Section 338 Tariffs on Canadian Imports Revised: Products Added and Removed Effective October 30, 2026

The Trump administration has revised the list of Canadian products subject to the 50 percent tariffs imposed under Section 338 of the Tariff Act of 1930. Effective October 30, 2026, the changes remove certain products from coverage while adding others, potentially creating significant cost implications for U.S. importers.

Businesses importing goods from Canada should promptly review the revised product list, confirm tariff classifications, and assess potential impacts on pricing, sourcing strategies, and supply-chain operations.

Understanding the Revised Section 338 Tariffs on Canadian Imports

On July 20, 2026, President Trump signed three supplementing presidential proclamations under Section 338 Tariffs, which imposed a 50 percent import tariff on certain products from Canada. The scope of these tariffs, which covered products ranging from wine to hockey sticks, were subsequently modified on September 8.

Which Canadian Products Are Affected by the Revised Tariffs?

The revised tariff schedule both removes products from and adds products to the list of goods subject to the 50 percent duty.

Products removed from the tariff list include plywood sheets, specified paper products, refrigeration equipment, and certain packing crates and boxes.

Products newly subject to the 50 percent tariff include cocoa powder, shampoos and certain soaps, carpets and textile floor coverings, and more.

The full list of modifications and product descriptions is available in Annex I. Importers should review this list carefully.

Steps Importers Can Take Before the October 30 Effective Date

The refined scope of tariffs on Canadian products may substantially increase or decrease costs for importers of affected goods. Accordingly, importers should consider taking the following actions:

• Plan ahead for the October 30 implementation date. Taking action before the new tariffs become effective may help mitigate increased duty costs and minimize supply-chain disruptions.
• Review product classifications. Check your product against the revised list using your product’s HTSUS code as many products have been taken off of the lists.
• Watch for retaliatory measures. Watch for Canada’s retaliation as the Canadian government is likely to pursue countermeasures under its own reciprocal-tariff law.

Given the breadth of the revised tariff list and the substantial duty rate, importers should review affected products as soon as possible. Early assessment of tariff exposure, supply-chain implications, and potential mitigation strategies may help reduce disruption once the changes take effect.
