On August 22, 2026, the United States imposed 50% additional ad valorem tariffs on about $20 billion worth of Canadian goods under Section 338 of the Tariff Act of 1930. This was the first modern use of Section 338 authority, which allows the President to impose up to 50% duties to offset what they deem as discriminatory or unequal treatment by a foreign country toward U.S. commerce.
The tariffs were originally scheduled for August 19, 2026, but on August 18 President Trump announced a three-day suspension while U.S.–Canada trade talks continued.
Negotiations, which had been progressing, stalled on August 21–22 as Canada’s Prime Minister Mark Carney suspended talks and recalled negotiators.
The U.S. Trade Representative is pushing for Canada to finalize a Trade deal.
On July 20, 2026, President Trump issued three Presidential Proclamations under Section 338 of the Tariff Act of 1930 (19 U.S.C. § 1338) imposing an additional 50% ad valorem duty on specified Canadian-origin products. Section 338 authorizes the President to take retaliatory trade actions when a foreign country is found to discriminate against U.S. commerce. The new tariffs are scheduled to take effect on August 19, 2026, at 12:01 a.m. EDT and are intended to offset the burden and disadvantage imposed on U.S. exports by Canada's alleged discriminatory measures.
The proclamations impose an additional 50% ad valorem duty on designated Canadian products and modify the HTSUS accordingly. The duties apply in addition to any other applicable duties, taxes, fees, and trade remedies unless specifically excluded. The measures apply regardless of whether the goods qualify as originating under the USMCA.
The three proclamations cover a broad range of Canadian products, including: 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 numerous other consumer and industrial goods.
Most Section 232-covered goods, certain vehicles and vehicle parts, aluminum, steel, copper, civil aircraft and parts, semiconductors, patented pharmaceuticals, certain energy products, fish products, potash, and critical minerals. FTZ Impact Affected products admitted to an FTZ after the effective date generally must be admitted in Privileged Foreign Status.
These measures represent one of the most significant uses of Section 338 authority in decades and create additional duty exposure for importers sourcing affected products from Canada. Because the duties apply regardless of USMCA eligibility and are generally cumulative with other applicable duties, companies should immediately evaluate sourcing, landed cost, pricing, and contractual impacts.
Companies importing dairy products, alcoholic beverages, consumer products, industrial materials, machinery, telecommunications equipment, furniture, sporting goods, and other covered products from Canada may experience substantial increases in duty liability beginning August 19, 2026.
Importers should review HTS classifications against the covered Annex provisions, identify Canadian-origin products that may be impacted, assess landed-cost increases and customer pricing impacts, review sourcing alternatives and procurement strategies, evaluate FTZ implications, including Privileged Foreign Status requirements, consider tariff mitigation opportunities, including duty drawback where available, monitor CBP implementation guidance and any future amendments to the proclamations.
Beginning August 22, 2026, a broad range of Canadian imports may become subject to an additional 50% Section 338 tariff. The actions target products across the dairy, alcoholic beverage, agricultural, consumer, industrial, and technology sectors and apply regardless of USMCA preferential treatment. Importers should promptly assess product exposure, duty impacts, and available mitigation strategies.

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.
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.
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.
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.
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.
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.
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.
