Copper Waste and Scrap

CBP values copper scrap based on the transaction value declared on the commercial invoice, which should reflect the specific scrap grade (e.g., No. 1 Bare Bright, No. 2 Copper, Birch/Cliff). Misrepresenting a lower grade as a higher grade to inflate value — or understating value to reduce duties — can trigger penalties. Importers should ensure the grade description on the invoice matches the Institute of Scrap Recycling Industries (ISRI) specification or an equivalent recognized grading standard.

The US has not ratified the Basel Convention, so Basel controls do not directly restrict US import transactions. However, exporting countries that are Basel parties may impose export controls or prior-informed-consent requirements on shipments of contaminated or mixed copper scrap leaving their territory. US importers sourcing from non-OECD Basel parties should confirm with their supplier that all required export authorizations have been obtained to avoid shipment delays or seizure at the origin port.
