Copper metal (Cu) under TSCA

Cu · 铜

Status: Active. Copper metal is on the TSCA Active Inventory. **NOT typically Cal Prop 65 listed at refined copper level** (verify against OEHHA https://oehha.ca.gov/proposition-65/proposition-65-list before relying; specific copper compounds such as copper(I) cyanide may have separate listings). **Multiple US AD/CVD investigations on Chinese-origin downstream copper PRODUCTS exist across copper foil + copper sheet / strip + copper tube + copper alloy + copper wire / cable cases; verify each case + current cash-deposit rate per producer at https://access.trade.gov/ before invoicing**; the cash-deposit rate at customs is the operative number. **Section 232 national security investigation on copper imports announced by Department of Commerce 25 February 2025 under Executive Order 14220** (verify current Section 232 status + any duty / quota outcome against https://www.commerce.gov/ + https://www.bis.doc.gov/ before invoicing).

Copper metal is TSCA-Active with **multiple US AD/CVD investigations on Chinese-origin downstream copper PRODUCTS (foil + sheet / strip + tube + alloy + wire / cable); verify each case + current cash-deposit rate per producer at access.trade.gov before invoicing**. **Section 232 national security investigation on copper imports announced 25 February 2025 under EO 14220** (verify outcome). OSHA PEL copper dust 1 mg/m3 + fume 0.1 mg/m3. **US is structurally a net-importer of refined copper; primary sources Chile + Peru + Mexico + Canada + domestic.** **AD/CVD on downstream products + Section 232 are the practical US-import compliance pivots.**

Importer obligations

TSCA Section 13 import certification (positive). **AD/CVD scope determination per Chinese-origin downstream copper product per case + per producer at https://access.trade.gov/.** **Section 232 monitoring on copper imports per Executive Order 14220 (announced 25 February 2025).** US is structurally a net-importer of refined copper; primary sources Chile (Codelco + BHP Escondida + Antofagasta + Anglo American), Peru (Freeport-McMoRan Cerro Verde + Southern Copper + Antamina), Mexico (Southern Copper Buenavista + Grupo Mexico), Canada (Glencore Sudbury ON + Lundin Mining), domestic (Freeport-McMoRan Morenci AZ + Rio Tinto Kennecott UT + Asarco). Major Chinese exporters (downstream products only, given Chinese cathode import dependency): Jiangxi Copper Corporation, Tongling Nonferrous Metals, Yunnan Copper, Daye Nonferrous.

Required documents

  • TSCA Section 13 import certification
  • CBP entry HS 7403 (refined copper cathode) / 7404 (waste + scrap) / 7407-7411 (downstream products)
  • SDS (Aquatic Acute 1 + Aquatic Chronic 1 in particulate / powder form)
  • **AD/CVD entry documentation CBP Form 7501 per Chinese-origin downstream copper product per case + per producer (verify per case at https://access.trade.gov/)**
  • **Section 232 import documentation per EO 14220 outcome where applicable**
  • EPA TRI reporting documentation for copper compounds where placed on US site at threshold
  • COMEX warehouse warrant where contract delivery

Common compliance traps

The pitfalls that have bitten importers on this lane in the past. None of these is theoretical.
