Sodium chlorate (NaClO3) under TSCA

NaClO3 · 氯酸钠

Status: Active. Sodium chlorate is on the TSCA Active Inventory. **NOT typically Cal Prop 65 listed at sodium chlorate level** (verify against OEHHA https://oehha.ca.gov/proposition-65/proposition-65-list before relying). NO active US AD/CVD case on Chinese-origin sodium chlorate currently (verify against access.trade.gov before invoicing). **EPA FIFRA registered as herbicide / defoliant active for soya + cotton harvest desiccation** (verify current registration status against https://www.epa.gov/pesticide-registration before relying). **DOT 49 CFR Class 5.1 Division 1 oxidizer UN 1495 PG II + heightened transport security under HMR 49 CFR 172**. ATF / DEA: NOT scheduled.

Sodium chlorate is TSCA-Active with **EPA FIFRA herbicide / defoliant registration overlay** + DOT 49 CFR Class 5.1 Division 1 oxidizer UN 1495 PG II transport regime + EPCRA Section 312 Tier II reporting at 500 lb. NO active US AD/CVD; US is structurally a net-importer with Canada (Erco Worldwide + Chemtrade) + Westlake Chemicals as primary sources. **Pulp + paper ClO2 ECF bleaching ~85% + soya / cotton defoliant + chemical-oxygen-generators downstream chains**.

Listing and threshold

Substance Sodium chlorate (NaClO3) (CAS 7775-09-9), NaClO3
Regime US Toxic Substances Control Act (TSCA), administered by EPA
Jurisdiction United States of America
Status Active
Tonnage threshold TSCA Section 8(a) Chemical Data Reporting (CDR) at >25,000 lb/year per US site

Classifications under this regime

  • TSCA Active Inventory
  • OSHA PEL: not specifically established for sodium chlorate; chlorate dust may fall under OSHA PNOR (5 mg/m3 respirable + 15 mg/m3 total) under 29 CFR 1910.1000 Table Z-1 (verify against https://www.osha.gov/annotated-pels before relying)
  • IARC: Not classified (verify against https://monographs.iarc.who.int/ before relying)
  • **NOT typically Cal Prop 65 listed at sodium chlorate level** (verify against https://oehha.ca.gov/proposition-65/proposition-65-list before relying)
  • DOT 49 CFR: UN 1495 SODIUM CHLORATE Class 5.1 Division 1 oxidizer PG II
  • **EPA FIFRA herbicide / defoliant active** (soya + cotton harvest desiccation; verify against https://www.epa.gov/pesticide-registration before relying)
  • EPA Section 312 EPCRA Tier II reporting threshold: 500 lb (oxidizer, EHS-equivalent treatment)
  • CDC ATSDR ToxFAQs profile available

Restrictions and conditions of use

  • NO active US AD/CVD case on Chinese-origin sodium chlorate currently (verify against access.trade.gov before invoicing)
  • EPA FIFRA registration required where placed as herbicide / defoliant (verify against https://www.epa.gov/pesticide-registration)
  • DOT 49 CFR Class 5.1 oxidizer transport requirements UN 1495 PG II
  • EPCRA Section 312 Tier II reporting threshold 500 lb
  • ATF: NOT scheduled (sodium chlorate is NOT a Federal explosive but is an oxidizer commonly diverted to improvised explosive applications; voluntary heightened-security distribution practices)

Importer obligations

TSCA Section 13 import certification (positive). **EPA FIFRA registration required where placed as herbicide / defoliant**. DOT 49 CFR Class 5.1 oxidizer transport documentation. **US is structurally a net-importer**; major sources Canada (Erco Worldwide Saskatoon SK + North Vancouver BC + Magog QC, Chemtrade Logistics) and US domestic (Westlake Chemicals); major Chinese exporters (where price-competitive on export-licensable basis): Shandong Lubei Enterprise, Hebei Yuanli, Inner Mongolia Junzheng.

Required documents

  • TSCA Section 13 import certification
  • CBP entry HS 282911 (sodium chlorate)
  • SDS (Ox. Sol. 1 + Acute Tox. 4 oral + Eye Irrit. 2 + Aquatic Chronic 2)
  • DOT shipping papers UN 1495 Class 5.1 Division 1 PG II
  • EPA FIFRA registration certificate where placed as herbicide / defoliant
  • EPCRA Section 312 Tier II report at site if >500 lb on hand

Common compliance traps

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

  • NO active US AD/CVD case on Chinese-origin sodium chlorate currently
  • **EPA FIFRA herbicide / defoliant active (soya + cotton harvest desiccation)**
  • DOT 49 CFR Class 5.1 oxidizer UN 1495 PG II + heightened transport security
  • EPCRA Section 312 Tier II reporting threshold 500 lb
  • **Pulp + paper ClO2 ECF bleaching ~85% of US consumption + soya / cotton defoliant + chemical-oxygen-generators downstream chains**
  • **US is structurally a net-importer**; primary sources Canada (Erco Worldwide + Chemtrade) + Westlake Chemicals US domestic
