Propylene (propene) under IECSC

C3H6 · 丙烯

Status: Listed. Propylene is on the IECSC public portion as a foundational steam-cracker plus refinery C3 product. New-substance notification under MEE Decree No. 7 (2010) is NOT required. **Propylene IS on China's Catalog of Hazardous Chemicals** (Flam. Gas 1A plus Press. Gas classification matching EU REACH harmonised). Hazardous Chemicals Operation Permit IS required for production / storage / distribution. NOT on Highly Toxic Chemicals Catalog. NOT on Easily-Made Drugs Precursor Chemicals Catalog. **0% China VAT export rebate** for propylene (HS 290122) reflects Beijing aromatic-petrochemical export-discouragement signal (similar to ethylene plus benzene plus phenol plus methanol pattern). China dominates global propylene capacity (verify percent-of-global share against ICIS or S&P Commodity Insights before quoting; prior industry reports cited a 35 to 40 percent share at ~50 Mt/yr) led by Sinopec multi-site, CNPC, Hengli Petrochemical Dalian, Zhejiang Petrochemical Zhoushan / ZRCC, Shenghong Petrochemical Lianyungang Xuwei, Wanhua Chemical Yantai.

Propylene is comfortably IECSC-listed but IS on Catalog of Hazardous Chemicals (Hazardous Chemicals Operation Permit chain required). NOT on Highly Toxic Chemicals Catalog. NOT on Easily-Made Drugs Catalog. **0% China VAT export rebate** is structural Beijing aromatic-petrochemical export-discouragement signal. China dominates global capacity led by Sinopec multi-site, CNPC, Hengli Petrochemical Dalian, Zhejiang Petrochemical Zhoushan / ZRCC, Shenghong Petrochemical Lianyungang Xuwei, Wanhua Chemical Yantai. Production: steam-cracker C3 fraction (~70 percent globally) plus FCC off-gas (~25 percent) plus PDH (~5 percent growing). End-use: polypropylene (~65 percent), propylene oxide (~10 percent), acrylonitrile (~7 percent), acrylic acid (~6 percent), oxo-alcohols (~5 percent), cumene (~5 percent). **Propylene is structurally bulk-trade-limited**.

Listing and threshold

Substance Propylene (propene) (CAS 115-07-1), C3H6
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 applies. Hazardous Chemicals Operation Permit required regardless of volume

Classifications under this regime

  • Listed in China's Catalog of Hazardous Chemicals
  • NOT on China's Highly Toxic Chemicals Catalog
  • NOT on the Easily-Made Drugs Precursor Chemicals Catalog
  • GB/T 7716-2014 specification applies for industrial-grade propylene (Chinese national standard; verify against the current version at https://www.codeofchina.com/ before relying)
  • GB/T 17519-2013 Chinese-language SDS standard applies (effective 31 January 2014, references UN GHS 4th revised edition; verify against the current version at https://www.codeofchina.com/standard/GBT17519-2013.html)
  • GACC export classification: HS 290122 (propylene)
  • GB 6944-2012 dangerous-goods transport classification: Class 2.1 (flammable gas), UN 1077 (refrigerated liquefied or compressed)

Restrictions and conditions of use

  • **Hazardous Chemicals Operation Permit IS required**
  • Hazardous Chemicals Road Transport Permit required
  • **0% China VAT export rebate** for propylene (HS 290122); reflects Beijing aromatic-petrochemical export-discouragement signal
  • GB/T 17519 Chinese-language SDS required for domestic distribution
  • MEE 2024 guidance prefers steam-cracker C3 plus PDH integrated capacity additions
  • Chinese capacity additions 2024-2026 (Hengli Phase 4, Zhejiang Petrochemical Phase 3, Shenghong Phase 2, Wanhua Yantai expansion) extend Chinese capacity rapidly toward dominance

Importer obligations

For Chinese-origin propylene exported abroad, no IECSC obligation falls on the foreign importer. **Propylene is structurally bulk-trade-limited**: most Chinese propylene is captive within integrated steam-cracker / refinery / PDH complexes feeding directly into polypropylene batch 47 plus propylene oxide batch 29 plus acrylic acid batch 39 plus acrylonitrile batch 38 plus oxo-alcohols plus cumene route. Major Chinese producers: Sinopec multi-site, CNPC, Hengli Petrochemical Dalian, Zhejiang Petrochemical Zhoushan / ZRCC, Shenghong Petrochemical Lianyungang Xuwei, Wanhua Chemical Yantai (verify each producer-site pair against the producer's public website before relying on a specific plant).

Required documents

  • GACC export declaration with HS code 290122
  • Industrial-grade certificate per GB/T 7716-2014
  • GHS-compliant SDS in Simplified Chinese per GB/T 17519-2013
  • Hazardous Chemicals Operation Permit chain documentation
  • Hazardous Chemicals Road Transport Permit
  • GB 6944-2012 Class 2.1 dangerous-goods transport documentation

Common compliance traps

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

  • Hazardous Chemicals Operation Permit chain is the dominant operational complexity
  • **0% China VAT export rebate** is structural Beijing aromatic-petrochemical export-discouragement signal
  • NOT on Highly Toxic Chemicals Catalog
  • NOT on Easily-Made Drugs Catalog
  • Major Chinese producers concentrated at coastal Sinopec plus CNPC plus Hengli plus Zhejiang Petrochemical / ZRCC plus Shenghong plus Wanhua mega-complexes
  • Production routes: steam-cracker C3 fraction (~70 percent), FCC refinery off-gas (~25 percent), PDH propane dehydrogenation (~5 percent and growing); China PDH growth driven by US-shale-derived propane import
  • **Propylene is structurally bulk-trade-limited** from China
  • End-use mix: polypropylene batch 47 (~65 percent), propylene oxide batch 29 (~10 percent), acrylonitrile batch 38 (~7 percent), acrylic acid batch 39 (~6 percent), oxo-alcohols (~5 percent), cumene route to phenol batch 13 plus acetone batch 15 (~5 percent), other (~2 percent)
