Iodine (I2) under REACH

I2 · 碘

Status: Registered. Iodine is fully registered under REACH. **Distinguishing pattern: extracted globally from Chilean caliche-ore brines (SQM Atacama Desert dominant) plus Japanese gas-well brines (Iwate + Chiba prefectures) plus US Oklahoma gas-well brines (Iofina) plus Russian gas-well brines; China is structurally a net-importer of iodine for pharma + LCD-polariser-PVA-film + animal-feed (EDDI + iodised salt) + povidone-iodine disinfectant downstream chains. 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 iodine 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** despite US DEA List II essential chemical status under 21 CFR 1310.02(b) (verify against EUR-Lex https://eur-lex.europa.eu/ and against https://www.deadiversion.usdoj.gov/ before relying; US DEA scheduling does NOT extend to EU).

Iodine is fully REACH-registered with mid hazard profile (Skin Irrit. 2 + Eye Irrit. 2 + STOT SE 3 + Acute Tox. 4 inhalation). NOT SVHC, NOT Annex XIV. **NOT on EU Drug Precursors Regulation (EC) 273/2004 + Reg 2015/1011 scheduled list** despite US DEA List II status under 21 CFR 1310.02(b) (verify against https://www.deadiversion.usdoj.gov/). ADR UN 3495 Class 8 PG III. **Pharma + LCD-polariser-film + animal-feed + povidone-iodine disinfectant downstream chains**. China is structurally a net-importer; major global producers are SQM (Chile, Atacama caliche-ore), Iofina (USA, Oklahoma gas-well), and Japanese gas-well producers (Nippon Soda + Toho Earth-tech + ISE Chemicals).

Listing and threshold

Status Registered
Tonnage threshold Registration required for any importer or manufacturer placing >1 t/year on the EU market

Classifications under this regime

  • Skin Irrit. 2: H315 + Eye Irrit. 2: H319 + STOT SE 3: H335 + Acute Tox. 4 inhalation: H332 (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; US DEA List II scheduling under 21 CFR 1310.02(b) does NOT extend to EU)
  • ADR / RID: UN 3495 IODINE Class 8 PG III corrosive solid (verify against current ADR at https://unece.org/transport/dangerous-goods/adr-2025-files before consigning)
  • **Ph. Eur. monograph** for pharma-grade iodine + iodine tincture + povidone-iodine (verify monograph reference against EDQM / Ph. Eur. before relying)
  • **EU Regulation (EU) No 528/2012 biocidal products (BPR)** evaluation for iodine + iodophors (povidone-iodine) as biocidal active in human-hygiene PT 1 + veterinary-hygiene PT 3 + food + feed PT 4 (verify against ECHA BPR database https://echa.europa.eu/ 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 iodine 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 global iodine producers** (China is structurally a net-importer, NOT a major exporter): SQM (Chile, Atacama Desert caliche-ore brines), Iofina (USA, Oklahoma gas-well brines), Nippon Soda + Toho Earth-tech + ISE Chemicals (Japan, Iwate / Chiba gas-well brines), Russian gas-well producers; verify each producer-site pair against the producer's public website before relying.

Required documents

  • REACH registration number on EU side
  • SDS (Skin Irrit. 2 + Eye Irrit. 2 + STOT SE 3 + Acute Tox. 4 inhalation)
  • Customs entry HS code 280120 (iodine)
  • ADR transport documentation UN 3495 Class 8 PG III where consigned in transport quantity (verify against current ADR at https://unece.org/transport/dangerous-goods/adr-2025-files before consigning)
  • Ph. Eur. monograph documentation for pharma-grade
  • BPR documentation where placed as biocidal active (PT 1 / PT 3 / PT 4)

Common compliance traps

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

  • **Globally extracted from Chilean caliche-ore brines (SQM Atacama dominant) + Japanese gas-well brines (Iwate / Chiba) + US Oklahoma gas-well brines (Iofina) + Russian gas-well brines; China is structurally a net-importer**
  • **NOT on EU Drug Precursors Regulation (EC) 273/2004 + Reg 2015/1011 scheduled list** despite US DEA List II status (21 CFR 1310.02(b); verify against https://www.deadiversion.usdoj.gov/)
  • ADR UN 3495 Class 8 PG III corrosive solid
  • NOT SVHC, NOT Annex XIV, NO active EU AD
  • **Pharma intermediate (iohexol + iopromide + amiodarone contrast media + povidone-iodine) + LCD-polariser-PVA-film + animal-feed (EDDI + iodised salt via KIO3 / KI) + disinfectant + dye-intermediate downstream chains**
