Sodium bicarbonate (baking soda) under K-REACH

NaHCO3 · 碳酸氢钠

Status: Registered. Sodium bicarbonate is registered under K-REACH. NOT on Korea TCCA Toxic Chemicals list (verify against the current TCCA Toxic Chemicals list at https://www.nics.go.kr/ before relying). NOT on Korean Drug Management Act precursor list. NO active Korean AD/CVD case on Chinese-origin sodium bicarbonate currently (verify against https://www.kita.org/ or Korea Trade Commission filings before invoicing). **Korean Food Code recognises sodium bicarbonate as a food additive** (verify against MFDS / Korean Food Code before relying). Korea has limited domestic Solvay-process sodium bicarbonate production; structurally net-importer for food-grade plus pharma plus industrial sectors. KCFTA preferential zero-duty applies for Chinese-origin imports.

K-REACH treats sodium bicarbonate as a routine registered substance with no TCCA overlay. Korea limited domestic Solvay-process bicarbonate production; structurally net-importer. NO active Korean AD/CVD case. **Sodium bicarbonate distinguishing pattern across all 5 regimes**: Solvay-process production route (NaCl plus NH3 plus CO2 plus H2O) and natural trona-derived production route (US Wyoming dominant) + food-grade E500 plus pharma antacid plus animal feed plus detergent plus fire-extinguisher plus dry-sorbent FGD plus water-treatment downstream chains + low hazard profile across regimes + soda ash (CAS 497-19-8) upstream has historic AD context (EU and US) + China VAT export rebate.

Listing and threshold

Substance Sodium bicarbonate (baking soda) (CAS 144-55-8), NaHCO3
Regime Korea Act on the Registration and Evaluation of Chemicals (Act No. 11789, "K-REACH" amended 2018)
Jurisdiction Republic of Korea
Status Registered
Tonnage threshold K-REACH registration required for existing chemicals manufactured or imported >1 tonne/year (verified per Korean Ministry of Environment / NIER guidance, https://chemical.chemlinked.com/chempedia/k-reach; threshold for new substances was reduced from 0.1 t/y to 1 t/y effective 1 January 2025 per K-REACH 2025 amendment)

Classifications under this regime

  • Korean GHS classification: NOT typically classified as hazardous
  • NOT on Korea TCCA Toxic Chemicals list
  • NOT on Korean Drug Management Act precursor list
  • Korean Customs Service (KCS) HS code: 283630
  • **Korean Food Code food additive** (verify against MFDS / Korean Food Code before relying)
  • IARC: Not classified

Restrictions and conditions of use

  • No TCCA Toxic Chemicals Handling Permit required
  • KOSHA MSDS in Korean required at workplace (low hazard)
  • NO active Korean AD/CVD case on Chinese sodium bicarbonate currently
  • KCFTA preferential zero-duty applies (HS 283630)
  • Korean Food Code compliance for food-grade use

Importer obligations

Korean importer of record must hold K-REACH registration. Korea has limited domestic Solvay-process bicarbonate production; structurally net-importer.

Required documents

  • K-REACH registration number on Korean side
  • Korean MSDS (low hazard profile)
  • KCS declaration with HS 283630
  • China-Korea FTA Form CO
  • Korean Food Code certification for food-grade use

Common compliance traps

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

  • Korea limited domestic Solvay-process bicarbonate production; structurally net-importer
  • KCFTA preferential zero-duty applies
  • NO active Korean AD/CVD case
  • NOT on TCCA Toxic Chemicals list
  • Korean Food Code food-additive compliance for food-grade use
