Sodium sulfate (Glauber's salt) under IECSC
Na2SO4 · 硫酸钠
Status: Listed. Sodium sulfate 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 sodium sulfate (HS 283311 / 283319) per current inorganic chemicals chapter rebate schedule (verify the rate against the most recent MOF / GACC rebate notice before invoicing). **China dominates global sodium sulfate capacity (verify percent-of-global share against ICIS or USGS Mineral Commodity Summaries before quoting), producing both natural sodium sulfate from mirabilite + saline-lake brine evaporation (Sichuan Hongya region + Inner Mongolia Lanyu + Qinghai Saline Lake + Xinjiang Eight One) and synthetic sodium sulfate as by-product of rayon / viscose process plus Mannheim sulfate process plus KCl + H2SO4 process plus chemical industry brine-acid neutralisation streams**. Major Chinese producers: Sichuan Hongya Qingyijiang natural sodium sulfate, Inner Mongolia Lanyu Petroleum Chemical natural sodium sulfate, Qinghai Saline Lake Industry natural sodium sulfate, Xinjiang Eight One natural sodium sulfate, Jiangsu Sailboat Chemical synthetic sodium sulfate (rayon by-product), Sichuan Yibin Tianyuan Chemical synthetic sodium sulfate (verify each producer-site pair against the producer's public website before relying on a specific plant).
Sodium sulfate 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). China dominates global sodium sulfate capacity (saline-lake belts + rayon-by-product synthetic). Production: natural and synthetic streams both significant.
Listing and threshold
| Substance | Sodium sulfate (Glauber's salt) (CAS 7757-82-6), Na2SO4 |
|---|---|
| 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/T 6009-2014 industrial sodium sulfate specification (verify the current sodium-sulfate-specific GB / GB-T standard at https://www.codeofchina.com/ before relying)
- GB/T 17519-2013 Chinese SDS standard
- GACC HS code: 283311 (anhydrous) or 283319 (other including Glauber's salt decahydrate)
- GB 6944-2012 transport: NOT regulated
- **Pharma-grade compliance with Chinese Pharmacopoeia (ChP)** where placed as pharma-grade Glauber's salt laxative (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 chemicals chapter schedule (verify against the most recent MOF / GACC rebate notice before invoicing)
- GB/T 17519 Chinese SDS required
Importer obligations
For Chinese-origin sodium sulfate exported abroad, no IECSC obligation falls on the foreign importer. Major Chinese producers concentrated in saline-lake belts (Sichuan Hongya + Inner Mongolia Lanyu + Qinghai Saline Lake + Xinjiang Eight One) plus rayon-by-product synthetic streams (Jiangsu Sailboat + Sichuan Yibin Tianyuan).
Required documents
- GACC export declaration HS 283311 or 283319
- GHS Chinese SDS per GB/T 17519
- 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: Sichuan Hongya Qingyijiang, Inner Mongolia Lanyu Petroleum Chemical, Qinghai Saline Lake Industry, Xinjiang Eight One (natural saline-lake), Jiangsu Sailboat Chemical, Sichuan Yibin Tianyuan Chemical (synthetic rayon-by-product) (verify each producer-site pair)
- Production: natural (mirabilite + saline-lake brine, China-dominant) and synthetic (rayon by-product + Mannheim sulfate + KCl + H2SO4 + brine acid-soda by-product)
- **Pulp / paper Kraft chemical recovery + detergent + glass + textile dyeing + tanning + laxative + heat-storage downstream chains** dominate Chinese consumption

Glossary
IECSC, Inventory of Existing Chemical Substances in China
The Chinese national chemical inventory listing substances legally manufactured, imported, used, or sold in China before 2003. A substance not on IECSC requires a New Chemical Substance Notification (NCSN) under MEE Order 12 before it can be manufactured or imported into China. Functionally similar to TSCA in the US and REACH in the EU but with distinct procedural requirements.
