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**
