BY THE PRESIDENT OF THE UNITED STATES OF AMERICA
A PROCLAMATION
1. In Proclamation 11048 dated July 20, 2026, additional duties were imposed to counter Canadian discrimination against U.S. commerce concerning motor vehicles. It was determined that Canada’s motor vehicle tariff system unfairly disadvantaged U.S. commerce compared to other countries. This unreasonable imposition was not equally enforced on similar articles from every foreign country, thereby burdening U.S. commerce. To counteract this, additional ad valorem duties were introduced under section 338 of the Tariff Act of 1930, effective August 19, 2026, targeting specific Canadian products.
2. On August 18, 2026, through Proclamation 11056, the effective date of these additional duties was temporarily suspended for three days after Canada committed to addressing the discriminatory practices highlighted in Proclamation 11048.
3. However, on August 21, 2026, Canada failed to honor its commitment, halting good faith negotiations and maintaining the discriminatory and unequal imposition addressed in Proclamation 11048.
4. Consequently, at 12:01 a.m. eastern time on August 22, 2026, the temporary suspension from Proclamation 11056 expired, and the additional ad valorem duties from Proclamation 11048 were enforced.
5. I have received feedback from senior executive branch officials regarding the circumstances of Proclamation 11048 and the impact of the additional duties. They affirmed that while these duties counterbalance the burden on U.S. commerce, modifying the range of products subject to these duties could further offset the disadvantages and serve the public interest. They recommend that such modifications align with U.S. interests and public welfare.
6. After reviewing the provided insights and other pertinent information, I have concluded that the public interest necessitates modifying the scope of products subject to the additional ad valorem duties in Proclamation 11048.
7. The changes outlined in this proclamation will mitigate the disadvantages faced by U.S. commerce, align with both public and national interests, and enhance public welfare.
8. Section 338 empowers the President to address burdens on U.S. commerce resulting from foreign discrimination by specifying additional duties up to 50 percent ad valorem, effective no sooner than 30 days after such a proclamation. This section also allows the President to modify any proclamation under it or exclude importation of certain products if the foreign discrimination persists, ensuring alignment with U.S. interests.
9. Section 604 of the Trade Act of 1974 allows the President to incorporate statutory changes affecting import treatment into the Harmonized Tariff Schedule of the United States, including altering, continuing, or imposing any duty rate or import restriction.
NOW, THEREFORE, I, DONALD J. TRUMP, President of the United States of America, by the authority vested in me by the Constitution and the laws of the United States, including section 338, section 301 of title 3, United States Code, and section 604, proclaim as follows:
(1) Except as otherwise specified, certain Canadian products listed in Annex I, Part A, imported into the U.S. will face an additional ad valorem duty of 50 percent as per Proclamation 11048. Conversely, products in Annex I, Part B will no longer be subject to this duty. These duties, as amended, will be in addition to those under section 232 of the Trade Expansion Act of 1962. These changes take effect for goods entered for consumption or withdrawn from warehouse for consumption on or after 12:01 a.m. eastern time on September 15, 2026.
(2) The HTSUS is amended as detailed in Annex II of this proclamation, effective for goods entered for consumption or withdrawn from warehouse for consumption on or after 12:01 a.m. eastern time on September 15, 2026, and will remain in effect unless expressly altered or terminated.
(3) Heads of all executive departments and agencies are authorized to take necessary measures to implement this proclamation within their authority. They may redelegate this authority as allowed by law, including section 301 of title 3, United States Code.
(4) The Commissioner of U.S. Customs and Border Protection (CBP), consulting with the Secretary of the Treasury, Secretary of Commerce, and the United States Trade Representative, is empowered to issue necessary rules, regulations, and guidance to implement this proclamation and administer its provisions.
(5) The Commissioner of CBP, in consultation with relevant senior officials, will determine if further modifications to the HTSUS are needed to effectuate this proclamation and will make such modifications through notice in the Federal Register, including any technical or ministerial corrections to the annexes.
(6) For any rule or regulation made by the Commissioner of CBP to implement this proclamation, approval must be obtained from the President or the United States Trade Representative, with the latter delegated approval authority under 19 U.S.C. 1338(h).
(7) Any previous proclamations or Executive Orders inconsistent with this proclamation are superseded to the extent of the inconsistency.
(8) If any part of this proclamation or its application is declared invalid, the remaining provisions and their application to other individuals or circumstances remain unaffected.
IN WITNESS WHEREOF, I have hereunto set my hand this eighth day of September, in the year of our Lord two thousand twenty-six, and of the Independence of the United States of America the two hundred and fifty-first.

ANNEX II
DONALD J. TRUMP
