On 7 October 2016, the Commissioner of the Australian Anti-Dumping Commission initiated an anti-dumping investigation on imports of zinc-coated (galvanised) steel from Malaysia, India and Viet Nam (Anti-dumping Notice No. 2016/105). The product subject to investigation is classified under the following HS code subheadings: 7210.49.00, 7212.30.00, 7225.92.00 and 7226.99.00. The complaint was lodged on 15 August 2016 by BlueScope Steel Ltd.

On 1 June 2017, the Australian authorities imposed provisional antidumping duties on imports of zinc-coated (galvanised) steel from India, Malaysia and Viet Nam. The rate of the duty imposed on imports from India is between 4% and 8.4% depending on the company. The rate of the duty imposed on imports from Malaysia is 14.5% or 16.5% depending on the company. The rate of the duty imposed on imports from Viet Nam is 8.4% or 14.2% depending on the company. Notably, the measure is imposed as the combined dumping and subsidy margin rates. As such, the provisional antidumping and countervailing duties are combined and imposed collectively. The combined duty imposed on imports from India is between 7.6% and 14.3% depending on the company. As no provisional countervailing duties were imposed on imports from Malaysia and Viet Nam the combined duties are equal to the antidumping duties mentioned above.

On 16 August 2017, the Australian authorities imposed definitive antidumping duties on imports of the subject good from India, Malaysia and Viet Nam. The duty is imposed as the combined dumping and subsidy rates. As such, the definitive antidumping and countervailing duties are combined and imposed collectively. The combined duty imposed on imports from India remains between 7.6% and 14.3% depending on the company. As no definitive countervailing duties were imposed on imports from Malaysia and Viet Nam the combined duties are equal to the antidumping duties. As such, the rate of the duty imposed on imports from Malaysia is 14.5% or 16.5% depending on the company. The rate of the duty imposed on imports from Viet Nam is 8.4% or 14.2% depending on the company.

On 6 October 2021, the Australian authorities announced the initiation of a sunset review of the definitive duty imposed on imports of the subject good from India, Malaysia and Viet Nam. This follows the application lodged on 13 September 2021 by BlueScope.
