CAS 107-06-2 · K-REACH · Republic of Korea

1,2-Dichloroethane (EDC, ethylene dichloride) under K-REACH

C2H4Cl2 · 1,2-二氯乙烷

Status: Registered. EDC is registered under K-REACH and listed as a Priority Existing Chemical (PEC). **EDC IS on Korea TCCA Toxic Chemicals list** (Carc 1B harmonised classification): TCCA Toxic Chemicals Handling Permit at destination facility required. NOT on Korean Drug Management Act precursor list. NO active Korean AD/CVD case on Chinese-origin EDC. Korea has substantial domestic EDC production (LG Chem, Hanwha Solutions, Lotte Chemical chlor-alkali integrated VCM-PVC capacity); structurally balanced. KCFTA preferential zero-duty applies for Chinese-origin imports.

K-REACH treats EDC as a routine PEC-registered substance but **TCCA Toxic Chemicals Handling Permit at destination facility is the dominant practitioner overhead**. Korea has substantial domestic EDC production at chlor-alkali integrated VCM-PVC complexes. **EDC distinguishing pattern across all 5 regimes**: VCM batch 70 primary downstream chain (~95 percent of EDC demand globally; via thermal cracking) + ethylene + chlor-alkali batch 45 chlorine direct addition route (~99 percent globally) + Carc 1B (H350) + IARC Group 2B per Monograph 71 (1999) reaffirmed Monograph 110 (2017) (verify against https://monographs.iarc.who.int/list-of-classifications) + Cal Prop 65 carcinogen 1 October 1987 + OSHA PEL 50 ppm Table Z-2 + EPA TSCA Section 6 high-priority designation + Korea TCCA Toxic Chemicals + 0% China VAT export rebate + closes ethylene + chlor-alkali chain to PVC batch 10.

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: Carc. 1B (H350), Flam. Liq. 2 (H225), Acute Tox. 4 oral (H302), Skin Irrit. 2 (H315), Eye Irrit. 2 (H319), STOT SE 3 (H335)
  • Signal word: DANGER. GHS pictograms: GHS02 + GHS07 + GHS08
  • KOSHA workplace exposure standard: 10 ppm 8-hr TWA
  • **Listed in Korea TCCA Toxic Chemicals list**
  • NOT on Korean Drug Management Act precursor list
  • Korean Customs Service (KCS) HS code: 290315
  • **IARC: Group 2B per IARC Monograph 71 (1999); reaffirmed per Monograph 110 (2017)** (verify against https://monographs.iarc.who.int/list-of-classifications)

Restrictions and conditions of use

  • **TCCA Toxic Chemicals Handling Permit at destination facility required**
  • Chemical Accident Prevention Plan (CAPP) may be required
  • KOSHA MSDS in Korean required at workplace
  • NO active Korean AD/CVD case on Chinese EDC currently
  • KCFTA preferential zero-duty applies (HS 290315)
  • Female-of-child-bearing-age workplace protection planning for Carc 1B

Importer obligations

Korean importer of record must hold K-REACH registration. **TCCA Toxic Chemicals Handling Permit at destination facility is the dominant practitioner-facing overhead**. Korea has substantial domestic EDC production at chlor-alkali integrated VCM-PVC complexes.

Required documents

  • K-REACH registration number on Korean side
  • Korean MSDS reflecting H225 / H302 / H315 / H319 / H335 / H350
  • KCS declaration with HS 290315
  • **TCCA Toxic Chemicals Handling Permit** at destination facility
  • China-Korea FTA Form CO

Common compliance traps

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

  • **TCCA Toxic Chemicals Handling Permit at destination facility is the dominant practitioner overhead**
  • Carc 1B + IARC Group 2B drives long-term workplace surveillance
  • KCFTA preferential zero-duty applies
  • NO active Korean AD/CVD case on Chinese EDC
  • Korean female-of-child-bearing-age workplace protection planning for Carc 1B
