President Trump issued a Proclamation this afternoon, July 30, stating that all imports of semi-finished copper products and intensive copper derivative products will be subject to a 50% tariff, effective at 12:01 a.m. ET on August 1, 2025.

This tariff shall be effective with respect to goods entered for consumption, or withdrawn from warehouse for consumption, on or after 12:01 a.m. ET on August 1, 2025, and shall continue in effect, unless such action is expressly reduced, modified, or terminated, according to the Proclamation.

“This tariff is in addition to any other duties, fees, exactions, and charges applicable to such imported semi-finished copper products and intensive copper derivative products,” the Proclamation said.

Full details of the White House Proclamation are available here.  Here is the issued Fact Sheet.

Copper Tariff Rate:

• 50% additional ad valorem duties (which are in addition to any other duties, fees, etc., applicable to such imported goods).

Scope Expansion:

• The Commerce Department will establish a process to add products to the scope of the tariffs within 90 days (Oct. 28). The process will be similar to the process currently in place to add products to the scope of coverage for aluminum and steel products.

Application of the 50% Tariff and Stacking:

• The 50% tariff will be assessed on the value of the copper content in a product.
• The non-copper content of the product will be subject to IEEPA reciprocal tariffs or other duties such as the IEEPA border/fentanyl tariffs on Mexican and Canadian products, or the IEEPA Fentanyl tariff on China, or the Section 301 tariffs on China.

Exclusions:

• The 50% tariff shall not apply to products subject to the autos/parts Section 232 tariffs.
• According to the Fact Sheet, Copper input materials (ores, concentrates, mattes, cathodes, and anodes) and copper scrap are not subject to 232 or reciprocal tariffs, but absent the Annex listing the specific HTS codes involved, we are unable to confirm at this time.

FTZ Goods:

• Products admitted to an FTZ after 12:01 am ET on Aug. 1, must be admitted in Privileged Foreign Status.
• Goods eligible for admission to an FTZ under domestic status are exempt from the tariffs.

Modifications and Expansion:

• The Commerce Department will monitor imports to determine if modifications are required.
• By June 30, 2026, the Commerce Department report on domestic copper markets, including refining capacity and the market for refined copper in the U.S., is to be provided to the President, which could support the President imposing on refined copper a 15% tariff effective Jan. 1, 2027, and 30% tariff on Jan. 1, 2028, if warranted. (note: the Fact Sheet references potential increased tariffs on such goods up to 40% in 2029, but the Pres. Proc. does not reference such dates or additional tariff amounts).

Duty Drawback:

• Duty Drawback is prohibited.
