Sodium chlorate (NaClO3) under REACH

NaClO3 · 氯酸钠

Status: Registered. Sodium chlorate is fully registered under REACH. **Distinguishing pattern: produced by electrolysis of brine (NaCl + 3 H2O electrolysis at near-neutral pH yields NaClO3 + 3 H2; chlor-alkali co-product chain alongside chlorine + NaOH); ~85% of global NaClO3 consumption is feedstock for chlorine-dioxide (ClO2) generation in pulp + paper elemental-chlorine-free (ECF) bleaching; remaining downstream uses are uranium ore leaching + agricultural defoliant (soya / cotton harvest desiccant) + emergency oxygen-supply chemical-oxygen-generators (submarine + aircraft "oxygen candles") + leather + textile bleaching + match heads + minor pyrotechnic + minor pharma intermediate. Major global producers: Erco Worldwide (Canada), Akzo Nobel / Nouryon (Sweden + Finland), Kemira (Finland), Ercros (Spain), Chinese producers Shandong Lubei + Hebei Yuanli. Verify each producer-site pair against the producer's public website before relying.** **REACH Annex XVII Restriction Entry 65 prohibits placing on market or use as substance / mixture for sale to general public (consumer weed-killer use BANNED) effective 10 May 2009 per Reg (EC) 552/2009** (verify against EUR-Lex https://eur-lex.europa.eu/ before relying). NOT SVHC. NOT Annex XIV. NO active EU AD case on Chinese-origin sodium chlorate currently (verify against EUR-Lex before invoicing).

Sodium chlorate is fully REACH-registered with **Annex XVII Restriction Entry 65 prohibition on consumer weed-killer placement (effective 10 May 2009)** and **Plant Protection Products Regulation non-renewal Reg (EC) No 1039/2008 (effective 10 May 2010)**. Ox. Sol. 1 + Acute Tox. 4 oral + UN 1495 Class 5.1 PG II oxidizer. NO active EU AD. **Pulp + paper ClO2 ECF bleaching ~85% + uranium ore leaching + chemical-oxygen-generators downstream chains**. **Annex XVII 65 is the practical EU-import compliance pivot: B2B / industrial-only customer declaration mandatory.**

Listing and threshold

Classifications under this regime

  • Ox. Sol. 1: H271 + Acute Tox. 4 oral: H302 + Eye Irrit. 2: H319 + Aquatic Chronic 2: H411 per harmonised CLP (verify against ECHA Annex VI to CLP Table 3.1 before relying)

  • **REACH Annex XVII Restriction Entry 65: prohibited as plant protection product / consumer weed-killer effective 10 May 2009 per Reg (EC) 552/2009** (verify against EUR-Lex https://eur-lex.europa.eu/ before relying)
  • ADR / RID: UN 1495 SODIUM CHLORATE Class 5.1 (oxidizer) PG II (verify against current ADR at https://unece.org/transport/dangerous-goods/adr-2025-files before consigning)
  • **Plant Protection Products Regulation (EC) No 1107/2009: sodium chlorate non-renewal of approval Reg (EC) No 1039/2008 (effective 10 May 2010)** (verify against EUR-Lex https://eur-lex.europa.eu/ before relying)
  • **EU Regulation 2019/1148 on the marketing and use of explosives precursors lists sodium chlorate as a restricted explosives precursor for the general public** (verify exact Annex I / II placement plus concentration threshold against EUR-Lex https://eur-lex.europa.eu/eli/reg/2019/1148/oj before relying)

Restrictions and conditions of use

  • NOT on REACH Annex XIV authorisation list (verify against ECHA https://echa.europa.eu/authorisation-list)
  • NOT classified as SVHC (verify against ECHA https://echa.europa.eu/candidate-list-table)
  • **Annex XVII Restriction Entry 65: consumer weed-killer use BANNED in EU (verify against EUR-Lex https://eur-lex.europa.eu/)**
  • **EU Regulation 2019/1148 on explosives precursors restricts placement on the general-public market** (verify exact Annex I / II placement plus concentration threshold against EUR-Lex https://eur-lex.europa.eu/eli/reg/2019/1148/oj before invoicing)
  • NO active EU AD case on Chinese-origin sodium chlorate currently (verify against EUR-Lex before invoicing)
  • NOT in CBAM Phase 1 scope

Importer obligations

A non-EU producer cannot register directly under REACH. The EU importer of record must hold a registration or rely on an Only Representative (OR). **Annex XVII Restriction 65 enforcement: B2C consumer placement BANNED; B2B industrial / professional use permitted.** Major non-EU producers: Erco Worldwide (Canada, Saskatoon SK + North Vancouver BC + Magog QC), Chemtrade Logistics (Canada), Westlake Chemicals (USA). Major EU producers: Akzo Nobel / Nouryon (Sweden Alby + Finland Joutseno), Kemira (Finland Joutseno), Ercros (Spain Sabinanigo). Major Chinese producers: Shandong Lubei Enterprise (Wudi Shandong), Hebei Yuanli, Inner Mongolia Junzheng Energy + Chemical; verify each producer-site pair against the producer's public website before relying.

Required documents

  • REACH registration number on EU side
  • SDS (Ox. Sol. 1 + Acute Tox. 4 oral + Eye Irrit. 2 + Aquatic Chronic 2)
  • Customs entry HS code 282911 (sodium chlorate)
  • ADR transport documentation UN 1495 Class 5.1 PG II oxidizer
  • B2B / industrial-only customer declaration per Annex XVII Restriction 65

Common compliance traps

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

  • **Annex XVII Restriction Entry 65: consumer weed-killer use BANNED in EU (effective 10 May 2009 per Reg (EC) 552/2009)**
  • **Plant Protection Products Regulation non-renewal Reg (EC) No 1039/2008 effective 10 May 2010 (no longer authorised as PPP active in EU)**
  • **EU Regulation 2019/1148 explosives precursors restriction (verify exact Annex I / II placement plus concentration threshold against EUR-Lex before invoicing)**
  • Ox. Sol. 1 + Acute Tox. 4 oral + UN 1495 Class 5.1 PG II oxidizer
  • NOT SVHC, NOT Annex XIV, NO active EU AD
  • **Pulp + paper ClO2 ECF bleaching ~85% of global consumption + uranium ore leaching + agricultural defoliant (where still permitted outside EU) + chemical-oxygen-generators (submarine / aircraft "oxygen candles") + match heads downstream chains**
  • Major global producers: Erco Worldwide + Akzo Nobel / Nouryon + Kemira + Ercros + Shandong Lubei + Hebei Yuanli
