Phosphorus (red)

红磷

Class 4.1 flammable solid. White phosphorus (UN 1381) is much more hazardous and rarely traded. Red phosphorus is the export form. Ships in HDPE drums under inert atmosphere. Major Chinese supply from Yunnan, Guizhou. Carrier-side scrutiny on Class 4 cargo is meaningful.

Typical Chinese supplier geography

Major Chinese capacity sits in Yunnan, Guizhou, 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 Phosphorus (red) 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.
