The Australian Anti-Dumping Commission issued an affirmative final anti-dumping (AD) determination against certain strata steel bolts imported from China.

The duty rates are set at 15.1% for Anto Mining Equipment Co., Ltd. and 3.5% for Sandvik Jining Rocbolt Technologies China Co., Ltd. Huanghua Tanrimine Metal Support Co., Ltd receives a 0% rate, whereas all other Chinese exporters face a 24.8% duty.

Domestic firms DSI Underground Australia Pty Limited and Jennmar Australia Pty Limited requested the original AD and countervailing duty (CVD) probes in December 2024. The authority evaluated dumping activities from October 1, 2023, to September 30, 2024, assessing domestic injury starting October 1, 2020. This ruling finalizes the temporary security-based AD duties of 7.2% to 35.2 % introduced during the preliminary phase in December 2025.

The affected goods are under HS codes 7304.51.00.30, 7308.40.00.05, 7318.15.00.56, 7318.15.00.65, 7318.24.00.22, 7318.19.00.03, and 7318.19.00.19.
