Copper

Bulk metal commodity. Cathode at 99.99% min Cu (LME Grade A) is the exchange-traded standard. Ships in cathodes, wire rod, or billets. Chinese refining capacity (Jiangxi Copper, Tongling Nonferrous, Yunnan Copper) is the largest globally. Most refined copper from China is consumed domestically.

Typical Chinese supplier geography

Major Chinese capacity sits in Jiangxi, Anhui, Yunnan. Coastal producers (Shandong, Jiangsu, Zhejiang) typically dominate export volume because of port access; inland producers (Inner Mongolia, Xinjiang, Shaanxi) compete on raw-material cost but add inland-rail or trucking cost to reach the coast.

Sourcing documentation chain

Every shipment of Copper from China should include a per-batch COA, a current SDS per GB/T 17519 on the China side and the destination jurisdiction's standard on the import side, a packing list, a bill of lading, and a certificate of origin. For Incoterms reference see FOB, CIF, and CFR.
