Zinc metal (Zn) under IECSC

Zn · 锌

Status: Listed. Zinc metal is on IECSC as an existing chemical. **China is the world's largest zinc refiner (~45% global share)** with major capacity: 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. Subject to **multiple US + EU + Canadian AD/CVD measures on Chinese-origin downstream zinc-coated steel PRODUCTS (corrosion-resistant + galvanised + galvalume + galvanneal)** (verify per case + per producer at access.trade.gov + EUR-Lex + Canada Border Services Agency before invoicing). NOT on China Hazardous Chemicals Catalogue (2015 edition) at refined Zn level (verify against https://www.mem.gov.cn/ before relying); zinc powder + zinc dust may be Hazardous Chemicals Catalogue listed (verify form-specific status). **China VAT export rebate on zinc products has historically varied by tariff line + period; verify current VAT rebate rate per HS line against current SAT / MOFCOM circulars before invoicing**.

IECSC treats zinc metal as a routine listed existing chemical at refined Zn level (zinc powder + zinc dust may carry hazardous-chemicals listing). **China is the world's largest zinc refiner (~45% global share)**. Major Chinese producers: Zhuzhou Smelter Group + Yunnan Chihong + Hechi Nanfang + Liuzhou China Tin + Shaanxi Dongling + Bayannur Zijin Wuxin. **Subject to multiple US + EU + Canadian AD/CVD measures on Chinese-origin downstream zinc-coated steel PRODUCTS; verify per case + per producer at access.trade.gov + EUR-Lex + CBSA before invoicing**. **AD/CVD on downstream galvanised steel is the practical Chinese-origin export compliance pivot.**

Listing and threshold

Substance Zinc metal (Zn) (CAS 7440-66-6), Zn
Regime China Inventory of Existing Chemical Substances (IECSC), administered by Ministry of Ecology and Environment (MEE)
Jurisdiction People's Republic of China
Status Listed
Tonnage threshold New Chemical Substance Notification (NCSN) under MEE Decree 12 not required (existing chemical)

Classifications under this regime

  • IECSC Listed Existing Chemical
  • GB 30000 GHS classification: Aquatic Acute 1 + Aquatic Chronic 1 in particulate / powder form; zinc powder may carry pyrophoric / self-heating classification (verify against current GB 30000-series at http://www.csres.com/ + http://www.std.samr.gov.cn/ before relying)
  • NOT on China Hazardous Chemicals Catalogue (2015 edition) at refined Zn level (zinc powder + zinc dust may be listed; verify form-specific status against https://www.mem.gov.cn/ before relying)
  • JT/T 617 / GB 12268 hazardous-goods transport: UN 1383 Class 4.2 PG II for zinc powder / dust; massive zinc metal NOT regulated (verify against current GB 12268 + JT/T 617 dangerous-goods transport regulations at http://www.std.samr.gov.cn/ + http://www.mot.gov.cn/ before consigning)
  • **SHFE Shanghai Futures Exchange Zinc contract** (Chinese benchmark alongside LME SHG; verify against https://www.shfe.com.cn/ for current contract specification)
  • **China VAT export rebate on zinc products has historically varied (verify per HS line + current SAT / MOFCOM circulars before invoicing)**
  • IARC: Not classified (verify against https://monographs.iarc.who.int/ before relying)

Restrictions and conditions of use

  • GB 30000 GHS labelling required
  • Customs HS 7901 (unwrought zinc) / 7902 (waste + scrap) / 7903-7907 (downstream products)
  • No CBAM equivalent in Chinese domestic regulation
  • **Subject to multiple US + EU + Canadian AD/CVD measures on Chinese-origin downstream zinc-coated steel PRODUCTS; verify per case + per producer + per HS line at https://access.trade.gov/ + EUR-Lex + Canada Border Services Agency before invoicing**
  • Chinese zinc-scrap import restrictions tightened post-2017 (Operation National Sword + 2018 Solid Waste Management Action Plan); verify current import-license + quality-grade requirements against https://www.mee.gov.cn/ before relying

Importer obligations

Chinese importer of record must hold IECSC listing reliance. **China is the world's largest zinc refiner; export consignment of downstream zinc-coated steel products triggers AD/CVD scope determination per case + per producer at destination.** Concentrate inbound: major sources Australia (MMG Dugald River QLD + Glencore Mount Isa QLD + South32 Cannington QLD), Peru (Volcan + Glencore Antamina + Compania Minera Milpo), Mexico (Industrias Penoles + Newmont), Bolivia, Iran, Kazakhstan; zinc-scrap inbound subject to post-2017 import-license + quality-grade restrictions per MEE Solid Waste Management Action Plan.

Required documents

  • GB-compliant SDS in Chinese (Aquatic Acute 1 + Aquatic Chronic 1 in particulate / powder form; pyrophoric / self-heating where dust)
  • China Customs (CCS) declaration HS 7901 / 7902 / 7903-7907
  • GB hazardous-goods transport documentation UN 1383 Class 4.2 PG II for zinc powder / dust
  • Concentrate inbound: applicable inbound documentation per Chinese inspection regime (CIQ)
  • Zinc-scrap inbound: import-license + quality-grade documentation per MEE Solid Waste Management Action Plan
  • **Downstream-product outbound: AD/CVD documentation per destination case + per producer (verify against https://access.trade.gov/ + EUR-Lex + CBSA per case)**
  • SHFE warehouse warrant where contract delivery

Common compliance traps

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

  • **China is the world's largest zinc refiner (~45% global share)**; major Chinese producers Zhuzhou Smelter Group + Yunnan Chihong + Hechi Nanfang + Liuzhou China Tin + Shaanxi Dongling + Bayannur Zijin Wuxin
  • **Subject to multiple US + EU + Canadian AD/CVD measures on Chinese-origin downstream zinc-coated steel PRODUCTS (verify per case + per producer at access.trade.gov + EUR-Lex + CBSA)**
  • **Section 232 US steel tariffs (25%, March 2018) apply to galvanised steel imports as steel derivatives**
  • GB 30000 GHS classification (Aquatic Acute 1 + Chronic 1 in particulate / powder form)
  • UN 1383 Class 4.2 PG II for zinc powder / dust; massive metal NOT regulated
  • **~50% galvanising + ~17% die-cast + ~17% brass + ~16% battery + ~6% chemicals downstream**
  • Chinese zinc-scrap import restrictions tightened post-2017 (Operation National Sword)
