Adipic acid (hexanedioic acid) under IECSC
C6H10O4 · 己二酸
Status: Listed. Adipic acid is on the IECSC public portion as a foundational nylon 6,6 chain monomer. New-substance notification under MEE Decree No. 7 (2010) is NOT required. **Adipic acid is NOT on China's Catalog of Hazardous Chemicals at standard industrial-grade level** (light hazard, no GHS DG transport classification). NOT on Highly Toxic Chemicals Catalog. NOT on Easily-Made Drugs Catalog. **13% China VAT export rebate** for adipic acid (HS 291712) per current organic chemicals chapter rebate schedule (verify before invoicing against the most recent MOF / GACC rebate notice). China dominates global capacity (verify percent-of-global share against ICIS or S&P Commodity Insights before quoting; prior industry reports cited ~60 percent at ~6 Mt/yr) led by Pingmei Shenma (Henan), Liaoning Hualu (Liaoning), Hongbai Group (Shandong), Hualu-Hengsheng (Shandong), Hubei Yihua (Hubei) (verify each producer-site pair against the producer's public website before relying on a specific plant).
Adipic acid is comfortably IECSC-listed with **light IECSC-side regulatory profile** alongside sodium chloride batch 16 plus glycerol batch 35 plus sodium carbonate batch 36 plus potassium chloride batch 44. NOT on Catalog of Hazardous Chemicals at standard industrial-grade. **13% China VAT export rebate**. China dominates global capacity led by Pingmei Shenma, Liaoning Hualu, Hongbai Group, Hualu-Hengsheng, Hubei Yihua. Production: cyclohexane plus nitric acid batch 40 two-step oxidation (~95 percent globally). N2O emissions from older non-abated Chinese plants are at increasing policy risk. **Nylon 6,6 chain primary downstream** (~70 percent of demand combined with HMDA hexamethylenediamine).

Classifications under this regime
- Listed on IECSC
- NOT on China's Catalog of Hazardous Chemicals at standard industrial-grade level
- NOT on China's Highly Toxic Chemicals Catalog
- NOT on the Easily-Made Drugs Precursor Chemicals Catalog
- GB/T 13252-2008 specification applies for industrial-grade adipic acid (Chinese national standard; verify against the current version at https://www.codeofchina.com/ before relying)
- GB/T 17519-2013 Chinese-language SDS standard applies (effective 31 January 2014, references UN GHS 4th revised edition; verify against the current version at https://www.codeofchina.com/standard/GBT17519-2013.html)
- GACC export classification: HS 291712 (adipic acid)
- GB 6944-2012 dangerous-goods transport classification: not regulated as DG
Restrictions and conditions of use
- NO Hazardous Chemicals Operation Permit required (light hazard)
- NO Hazardous Chemicals Road Transport Permit required
- **13% China VAT export rebate** for adipic acid (HS 291712); verify before invoicing
- GB/T 17519 Chinese-language SDS NOT specifically required for non-hazardous lots but commonly provided
- MEE policy on adipic-acid producer N2O emissions: Chinese producers under increasing scrutiny for N2O abatement under domestic emissions controls (verify the current Chinese ETS or N2O abatement requirement against MEE policy notices before relying)
Importer obligations
For Chinese-origin adipic acid exported abroad, no IECSC obligation falls on the foreign importer. Light-regulatory profile. Major Chinese producers: Pingmei Shenma (Henan), Liaoning Hualu (Liaoning), Hongbai Group (Shandong), Hualu-Hengsheng (Shandong), Hubei Yihua (Hubei). **Pingmei Shenma is the largest single-company Chinese adipic-acid producer (verify the most recent capacity ranking against the Pingmei Shenma corporate site or ICIS before quoting world-largest rank)**.
Required documents
- GACC export declaration with HS code 291712
- Industrial-grade certificate per GB/T 13252-2008
- GHS-compliant SDS in Simplified Chinese per GB/T 17519-2013 (commonly provided though not specifically required for non-hazardous lots)
- Standard commercial invoice and packing list
- Certificate of analysis for grade specification
- 13% VAT rebate filing documentation per current MOF / GACC schedule
Common compliance traps
The pitfalls that have bitten importers on this lane in the past. None of these is theoretical.
- **Light IECSC-side regulatory profile** alongside sodium chloride batch 16 plus glycerol batch 35 plus sodium carbonate batch 36 plus potassium chloride batch 44
- **13% China VAT export rebate** is structural margin support for Chinese exporters
- Major Chinese producers: Pingmei Shenma (Henan), Liaoning Hualu (Liaoning), Hongbai Group (Shandong), Hualu-Hengsheng (Shandong), Hubei Yihua (Hubei)
- Production: cyclohexane oxidation to KA oil plus nitric acid batch 40 oxidation (~95 percent globally)
- **N2O emissions** from Chinese adipic-acid plants are increasingly regulated; older non-abated capacity has higher Scope 1 footprint and is at policy risk
- **Nylon 6,6 chain primary downstream** (~70 percent of demand combined with HMDA): Chinese demand growth drives capacity additions

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.
