Manganese dioxide (MnO2) under REACH

MnO2 · 二氧化锰

Status: Registered. Manganese dioxide is fully registered under REACH. **Distinguishing pattern: produced as electrolytic (EMD, ~3.5 V cell on MnSO4 sulphate electrolyte yielding gamma-MnO2 deposit) or chemical (CMD via MnO2 ore reduction with carbon then air-roasting, yielding beta-MnO2 / pyrolusite); ~70 to 80% of global EMD consumption is alkaline + Zn-C dry-cell battery cathode active material; remaining downstream uses are ferromanganese steel deoxidiser / desulfuriser smelting (~10 to 15%) + ceramic colorant (purple / black glazes) + pigment umber + organic-synthesis oxidant (allylic alcohol oxidation) + water-treatment oxidiser. Major non-EU producers: Tronox / Cristal (Western Australia Woodie Woodie EMD + Newman ore), Tosoh (Japan Yamaguchi EMD), Mitsui Mining + Smelting (Japan), South32 (Australia + South Africa Hotazel manganese ore), Erachem Comilog (Belgium + USA Baltimore EMD), Prince Erachem; major Chinese producers Citic Dameng Mining (Guangxi) + Guizhou Redstar Developing + Hunan Tongren + Xiangtan Electrochemical Scientific + Guangxi Tianyuan; verify each producer-site pair against the producer's public website before relying.** NOT SVHC. NOT Annex XIV. **EU AD measures on Chinese-origin EMD via Reg (EC) No 221/2008 and successor measures** (verify exact current measure + duty rate against EUR-Lex https://eur-lex.europa.eu/ before invoicing).

Manganese dioxide is fully REACH-registered with mid hazard profile (Acute Tox. 4 oral / inhalation + STOT RE 1 nervous-system / lungs reflecting manganese-induced neurotoxicity / "manganism"). NOT SVHC, NOT Annex XIV. **EU AD measures on Chinese-origin electrolytic manganese dioxide (EMD) via Reg (EC) No 221/2008 and successor measures; verify exact current duty rate per producer against EUR-Lex before invoicing.** **Alkaline + Zn-C dry-cell battery cathode ~70 to 80% + ferromanganese steel ~10 to 15% + ceramic / pigment / organic-synthesis oxidant downstream chains**.

Listing and threshold

Substance Manganese dioxide (MnO2) (CAS 1313-13-9), MnO2
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

  • Acute Tox. 4 oral: H302 + Acute Tox. 4 inhalation: H332 + STOT RE 1 nervous-system / lungs: H372 per harmonised CLP (verify exact harmonised classification against ECHA Annex VI to CLP Table 3.1 before relying)
  • IARC: Manganese and inorganic manganese compounds NOT separately classified; Group 3 designation may apply (verify against https://monographs.iarc.who.int/ before relying)
  • ADR / RID: NOT regulated as dangerous goods at solid form
  • **EU AD measures on Chinese-origin electrolytic manganese dioxide (EMD) via Reg (EC) No 221/2008 and successor measures** (verify exact current measure + duty rate against EUR-Lex https://eur-lex.europa.eu/ before invoicing)

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
  • **EU AD measures on Chinese-origin EMD via Reg (EC) No 221/2008 and successor measures (verify exact current measure + duty rate 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). **EU AD on Chinese-origin EMD: verify current duty rate per producer at access.trade.gov-equivalent EU customs portal before invoicing.** Major non-EU producers: Tronox / Cristal (Western Australia Woodie Woodie EMD + Newman ore + Pinjarra), Tosoh (Japan Yamaguchi EMD), Mitsui Mining + Smelting (Japan), South32 (Australia Groote Eylandt manganese ore + South Africa Hotazel mine), Erachem Comilog (Belgium + USA Baltimore EMD); major Chinese producers Citic Dameng Mining (Guangxi Daxin) + Guizhou Redstar Developing + Hunan Tongren + Xiangtan Electrochemical Scientific + Guangxi Tianyuan; verify each producer-site pair against the producer's public website before relying.

Required documents

  • REACH registration number on EU side
  • SDS (Acute Tox. 4 oral + Acute Tox. 4 inhalation + STOT RE 1 nervous-system / lungs)
  • Customs entry HS code 282010 (manganese dioxide)
  • No ADR documentation required at solid form
  • **EU AD duty declaration where Chinese-origin EMD (verify current duty rate against EUR-Lex per producer)**

Common compliance traps

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

  • **EU AD measures on Chinese-origin electrolytic manganese dioxide (EMD) via Reg (EC) No 221/2008 and successor measures (verify exact current measure + duty rate against EUR-Lex)**
  • Acute Tox. 4 oral / inhalation + STOT RE 1 nervous-system / lungs (manganese-induced neurotoxicity / "manganism")
  • NOT SVHC, NOT Annex XIV
  • **Alkaline + Zn-C dry-cell battery cathode active material ~70 to 80% of global EMD consumption + ferromanganese steel deoxidiser / desulfuriser ~10 to 15% + ceramic colorant + pigment umber + organic-synthesis oxidant + water-treatment oxidiser downstream chains**
  • Major non-EU producers: Tronox / Cristal Australia Woodie Woodie + Tosoh Japan Yamaguchi + Mitsui + South32 + Erachem Comilog Belgium + USA Baltimore; major Chinese producers: Citic Dameng Mining Guangxi + Guizhou Redstar + Hunan Tongren + Xiangtan Electrochemical + Guangxi Tianyuan
