n-Hexane under IECSC

C6H14 · 正己烷

Status: Listed. n-Hexane is on the IECSC public portion. **On China's Catalog of Hazardous Chemicals at industrial-grade purity (verify the specific entry against the most recent MEE Catalog of Hazardous Chemicals before relying); GB 6944 Class 3 flammable liquid transport status applies.** NOT on Highly Toxic Chemicals Catalog. NOT on Easily-Made Drugs Catalog. **China VAT export rebate** for n-hexane (HS 290110) per current organic chemicals chapter rebate schedule (verify the rate against the most recent MOF / GACC rebate notice before invoicing). Major Chinese producers (typically integrated with refinery / petrochemical complexes): Sinopec Maoming, Sinopec Zhenhai, Sinopec Tianjin, CNPC PetroChina Lanzhou, Wanhua Chemical Yantai, Shandong Dongming Petrochemical (verify each producer-site pair against the producer's public website before relying on a specific plant). **Hazardous Chemicals Operation Permit required** at producer plus distributor sites. **China occupational exposure limit for n-hexane per GBZ 2.1-2019 is 100 mg/m3 8-hr TWA-PC (PC-TWA) plus 180 mg/m3 STEL-PC (PC-STEL) reflecting peripheral neuropathy concern (verify the current GBZ-listed limit for n-hexane against the GBZ 2.1 schedule before relying)**.

n-Hexane is comfortably IECSC-listed but **on Catalog of Hazardous Chemicals at industrial-grade purity** (Hazardous Chemicals Operation Permit required at producer + distributor sites). NOT on Highly Toxic, NOT on Easily-Made Drugs. **China VAT export rebate** rate per current schedule (verify before invoicing). **GBZ 2.1-2019 PC-TWA 100 mg/m3 reflects peripheral neuropathy concern**. IARC Group 3.

Classifications under this regime

  • On Catalog of Hazardous Chemicals at industrial-grade purity (verify the specific entry against the most recent MEE Catalog before relying)
  • GB 6944-2012 transport: Class 3 flammable liquid (UN 1208 PG II)
  • NOT on Highly Toxic Chemicals Catalog
  • NOT on Easily-Made Drugs Catalog
  • GB/T 17519-2013 Chinese SDS standard
  • GACC HS code: 290110
  • **China occupational exposure limit per GBZ 2.1-2019: 100 mg/m3 PC-TWA + 180 mg/m3 PC-STEL (peripheral neuropathy concern)** (verify the current GBZ-listed limit against the GBZ 2.1 schedule before relying)
  • IARC Group 3 (not classifiable)

Restrictions and conditions of use

  • **Hazardous Chemicals Operation Permit required** at producer plus distributor sites (verify against the most recent MEE Catalog before relying)
  • **China VAT export rebate** rate per current organic chemicals chapter schedule (verify against the most recent MOF / GACC rebate notice before invoicing)
  • GB/T 17519 Chinese SDS required (Repr. 2 + STOT RE 2 peripheral neuropathy + Asp. Tox. 1 + Flam. Liq. 2 hazard profile)
  • GB 6944 Class 3 transport classification applies

Importer obligations

For Chinese-origin n-hexane exported abroad, no IECSC obligation falls on the foreign importer; however, the **export-side Hazardous Chemicals Operation Permit chain plus GB 6944 Class 3 transport** are the dominant compliance considerations. Major Chinese producers: Sinopec Maoming, Sinopec Zhenhai, Sinopec Tianjin, CNPC PetroChina Lanzhou, Wanhua Chemical Yantai, Shandong Dongming Petrochemical.

Required documents

  • GACC export declaration HS 290110
  • GHS Chinese SDS per GB/T 17519
  • Hazardous Chemicals Operation Permit at producer + distributor sites
  • GB 6944 Class 3 transport documentation

Common compliance traps

The pitfalls that have bitten importers on this lane in the past. None of these is theoretical.

  • On Catalog of Hazardous Chemicals at industrial-grade purity (verify against the most recent MEE Catalog before relying)
  • **Hazardous Chemicals Operation Permit required** at producer + distributor sites
  • **China VAT export rebate** rate (verify against the most recent MOF / GACC rebate notice before invoicing)
  • NOT on Highly Toxic, NOT on Easily-Made Drugs
  • **China GBZ 2.1-2019 PC-TWA 100 mg/m3 + PC-STEL 180 mg/m3 (peripheral neuropathy concern)**
  • IARC Group 3 (not classifiable)
  • Major Chinese producers (integrated with refinery): Sinopec Maoming + Zhenhai + Tianjin, CNPC Lanzhou, Wanhua Yantai, Shandong Dongming Petrochemical (verify each producer-site pair)
  • Production: light naphtha steam-cracker C6 fraction or refinery raffinate / hydrotreater stream; specialty-grade fractional distillation purification
  • **Edible oil extraction solvent (~50% of consumption, soybean + cottonseed + canola) plus printing inks plus adhesives plus polymerisation solvent (LDPE + PP) plus gasoline blending plus lab solvent downstream chains** dominate Chinese consumption
