Ammonia (anhydrous) under IECSC

NH3 · 氨

Status: Listed. Ammonia is on the IECSC public portion. **Ammonia IS on China's Catalog of Hazardous Chemicals** + **Ammonia IS on China's Highly Toxic Chemicals Catalog**: heaviest-compliance substance in dataset alongside phenol batch 13 + formaldehyde batch 18 + benzene batch 22 + aniline batch 26 + EO batch 28 + TDI batch 31. NOT on Easily-Made Drugs Precursor Chemicals Catalog (CMEA-style retail restrictions exist but no formal precursor scheduling). **0% China VAT export rebate** for ammonia (HS 281410). China dominates global capacity (~30%, ~60-65 Mt/yr ammonia) led by Sinopec (Yueyang + Shandong + Beijing), CNPC, Sichuan Lutianhua, Huachang, Hubei Yihua, Shandong Hualu Hengsheng.

Ammonia is comfortably IECSC-listed but IS on **BOTH the Catalog of Hazardous Chemicals AND the Highly Toxic Chemicals Catalog** (heaviest-compliance substance in dataset alongside phenol batch 13 + formaldehyde batch 18 + benzene batch 22 + aniline batch 26 + EO batch 28 + TDI batch 31). **0% China VAT export rebate**. China dominates global capacity (~30%, ~60-65 Mt/yr ammonia) led by Sinopec, CNPC, Sichuan Lutianhua, Huachang, Hubei Yihua, Shandong Hualu Hengsheng. **Coal-fed Chinese ammonia (~70% of Chinese capacity) carries 2-3x higher embedded CO2 vs gas-fed alternatives**; EU CBAM Phase 1 effective 1 January 2026 reshapes EU lane economics structurally. **Green ammonia** (electrolysis-route) is rapidly emerging Chinese capacity for CBAM-compliance lanes.

Listing and threshold

Substance Ammonia (anhydrous) (CAS 7664-41-7), NH3
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
  • **Listed in China's Highly Toxic Chemicals Catalog** (Public Security Bureau supervision; same level as phenol batch 13 + formaldehyde batch 18 + benzene batch 22 + aniline batch 26 + EO batch 28 + TDI batch 31)
  • NOT on the Easily-Made Drugs Precursor Chemicals Catalog
  • GB 536-2017 specification applies for industrial-grade liquid ammonia (Chinese national standard)
  • GACC export classifications: HS 281410 (anhydrous), HS 281420 (aqueous)
  • China dominates global capacity (~30%, ~60-65 Mt/yr ammonia); ~70% via coal-fed Haber-Bosch (higher embedded CO2); ~25% via natural-gas-fed Haber-Bosch; ~5% other
  • GB 6944-2012 dangerous-goods transport classification: Class 2.3 (toxic gas), UN 1005 (refrigerated liquefied) / UN 2073 / UN 2672

Restrictions and conditions of use

  • **Hazardous Chemicals Operation Permit IS required**
  • **Highly Toxic Chemicals Public Security Bureau permit chain** required
  • Hazardous Chemicals Road Transport Permit required for road shipment
  • **0% China VAT export rebate** for ammonia (HS 281410)
  • GB/T 17519 Chinese-language SDS required for domestic distribution
  • MEE 2024 guidance restricts new coal-fed Haber-Bosch capacity; preference for natural-gas-fed + green-ammonia (electrolysis-route) capacity
  • Beijing seasonal export-quota system applies for ammonia + urea + DAP during Chinese spring application season (Feb-May tightening)

Importer obligations

For Chinese-origin ammonia exported abroad, no IECSC obligation falls on the foreign importer. **Highly Toxic Chemicals + Hazardous Chemicals dual-permit chain is the heaviest compliance overhead** (alongside phenol batch 13 + formaldehyde batch 18 + benzene batch 22 + aniline batch 26 + EO batch 28 + TDI batch 31). Major Chinese producers: Sinopec (Yueyang + Shandong + Beijing), CNPC, Sichuan Lutianhua, Huachang, Hubei Yihua, Shandong Hualu Hengsheng.

Required documents

  • GACC export declaration with HS code 281410 (anhydrous) or 281420 (aqueous)
  • Industrial-grade certificate per GB 536-2017
  • GHS-compliant SDS in Simplified Chinese per GB/T 17519-2013 (effective 31 January 2014, references UN GHS 4th revised edition; verify against the current version of GB/T 17519 at https://www.codeofchina.com/standard/GBT17519-2013.html)
  • Hazardous Chemicals Operation Permit chain documentation
  • **Highly Toxic Chemicals Public Security Bureau permit chain documentation**
  • GB 6944-2012 Class 2.3 dangerous-goods transport documentation (refrigerated liquefied)

Common compliance traps

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

  • **Highly Toxic Chemicals + Hazardous Chemicals dual-permit chain is the heaviest compliance overhead**
  • **0% China VAT export rebate**
  • **Coal-fed Chinese ammonia (~70% of Chinese capacity)** carries 2-3x higher embedded CO2 vs gas-fed alternatives; **EU CBAM Phase 1 effective 1 January 2026** reshapes EU lane economics structurally
  • Major Chinese producers: Sinopec (Yueyang + Shandong + Beijing), CNPC, Sichuan Lutianhua, Huachang, Hubei Yihua, Shandong Hualu Hengsheng
  • Production: Haber-Bosch (~96 percent globally per V29 audit; prior dataset cited ~99 percent; China split coal-fed (~70%) / natural-gas-fed (~25%) / other (~5%)
  • Beijing seasonal export-quota system for ammonia + urea + DAP during Chinese spring application season (Feb-May tightening)
  • MEE 2024 guidance prefers natural-gas-fed + green-ammonia (electrolysis-route) over coal-fed; emerging capacity additions favour cleaner routes
  • **Green ammonia** (electrolysis-route hydrogen + Haber-Bosch) is rapidly emerging Chinese capacity for CBAM-compliance lanes (Sinopec + Wanhua + Sinopharm pilot plants)
