Canada / U.S. Tariff Calculator
Estimate the additional border tariff on a shipment using verified current presets. Updated for the U.S. Section 338 measures effective August 22, 2026.
Three Section 338 measures took effect at 12:01 a.m. ET on Aug. 22. They apply only to listed Canadian goods. Not every Canadian export.
Canada announced matching countermeasures, but the new product schedule and implementation details were not yet published when this page was updated.
Separate U.S. Section 232 measures and Canada’s existing 25% counter tariffs on specified steel, aluminum and vehicles require tariff line verification.

What changed on August 22
It applies to the tariff lines listed in the three U.S. Section 338 proclamations. The covered range includes products from wine to hockey sticks to cement.
For goods on the Section 338 lists, the additional 50% duty applies even when the product otherwise qualifies under CUSMA/USMCA.
The White House identifies energy, potash, Section 232 goods and certain fish and critical minerals among the exclusions from these new duties.
The government announced dollar for dollar retaliation. Until the legal order and tariff item list are published, any exact new Canadian rate by product would be speculation.
