C2H4Cl2 · 1,2-二氯乙烷

Status: Registered. EDC is fully registered under REACH at the highest tonnage band (>1,000,000 tonnes/year). **Distinguishing pattern: VCM batch 70 (vinyl chloride monomer) primary downstream chain (~95 percent of EDC demand globally; via thermal cracking of EDC) + ethylene + chlor-alkali batch 45 chlorine direct addition route (~99 percent globally) + Carc 1B (H350) plus IARC Group 2B + Flam. Liq. 2 + closes ethylene plus chlor-alkali batch 45 chain to PVC batch 10 polymer (NEW combined).** Reg (EC) 1272/2008 harmonised: Carc 1B (H350) plus Flam. Liq. 2 (H225) plus Acute Tox. 4 oral (H302) plus Skin Irrit. 2 (H315) plus Eye Irrit. 2 (H319) plus STOT SE 3 (H335). REACH SVHC candidate list: prior reports flag EDC added 19 December 2011 (carc) (verify against https://echa.europa.eu/candidate-list-table). REACH Annex XIV (Authorisation List): prior reports flag inclusion via Reg (EU) 348/2013 with sunset 22 November 2017 for non-intermediate use; bulk VCM-precursor intermediate use exempt under Art. 2(8)(b) (verify against https://echa.europa.eu/authorisation-list and EUR-Lex Reg 348/2013). NO active EU AD case on Chinese-origin EDC currently (verify against EUR-Lex https://eur-lex.europa.eu/ before invoicing).

EDC is fully REACH-registered with **Carc 1B + Flam. Liq. 2 + Acute Tox. 4 oral + IARC Group 2B**. **VCM batch 70 (vinyl chloride monomer) primary downstream chain** dominates (~95 percent of EDC demand globally).

NO active EU AD case. Major Chinese producers: chlor-alkali batch 45 multi-site (Sinopec, Wanhua, Hengli, Tangshan Sanyou, Shandong Haihua), Juhua Group, Dongyue Group. Production: ethylene + chlor-alkali chlorine direct addition (~99 percent globally). **Closes ethylene + chlor-alkali batch 45 chain to PVC batch 10**.

Listing and threshold

Substance 1,2-Dichloroethane (EDC, ethylene dichloride) (CAS 107-06-2), C2H4Cl2
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

  • Harmonised CLP 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
  • **IARC: Group 2B (possibly carcinogenic to humans) per IARC Monograph 71** (verify Volume 71 against https://monographs.iarc.who.int/list-of-classifications)
  • NOT subject to Drug Precursors or Explosives Precursors scheduling
  • ADR / RID transport classification: Class 6.1 (toxic substance) and Class 3 (flammable liquid; primary risk subsidiary), UN 1184 (ethylene dichloride), Packing Group II

Restrictions and conditions of use

  • Annex XIV (REACH Authorisation List) status: prior reports flag EDC inclusion via the Authorisation List Reg (EU) 348/2013 with sunset 22 November 2017 for non-intermediate use (verify against ECHA https://echa.europa.eu/authorisation-list and EUR-Lex Reg 348/2013 https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32013R0348 before invoicing; bulk VCM-precursor intermediate use is exempt under REACH Art. 2(8)(b))
  • SVHC candidate list status: prior reports flag EDC added to the REACH SVHC candidate list on 19 December 2011 (carc) (verify against ECHA https://echa.europa.eu/candidate-list-table before invoicing)
  • NOT subject to any Annex XVII restriction at standard industrial-grade level
  • EU Directive 2004/37/EC Carcinogens and Mutagens at Work: occupational exposure limit applies (verify current OEL value against https://eur-lex.europa.eu/eli/dir/2004/37/oj before relying)
  • NO active EU AD case on Chinese-origin EDC currently
  • 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). EDC is structurally captive within integrated VCM-PVC plants in most cases (>95 percent of demand is captive). Major Chinese producers: chlor-alkali batch 45 multi-site (Sinopec, Wanhua, Hengli), Tangshan Sanyou, Shandong Haihua, Juhua Group, Dongyue 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 reflecting H225 / H302 / H315 / H319 / H335 / H350 classification
  • CLP labelling with GHS02 + GHS07 + GHS08 + DANGER
  • Customs entry HS code 290315 (1,2-dichloroethane)
  • ADR consignment note Class 6.1 + Class 3, UN 1184, PG II
  • **EU Directive 2004/37/EC Carcinogens and Mutagens at Work compliance documentation**

Common compliance traps

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

  • **VCM batch 70 (vinyl chloride monomer) primary downstream chain** (~95 percent of EDC demand globally) is structurally dominant
  • Carc 1B + IARC Group 2B drives substantial workplace surveillance
  • REACH SVHC candidate list: prior reports flag EDC added 19 December 2011 (carc); Annex XIV (Authorisation List) prior reports flag inclusion via Reg (EU) 348/2013 with sunset 22 November 2017 for non-intermediate use; bulk VCM-precursor intermediate use exempt under Art. 2(8)(b) (verify against https://echa.europa.eu/candidate-list-table and https://echa.europa.eu/authorisation-list)
  • NO active EU AD case on Chinese EDC currently
  • NOT in CBAM Phase 1
  • Major Chinese producers: chlor-alkali batch 45 multi-site (Sinopec + Wanhua + Hengli + Tangshan Sanyou + Shandong Haihua), Juhua Group, Dongyue Group; China dominates global EDC capacity (verify percent-of-global share against ICIS or S&P Commodity Insights before quoting; prior reports cited approximately 50 percent at ~25 to 30 Mt/yr)
  • Production: ethylene + chlor-alkali batch 45 chlorine direct addition (~99 percent globally; Cl2 + C2H4 → C2H4Cl2)
  • **Closes ethylene + chlor-alkali batch 45 chain to PVC batch 10**: EDC → VCM batch 70 → PVC batch 10
