Canadian alcohol 50% duty scope changes take effect September 15
A proclamation revises the list of Canadian products subject to the 50% additional duties previously imposed under Section 338. Some products are added to the duty list and some are removed, effective September 15, 2026.
What this affects
CanadaThe update
This proclamation modifies the scope of Canadian products covered by the additional duties imposed under Proclamation 11046. It states that certain products listed in Annex I, Part A remain subject to the additional 50% ad valorem duty, while certain products listed in Annex I, Part B are no longer subject to that duty.
The action is taken under Section 338 of the Tariff Act of 1930, which the proclamation cites as authority to offset discrimination against the commerce of the United States. The proclamation says the change better serves the public interest while still offsetting the burden or disadvantage on U.S. commerce. It also states that these duties apply in addition to duties imposed under Section 232 of the Trade Expansion Act of 1962.
The changes apply to goods entered for consumption, or withdrawn from warehouse for consumption, on or after 12:01 a.m. eastern time on September 15, 2026. The Harmonized Tariff Schedule of the United States is modified through Annex II, and CBP is authorized to issue implementing rules, guidance, instructions, and determinations.
Impact
Importers of Canadian goods need to confirm whether their products were moved into or out of the 50% additional duty scope. The change can affect landed cost immediately and may also stack on top of other applicable duties, including Section 232 measures named in the proclamation.
What to watch
The proclamation changes scope through annexes not reproduced in the text provided here, so product coverage cannot be determined from this source excerpt alone. CBP may also publish technical or ministerial HTSUS corrections in a later Federal Register notice.
