Sodium bicarbonate (baking soda) under REACH

NaHCO3 · 碳酸氢钠

Status: Registered. Sodium bicarbonate is fully registered under REACH. **Distinguishing pattern: Solvay-process production route (NaCl plus NH3 plus CO2 plus H2O) and natural trona-derived production route (Wyoming dominant for US-natural; verify regional split against ICIS or USGS Mineral Commodity Summaries before quoting) + food-grade E500 (acidulant / leavening agent) plus pharma antacid plus animal feed plus detergent plus fire-extinguisher plus dry-sorbent FGD plus water-treatment downstream chains + low hazard profile (NOT classified as hazardous under CLP at industrial-grade purity).** No harmonised CLP entry; ECHA C&L Inventory aggregates notifier classifications: NOT typically classified as hazardous (verify against ECHA https://echa.europa.eu/information-on-chemicals before relying). NOT SVHC. NOT Annex XIV. NO active EU AD case on Chinese-origin sodium bicarbonate currently (verify against EUR-Lex https://eur-lex.europa.eu/ before invoicing). **Note: EU has historic AD measures on soda ash (sodium carbonate, CAS 497-19-8); verify scope and current status against EUR-Lex before relying on soda-ash-chain duty status.**

Sodium bicarbonate is fully REACH-registered with **low hazard profile** (NOT typically classified as hazardous). NOT SVHC, NOT Annex XIV. NO active EU AD on bicarbonate itself but **soda ash upstream has historic AD measures**; verify before relying. **Food-grade E500 plus pharma antacid plus animal feed plus detergent plus FGD plus water-treatment** downstream chains. Major Chinese producers: Sanyou Chemical Tangshan, Shandong Haitian Biochemical, Shandong Haihua Group, Inner Mongolia Berun Group, Jiangsu Salt Industry Group.

Listing and threshold

Substance Sodium bicarbonate (baking soda) (CAS 144-55-8), NaHCO3
Regime EU Regulation (EC) No 1907/2006: Registration, Evaluation, Authorisation and Restriction of Chemicals
Jurisdiction European Union (EU-27 plus EEA: Iceland, Liechtenstein, Norway)
Status Registered
Tonnage threshold Registration required for any importer or manufacturer placing >1 t/year on the EU market

Classifications under this regime

  • No harmonised CLP entry; notifier classification (per ECHA C&L Inventory): NOT typically classified as hazardous at industrial-grade purity (verify against ECHA C&L Inventory before relying)
  • IARC: Not classified
  • NOT subject to Drug Precursors or Explosives Precursors scheduling
  • ADR / RID transport classification: NOT regulated
  • **Food-grade E500 acidulant / leavening agent** (verify against EU Regulation (EC) No 1333/2008 food additive Annex II for current scope)
  • **EU Pharmacopoeia monograph** for pharma-grade sodium bicarbonate (verify monograph reference against EDQM / Ph. Eur. before relying)

Restrictions and conditions of use

  • NOT on REACH Annex XIV (verify against ECHA https://echa.europa.eu/authorisation-list)
  • NOT classified as SVHC (verify against ECHA https://echa.europa.eu/candidate-list-table)
  • NOT subject to any Annex XVII restriction
  • NO active EU AD case on Chinese-origin sodium bicarbonate currently (verify against EUR-Lex https://eur-lex.europa.eu/ before invoicing)
  • NOT in CBAM Phase 1 scope
  • **EU has historic AD measures on soda ash (sodium carbonate, CAS 497-19-8)**; verify scope and current status against EUR-Lex before relying on soda-ash-chain duty status

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). Major Chinese producers: Sanyou Chemical Tangshan, Shandong Haitian Biochemical, Shandong Haihua Group, Inner Mongolia Berun Group, Jiangsu Salt Industry Group (verify each producer-site pair against the producer's public website before relying on a specific plant).

Required documents

  • REACH registration number on EU side
  • SDS (low hazard profile)
  • Customs entry HS code 283630 (sodium bicarbonate)
  • No ADR documentation required
  • Food / pharma grade certifications where applicable (E500 / Ph. Eur.)

Common compliance traps

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

  • **Food-grade E500 acidulant / leavening plus pharma antacid plus animal feed plus detergent plus fire-extinguisher plus dry-sorbent FGD plus water-treatment downstream chains**
  • NOT SVHC, NOT Annex XIV, NO active EU AD on bicarbonate itself
  • **EU has historic AD measures on soda ash (CAS 497-19-8)**; verify before relying on soda-ash-chain duty status
  • Major Chinese producers: Sanyou Chemical Tangshan, Shandong Haitian Biochemical, Shandong Haihua Group, Inner Mongolia Berun Group, Jiangsu Salt Industry Group
  • Production: Solvay-process (NaCl plus NH3 plus CO2) and natural trona-derived (US Wyoming dominant for natural soda ash); verify regional split against ICIS or USGS Mineral Commodity Summaries before quoting
