Potassium iodide (KI) under IECSC

KI · 碘化钾

Status: Listed. Potassium iodide is on IECSC as an existing chemical. **China is a major KI producer despite being a net-importer of elemental iodine feedstock**; major Chinese producers Shanghai Xinbao Fine Chemical + Sichuan Xinjia + Anhui Antian Salt + Jiangsu World Chemical. **Drug Precursor scheduling under State Council Regulations on Administration of Precursor Chemicals (易制毒化学品管理条例, 2005) may apply to KI as iodine salt; verify exact category + concentration threshold against https://www.mps.gov.cn/ + https://www.nmpa.gov.cn/ before invoicing.** **Food additive GB 14880 / GB 26878 for iodised salt fortification** (verify against current GB before relying). **ChP (Chinese Pharmacopoeia) monograph for pharma-grade KI tablets + KI for thyroid prophylaxis** (verify against current ChP edition before relying).

IECSC treats potassium iodide as a routine listed existing chemical with **Drug Precursor scope-determination overlay (verify against MPS + NMPA + SAMR per 易制毒化学品管理条例 2005)**. **China is a major KI producer despite being a net-importer of elemental iodine**; export consignment is the typical Chinese trade direction. **Iodised salt fortification (GB 14880 / GB 26878 China Universal Salt Iodisation programme since 1993) + pharma thyroid blocker (ChP) + expectorant + animal-feed + photographic emulsion downstream chains**.

Classifications under this regime

  • IECSC Listed Existing Chemical
  • GB 30000.2 GHS classification: Eye Irrit. 2 + STOT RE 1 thyroid chronic high-dose (verify against current GB 30000-series at http://www.csres.com/ + http://www.std.samr.gov.cn/ before relying)
  • **Drug Precursor scheduling under 易制毒化学品管理条例 2005 may apply to KI as iodine salt (verify exact category + concentration threshold against https://www.mps.gov.cn/ + https://www.nmpa.gov.cn/ before relying)**
  • NOT on China Hazardous Chemicals Catalogue (2015 edition) (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
  • **ChP (Chinese Pharmacopoeia) monograph** for pharma-grade potassium iodide + KI tablets
  • **Food additive GB 14880 / GB 26878 for iodised salt fortification** (China was first major country to mandate iodised-salt fortification 1993; central role in China Universal Salt Iodisation programme)
  • IARC: Not classified

Restrictions and conditions of use

  • **Drug Precursor scheduling under 易制毒化学品管理条例 2005 may apply (verify exact scope against MPS + NMPA + SAMR before invoicing)**
  • GB 30000.2 GHS labelling required
  • Customs HS 283120
  • No CBAM equivalent in Chinese domestic regulation
  • NOT subject to active Chinese AD/CVD on potassium iodide
  • **Food additive GB 14880 / GB 26878 + ChP pharma-grade overlay**

Importer obligations

Chinese importer of record must hold IECSC listing reliance + **Drug Precursor scope determination (MPS + NMPA + SAMR)** under 易制毒化学品管理条例 2005 for industrial-form KI. China is a major KI producer; export consignment to overseas markets is the typical Chinese trade direction.

Required documents

  • **Drug Precursor scope determination (MPS + NMPA + SAMR)** per 易制毒化学品管理条例 2005
  • GB-compliant SDS in Chinese (Eye Irrit. 2 + STOT RE 1 thyroid chronic high-dose)
  • China Customs (CCS) declaration HS 283120
  • ChP monograph documentation where pharma-grade
  • GB 14880 / GB 26878 food additive documentation where iodised-salt-fortification grade

Common compliance traps

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

  • **Drug Precursor scope determination required under 易制毒化学品管理条例 2005 (verify against MPS + NMPA + SAMR)**
  • **China is a major KI producer despite being a net-importer of elemental iodine feedstock**; major producers Shanghai Xinbao + Sichuan Xinjia + Anhui Antian Salt + Jiangsu World Chemical
  • GB 30000.2 GHS classification (Eye Irrit. 2 + STOT RE 1 thyroid chronic high-dose)
  • NOT regulated as dangerous goods at solid form
  • **Iodised salt fortification (GB 14880 / GB 26878 China Universal Salt Iodisation programme) + pharma thyroid blocker (ChP) + expectorant + animal-feed + photographic emulsion downstream chains**
  • NOT subject to active Chinese AD/CVD
