The United States is adding and removing Canadian products from its 50% Section 338 tariffs, with the revised product lists taking effect September 15, 2026.
The United States has revised the scope of its 50% Section 338 tariffs on Canadian goods, adding some products and removing others from the additional duties effective September 15, 2026.
Two presidential proclamations issued September 8 set out the changes, relating to earlier U.S. actions on Canadian motor vehicles and alcoholic beverages.
Effective September 15, the revised tariffs apply to goods entered for consumption, or withdrawn from warehouse for consumption, on or after 12:01 a.m. ET.
The modified 50% Section 338 duties can stack with Section 232 duties, with the proclamations stating that the Section 338 duties, which took effect August 22 following a three-day suspension, apply in addition to duties imposed under Section 232.
Separately, the White House announced import bans on specified Canadian goods that will take effect September 29, 2026.
The revised lists extend the 50% tariff to a range of additional Canadian products.
Under the motor vehicle-related product list, additions include certain:
The alcohol-related product list separately adds numerous cheeses, certain fats and oils, hides, leather and furskins, and motorboats.
The exact tariff treatment depends on the applicable HTSUS classification.
The motor vehicle-related list removes the 50% tariff from eight tariff classifications, including certain salt, Portland cement, chemically pure sugars, refined lead, household paper products, switchgear, and fishing rod parts and accessories.
The alcohol-related list removes two classifications covering certain whiskies and liqueurs or cordials in containers holding more than four litres.
