CAS reference

Benzene

苯

CMR Category 1A carcinogen. EU REACH Annex XVII restricts use as a solvent in mixtures. US TSCA Section 6 active risk evaluation. Ships in stainless ISO tanks; specialty handling requirements meaningful. Most downstream uses (styrene, cumene, cyclohexane) consume the benzene at the producer site rather than shipping it.

  • · Cyclohexane (nylon upstream)
  • · Aniline production

Typical Chinese supplier geography

Major Chinese capacity sits in Liaoning, Shandong, Jiangsu. 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 Benzene 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.
