailing probe continued. On 17 August 2026, Australia issued its partial countervailing final ruling, terminating the countervailing investigation specifically against Wenan Kaize Building Material Co., Ltd. Dualremedy proceedings for the remaining parties proceeded until the two final determinations were issued on 15 September.

Following these final rulings, affected Chinese exporters shipping to Australia will be confronted with combined antidumping and countervailingduty barriers, which are expected to exert a direct impact on China’s lightgaugebuildingmaterial exports to the Australian market.
