Canada's 15–50% counter‑tariffs hit U.S. goods since 8 September

Market Context & Direct Impact

Canada's surtaxes on U.S.-origin goods have applied since 8 September. The Canada Border Services Agency's Customs Notice 26-23 applies surtaxes of 15%, 25% or 50% of value for duty to certain goods from the United States, effective 8 September 2026. Each product's rate generally mirrors the U.S. tariff on that product under Section 338 and Section 232. The surtax reaches only goods eligible to be marked as U.S. origin under CUSMA marking rules, so goods from Puerto Rico, Guam and the other U.S. territories fall outside it.

The scope is wide, yet it touches a small slice of trade. FreightWaves reports the measures cover roughly C$27.6 billion ($20 billion) of U.S. imports, about 8% of Canada's imports from the U.S. Steel, aluminum, clothing, furniture, dairy and industrial equipment are among the affected lines, and forklifts carry 15%. Bloomberg reported that Canada would double its counter-tariffs on U.S. steel and aluminum to 50%. The duties answer U.S. tariffs of 50% on Canadian goods, so the dispute is two-way and still open. Bloomberg reports Prime Minister Mark Carney says Canada will reach a trade deal with the U.S., while U.S. tariffs show no end in sight.

Core Executive Takeaways

• Origin data decides dutyShippers that cannot prove U.S. origin and clean product identifiers face the surtax at the border, according to FreightWaves' James Edge.
• Dual-node fulfilment spreadsEdge describes one client that added a Canadian warehouse, which he says many other shippers are copying.
• Volatility, not a resetEdge expects tariff swings to ease gradually, but rates to stay above what importers want, so plan for a higher cost base.

Strategic Playbook

1. 1
   Audit origin before entry

   Verify country of origin and product identifiers for every U.S.-built SKU against the CBSA schedules before the next Canadian entry, so the 15%, 25% or 50% surtax is correctly declared.

2. 2
   Model a Canadian node

   Run the landed-cost comparison of a second Canadian warehouse against paying surtaxes at the border, using each product's rate, before committing inventory for the northbound lanes.
