Adjustments to Section 232 Metals Tariff Start June 8

2 June 2026 4 MINS. Read USA

On June 1, 2026, U.S. President Trump issued a proclamation, Further Adjusting the Tariff Regimes for Imports of Aluminum, Steel, and Copper into the United States.

The proclamation makes changes to the Section 232 metals tariffs starting June 8, 2026. A key modification provides temporary duty relief for a short list of Harmonized Tariff Schedule (HTS) numbers in Annex I-C, including agricultural equipment and mobile industrial equipment, such as bulldozers and forklifts. The proclamation also encourages foreign companies to use more U.S. steel and aluminum by providing a 10% duty rate if their capital equipment includes at least 85% U.S. ‘melted and poured’ or ‘smelted and cast’ steel or aluminum by weight. Additionally, new HTSUS are being added to the tariff, including “other photographic plates and film classified in 3701.30.00” and “steel shelving, racks, and parts classified in 9403,” which will be subject to the tariffs.

Annex I-C

Temporary Duty Rate Adjustments Effective June 8, 2026 – December 31, 2027

Effective with respect to goods entered for consumption, or withdrawn from warehouse for consumption, on or after 12:01 a.m. eastern daylight time on June 8, 2026, until 11:59 p.m. eastern standard time on December 31, 2027, the applicable additional ad valorem rate of duty imposed pursuant to section 232 under Proclamation 9704, as amended, and Proclamation 9705, as amended, for all aluminum and steel articles listed in Annex I-C to this proclamation shall be:

(a) 25 percent, unless a lower rate of duty applies pursuant to clause (2)(b), (2)(c), or (2)(d) of this proclamation;

(b) For products of Argentina, Ecuador, El Salvador, Guatemala, Japan, the Republic of Korea, Liechtenstein, Switzerland, Taiwan, the United Kingdom, or a member nation of the European Union, the rate of duty shall be determined by the product’s current ad valorem (or ad valorem equivalent) rate of duty under Column 1 of the HTSUS (Column 1 Duty Rate). For products of these jurisdictions with a Column 1 Duty Rate that is less than 15 percent, the sum of the Column 1 Duty Rate and the additional section 232 ad valorem rate of duty pursuant to this clause, shall be 15 percent. For products of these jurisdictions with a Column 1 Duty Rate that is at least 15 percent, the additional section 232 ad valorem rate of duty imposed pursuant to this clause shall be zero percent;

(c) 10 percent, determined based on the product’s current ad valorem (or ad valorem equivalent) Column 1 Duty Rate in the same manner outlined in clause (2)(b) of this proclamation, for derivative articles the aluminum content of which is composed entirely of aluminum that was smelted and cast in the United States, or the steel content of which is composed entirely of steel that was melted and poured in the United States; and

(d) For products of Canada and Mexico that qualify for preferential tariff treatment under the United States–Mexico–Canada Agreement, a duty of 25 percent shall apply only to the non-U.S. content of the product.

For purposes of this clause, “non-U.S. content” means the total value of the product minus the value attributable to parts produced in the United States.
Notwithstanding the foregoing, the total effective duty on the imported product assessed under this subclause shall not be less than 15 percent ad valorem, as detailed in Annex IV of this proclamation.
The Secretary shall issue guidance to U.S. Customs and Border Protection (CBP) regarding the assessment of “U.S. content” for purposes of this clause.
If CBP determines that an importer has engaged in fraud or has deliberately misled the United States Government regarding the United States content of an imported product, CBP shall impose penalties to the extent permitted by law.

Starting January 1, 2028

Effective with respect to goods entered for consumption or withdrawn from warehouse for consumption on or after 12:01 a.m. eastern standard time on January 1, 2028, the applicable additional ad valorem rate of duty imposed under Proclamation 9704, as amended; Proclamation 9705, as amended; and Proclamation 10962, as amended, for imports of products listed in Annex I-C to this proclamation shall be the rates set out in clause (3) of Proclamation 11021.

If a product is subject to multiple rates of duty under clause (2) of this proclamation, the lowest applicable rate of duty shall apply.

Annex IV Modification – 85% U.S. Aluminum, Steel, Copper Rule

For purposes of this proclamation and Proclamation 11021, as set forth in Annex IV to this proclamation, a product’s metal content shall be deemed composed entirely of aluminum that was smelted and cast in the United States, of steel that was melted and poured in the United States, or of copper that was smelted and cast in the United States, if such aluminum, steel, and copper account for at least 85 percent of weight of the aluminum, steel, and copper of the product.
