What is NOT covered by the Sept 8 counter-tariffs
- US automobiles and auto parts — NOT on the Sept 8 list. They remain under the separate existing 25% Canadian counter-tariff order.
- Fish and seafood (HS Ch. 03) — removed in the Aug 26 revision; no seafood items remain on the list.
- Oil, gas and potash — not on the list.
- Goods of non-US origin — even if shipped through the US, under the CUSMA marking test.
- US goods already in transit to Canada on September 8, 2026.
Why the US-Canada trade talks are stalled
Canada suspended negotiations on August 22, 2026 after the final round collapsed, and recalled its negotiating team from Washington. PM Mark Carney said the US "asked too much and offered too little" and that Canada will match the US Section 338 tariffs "dollar for dollar, rate for rate." USTR Jamieson Greer said there were no plans to resume talks as of late August, and Canadian officials see little chance of resumption before the November US midterms.
Bottom line for importers: the Sept 8 tariffs are scheduled to take effect as announced, but both the date and the product list are conditional on the talks. If a deal lands, rates could be reduced, suspended, or removed — and the calculator presets on this site are built to be updated without a risky deployment.
What importers should do before September 8
- Verify your HS code against the official 629-item list — category shorthand (e.g., "50% steel") is not enough; the tier varies at the 8-digit line level.
- Check origin and timing. The surtax applies only to US-origin goods (CUSMA marking regulations), and US goods already in transit on Sept 8 are exempt.
- Watch for the CBSA Customs Notice. As of Aug 31, 2026 the CBSA had not yet published the implementing notice for the Sept 8 surtax — Finance Canada defers administration to CBSA, and a notice has accompanied every prior surtax order.
- Model both directions — the 50% US duty on Canadian-origin goods (in effect Aug 22) and the new Canada-side tiers on US-origin goods (Sept 8) are separate costs.
- Plan for volatility. Remission relief (steel at 25%) is intended pending Governor in Council approval, and a deal could change the whole list.
