Iodine (I2) under IECSC

I2 · 碘

Status: Listed. Iodine is on IECSC as an existing chemical. **China is structurally a net-importer of iodine** for pharma (iohexol + iopromide + amiodarone contrast media + povidone-iodine) + LCD-polariser-PVA-film + animal-feed (EDDI + iodised salt via KIO3 / KI) + disinfectant downstream chains; primary import sources are Chile (SQM Atacama caliche-ore brines) + Japan (Iwate / Chiba gas-well brines) + Russia. **China State Council Regulations on Administration of Precursor Chemicals (易制毒化学品管理条例, 2005) schedule iodine** with concentration thresholds requiring **MPS (Ministry of Public Security) + NMPA + SAMR registration + import permit + transport permit + record-keeping** (verify exact category + concentration threshold against https://www.mps.gov.cn/ + https://www.nmpa.gov.cn/ before invoicing).

IECSC treats iodine as a routine listed existing chemical with **Drug Precursor scheduling overlay under 易制毒化学品管理条例 2005: MPS + NMPA + SAMR registration + import permit + transport permit + record-keeping required**. **China is structurally a net-importer** with Chile (SQM Atacama caliche-ore) + Japan (Iwate / Chiba gas-well) + Russia as primary sources. **Pharma + LCD-polariser-film + animal-feed + povidone-iodine disinfectant downstream chains**. The Drug Precursor scheduling overlay is the import-screening pivot for any Chinese-bound iodine consignment.

  • IARC: Not classified (verify against https://monographs.iarc.who.int/ before relying)

Restrictions and conditions of use

  • **Drug Precursor scheduling under 易制毒化学品管理条例 2005: MPS + NMPA + SAMR registration + import permit + transport permit + record-keeping required for distributors and importers** (verify exact category + concentration threshold against https://www.mps.gov.cn/ + https://www.nmpa.gov.cn/ before invoicing)
  • GB 30000.2 GHS labelling required
  • Customs HS 280120
  • No CBAM equivalent in Chinese domestic regulation

Importer obligations

Chinese importer of record must hold IECSC listing reliance + **Drug Precursor import permit (MPS + NMPA + SAMR)** under 易制毒化学品管理条例 2005 for industrial-form iodine. China is structurally a net-importer; primary sources Chile (SQM Atacama caliche-ore) + Japan (Iwate / Chiba gas-well) + Russia.

Required documents

  • **Drug Precursor import permit (MPS + NMPA + SAMR)** per 易制毒化学品管理条例 2005
  • GB-compliant SDS in Chinese (Skin Irrit. 2 + Eye Irrit. 2 + STOT SE 3 + Acute Tox. 4)
  • GB hazardous-goods transport documentation UN 3495 Class 8 PG III
  • China Customs (CCS) declaration HS 280120
  • ChP monograph documentation where pharma-grade
