Manganese dioxide (MnO2) under IECSC

MnO2 · 二氧化锰

Status: Listed. Manganese dioxide is on IECSC as an existing chemical. **China is the dominant global producer of electrolytic manganese dioxide (EMD)** with major capacity in Guangxi (Citic Dameng Mining Daxin + Guangxi Tianyuan) + Guizhou (Guizhou Redstar Developing) + Hunan (Hunan Tongren + Xiangtan Electrochemical Scientific). Subject to **historical US AD/CVD A-570-919 / C-570-920 + EU AD Reg (EC) No 221/2008 + successor measures** (verify exact current measures + duty rates against https://access.trade.gov/ + EUR-Lex before invoicing). NOT on China Hazardous Chemicals Catalogue (2015 edition) at MnO2 level (verify against https://www.mem.gov.cn/ before relying).

IECSC treats manganese dioxide as a routine listed existing chemical. **China is the dominant global producer of electrolytic manganese dioxide (EMD)** with major capacity in Guangxi + Guizhou + Hunan. **Subject to historical US AD/CVD A-570-919 / C-570-920 + EU AD Reg (EC) 221/2008 + successor measures on EMD (verify exact current measures + duty rates per producer against access.trade.gov + EUR-Lex before invoicing).** **Alkaline + Zn-C battery cathode ~70 to 80% + ferromanganese steel ~10 to 15% downstream chains**.

Listing and threshold

Substance Manganese dioxide (MnO2) (CAS 1313-13-9), MnO2
Regime China Inventory of Existing Chemical Substances (IECSC), administered by Ministry of Ecology and Environment (MEE)
Jurisdiction People's Republic of China
Status Listed
Tonnage threshold New Chemical Substance Notification (NCSN) under MEE Decree 12 not required (existing chemical)

Classifications under this regime

  • IECSC Listed Existing Chemical
  • GB 30000 GHS classification: Acute Tox. 4 oral + Acute Tox. 4 inhalation + STOT RE 1 nervous-system / lungs (verify against current GB 30000-series at http://www.csres.com/ + http://www.std.samr.gov.cn/ before relying)
  • NOT on China Hazardous Chemicals Catalogue (2015 edition) at MnO2 level (verify against https://www.mem.gov.cn/ before relying)
  • JT/T 617 / GB 12268 hazardous-goods transport: NOT regulated as dangerous goods at solid form
  • **Subject to historical US AD/CVD A-570-919 / C-570-920 + EU AD Reg (EC) 221/2008 + successor measures on EMD** (verify exact current measures + duty rates against https://access.trade.gov/ + EUR-Lex before invoicing)
  • IARC: Manganese and inorganic manganese compounds NOT separately classified (verify against https://monographs.iarc.who.int/ before relying)

Restrictions and conditions of use

  • GB 30000 GHS labelling required
  • Customs HS 282010
  • No CBAM equivalent in Chinese domestic regulation
  • NOT subject to active Chinese AD/CVD on inbound Mn ore (China is structurally a net-importer of high-grade Mn ore; major exporter of EMD)
  • **Historic Chinese EMD industry consolidation under State Council environmental compliance enforcement (battery-grade EMD facilities subject to wastewater discharge limits)** (verify against current MEE guidance before relying)

Importer obligations

Chinese importer of record must hold IECSC listing reliance. **China is a major EMD exporter; export consignment to US / EU / Australia / Korea requires AD/CVD scope determination at destination per case-deposit rate per producer.** Mn ore inbound: major sources South Africa (South32 Hotazel + Tshipi e Ntle Mining + Assmang), Australia (South32 Groote Eylandt + Element 25 Butcherbird), Gabon (Eramet Comilog Moanda).

Required documents

  • GB-compliant SDS in Chinese (Acute Tox. 4 oral + Acute Tox. 4 inhalation + STOT RE 1 nervous-system / lungs)
  • China Customs (CCS) declaration HS 282010
  • Mn ore inbound: applicable inbound documentation per Chinese inspection regime (CIQ)
  • **EMD outbound: AD/CVD documentation per destination case (verify against https://access.trade.gov/ + EUR-Lex per producer)**

Common compliance traps

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

  • **China is the dominant global producer of EMD**; major Chinese producers Citic Dameng Mining Guangxi Daxin + Guizhou Redstar + Hunan Tongren + Xiangtan Electrochemical + Guangxi Tianyuan
  • **Subject to historical US AD/CVD A-570-919 / C-570-920 + EU AD Reg (EC) 221/2008 + successor measures on Chinese-origin EMD (verify per producer at access.trade.gov + EUR-Lex)**
  • GB 30000 GHS classification (Acute Tox. 4 oral + Acute Tox. 4 inhalation + STOT RE 1 nervous-system / lungs)
  • NOT regulated as dangerous goods at solid form
  • **Alkaline + Zn-C dry-cell battery cathode ~70 to 80% of global EMD consumption + ferromanganese steel ~10 to 15% + ceramic / pigment / organic-synthesis oxidant downstream chains**
  • NOT on China Hazardous Chemicals Catalogue at MnO2 level
