U.S. imports of copper mattes & cement copper (precipitated copper) (HS 740100) totaled $49K in April 2026, traded with 3 countries.
Copper Mattes & Cement Copper (Precipitated Copper) imports of $49K in April 2026 ran 145% above the year-to-date monthly average of $20K.
Last updated: April 2026 dataCopper mattes and cement copper represent the earliest-stage intermediate forms in the copper smelting and hydrometallurgical recovery chains, respectively — copper mattes (7401000010) are the sulfide-rich furnace output from primary smelting, while cement copper (7401000050) is recovered by precipitation from leach solutions and typically carries lower purity. Belgium and Czech Republic are the leading US import sources for this heading, reflecting Europe's role in secondary and recycled copper processing. Because these materials are upstream intermediates rather than refined metal, they are primarily purchased by copper refineries and smelters rather than end-use fabricators.

Copper matte (7401000010) is a sulfide-based intermediate produced by pyrometallurgical smelting and contains copper, iron, and sulfur in varying proportions. Cement copper (7401000050) is produced hydrometallurgically — copper ions in solution are precipitated onto scrap iron — and is typically lower in purity and more irregular in form. The distinction matters for classification because CBP may request mill certificates or assay reports to confirm the production method and copper content.
As of current schedules, copper mattes and cement copper under HTS 7401 are not subject to Section 232 or Section 301 tariffs, but importers should verify the current status with CBP or a licensed customs broker, as trade-remedy coverage can change. The leading supply from Belgium and Canada under USMCA may also affect duty treatment for Canadian-origin shipments.
