What is the tonnage threshold for REACH on potassium chloride (muriate of potash, mop)?

Annex V exemption: no REACH registration required regardless of tonnage

CAS 7447-40-7 · REACH · European Union

Potassium chloride (muriate of potash, MOP) under REACH

KCl · 氯化钾

Status: Exempt. Potassium chloride is **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). **Distinguishing pattern: REACH-exempt natural mineral (alongside sodium chloride batch 16) + completes K-fertiliser chain alongside KOH batch 17 (KCl is upstream feedstock for KOH via electrolysis batch 17 chain) + closes Qinghai Salt Lake Industry park chain (sister batch to NaCl batch 16) + Russia + Belarus war disruption to global potash supply 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)) + China is structurally net-IMPORTER of KCl (largest global K-fertiliser importer; ~50% of demand imported) + Beijing seasonal export-quota system (NEW combined).** No GHS classification at industrial-grade. NOT SVHC. NOT Annex XIV.

Potassium chloride is **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). **Closes K-fertiliser chain** alongside KOH batch 17 (KCl is upstream feedstock for KOH via electrolysis). NO REACH registration required. NOT SVHC. NOT in CBAM Phase 1. **Russia + Belarus war disruption** since 2022 reshaping global potash trade structurally. China is structurally net-IMPORTER (largest global K-fertiliser importer). Major Chinese producers: **Qinghai Salt Lake Industry (sister batch to NaCl batch 16)**, SDIC Lop Nor, China BlueChemical. Production: potash mining (Saskatchewan world's largest + Ural + Belarus + Israel + Jordan + Brazil + China Qinghai + Xinjiang Lop Nor). End-use: K-fertiliser (~95%), industrial chemicals (~5%, KOH chain).

Listing and threshold

Substance	Potassium chloride (muriate of potash, MOP) (CAS 7447-40-7), KCl
Regime	EU Regulation (EC) No 1907/2006: Registration, Evaluation, Authorisation and Restriction of Chemicals
Jurisdiction	European Union (EU-27 plus EEA: Iceland, Liechtenstein, Norway)
Status	Exempt
Tonnage threshold	Annex V exemption: no REACH registration required regardless of tonnage

Classifications under this regime

Annex V exempt under REACH Article 2(7)(a) (natural mineral, substance of no concern)
NO harmonised CLP classification under Reg (EC) 1272/2008 at industrial-grade level
NOT classified as DG under ADR / RID
IARC: not assigned
NOT subject to Drug Precursors or Explosives Precursors scheduling
EU food additive E 508 permitted under Reg 1333/2008
EU Reg (EU) 2019/1009 Fertiliser Regulation: KCl permitted as PFC (Product Function Category) Mineral Fertiliser

Restrictions and conditions of use

NO REACH registration required (Annex V exempt)
NOT classified as SVHC
NOT subject to any Annex XVII restriction
NO active EU AD case on Chinese-origin KCl currently (NOTE: EU active AD case on Russian + Belarusian potash from 2022 onward via Russia-sanctions; not formally AD but trade-policy-equivalent)
NOT in CBAM Phase 1 scope

Importer obligations

KCl is REACH-exempt; no REACH registration required. The dominant economic story for global KCl is **Russia + Belarus war disruption since 2022**: Russia (Uralkali + EuroChem) + Belarus (Belaruskali) combined ~40% of global potash supply pre-2022. Western sanctions on Belarus + Russia have reshaped global potash trade flows; Canadian Nutrien-Mosaic (Saskatchewan) + Israeli ICL Group (Dead Sea) + Jordanian Arab Potash + Brazilian Mosaic Cubatao production ramped to fill gaps. Major Chinese producers: Qinghai Salt Lake Industry (largest in China + sister batch to NaCl batch 16), SDIC Lop Nor (Xinjiang), China BlueChemical. China is structurally net-IMPORTER (largest global K-fertiliser importer; ~50% of demand imported).

Required documents

Customs entry with HS code 310420 (potassium chloride / muriate of potash, fertiliser-grade) or HS 283120 (technical-grade)
EU Reg 2019/1009 Fertiliser Regulation conformity declaration (PFC + CMC compliance)
European Pharmacopoeia 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.

**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, substance of no concern); alongside sodium chloride batch 16
**Russia + Belarus war disruption to global potash supply since 2022** (combined ~40% of global supply pre-2022)
**China is structurally net-IMPORTER**: largest global K-fertiliser importer; ~50% of demand imported from Belarus (pre-2022) + Canada Nutrien-Mosaic + Russia Uralkali + Israel ICL + Jordan Arab Potash + Brazil Mosaic Cubatao
Major Chinese producers: **Qinghai Salt Lake Industry (sister batch to NaCl batch 16; a leading Chinese potash producer; verify the most recent capacity and rank against the Qinghai Salt Lake Industry corporate site or ICIS before quoting largest-in-China)**, SDIC Lop Nor (Xinjiang), China BlueChemical
Production: potash mining (Saskatchewan Canada world's largest concentration; Ural Russia + Belarus + Israel + Jordan + Brazil + China Qinghai Salt Lake + Lop Nor)
End-use mix: K-fertiliser ~95% (MOP / KCl + SOP / K2SO4 + NPK blends); industrial chemicals (~5%, KOH batch 17 upstream feedstock + dye + pharmaceutical)

**Closes Qinghai Salt Lake Industry park chain** (sister batch to NaCl batch 16; world's largest single-region salt-lake-brine chemistry)
