Section 232 tariffs on copper
In effect (status checked Oct 16, 2026, the last day we checked the Federal Register for later documents).
Proclamation 11032 (91 FR 34085): “I determine that it is necessary and appropriate to modify, as further described below, the tariff regimes for metal products imposed in Proclamation 9704, as amended, Proclamation 9705, as amended, and Proclamation 10962, as amended.”
Proclamation 10962 imposed a 50% Section 232 tariff on semi-finished copper products and intensive copper derivative products from August 1, 2025, applied only to their copper content. From April 6, 2026, Proclamation 11021 applies the duty to the full customs value: 50% for most copper articles listed in Annex I-A and 25% for copper articles listed in Annex I-B. A 10% rate applies to Annex I-A derivative articles and Annex I-B articles whose copper content was smelted and cast in the United States. Proclamation 11021 also ended the copper derivative inclusion process. Proclamation 11032 set the U.S.-metal threshold at 85% by weight and modified the annex product lists from June 8, 2026. Civil aircraft and parts from the EU, Japan, South Korea and Taiwan, and Taiwan auto parts, are not subject to the copper duty headings under partner notices.
