The Section 338 action reaches well beyond automobiles, exposing Canadian yarns, fabrics, nonwovens, apparel and technical-textile products to a substantial new US cost barrier.
The United States will impose an additional 50% tariff on selected Canadian products from August 19, 2026, including a significant range of textile and textile-containing goods. The measure was announced by the White House on July 20 under Section 338 of the Tariff Act of 1930 in response to what the administration describes as discriminatory Canadian treatment of US exports.
USMCA status does not provide protection
Unlike many recent trade actions, covered products do not escape the new duty simply by qualifying for preferential treatment under the US-Mexico-Canada Agreement. The White House says the Section 338 tariffs apply to listed Canadian goods regardless of USMCA origin status. They are also additional to existing duties, taxes and charges, although products already subject to specified Section 232 measures are excluded.
The administration issued three separate actions covering perceived Canadian discrimination involving motor vehicles, alcoholic beverages and dairy products. The textile exposure arises particularly from the product list attached to the motor-vehicle action.
Textile scope is surprisingly broad
Selected tariff lines include polyester filament and staple woven fabrics, synthetic staple-fibre yarn, several categories of nonwovens, narrow woven fabrics, coated and laminated textiles, technical textiles, synthetic knitted fabrics and apparel. Cotton waste and certain raw cotton classifications, carpets, cordage and leather goods also appear within the covered schedule.
The measure should not, however, be described as a blanket 50% tariff on all Canadian textiles. Liability depends on the specific Harmonized Tariff Schedule classification of the imported product.
Buyers need immediate classification review
For Canadian textile manufacturers, the tariff could materially weaken competitiveness in the US market, particularly for commoditised products where a 50-percentage-point duty increase cannot readily be absorbed through margin.
US importers should now identify Canadian-origin goods against the listed HTS codes, recalculate landed costs and review contracts covering tariff allocation. Canadian mills may need to examine alternative markets, product repositioning or US-based manufacturing arrangements.
The next development to watch is whether Washington modifies the action before August 19 or Canada changes the policies that triggered it. Section 338 gives the US president authority to reduce, amend, suspend or revoke the tariffs as circumstances change.
