CAS reference

Formaldehyde

甲醛

EU CMR Cat 1B carcinogen; US TSCA Section 6 active risk evaluation. Trade is overwhelmingly as 37 percent aqueous formalin solution stabilised with methanol. Most downstream use (urea-formaldehyde, melamine-formaldehyde, phenol-formaldehyde resin) consumes the formaldehyde at the producer site rather than shipping it.

Typical Chinese supplier geography

Major Chinese capacity sits in Shandong, Jiangsu, Henan. 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 Formaldehyde 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.
