Potassium peroxydisulfate (K2S2O8) under AICIS

K2S2O8 · 过硫酸钾

Status: Listed. Potassium peroxydisulfate is on the AICIS Inventory of Industrial Chemicals as a Listed Industrial Chemical. **SUSMP / Poisons Standard Schedule 5 typically** (verify exact schedule + concentration threshold against the current Poisons Standard before relying). NO active Australian AD/CVD case on Chinese-origin potassium peroxydisulfate currently (verify against the current Anti-Dumping Commission case list before relying). ChAFTA preferential zero-duty applies for Chinese-origin imports. **Australian Security-Sensitive oxidiser controls may apply at certain quantities** (verify against ASIO / Department of Home Affairs https://www.homeaffairs.gov.au/ before relying). **Australia is structurally a net-importer of K2S2O8** (no major domestic persulfate production); imported for emulsion polymerisation initiator + electronic-industry etchant + cosmetics hair-bleaching sectors.

AICIS treats potassium peroxydisulfate as a Listed Industrial Chemical with **SUSMP Schedule 5 + Resp. Sens. 1 (hairdresser asthma) + Security-Sensitive oxidiser controls (ASIO / Department of Home Affairs) overlay**. NO active Australian AD/CVD. ChAFTA preferential zero-duty. ADG UN 1492 Class 5.1 PG III oxidiser. **Australia structurally net-importer**; primary sources China (Yatai Chemical Liaoning + Wuxi Honour Jiangsu + Hebei Jiheng + ABA Chemicals Jiangyin + Yatai Foshan) + Germany / USA (United Initiators) + Japan (Mitsubishi Gas Chemical).

Restrictions and conditions of use

  • **SUSMP / Poisons Standard Schedule 5 typically (verify exact schedule)**
  • **Australian Security-Sensitive oxidiser controls may apply (ASIO / Department of Home Affairs)** (verify against https://www.homeaffairs.gov.au/)
  • NO active Australian AD/CVD case on Chinese-origin potassium peroxydisulfate currently

Importer obligations

AICIS registration required. **Australian Security-Sensitive oxidiser controls may apply per ASIO / Department of Home Affairs** (verify against https://www.homeaffairs.gov.au/ before invoicing). **Australia is structurally a net-importer of K2S2O8**; primary sources China (Yatai Chemical Liaoning + Wuxi Honour Jiangsu + Hebei Jiheng + ABA Chemicals Jiangyin + Yatai Foshan) + Germany / USA (United Initiators) + Japan (Mitsubishi Gas Chemical).

Required documents

  • AICIS registration certificate (annual)
  • WHS-compliant SDS (Ox. Sol. 3 + Resp. Sens. 1 + Skin Sens. 1 + Acute Tox. 4 inhalation)
  • Customs entry (ICS / ABF) with HS 283340
  • ChAFTA Form CO
  • ADG transport documentation UN 1492 Class 5.1 PG III oxidiser
  • Security-Sensitive oxidiser handling documentation where applicable

Common compliance traps

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

  • AICIS registration must be CURRENT at customs clearance
  • **SUSMP / Poisons Standard Schedule 5 + Resp. Sens. 1 (hairdresser asthma) + Australian Security-Sensitive oxidiser controls (ASIO / Department of Home Affairs)**
  • NO active Australian AD/CVD case
  • ChAFTA preferential zero-duty applies
  • ADG UN 1492 Class 5.1 PG III oxidiser + ATEX dust-explosion hazard
  • Australia structurally net-importer; primary sources China + Germany + USA + Japan
