Potassium iodide (KI) under REACH

KI · 碘化钾

Status: Registered. Potassium iodide is fully registered under REACH. **Distinguishing pattern: produced via neutralisation of iodine (I2) with KOH or via reduction of KIO3 with iron / bisulfite; iodine feedstock from Chilean caliche-ore brines (SQM Atacama dominant) + Japanese / US Oklahoma gas-well brines; primary downstream uses are iodised salt fortification (food additive E916, ~50% of global consumption) + pharma thyroid blocker (potassium iodide tablets for radiation prophylaxis, NRC / EU Council Directive 2013/59/Euratom basic safety standards) + expectorant + pharma intermediate + animal-feed (EDDI alternative) + photographic emulsion. Verify each producer-site pair against the producer's public website before relying.** NOT SVHC. NOT Annex XIV. NO active EU AD case on Chinese-origin potassium iodide currently (verify against EUR-Lex https://eur-lex.europa.eu/ before invoicing). **NOT on EU Drug Precursors Regulation (EC) No 273/2004 + Regulation (EU) 2015/1011 scheduled list** (verify against EUR-Lex before relying).

Potassium iodide is fully REACH-registered with light hazard profile (Eye Irrit. 2 + STOT RE 1 thyroid chronic high-dose). NOT SVHC, NOT Annex XIV. **NOT on EU Drug Precursors scheduled list**. **Iodised salt fortification (E916) + pharma thyroid blocker for nuclear-incident prophylaxis (Council Directive 2013/59/Euratom) + expectorant + animal-feed + photographic emulsion downstream chains**. China is a major KI producer despite being a net-importer of elemental iodine feedstock.

Listing and threshold

Substance Potassium iodide (KI) (CAS 7681-11-0), KI
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 Registered
Tonnage threshold Registration required for any importer or manufacturer placing >1 t/year on the EU market

Classifications under this regime

  • Eye Irrit. 2: H319 + STOT RE 1 (thyroid) chronic high-dose typically (verify exact harmonised classification against ECHA Annex VI to CLP Table 3.1 before relying)
  • IARC: Not classified (verify against https://monographs.iarc.who.int/ before relying)
  • **NOT on EU Drug Precursors Regulation (EC) No 273/2004 + Regulation (EU) 2015/1011 scheduled list** (verify against EUR-Lex https://eur-lex.europa.eu/ before relying)
  • ADR / RID: NOT regulated as dangerous goods at solid form
  • **Ph. Eur. monograph** for pharma-grade potassium iodide (verify monograph reference against EDQM / Ph. Eur. before relying)
  • **EU Food Additive E916 calcium iodate / potassium iodide as food additive in iodised salt** (verify against EUR-Lex Reg (EC) 1333/2008 before relying)
  • **EU Council Directive 2013/59/Euratom basic safety standards: KI tablets distributed to populations within emergency planning zones for nuclear-incident thyroid prophylaxis** (verify against EUR-Lex before relying)

Restrictions and conditions of use

  • NOT on REACH Annex XIV authorisation list (verify against ECHA https://echa.europa.eu/authorisation-list)
  • NOT classified as SVHC (verify against ECHA https://echa.europa.eu/candidate-list-table)
  • NOT subject to any Annex XVII restriction
  • NO active EU AD case on Chinese-origin potassium iodide currently (verify against EUR-Lex https://eur-lex.europa.eu/ before invoicing)
  • NOT in CBAM Phase 1 scope

Importer obligations

A non-EU producer cannot register directly under REACH. The EU importer of record must hold a registration or rely on an Only Representative (OR). **Major Chinese potassium iodide producers** (China is a major KI producer despite being a net-importer of elemental iodine feedstock): Shanghai Xinbao Fine Chemical, Sichuan Xinjia, Anhui Antian Salt, Jiangsu World Chemical; verify each producer-site pair against the producer's public website before relying.

Required documents

  • REACH registration number on EU side
  • SDS (Eye Irrit. 2 + STOT RE 1 thyroid chronic high-dose)
  • Customs entry HS code 283120 (potassium iodide)
  • No ADR documentation required at solid form
  • Ph. Eur. monograph documentation for pharma-grade
  • Food additive E916 documentation where applicable per Reg (EC) 1333/2008

Common compliance traps

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

  • **Production: I2 + KOH or KIO3 reduction; iodine feedstock from Chilean caliche-ore brines (SQM Atacama) + Japanese / US Oklahoma gas-well brines (China is structurally a net-importer of elemental iodine but a major KI producer)**
  • **NOT on EU Drug Precursors scheduled list**
  • NOT SVHC, NOT Annex XIV, NO active EU AD
  • **Iodised salt food additive E916 (~50% of global KI consumption) + pharma thyroid blocker for nuclear-incident prophylaxis (Council Directive 2013/59/Euratom) + expectorant + animal-feed (EDDI alternative) + photographic emulsion downstream chains**
  • Major Chinese KI producers: Shanghai Xinbao Fine Chemical, Sichuan Xinjia, Anhui Antian Salt, Jiangsu World Chemical
