Oxygen (O2) under IECSC

O2 · 氧气

Status: Listed. Oxygen is on the IECSC public portion. **On China's Catalog of Hazardous Chemicals at industrial-grade purity** as an oxidizer (verify the specific entry against the most recent MEE Catalog of Hazardous Chemicals before relying); GB 6944 Class 2.2 + 5.1 transport status applies. NOT on Highly Toxic Chemicals Catalog. NOT on Easily-Made Drugs Catalog. **China VAT export rebate** for oxygen (HS 280440) per current inorganic chemicals chapter rebate schedule (verify the rate against the most recent MOF / GACC rebate notice before invoicing). Major Chinese industrial-O2 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.

Oxygen is comfortably IECSC-listed but **on Catalog of Hazardous Chemicals at industrial-grade purity as oxidizer** (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). Industrial O2 is captive ASU.

Import Card

Before you order oxygen (O2) 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 Oxygen (O2) (CAS 7782-44-7), O2
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 required for compressed / refrigerated-liquefied transport (verify against the most recent MEE Catalog before relying)

Classifications under this regime

  • On Catalog of Hazardous Chemicals at industrial-grade purity as oxidizer (verify the specific entry against the most recent MEE Catalog before relying)
  • GB 6944-2012 transport: Class 2.2 + subsidiary 5.1 (compressed UN 1072 or refrigerated liquefied UN 1073)
  • NOT on Highly Toxic Chemicals Catalog
  • NOT on Easily-Made Drugs Catalog
  • GB/T 17519-2013 Chinese SDS standard
  • GACC HS code: 280440
  • **Pharma-grade compliance with Chinese Pharmacopoeia (ChP)** where placed as medical-grade O2 (verify monograph reference against the most recent ChP edition before relying)

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 inorganic chemicals chapter schedule (verify against the most recent MOF / GACC rebate notice before invoicing)
  • GB/T 17519 Chinese SDS required (Ox. Gas 1 + Press. Gas + fire-acceleration handling notes)
  • GB 6944 Class 2.2 + 5.1 transport classification applies

Importer obligations

For Chinese-origin industrial oxygen, no IECSC obligation falls on the foreign importer (O2 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 280440
  • GHS Chinese SDS per GB/T 17519
  • Hazardous Chemicals Operation Permit at producer + distributor sites
  • GB 6944-2012 Class 2.2 + 5.1 transport documentation
  • Pharma-grade ChP certification where applicable

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 as oxidizer (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
  • Major Chinese sources (captive ASU): Sinopec + CNPC + Baowu Steel + HBIS Group + Hangzhou Hangyang + Yingde Gases + Linde China (verify each producer-site pair)
  • **Steel-mill BOF feedstock + medical-O2 + oxy-fuel welding + pulp bleaching + semiconductor + chemical synthesis captive feedstock downstream chains** dominate Chinese consumption
