Copper tariff impact page for importers: common HS areas, base duty, April 2026 Section 232 proclamation, and calculator workflow.
Copper tariff exposure depends on the copper product form, HTS classification, origin, and any active policy action or trade remedy. Importers should check the base HTS rate first, then review the April 2026 Section 232 proclamation and subsequent amendments alongside, AD/CVD, and Federal Register notices before adding an extra tariff layer.
Copper ores, wire, tubes, and articles can classify differently.
Use Federal Register and CBP sources for changes.
Keep policy-risk rate separate from base duty.
The April 2026 proclamation changed covered steel, aluminum and copper treatment from April 6, including full-customs-value assessment for covered products and different annex-based rates. Product scope, metal origin, exceptions and subsequent amendments must be checked before quoting a shipment. Copper is already addressed in this proclamation; it is not merely a possible future investigation.
Copper raw materials, refined copper, wire, tubes, fittings, and finished articles can fall under different headings. Classification is the first control point.
Attach the HTS lookup, product specs, origin documents, any policy notice reviewed, and the calculation trace showing base duty separate from modeled additional duty.

Check current official notices and your specific HTS code. Copper tariff risk depends on product form, origin, and policy action.
Copper and articles of copper are generally in Chapter 74, but finished goods may classify elsewhere.
Use the calculator with the base HTS rate, then add a clearly labeled modeled policy layer if source review supports it.
