Carbon dioxide (CO2) under IECSC

CO2 · 二氧化碳

Status: Listed. Carbon dioxide 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 is launching a national emissions trading scheme (China ETS) covering power-sector CO2 emissions since July 2021 with planned expansion to cement + steel + aluminium 2024-2025 (verify current China ETS scope against MEE / Ministry of Ecology and Environment announcements before relying)**. **China VAT export rebate** for carbon dioxide (HS 281121) per current inorganic chemicals chapter rebate schedule (verify the rate against the most recent MOF / GACC rebate notice before invoicing). Major Chinese industrial-CO2 sources tied to ammonia-plant + ethanol-fermentation + SMR captive supply: Sinopec + CNPC ammonia / SMR vents, Yara China ammonia plants, COFCO Biochemical ethanol-fermentation vents, Henan Jindian Chemical, Yingde Gases, Hangzhou Hangyang industrial-gas company (verify each producer-site pair against the producer's public website before relying on a specific plant).

Carbon dioxide is comfortably IECSC-listed; typically NOT on Catalog of Hazardous Chemicals at industrial grade. NOT on Highly Toxic, NOT on Easily-Made Drugs. **China ETS national emissions trading scheme since July 2021** (verify current scope against MEE). **China VAT export rebate** rate per current schedule (verify before invoicing). **Food-grade GB 1886.228-2016 E290 plus ChP for medical-grade**. Industrial CO2 is captive-by-product.

Listing and threshold

Substance Carbon dioxide (CO2) (CAS 124-38-9), CO2
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 1886.228-2016 food-grade CO2 specification (verify the current CO2-specific GB / GB-T standard at https://www.codeofchina.com/ before relying)
  • GB/T 17519-2013 Chinese SDS standard
  • GACC HS code: 281121
  • GB 6944-2012 transport: Class 2.2 (compressed UN 1013 or refrigerated liquefied UN 2187)
  • **Pharma-grade compliance with Chinese Pharmacopoeia (ChP)** where placed as medical-grade CO2 (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)
  • **China ETS (national emissions trading scheme)** covering power-sector CO2 emissions since July 2021 with planned expansion to cement + steel + aluminium 2024-2025 (verify current scope against MEE announcements before relying)
  • GB/T 17519 Chinese SDS required
  • **Food-grade GB 1886.228-2016** specification compliance for E290 use

Importer obligations

For Chinese-origin industrial CO2, no IECSC obligation falls on the foreign importer (CO2 is rarely cross-border traded at scale due to low value-density and regional captive-by-product structure). Major Chinese sources (captive by-product): Sinopec + CNPC ammonia / SMR vents, Yara China ammonia plants, COFCO Biochemical ethanol-fermentation vents, Henan Jindian Chemical, Yingde Gases, Hangzhou Hangyang.

Required documents

  • GACC export declaration HS 281121
  • GHS Chinese SDS per GB/T 17519
  • Food-grade GB 1886.228-2016 certification where applicable
  • 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)
  • **China ETS national emissions trading scheme** since July 2021 with planned 2024-2025 expansion (verify against MEE announcements)
  • NOT on Highly Toxic, NOT on Easily-Made Drugs
  • Major Chinese sources (captive by-product): Sinopec + CNPC + Yara China + COFCO Biochemical + Henan Jindian + Yingde Gases + Hangzhou Hangyang (verify each producer-site pair)
  • **Food-grade E290 carbonation / MAP / dry-ice + supercritical CO2 + shielding-gas + EOR + CCUS downstream chains**
  • CO2 not typically cross-border traded at scale (low value-density + regional captive-by-product structure)
