Trade Advisory: New Section 338 Tariffs on Certain Canadian-Origin Products

Executive Summary

On July 20, 2026, President Trump issued three Presidential Proclamations under Section 338 of the Tariff Act of 1930, imposing an additional 50% ad valorem duty on specified Canadian-origin products. The measures are scheduled to take effect on August 19, 2026, at 12:01 a.m. EDT, and are intended to address what the Administration has identified as discriminatory treatment of U.S. commerce by Canada.

Key Changes for Importers

The proclamations add a 50% duty to designated Canadian goods and update the Harmonized Tariff Schedule of the United States accordingly. The additional duty applies on top of any other applicable duties, taxes, fees, and trade remedies unless a specific exclusion applies. Importantly, covered goods remain subject to the Section 338 duty even if they otherwise qualify for preferential treatment under the USMCA.

Covered Products

The three proclamations cover a broad range of Canadian-origin goods. Product categories referenced include dairy products, lactose and lactose syrups, certain sugars, syrups and bakery preparations, nonalcoholic beer, alcoholic beverages, agricultural products, chemicals, plastics, paper products, wood products, apparel, furniture, sporting goods, electronics, telecommunications equipment, machinery, and other consumer and industrial products. Importers should confirm coverage by reviewing the specific HTSUS provisions listed in the applicable annexes.

Excluded Products

The announced exclusions include most goods already subject to Section 232 measures, certain vehicles and vehicle parts, aluminum, steel, copper, civil aircraft and parts, semiconductors, patented pharmaceuticals, certain energy products, fish products, potash, and critical minerals. Importers should verify whether an exclusion applies before relying on it for entry planning or landed-cost assumptions.

Foreign Trade Zone Considerations

Covered merchandise admitted to a Foreign Trade Zone on or after the effective date generally must be admitted in Privileged Foreign Status. Companies using FTZ programs should review admission procedures, inventory controls, and downstream withdrawal planning before implementation.

Why It Matters

The new measures may create significant duty exposure for companies sourcing covered products from Canada. Because the Section 338 duties are generally cumulative and apply regardless of USMCA eligibility, importers should evaluate potential impacts on sourcing, landed cost, pricing, supplier contracts, customer commitments, and entry timing.

Companies importing dairy, alcoholic beverages, consumer goods, industrial materials, machinery, telecommunications equipment, furniture, sporting goods, and other covered products from Canada should begin reviewing exposure now to avoid unexpected duty liability beginning August 19, 2026.

Recommended Importer Actions

• Review HTS classifications against the applicable proclamation annexes.
• Identify Canadian-origin products that may be subject to the additional duty.
• Model potential landed-cost increases and pricing impacts.
• Assess sourcing alternatives, procurement timing, and customer contract considerations.
• Evaluate FTZ implications, including Privileged Foreign Status requirements.
• Consider available tariff mitigation strategies, including duty drawback where applicable.
• Monitor CBP implementation guidance and any amendments or clarifications before the effective date.

In Conclusion

Beginning August 19, 2026, many Canadian-origin imports may be subject to an additional 50% Section 338 duty. The measures reach beyond the headline dairy, alcoholic beverage, and motor vehicle sectors and may affect a wide range of consumer, industrial, and technology products. Importers should promptly confirm product coverage, quantify duty exposure, and determine whether mitigation options are available.
