US Bans & Tariff Changes on Canadian Autos, Dairy, and Alcohol

Key Points

• Federal Register notices dated September 13, 2026 announce outright import exclusions on certain Canadian products in three sectors: motor vehicles, dairy, and alcoholic beverages.
• Two separate scope-modification notices simultaneously adjust which Canadian products are subject to additional duties tied to Canadian discrimination against U.S. commerce in the motor vehicle and alcoholic beverage sectors.
• These actions are framed as retaliatory countermeasures against continued Canadian discrimination against U.S. commerce, not as general Section 232 or Section 301 measures.
• Importers of Canadian-origin autos, auto parts, dairy, and alcohol face the most immediate exposure and should review affected HTS lines against the published notices before filing new entries.
• USTR is separately seeking comments through a parallel Federal Register notice to identify foreign trade barriers for the 2027 National Trade Estimate Report, which may inform future actions.

The U.S. government published five Federal Register notices on September 13, 2026 targeting Canadian imports across three industries. Two categories of action are in play: outright exclusions prohibiting importation of certain Canadian products, and modifications to the scope of existing additional duties. The links throughout this article go to the primary documents themselves, including the proclamations and Federal Register notices. Read the source.

What changed

Three Federal Register notices establish import exclusions for specific Canadian products in response to what the U.S. government characterizes as Canada's continued discrimination against U.S. commerce. The affected sectors are motor vehicles, dairy, and alcoholic beverages. An exclusion means the listed products cannot legally enter U.S. commerce from Canada, going beyond an additional duty to an outright prohibition on importation.

Two additional notices modify the scope of the additional duties already in place targeting Canadian products in the motor vehicle and alcoholic beverage sectors. Scope modifications can expand or contract which HTS subheadings and product descriptions are subject to the additional rate, and the exact changes must be read directly from each notice.

Affected sectors and scope of the exclusions

The three exclusion notices cover distinct product categories:

• Motor vehicles: Certain Canadian-origin motor vehicle products are excluded from importation. See the motor vehicle exclusion notice for the precise product list and HTS coverage.
• Dairy: Certain Canadian dairy products are excluded from importation. See the dairy exclusion notice for the full scope.
• Alcoholic beverages: Certain Canadian alcoholic beverage products are excluded from importation. See the alcoholic beverages exclusion notice for details.

In each case the legal basis is Canada's continued discrimination against U.S. commerce in the respective sector, not a general trade remedy statute. Importers should not assume that existing Section 321 de minimis treatment, bonded warehouse strategies, or Foreign Trade Zone admissions automatically resolve an entry-prohibition situation.

Scope modifications to existing additional duties

Alongside the outright exclusions, two scope-modification notices revise which Canadian products fall under the additional duties that were previously imposed:

• Motor vehicles: The motor vehicle scope modification alters which products of Canada are subject to the additional duties imposed to offset Canadian discrimination in the auto sector.
• Alcoholic beverages: The alcoholic beverages scope modification makes parallel adjustments for the beverage sector.

Scope modifications take effect as of their Federal Register publication date unless the notice states otherwise. Entries filed before and after the effective date are treated differently, so brokers must determine the correct rate or prohibition status by entry date, not by shipment date.

Interaction with other tariff provisions

These measures layer on top of any existing USMCA tariff treatment, Section 232 duties on steel and aluminum, and any other Canada-specific actions. Canadian-origin goods that previously entered duty-free or at reduced rates under USMCA may now be subject to additional duties or an outright ban depending on product classification. Importers and brokers should cross-check all active special-program claims against the updated scope language in each notice before claiming preferential treatment.

What importers should do

• Pull every open purchase order and shipment for Canadian-origin motor vehicles, auto parts, dairy products, and alcoholic beverages and compare the HTS classifications against the product lists in all five Federal Register notices.
• For goods that fall within an exclusion, halt or redirect shipments immediately and consult the exclusion notice's effective date before releasing any goods from a bonded facility.
• For goods subject to a scope modification of additional duties, update your duty-calculation worksheets and ACE entry data to reflect the correct additional duty rate as of the modification's effective date.
• If your company exports to or imports from Canada and has views on foreign trade barriers, review the USTR comment notice for the 2027 NTE Report and assess whether a submission is warranted before the comment deadline stated in that notice.
