Nitrogen (N2) under IECSC
N2 · 氮气
Status: Listed. Nitrogen is on the IECSC public portion. **NOT on China's Catalog of Hazardous Chemicals at industrial-grade purity** (verify against the most recent MEE Catalog of Hazardous Chemicals before relying; compressed-gas / refrigerated-liquefied transport handling applies). NOT on Highly Toxic Chemicals Catalog. NOT on Easily-Made Drugs Catalog. **China VAT export rebate** for nitrogen (HS 280430) per current inorganic chemicals chapter rebate schedule (verify the rate against the most recent MOF / GACC rebate notice before invoicing). Major Chinese industrial-N2 sources tied to ASU on-site supply at Sinopec + CNPC petrochemical complexes, Baowu Steel + HBIS Group steel mills, Hangzhou Hangyang industrial-gas company, Yingde Gases (formerly Praxair China JV), Linde China; verify each producer-site pair against the producer's public website before relying on a specific plant.
Nitrogen is comfortably IECSC-listed; typically NOT on Catalog of Hazardous Chemicals at industrial grade. NOT on Highly Toxic, NOT on Easily-Made Drugs. **China VAT export rebate** rate per current schedule (verify before invoicing). Industrial N2 is captive ASU.
Import Card
Before you order nitrogen (N2) from China, see its register listing, the duty, anti dumping cases and a supplier check on one card, each with its source and date.
Listing and threshold
| Substance | Nitrogen (N2) (CAS 7727-37-9), N2 |
|---|---|
| Regime | China Inventory of Existing Chemical Substances (IECSC), administered by the Ministry of Ecology and Environment (MEE) |
| Jurisdiction | People's Republic of China |
| Status | Listed |
| Tonnage threshold | No new-substance threshold. Hazardous Chemicals Operation Permit may apply for compressed / refrigerated-liquefied transport (verify against the most recent MEE Catalog before relying) |
Classifications under this regime
- NOT typically on Catalog of Hazardous Chemicals at industrial-grade purity (verify against the most recent MEE Catalog before relying)
- NOT on Highly Toxic Chemicals Catalog
- NOT on Easily-Made Drugs Catalog
- GB/T 17519-2013 Chinese SDS standard
- GACC HS code: 280430
- GB 6944-2012 transport: Class 2.2 (compressed UN 1066 or refrigerated liquefied UN 1977)
- **Pharma-grade compliance with Chinese Pharmacopoeia (ChP)** where placed as medical-grade N2 (verify monograph reference against the most recent ChP edition before relying)
Restrictions and conditions of use
- Hazardous Chemicals Operation Permit may apply for compressed / refrigerated-liquefied transport (verify against the most recent MEE Catalog before relying)
- **China VAT export rebate** rate per current inorganic chemicals chapter schedule (verify against the most recent MOF / GACC rebate notice before invoicing)
- GB/T 17519 Chinese SDS required
Importer obligations
For Chinese-origin industrial nitrogen, no IECSC obligation falls on the foreign importer (N2 is rarely cross-border traded at scale due to low value-density and regional captive ASU structure). Major Chinese sources: Sinopec + CNPC ASUs, Baowu Steel + HBIS Group, Hangzhou Hangyang, Yingde Gases, Linde China.
Required documents
- GACC export declaration HS 280430
- GHS Chinese SDS per GB/T 17519
- Pharma-grade ChP certification where applicable
- GB 6944-2012 Class 2.2 transport documentation
Common compliance traps
The pitfalls that have bitten importers on this lane in the past. None of these is theoretical.
- Catalog of Hazardous Chemicals status (verify against the most recent MEE Catalog before relying)
- **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
- Major Chinese sources (captive ASU): Sinopec + CNPC + Baowu Steel + HBIS Group + Hangzhou Hangyang + Yingde Gases + Linde China (verify each producer-site pair)
- **Ammonia synthesis feedstock (Haber-Bosch) + food-MAP + electronics-blanket + tire inflation + tank-blanketing downstream chains**
- N2 not typically cross-border traded at scale (low value-density + regional captive ASU)

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.
