Calcium carbonate (GCC / PCC / limestone) under IECSC

CaCO3 · 碳酸钙

Status: Listed. Calcium carbonate is on the IECSC public portion. **NOT on China's Catalog of Hazardous Chemicals at industrial-grade purity** (verify against the most recent MEE Catalog of Hazardous Chemicals before relying; low hazard profile beyond particulate dust). NOT on Highly Toxic Chemicals Catalog. NOT on Easily-Made Drugs Catalog. **China VAT export rebate** for calcium carbonate (HS 251710 / 283650) per current inorganic / mineral chemicals chapter rebate schedule (verify the rate against the most recent MOF / GACC rebate notice before invoicing). China dominates global GCC capacity from Guangxi Hezhou region (regional GCC capital), Anhui Chizhou region, Jiangxi, Zhejiang Jiande quarries (verify percent-of-global share against ICIS or S&P Commodity Insights before quoting). Major Chinese GCC and PCC producers: Guangxi Hezhou region GCC quarries, Anhui Chizhou region GCC quarries, Jiangxi PCC plants, Zhejiang Jiande GCC quarries, Shandong Sanli Calcium Carbonate, Hebei Jingye Calcium Carbonate (verify each producer-site pair against the producer's public website before relying on a specific plant).

Calcium carbonate is comfortably IECSC-listed; typically NOT on Catalog of Hazardous Chemicals at industrial grade. NOT on Highly Toxic, NOT on Easily-Made Drugs. **China VAT export rebate** rate per current schedule (verify before invoicing). **Food-grade GB 1886.214-2016 plus ChP for pharma-grade**. China dominates global GCC capacity led by Guangxi Hezhou region. Production: GCC dominant; PCC for high-purity grades.

Listing and threshold

Substance Calcium carbonate (GCC / PCC / limestone) (CAS 471-34-1), CaCO3
Regime China Inventory of Existing Chemical Substances (IECSC), administered by the Ministry of Ecology and Environment (MEE)
Jurisdiction People's Republic of China
Status Listed
Tonnage threshold No new-substance threshold. Hazardous Chemicals Operation Permit not typically required

Classifications under this regime

  • NOT typically on Catalog of Hazardous Chemicals at industrial-grade purity (verify against the most recent MEE Catalog before relying)
  • NOT on Highly Toxic Chemicals Catalog
  • NOT on Easily-Made Drugs Catalog
  • GB 1886.214-2016 food-grade GCC specification (verify the current calcium-carbonate-specific GB / GB-T standard at https://www.codeofchina.com/ before relying)
  • GB/T 17519-2013 Chinese SDS standard
  • GACC HS code: 251710 (limestone) or 283650 (calcium carbonate)
  • GB 6944-2012 transport: NOT regulated
  • **Pharma-grade compliance with Chinese Pharmacopoeia (ChP)** where placed as pharma-grade calcium carbonate antacid (verify monograph reference against the most recent ChP edition before relying)

Restrictions and conditions of use

  • Hazardous Chemicals Operation Permit not typically required (verify against the most recent MEE Catalog before relying)
  • **China VAT export rebate** rate per current inorganic / mineral chemicals chapter schedule (verify against the most recent MOF / GACC rebate notice before invoicing)
  • GB/T 17519 Chinese SDS required
  • **Food-grade GB 1886.214-2016** specification compliance for E170 use

Importer obligations

For Chinese-origin calcium carbonate exported abroad, no IECSC obligation falls on the foreign importer. Major Chinese producers: Guangxi Hezhou region GCC quarries, Anhui Chizhou region GCC quarries, Jiangxi PCC plants, Zhejiang Jiande GCC quarries, Shandong Sanli Calcium Carbonate, Hebei Jingye Calcium Carbonate.

Required documents

  • GACC export declaration HS 251710 or 283650
  • GHS Chinese SDS per GB/T 17519
  • Food-grade GB 1886.214-2016 certification where applicable
  • Pharma-grade ChP certification where applicable

Common compliance traps

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

  • Catalog of Hazardous Chemicals status (verify against the most recent MEE Catalog before relying)
  • **China VAT export rebate** rate (verify against the most recent MOF / GACC rebate notice before invoicing)
  • NOT on Highly Toxic, NOT on Easily-Made Drugs
  • Major Chinese producers: Guangxi Hezhou region, Anhui Chizhou region, Jiangxi, Zhejiang Jiande, Shandong Sanli, Hebei Jingye (verify each producer-site pair)
  • Production: GCC (limestone quarry plus mill) dominant; PCC (Ca(OH)2 plus CO2 carbonation) for high-purity / fine-particle grades
  • **Paper plus paint / coating plus plastics plus rubber plus cement plus FGD plus food-grade E170 plus pharma antacid downstream chains** dominate Chinese consumption
