What this can and cannot tell you
- Rate
- 50% ad valorem, added on top of the ordinary duty.
- Charged on
- The entry date, not the ship date. Goods already in transit are caught.
- CUSMA
- No relief.
- In force
- 22 August 2026, by Proclamation 11056.
- This tool
- Stops at six digits. I am not a licensed US customs broker, so I do not pick the seventh and eighth digit for your product. A split heading reads Review, and a broker settles it.
- Also searched
- The other United States programmes a Canadian good can fall under: steel, aluminium and copper, vehicles and vehicle parts, trucks and buses, softwood, upholstered furniture, kitchen cabinets, semiconductors.
- Not searched
- Antidumping and countervailing duties. Patented pharmaceuticals, which heading 9903.04.60 charges at 100 percent by patent status rather than by code.
- Source
- CBP message CSMS 69606660, attachment Section 338 Canada HTS List Final, 21 August 2026. The other programmes and every rate come from the chapter 99 U.S. notes in the USITC tariff schedule, Revision 17 (2026). Code descriptions come from the same schedule.
Nothing here is customs advice or legal advice. Check your own classification with a licensed broker before you file.
