What US tariff does your product pay?

Type a product word such as honey, whisky or plywood, or paste an HS code straight from your product data. The check reads the code against the published American lists. It shows the 50% Section 338 duty and the chapter 99 programmes that stand apart from it, plus the standing order on goods that do not qualify under CUSMA.

Headings where every code is taxed
Headings that split, where six digits cannot settle it

554 Section 338 tariff codes sit inside 373 six-digit headings.

What this can and cannot tell you

Section 338 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 from Section 338. The 35% order does exempt a good that qualifies.
Section 338 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.

Send your product list, from Shopify, from a spreadsheet, or from your own system. I read it by hand and return the codes that are hit, the headings that need a broker, and the dollars at risk.
