On October 15, 2025, the Canadian Border Services Agency (CBSA) updated Customs Notice 25-28 CBSA to clarify that steel and aluminum imported as of September 22, 2025, will require specific documented evidence of country of melt and pour (COM) or country of smelt and cast (CSC) proving they are not from China, in order to avoid a surtax.
The Government of Canada implemented the Steel Goods and Aluminum Goods Surtax Order on July 31, 2025, to address risks from global overcapacity and non-market practices in the steel and aluminum sectors, particularly linked to China. This measure also responds to restrictive trade actions by the United States under Section 232 of the Trade Expansion Act.
This surtax aims to protect Canadian industry from unfair trade practices and maintain market stability.
