Three-day suspension shifts effective date of new additional duties on Canadian alcohol, dairy, and motor vehicle imports to Aug. 22, 2026.

1. What changed

The President issued a proclamation temporarily suspending, for three days, the additional ad valorem duties previously imposed on certain imports from Canada under Proclamations 11046 (alcoholic beverages), 11047 (dairy), and 11048 (motor vehicles). The only concrete change in this proclamation is a shift in the effective date of those additional duties from August 19, 2026, to 12:01 a.m. eastern time on August 22, 2026. The proclamation also directs U.S. Customs and Border Protection (CBP) and other agencies to suspend collection of the additional duties as needed to implement this date change and to process any required duty refunds.

2. Affected products

The proclamation itself does not list specific HTS codes, but it explicitly references the product scopes defined in:

• Proclamation 11046: certain imports of Canada related to alcoholic beverages.
• Proclamation 11047: certain imports of Canada related to dairy, specifically tied to Canada’s tariff-rate quota allocation measures on U.S. cheeses of all types.
• Proclamation 11048: certain imports of Canada related to motor vehicles, including autos and auto parts.

Therefore, affected products are:

• Canadian-origin alcoholic beverages covered by Annex II of Proclamation 11046.
• Canadian-origin dairy products (notably cheeses) covered by Annex II of Proclamation 11047.
• Canadian-origin motor vehicles and auto parts covered by Annex II of Proclamation 11048.

The precise HTSUS subheadings and product descriptions are contained in the Annex II of each of those proclamations and may be further refined by any subsequent HTSUS modifications published by CBP in the Federal Register.

3. Rate changes

This proclamation does not change the level (percentage) of the additional ad valorem duties; it only suspends their application for three days by moving the effective date.

Key points:

• Under section 338 of the Tariff Act of 1930, the President had imposed additional ad valorem duties (not to exceed 50 percent ad valorem) on certain Canadian-origin products in Proclamations 11046, 11047, and 11048.
• Those additional duties were originally scheduled to take effect on August 19, 2026.
• This new proclamation does not alter the duty percentages or structure; it only delays the start date to August 22, 2026.

Because the exact duty rates (e.g., 10%, 25%, etc.) are not specified in this text, importers must refer to the Annex II of Proclamations 11046, 11047, and 11048 and any related HTSUS notes for the specific additional duty rates applicable to each HTS line.

4. Dates

• Original effective date of additional duties (per Proclamations 11046, 11047, 11048): August 19, 2026.
• New effective date of additional duties (per this proclamation): 12:01 a.m. eastern time on August 22, 2026.
• Suspension period: The additional duties are effectively suspended for the three-day period from 12:01 a.m. eastern time on August 19, 2026, through 11:59 p.m. eastern time on August 21, 2026.
• Duration of this proclamation’s change: The proclamation does not specify an expiration date for the duties themselves; it only adjusts the start date. The underlying measures in Proclamations 11046, 11047, and 11048 remain in place as of August 22, 2026, unless later modified or revoked.

5. Required actions for importers, brokers, and compliance teams

a) Entry timing and planning

• For covered Canadian-origin alcoholic beverages, dairy products (including cheeses), and motor vehicles/auto parts, entries made:
• On or before 11:59 p.m. eastern time on August 21, 2026: should NOT be subject to the new additional ad valorem duties imposed under Proclamations 11046, 11047, and 11048.
• On or after 12:01 a.m. eastern time on August 22, 2026: WILL be subject to the additional ad valorem duties, at the rates and on the HTS lines specified in the relevant annexes.
• Importers should review shipment schedules and, where commercially and operationally feasible, consider whether to time entries of affected Canadian-origin goods before August 22, 2026, to avoid the additional duties.

b) HTS classification and flagging

• Confirm whether any imported Canadian-origin products fall within the scope of Annex II of Proclamations 11046, 11047, and 11048.
• Ensure that internal classification databases and broker instructions clearly flag the affected HTS lines as subject to additional duties starting August 22, 2026.
• Monitor the Federal Register for any CBP notice modifying the HTSUS to implement this proclamation, including any new or revised Chapter 99 provisions or notes that may be used to assess the additional duties.

c) Entry filing and duty calculation

• For entries of covered Canadian-origin goods on or after August 22, 2026:
• Ensure that the correct additional ad valorem duty is applied in addition to the normal MFN/USMCA rate, as specified in the relevant proclamations and HTSUS notes.
• Coordinate with customs brokers to confirm that ACE programming and broker systems reflect the new effective date and any associated Chapter 99 or special program indicators.
• For entries filed between August 19 and August 21, 2026, where additional duties may have been preliminarily assessed based on the original effective date:
• Review CBP guidance and entry summaries to identify any overpayments.
• Work with brokers to file post-summary corrections (PSCs) or protests as needed, consistent with CBP’s standard refund procedures.

d) Refunds

• The proclamation explicitly states that, to the extent implementation requires a refund of duties collected, refunds shall be processed pursuant to applicable law and CBP’s standard procedures.
• Compliance teams should:
• Identify entries of covered Canadian-origin goods where additional duties were collected for import dates prior to 12:01 a.m. eastern time on August 22, 2026.
• Coordinate with brokers to ensure timely filing of PSCs or protests to secure refunds, following CBP’s normal timelines and documentation requirements.

e) Contracting and pricing

• Review contracts with Canadian suppliers and U.S. customers for affected products to ensure that pricing and duty responsibility clauses reflect the new effective date.
• Consider whether the three-day suspension affects any duty-inclusive pricing, delivered duty paid (DDP) terms, or cost pass-through arrangements.

f) Monitoring and future changes

• The proclamation notes that Canada has expressed a commitment to remove the discriminatory measures and that negotiations are ongoing. This suggests the possibility of further changes, including potential modification, suspension, or revocation of the additional duties.
• Compliance teams should:
• Monitor future White House proclamations, USTR announcements, and Federal Register notices for any updates to the measures under section 338.
• Track any HTSUS amendments issued by CBP to implement this proclamation and any subsequent changes.

6. References and where to find details

For full product coverage, HTS lines, and duty rates, consult:

• Proclamation 11046 (Imposing Additional Duties to Offset Canadian Discrimination Against the Commerce of the United States With Respect to Alcoholic Beverages), including Annex II.
• Proclamation 11047 (Imposing Additional Duties to Offset Canadian Discrimination Against the Commerce of the United States With Respect to Dairy), including Annex II.
• Proclamation 11048 (Imposing Additional Duties to Offset Canadian Discrimination Against the Commerce of the United States With Respect to Motor Vehicles), including Annex II.

These documents, along with the current proclamation, are typically available on:

• The White House website (Presidential Actions / Proclamations section):

https://www.whitehouse.gov/briefing-room/presidential-actions/

• The Federal Register (search by proclamation number or title):

https://www.federalregister.gov/

CBP will publish any necessary HTSUS modifications in the Federal Register. Importers should review those notices for:

• Specific HTS subheadings covered.
• Any new or amended Chapter 99 provisions.
• Implementation instructions for ACE and entry filing.

7. HTS metadata

The proclamation does not explicitly list any HTS headings or codes. All HTS details are contained in the annexes to Proclamations 11046, 11047, and 11048 and any subsequent HTSUS amendments published by CBP. As such, no specific HTS codes can be extracted directly from this text.

Compliance teams should obtain the annexes and HTSUS updates to build or update internal HTS lists for:

• Canadian-origin alcoholic beverages subject to the additional duties.
• Canadian-origin dairy products (including cheeses) subject to the additional duties.
• Canadian-origin motor vehicles and auto parts subject to the additional duties.

8. Key takeaways

• The additional ad valorem duties on certain Canadian alcoholic beverages, dairy products, and motor vehicles/auto parts are delayed and now start at 12:01 a.m. eastern time on August 22, 2026.
• Entries of covered Canadian-origin goods before that time should not be assessed the new additional duties, and any such duties collected may be refundable.
• Importers and brokers must adjust entry timing, duty calculations, and internal systems to reflect the new effective date and monitor for HTSUS modifications and further policy changes as negotiations with Canada proceed.
