Acrylonitrile under K-REACH

C3H3N · 丙烯腈

Status: Registered. Acrylonitrile is registered under K-REACH and listed as a Priority Existing Chemical (PEC). **Acrylonitrile IS on Korea TCCA Toxic Chemicals list**. NOT on Korean Drug Management Act precursor list. NO active Korean AD/CVD case on Chinese-origin acrylonitrile. Korea has substantial domestic acrylonitrile production (LG Chem Yeosu + Tongsuh Petrochemical Ulsan, integrated with Hyosung carbon-fibre chain). KCFTA preferential zero-duty applies for Chinese-origin imports.

K-REACH treats acrylonitrile as a routine PEC-registered substance but **TCCA Toxic Chemicals Handling Permit at destination facility is the dominant practitioner overhead**. Korea has substantial domestic acrylonitrile production at Yeosu + Ulsan. Korean carbon-fibre chain (Hyosung Advanced Materials + Toray Tongsuh) is grade-defining premium application. **Acrylonitrile distinguishing pattern across all 5 regimes**: closes butadiene batch 27 + ammonia batch 37 + propylene chains via SOHIO ammoxidation + Carc 1B + Muta 2 + Acute Tox. 3 + Skin Sens 1 + IARC classification under re-evaluation in Monograph Volume 136 (2025); verify current Group at https://monographs.iarc.who.int/monographs-available/ + REACH SVHC candidate-list inclusion since 13 January 2010 (NOT on Annex XIV authorisation list, common confusion) + verify current EU AD measures against the EU Official Journal before invoicing + ABS / SAN / acrylic fibre / adiponitrile / NBR / carbon-fibre PAN primary downstream chains + completes ABS triangle with styrene batch 25 + butadiene batch 27.

Listing and threshold

Substance Acrylonitrile (CAS 107-13-1), C3H3N
Regime Korea Act on the Registration and Evaluation of Chemicals (Act No. 11789, "K-REACH" amended 2018)
Jurisdiction Republic of Korea
Status Registered
Tonnage threshold K-REACH registration required for existing chemicals manufactured or imported >1 tonne/year (verified per Korean Ministry of Environment / NIER guidance, https://chemical.chemlinked.com/chempedia/k-reach; threshold for new substances was reduced from 0.1 t/y to 1 t/y effective 1 January 2025 per K-REACH 2025 amendment)

Classifications under this regime

  • Korean GHS classification: full hazard profile matching REACH
  • Signal word: DANGER. GHS pictograms: GHS02 + GHS06 + GHS08 + GHS09
  • Korea Occupational Safety and Health Act (KOSHA) workplace exposure standard: 2 ppm 8-hr TWA
  • **Listed in Korea TCCA Toxic Chemicals list**
  • NOT on Korean Drug Management Act precursor list
  • Korean Customs Service (KCS) HS code: 292610
  • **IARC: acrylonitrile re-evaluated in Monograph Volume 136 (2025); prior Volume 71 (1999) assessed acrylonitrile at Group 2B. Verify current Group classification against https://monographs.iarc.who.int/list-of-classifications/ before relying**

Restrictions and conditions of use

  • **TCCA Toxic Chemicals Handling Permit at destination facility required**
  • Chemical Accident Prevention Plan (CAPP) may be required
  • Korea Industrial Safety and Health Act (KOSHA) MSDS in Korean required
  • NO active Korean AD/CVD case on Chinese-origin acrylonitrile currently
  • KCFTA preferential zero-duty applies

Importer obligations

The Korean importer of record must hold K-REACH registration. **TCCA Toxic Chemicals Handling Permit at destination facility is the dominant practitioner-facing overhead**. Korea has substantial domestic production (LG Chem Yeosu + Tongsuh Petrochemical Ulsan integrated with Hyosung carbon-fibre chain). Korean downstream consumers: LG Chem (ABS chain), Tongsuh Petrochemical (acrylic fibre + carbon-fibre precursor PAN chain), Kumho Petrochemical (NBR chain via butadiene batch 27 + acrylonitrile), Hyosung Advanced Materials (carbon-fibre tow chain).

Required documents

  • K-REACH registration number on Korean side
  • Korean-language MSDS
  • Korean Customs Service (KCS) declaration with HS code 292610
  • **TCCA Toxic Chemicals Handling Permit** at destination facility
  • China-Korea FTA Form CO

Common compliance traps

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

  • **TCCA Toxic Chemicals Handling Permit at destination facility is the dominant practitioner overhead**
  • Korea has substantial domestic acrylonitrile production (LG Chem Yeosu + Tongsuh Petrochemical Ulsan)
  • Korean carbon-fibre chain (Hyosung Advanced Materials Toray Tongsuh) is grade-defining premium application
  • NO active Korean AD/CVD case
