Nylon-6 (polycaprolactam, polyamide-6) under IECSC
(C6H11NO)n · 尼龙-6 / 聚己内酰胺
Status: Listed. Nylon-6 is on the IECSC public portion. NOT on China's Catalog of Hazardous Chemicals (polymer light-hazard). NOT on Highly Toxic Chemicals Catalog. NOT on Easily-Made Drugs Catalog. **0% China VAT export rebate** for nylon-6 (verify the current export-rebate schedule against the State Taxation Administration before invoicing). China is a dominant global nylon-6 producer led by Sinopec Baling + Sinopec Shijiazhuang + Hengyi Petrochemical + Tianlong + Lujian Caprolactam + Yangmei Coal Industry-Hengtian + Fujian Shenyuan + Hubei Sanning (same producers as caprolactam batch 14, integrated upstream + downstream chain; verify each producer-site pair against the company corporate site before relying, and verify percent-of-global capacity share and Mt/yr nameplate against ICIS or S&P Commodity Insights before quoting). Capacity additions 2024-2026 at Sinopec Baling Phase 2 + Hengyi Phase 2 + Tianlong + Yangmei-Hengtian + Fujian Shenyuan extend Chinese capacity dominance (verify the most recent Phase 2 nameplate and commissioning year against the producer corporate sites or ICIS before quoting).
Nylon-6 is comfortably IECSC-listed with **light IECSC-side regulatory profile**: NOT on Catalog of Hazardous Chemicals, NOT on Highly Toxic, NOT on Easily-Made Drugs. **0% China VAT export rebate** for nylon-6 (verify the current export-rebate schedule against the State Taxation Administration before invoicing). China is a dominant global nylon-6 producer (verify the current percent-of-global capacity share and Mt/yr nameplate against ICIS or S&P Commodity Insights before quoting) led by same producers as caprolactam batch 14 (Sinopec Baling + Shijiazhuang + Hengyi + Tianlong + Lujian + Yangmei-Hengtian + Fujian Shenyuan + Hubei Sanning), integrated upstream caprolactam + downstream nylon-6 chain. EU trade-defence status on Chinese-origin nylon-6 unverified at audit (verify current measure status against EUR-Lex https://eur-lex.europa.eu/ before invoicing).
Listing and threshold
| Substance | Nylon-6 (polycaprolactam, polyamide-6) (CAS 25038-54-4), (C6H11NO)n |
|---|---|
| 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 applies. Hazardous Chemicals Operation Permit NOT required (polymer light-hazard) |
Classifications under this regime
- Listed on IECSC
- NOT on China's Catalog of Hazardous Chemicals
- NOT on China's Highly Toxic Chemicals Catalog
- NOT on the Easily-Made Drugs Precursor Chemicals Catalog
- GB/T 17931 specification applies for industrial-grade nylon-6 chip (Chinese national standard)
- GACC export classification: HS 39081000 (nylon-6 primary form)
- China dominates global nylon-6 capacity (~70%, ~5 Mt/yr)
Restrictions and conditions of use
- NO Hazardous Chemicals Operation Permit required (polymer light-hazard)
- **0% China VAT export rebate** for nylon-6
- Beijing 14th Five-Year Plan emphasises nylon-6 capacity additions for textile + engineering-plastic chains
Importer obligations
For Chinese-origin nylon-6 exported abroad, no IECSC obligation falls on the foreign importer. Light-regulatory profile. Major Chinese producers: same as caprolactam batch 14 (Sinopec Baling Hunan + Sinopec Shijiazhuang Hebei + Hengyi Petrochemical Zhejiang + Tianlong Shandong + Lujian Caprolactam Anhui + Yangmei Coal Industry-Hengtian Shanxi + Fujian Shenyuan Fujian + Hubei Sanning Hubei), integrated upstream caprolactam + downstream nylon-6 chain.
Required documents
- GACC export declaration with HS code 39081000
- Industrial-grade certificate per GB/T 17931
- Standard commercial invoice and packing list
- Producer-specific AD margin documentation for EU lane IF a current measure is in force (verify against EUR-Lex https://eur-lex.europa.eu/ before invoicing)
Common compliance traps
The pitfalls that have bitten importers on this lane in the past. None of these is theoretical.
- **0% China VAT export rebate** for nylon-6 (verify the current export-rebate schedule against the State Taxation Administration before invoicing)
- Major Chinese producers: same as caprolactam batch 14; integrated upstream + downstream chain dominates Chinese economics
- Capacity additions 2024-2026 at Sinopec Baling Phase 2 + Hengyi Phase 2 + Tianlong + Yangmei-Hengtian + Fujian Shenyuan extend Chinese capacity dominance (verify the most recent Phase 2 nameplate and commissioning year against the producer corporate sites or ICIS before quoting)
- EU trade-defence status on Chinese-origin nylon-6 unverified at audit (verify current measure status, regulation number, and per-producer rate against EUR-Lex https://eur-lex.europa.eu/ before invoicing); any active measure would flow back to Chinese producer pricing and shift volume to non-EU lanes (US Section 301 + ASEAN + Latin America + India)
- **Closes caprolactam batch 14 chain via ring-opening polymerisation**

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.
