From the buying desk

Bulk metal commodity. SHG (Special High Grade) at 99.995% min Zn is the LME-traded standard. Ships in ingots, jumbo, or slabs depending on downstream use. China is one of the largest producers but typically self-consumes most output for galvanising and die-casting.

Import Card

Before you order zinc from China, see its register listing, the duty, anti dumping cases and a supplier check on one card, each with its source and date.

Typical Chinese supplier geography

Major Chinese capacity sits in Yunnan, Hunan, Inner Mongolia. 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 Zinc 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.
