U.S. Expands Tariffs and Introduces Import Bans on Canadian-Origin Goods

The United States has announced a new round of trade measures affecting certain Canadian-origin goods. Five presidential proclamations issued on September 8 modify the products subject to existing 50% Section 338 tariffs and introduce import bans covering specified alcoholic beverages, dairy products and motorcycles.

The tariff changes take effect September 15, 2026. The import bans take effect September 29, 2026.

What’s Changing

Motor vehicles-related tariff list

Beginning September 15, the United States will revise the Canadian-origin products subject to the existing 50% additional tariff under the motor vehicles action.

• Products added include certain paper goods, steel and aluminum products, and dairy products.
• Products removed include certain salt products, toilet paper and tissues, sheets, and sporting goods.

The 50% tariff is additional to any other applicable duties, including certain Section 232 duties. Review the motor vehicles proclamation and product annexes.

Alcohol-related tariff list

A separate proclamation changes the Canadian-origin products subject to the existing 50% tariff under the alcoholic beverages action.

• Products added include certain dairy, leather and vehicle products.
• Certain liqueurs are being removed from the tariff list.

These changes also take effect September 15. Review the alcoholic beverages proclamation and product annexes.

New import bans

Beginning September 29, specified Canadian-origin goods will be prohibited from importation into the United States. The bans cover:

• Certain alcoholic beverages across 53 tariff subheadings
• Certain dairy products
• Certain motorcycles

Goods covered by the bans that were imported before September 29 but have not yet been entered for consumption or withdrawn from a warehouse will remain subject to the applicable 50% tariff rather than the import prohibition.

Review the official proclamations for alcoholic beverages, dairy products and motorcycles.

What Merchants Should Do Now

Merchants shipping Canadian-origin goods into the United States should:

1. Review affected SKUs against the HTSUS subheadings included in each proclamation’s annex.
2. Confirm product origin rather than relying solely on the country of export or fulfillment location.
3. Recalculate landed costs for products entering the United States on or after September 15.
4. Identify products subject to the September 29 import bans and pause affected orders before they enter the shipping network.
5. Review inventory already in transit or held in a U.S. customs warehouse to determine which tariff or import treatment will apply.

FlavorCloud is updating its product and compliance systems to reflect these changes. Because the measures are tied to specific tariff classifications, merchants should confirm the applicable HTS code and country of origin for each affected product before shipping.
