Potassium chloride (muriate of potash, MOP) under K-REACH
KCl · 氯化钾
Status: Registered. Potassium chloride is registered under K-REACH and listed as a Priority Existing Chemical (PEC). NOT on Korea TCCA Toxic Chemicals list. NOT on Korean Drug Management Act precursor list. NO active Korean AD/CVD case. Korea has no domestic potash production; structurally net-importer for fertiliser sector. KCFTA preferential zero-duty applies for Chinese-origin imports.
K-REACH treats KCl as a routine PEC-registered substance with no TCCA overlay. Korea has no domestic potash production; structurally net-importer (~100% of demand). Korean potash imports primarily from Canadian Nutrien-Mosaic + Russian Uralkali (pre-2022 sanctions) + Israeli ICL Group. **Potassium chloride distinguishing pattern across all 5 regimes**: REACH-EXEMPT under Article 2(7) Annex V (verify exact subparagraph (a) or (b) against https://reachonline.eu/reach/en/annex-v.html before relying) (natural mineral, alongside sodium chloride batch 16) + completes K-fertiliser chain alongside KOH batch 17 (KCl is upstream feedstock for KOH via electrolysis chain) + closes Qinghai Salt Lake Industry park chain (sister batch to NaCl batch 16) + Russia + Belarus war disruption to global potash supply since 2022 (Russia plus Belarus combined approximately 40 percent of global potash supply (verify against ICIS, USGS Mineral Commodity Summaries, or International Fertilizer Association statistics before quoting a specific share) pre-2022) + China is structurally net-IMPORTER (largest global K-fertiliser importer; ~50% of demand imported) + Beijing seasonal export-quota system + 0% China VAT export rebate.
Listing and threshold
| Substance | Potassium chloride (muriate of potash, MOP) (CAS 7447-40-7), KCl |
|---|---|
| Regime | Korea Act on the Registration and Evaluation of Chemicals (Act No. 11789, "K-REACH" amended 2018) |
| Jurisdiction | Republic of Korea |
| Status | Registered |
| Tonnage threshold | K-REACH registration required for existing chemicals manufactured or imported >1 tonne/year (verified per Korean Ministry of Environment / NIER guidance, https://chemical.chemlinked.com/chempedia/k-reach; threshold for new substances was reduced from 0.1 t/y to 1 t/y effective 1 January 2025 per K-REACH 2025 amendment) |
Classifications under this regime
- NOT classified under Korean GHS at industrial-grade
- NOT on Korea TCCA Toxic Chemicals list
- NOT on Korean Drug Management Act precursor list
- Korean Customs Service (KCS) HS code: 310420 (fertiliser-grade), 283120 (technical-grade)
- Korean Pharmacopoeia (KP) monograph for pharmaceutical-grade KCl
Restrictions and conditions of use
- No TCCA Toxic Chemicals Handling Permit required
- NO active Korean AD/CVD case
- KCFTA preferential zero-duty applies
Importer obligations
The Korean importer of record must hold K-REACH registration. Korea has no domestic potash production; structurally net-importer (~100% of demand imported, primarily from Canadian Nutrien-Mosaic + Russian Uralkali pre-2022 + Israeli ICL Group).
Required documents
- K-REACH registration number on Korean side
- Korean Customs Service (KCS) declaration with HS code 310420
- China-Korea FTA Form CO certificate of origin for preferential treatment
- Korean Pharmacopoeia (KP) conformity declaration for pharmaceutical-grade lots
Common compliance traps
The pitfalls that have bitten importers on this lane in the past. None of these is theoretical.
- Korea has no domestic potash production; structurally net-importer (~100%)
- KCFTA preferential zero-duty applies but Chinese KCl exports structurally limited (China net-importer)
- NO active Korean AD/CVD case
- NOT on TCCA Toxic Chemicals list

Glossary
K-REACH, K-REACH
South Korean Act on the Registration and Evaluation of Chemicals, the Korean equivalent of EU REACH. Requires registration of substances manufactured in or imported into Korea above 1 tonne per year. Administered by the Ministry of Environment through NIER. Includes phase-in registration tiers, joint submission requirements, and a designated 'Only Representative' mechanism for non-Korean manufacturers.
