Sodium chloride under K-REACH

NaCl · 氯化钠

Status: Registered. Sodium chloride is registered under K-REACH and listed as a Priority Existing Chemical (PEC). Korean GHS classification matches REACH (no classification at industrial-grade level). NOT on Korea TCCA Toxic Chemicals list, NOT on Korean Drug Management Act precursor list. **Lightest K-REACH-side regulatory profile in the dataset.** **Korea is structurally NaCl net-importer**: domestic salt production capacity is limited (Sinanseom solar-evaporation Jeolla-do, Jeju Island secondary) and ~85% of Korean salt demand is imported, primarily from Australia (Cheetham Salt), China (Qinghai Salt Lake Industry, Shandong Sea Salt), India (Gujarat solar-evaporation), and Mexico (Exportadora de Sal Guerrero Negro). Korean chlor-alkali consumers (LG Chem Yeosu, Hanwha Solutions Yeosu, Lotte Chemical Yeosu, OCI Chemical Pohang) drive captive salt demand. KCFTA preferential zero-duty applies for Chinese-origin imports.

K-REACH treats sodium chloride as a routine PEC-registered substance with the **lightest K-REACH-side regulatory profile in the dataset**: no TCCA, no Drug Management Act, no CAPP, no MSDS specifically required (no GHS classification). **Korea is structurally NaCl net-importer**: ~85% of Korean salt demand is imported, primarily from Australia (Cheetham Salt premium solar-evaporation, ~40%), China (Qinghai Salt Lake + Shandong Sea Salt, ~25%), India (Gujarat solar-evaporation, ~15%), Mexico (Guerrero Negro, ~10%). Korean chlor-alkali consumers (LG Chem Yeosu, Hanwha Solutions Yeosu, Lotte Chemical Yeosu, OCI Chemical Pohang) drive captive salt demand. KCFTA preferential zero-duty supports Chinese-origin supply; Australian (KAFTA), Indian (CEPA), Mexican alternatives also enjoy preferential rates. NO active Korean AD/CVD case. **Sodium chloride distinguishing pattern across all 5 regimes**: lightest regulatory profile in the dataset; REACH-exempt (Annex V), no GHS, no AD/CVD, no precursor scheduling, no CBAM. Chlor-alkali feedstock loop closes the dataset: ~4 tonnes NaCl per tonne combined Cl2 + NaOH structurally couples to caustic soda (batch 1), HCl (batch 4), PVC (batch 10) markets.

Listing and threshold

Substance Sodium chloride (CAS 7647-14-5), NaCl
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

  • NO Korean GHS classification at industrial-grade level
  • NO Signal word, NO GHS pictograms, NO hazard statements
  • Korea Occupational Safety and Health Act (KOSHA) workplace exposure standard: NO specific PEL (general nuisance dust)
  • NOT on Korea TCCA Toxic Chemicals list
  • NOT on Korea Drug Management Act precursor list
  • Korean Customs Service (KCS) HS code: 2501
  • Listed in K-REACH database under "general industrial use, no hazard"
  • NOT classified as carcinogen, mutagen, or reproductive toxicant under Korean GHS
  • Korean Food Standards Codex Article 4 permits sodium chloride as food additive E 500

Restrictions and conditions of use

  • No TCCA Toxic Chemicals Handling Permit required
  • No Chemical Accident Prevention Plan (CAPP) required
  • No Korean Drug Management Act precursor obligations
  • Korea Industrial Safety and Health Act (KOSHA) MSDS in Korean NOT specifically required (no GHS classification)
  • Korea Customs Service requires K-REACH registration number on import declaration
  • No active Korean AD/CVD case on Chinese-origin sodium chloride
  • KCFTA preferential zero-duty applies to Chinese-origin sodium chloride (HS 2501); verify producer-specific eligibility (Form CO certified by Chinese authority)
  • Korea Food and Drug Administration (KFDA) Food Codex applies for food-grade lots

Importer obligations

The Korean importer of record must hold K-REACH registration in their own name or rely on an Only Representative (OR). For sodium chloride this is a routine PEC registration. **Lightest K-REACH-side regulatory profile in the dataset**: no TCCA, no Drug Management Act, no CAPP, no MSDS specifically required (no GHS classification). Korea is structurally NaCl net-importer (~85% of demand imported). Major source markets: Australia (Cheetham Salt premium solar-evaporation, ~40% of Korean imports), China (Qinghai Salt Lake Industry + Shandong Sea Salt, ~25%), India (Gujarat solar-evaporation, ~15%), Mexico (Guerrero Negro, ~10%). Korean chlor-alkali consumers (LG Chem Yeosu, Hanwha Solutions Yeosu, Lotte Chemical Yeosu, OCI Chemical Pohang) drive captive salt demand. KCFTA preferential zero-duty makes Chinese-origin competitive vs Australian (free under KAFTA), Indian, and Mexican alternatives.

Required documents

  • K-REACH registration number on Korean side (registrant or OR-appointed)
  • Korean Customs Service (KCS) declaration with HS code 2501
  • China-Korea FTA Form CO certificate of origin for preferential treatment
  • Industrial-grade specification certificate OR food-grade specification certificate
  • KFDA Food Codex conformity declaration for food-grade lots

Common compliance traps

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

  • **Lightest K-REACH-side regulatory profile in the dataset**: no TCCA, no Drug Management Act, no CAPP, no MSDS
  • **Korea is structurally NaCl net-importer**: ~85% of Korean salt demand is imported. Domestic production limited to Sinanseom solar-evaporation Jeolla-do + Jeju Island secondary
  • Major source markets for Korean salt imports: Australia (Cheetham Salt, ~40%), China (Qinghai Salt Lake + Shandong Sea Salt, ~25%), India (Gujarat solar-evaporation, ~15%), Mexico (Guerrero Negro, ~10%)
  • Korean chlor-alkali consumers drive captive demand: LG Chem Yeosu, Hanwha Solutions Yeosu, Lotte Chemical Yeosu, OCI Chemical Pohang
  • KCFTA preferential zero-duty makes Chinese-origin competitive but Australian (under KAFTA) and Indian (under CEPA) also enjoy preferential or zero rates
  • No active Korean AD/CVD case on Chinese sodium chloride
  • KFDA Food Codex applies for food-grade lots; lighter than EU and US food-import regulation
