Zinc metal (Zn) under REACH

Zn · 锌

Status: Registered. Zinc metal is fully registered under REACH. **Distinguishing pattern: LME (London Metal Exchange) Special High Grade Zinc (SHG, ≥99.995% Zn) is the global benchmark contract; primary mine production via flotation concentration of zinc-lead sulphide ore (sphalerite ZnS) plus secondary production via zinc-scrap + galvaniser-EAF-dust recycling (~30% of global supply); pyrometallurgical Imperial Smelting Furnace (ISF) and dominant electrolytic refining (RLE = roast-leach-electrowinning) yield refined SHG zinc. Downstream consumption split: galvanising / hot-dip + continuous-galvanising-line ~50% (corrosion-protection of automotive + construction steel) + die-casting alloys (Zamak / ZA family) ~17% + brass + bronze ~17% + chemicals (zinc oxide + zinc sulphate + zinc chloride) ~6% + battery (alkaline + Zn-air primary cells) ~16%. Major non-EU producers: Korea Zinc (Onsan Ulsan smelter, world's largest single-site zinc smelter), Nyrstar (Belgium Balen + Netherlands Budel + Australia Hobart TAS + Port Pirie SA + USA Clarksville TN), Boliden (Sweden Ronnskar + Finland Kokkola + Ireland Tara Mines), Hindustan Zinc (India Zawar + Rampura Agucha + Sindesar Khurd Rajasthan), Teck Resources (Canada Trail BC + Red Dog Alaska USA), Glencore (Switzerland trader + integrated mines + smelters across Australia + Canada + Kazakhstan + Peru), MMG (Australia Dugald River QLD + Las Bambas Peru). Major Chinese producers (China is the world's largest zinc refiner ~45% global share): Zhuzhou Smelter Group (Hunan Zhuzhou) + Yunnan Chihong Zinc Germanium (Yunnan Qujing) + Hechi Nanfang Nonferrous (Guangxi) + Liuzhou China Tin (Guangxi) + Shaanxi Dongling Zinc Industry (Baoji) + Bayannur Zijin Wuxin (Inner Mongolia); verify each producer-site pair against the producer's public website before relying.** NOT SVHC. NOT Annex XIV. **EU AD measures on Chinese-origin zinc PRODUCTS (notably continuous galvanised steel sheet under various Reg numbers including Reg (EU) 2017/1444 + successor measures) exist** (verify exact current measures per case + per producer against EUR-Lex https://eur-lex.europa.eu/ before invoicing). NOT in CBAM Phase 1 scope (CBAM covers iron / steel + aluminium, NOT zinc).

Zinc metal is fully REACH-registered. NOT SVHC, NOT Annex XIV; Aquatic Acute 1 + Chronic 1 in particulate / powder form. **LME Special High Grade Zinc (SHG, ≥99.995% Zn) is the global benchmark contract**. **EU AD measures on Chinese-origin zinc PRODUCTS (notably continuous galvanised steel sheet); verify per case + per producer at EUR-Lex before invoicing**. NOT in CBAM Phase 1 scope. **~50% galvanising + ~17% die-cast + ~17% brass + ~16% battery + ~6% chemicals downstream**. **AD/CVD on downstream galvanised steel is the practical EU-import compliance pivot.**

Listing and threshold

Substance Zinc metal (Zn) (CAS 7440-66-6), Zn
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 (massive metal-form exemptions may apply; verify against ECHA guidance for substances in massive form)

Classifications under this regime

  • Aquatic Acute 1 + Aquatic Chronic 1: H400 + H410 in particulate / powder form per harmonised CLP (verify exact harmonised classification including massive-form exemption against ECHA Annex VI to CLP Table 3.1 before relying)
  • Pyrophoric Liquid 2 + Self-heating Solid 1 may apply to zinc dust + zinc powder (specific particle-size + condition dependent; verify against ECHA Annex VI)
  • IARC: Not classified (verify against https://monographs.iarc.who.int/ before relying)
  • ADR / RID: ZINC POWDER UN 1383 Class 4.2 PG II + UN 1436 ZINC RESINATE Class 4.1 PG III + UN 1435 ZINC ASHES Class 4.3 PG III may apply at specific particle-size + form (verify against current ADR at https://unece.org/transport/dangerous-goods/adr-2025-files before consigning); massive zinc metal NOT regulated
  • **LME Special High Grade Zinc contract: SHG specification ≥99.995% Zn** (verify against https://www.lme.com/ for current contract specification)
  • **EU AD measures on Chinese-origin zinc PRODUCTS (notably continuous galvanised steel sheet)** exist (verify exact current measures per case + per producer against EUR-Lex https://eur-lex.europa.eu/ before invoicing)

Restrictions and conditions of use

Importer obligations

A non-EU producer cannot register directly under REACH for zinc substance. The EU importer of record must hold a registration or rely on an Only Representative (OR). **AD/CVD scope determination per downstream zinc-coated steel product per case + per producer at EUR-Lex.** Major non-EU producers: Korea Zinc (Onsan Ulsan smelter), Nyrstar (Australia Hobart TAS + Port Pirie SA + USA Clarksville TN + Belgium Balen + Netherlands Budel), Hindustan Zinc (India), Teck Resources (Canada Trail BC + Alaska Red Dog), Glencore (integrated mines + smelters), MMG (Australia + Peru). Major Chinese producers: Zhuzhou Smelter Group (Hunan Zhuzhou) + Yunnan Chihong (Yunnan Qujing) + Hechi Nanfang (Guangxi) + Liuzhou China Tin (Guangxi) + Shaanxi Dongling Zinc (Baoji) + Bayannur Zijin Wuxin (Inner Mongolia).

Required documents

  • REACH registration number on EU side (or massive-form exemption documentation)
  • SDS (Aquatic Acute 1 + Aquatic Chronic 1 in particulate / powder form; pyrophoric / self-heating where dust)
  • Customs entry HS code 7901 (unwrought zinc) / 7902 (waste + scrap) / 7903-7907 (downstream products)
  • ADR transport documentation UN 1383 / UN 1435 / UN 1436 where consigned in zinc powder / dust / ash form
