Canada: Additional 50% Duty on Vehicles, Dairy and Alcoholic Beverages Effective August 19, 2026 (Section 338)
Three presidential proclamations published on July 23, 2026 impose an additional 50 percent ad valorem duty on listed Canadian-origin goods under Section 338 of the Tariff Act of 1930. Each creates a chapter 99 heading that adds 50% to the applicable subheading: 9903.03.12 (FR 2026-14991), 9903.03.13 (FR 2026-14992) and 9903.03.14 (FR 2026-14997), with the covered subheadings listed in U.S. note 51. The duties take effect for goods entered for consumption, or withdrawn from warehouse for consumption, on or after 12:01 a.m. eastern time on August 19, 2026. Nothing is collectible before that moment. IMPORTANT ON SCOPE: the proclamations are captioned for the disputes that prompted them (alcoholic beverages, dairy, motor vehicles), but the covered-product annexes are separate retaliation lists and in two of the three cases bear no relation to the caption. Classify against Annex II or CBP guidance, not against the sector in the title. Gateway status: the duty is modelled in every Gateway duty engine and is date-gated to the effective moment, so it shows as upcoming until August 19. The dairy list is loaded in full. The other two annexes are published only as page images, so a Canadian line outside the loaded list is reported as unverified rather than clear. Those two lists have now been extracted from the proclamation PDFs and verified against the tariff schedule, and are being wired in ahead of the effective date.
