From the buying desk

Class 5.1 oxidiser. Most global supply is from chlor-alkali producers; China contributes a smaller share than North America (Erco, Olin) or South Africa. Ships in HDPE drums or 1 t bags. Pulp-mill chlorine dioxide (ClO2) generation is the largest global sink.

Typical Chinese supplier geography

Major Chinese capacity sits in Shandong, Sichuan. 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 Sodium chlorate 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 plus an MSA China DG packing certificate. For Incoterms reference see FOB, CIF, and CFR.
