On October 2, 2025, the Canada Border Services Agency (CBSA) issued its fourth sunset review final determination of anti-dumping (AD) and countervailing duty (CVD) measures on carbon steel fasteners originating in or exported from China, and AD measures on the same goods from Taiwan.

The CBSA determined that dumping and subsidization of the subject products would likely continue or resume if the current measures expire.

The Canadian International Trade Tribunal (CITT) will carry out an investigation to assess if the expiration of these measures is likely to cause injury to the domestic industry and will announce its decision by March 11, 2026.
