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.
Listing and threshold

|---|---|
| Regime | China Inventory of Existing Chemical Substances (IECSC), administered by the Ministry of Ecology and Environment (MEE) |

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

Glossary
IECSC, Inventory of Existing Chemical Substances in China
The Chinese national chemical inventory listing substances legally manufactured, imported, used, or sold in China before 2003. A substance not on IECSC requires a New Chemical Substance Notification (NCSN) under MEE Order 12 before it can be manufactured or imported into China. Functionally similar to TSCA in the US and REACH in the EU but with distinct procedural requirements.
