Potassium chloride (muriate of potash, MOP) under IECSC

KCl · 氯化钾

Status: Listed. Potassium chloride is on the IECSC public portion. NOT on China's Catalog of Hazardous Chemicals. NOT on Highly Toxic Chemicals Catalog. NOT on Easily-Made Drugs Catalog. **Light IECSC-side regulatory profile alongside sodium chloride batch 16 + glycerol batch 35 + sodium carbonate batch 36**. **China is structurally net-IMPORTER (largest global K-fertiliser importer; ~50% of demand imported)**. Beijing seasonal export-quota system applies. **0% China VAT export rebate** for KCl (Beijing food-security signal; same as urea batch 5 + DAP batch 11 + AN batch 41).

KCl is comfortably IECSC-listed with **light IECSC-side regulatory profile alongside sodium chloride batch 16 + glycerol batch 35 + sodium carbonate batch 36**. **0% China VAT export rebate** (Beijing food-security signal). **China is structurally net-IMPORTER** (~50% of K-fertiliser demand imported). Major Chinese producers: **Qinghai Salt Lake Industry (sister batch to NaCl batch 16)**, SDIC Lop Nor (Xinjiang), China BlueChemical.

Listing and threshold

Substance Potassium chloride (muriate of potash, MOP) (CAS 7447-40-7), KCl
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 NOT required

Classifications under this regime

  • Listed on IECSC
  • NOT on China's Catalog of Hazardous Chemicals
  • NOT on China's Highly Toxic Chemicals Catalog
  • NOT on the Easily-Made Drugs Precursor Chemicals Catalog
  • GB 6549-2011 specification applies for industrial-grade KCl (Chinese national standard)
  • GACC export classifications: HS 310420 (potassium chloride / MOP fertiliser-grade), HS 283120 (technical-grade)
  • Production: Qinghai Salt Lake Industry (largest in China; salt-lake brine evaporation) + SDIC Lop Nor (Xinjiang sulphate-of-potash SOP) + China BlueChemical

Restrictions and conditions of use

  • NO Hazardous Chemicals Operation Permit required
  • **0% China VAT export rebate** for KCl (HS 310420; Beijing food-security signal)
  • Beijing seasonal export-quota Feb-May (parallel to urea + DAP + AN + AS fertiliser chain)
  • GB/T 17519 Chinese-language SDS NOT specifically required (no GHS classification)

Importer obligations

For Chinese-origin KCl exported abroad, no IECSC obligation falls on the foreign importer. **China is structurally net-IMPORTER (~50% of K-fertiliser demand imported)**; Chinese KCl exports limited. Major Chinese producers: **Qinghai Salt Lake Industry (sister batch to NaCl batch 16; a leading Chinese potash producer using salt-lake-brine evaporation; verify the most recent capacity and largest-in-China rank against the corporate site or ICIS before relying)**, SDIC Lop Nor (Xinjiang SOP), China BlueChemical.

Required documents

  • GACC export declaration with HS code 310420 (fertiliser-grade) or 283120 (technical-grade)
  • Industrial-grade certificate per GB 6549-2011
  • Standard commercial invoice and packing list

Common compliance traps

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

  • **Light IECSC-side regulatory profile alongside sodium chloride batch 16 + glycerol batch 35 + sodium carbonate batch 36**
  • **0% China VAT export rebate** (Beijing food-security signal)
  • Beijing seasonal export-quota Feb-May
  • **China is structurally net-IMPORTER**; Chinese KCl exports limited
  • Major Chinese producers: **Qinghai Salt Lake Industry (sister batch to NaCl batch 16)**, SDIC Lop Nor (Xinjiang), China BlueChemical
  • Russia + Belarus war disruption since 2022 makes Chinese KCl supply structurally important to global trade flows in 2022-2025 period
