Typical Chinese supplier geography

Major Chinese capacity sits in Yunnan, Hunan, Hebei. 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 Calcium hydroxide 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.
