Last updated: April 2026 dataCopper concentrates — the flotation-processed product of sulfide copper mining — are a foundational input for smelters and refiners, and the US tariff schedule uniquely apportions value across multiple metal contents within a single shipment: copper content (2603000010), precious metal content (2603000015), zinc content (2603000030), other metal content (2603000035), silver content (2603000040), and gold content (2603000050). Chile, the world's largest copper producer, leads US imports under this heading. The multi-line structure reflects the commercial reality that copper concentrates carry payable credits for co-products such as gold and silver, which must be declared separately for customs valuation purposes.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
US customs requires that the value of each payable metal in a copper concentrate be declared under its own 10-digit line — copper content, gold content, silver content, zinc content, and so on — because each may carry a different duty rate and because accurate valuation of co-product credits is required. Importers typically work with the smelter's provisional assay and the applicable treatment-charge/refining-charge terms to allocate value across lines 2603000010 through 2603000050.
Standard documentation includes a provisional or final assay certificate from an accredited laboratory, the offtake or purchase contract specifying payable metal percentages and price participation factors, and a commercial invoice that allocates value by metal content. CBP may request additional assay verification, and discrepancies between provisional and final assays often require post-entry amendments.
