Aniline (aminobenzene) under K-REACH

C6H7N · 苯胺

Status: Registered. Aniline is registered under K-REACH and listed as a Priority Existing Chemical (PEC). Korean GHS classification matches REACH (Carc 2 + Muta 2 + Acute Tox. 3 + STOT RE 1 + Skin Sens 1 + Aquatic Chronic 1). **Aniline IS on Korea TCCA Toxic Chemicals list**: TCCA Toxic Chemicals Handling Permit at destination facility required (parallel layer to K-REACH chemical registration; mirror of phenol batch 13 + sulfuric acid batch 2 + formaldehyde batch 18 + benzene batch 22 patterns). NOT on Korean Drug Management Act precursor list. NO active Korean AD/CVD case on Chinese-origin aniline. Korea has substantial domestic aniline production (Hyosung Chemicals Yongjeong + Hyosung Chemicals Yeosu integrated MDI chain, Kumho Mitsui integrated TDI chain at Yeosu); structurally balanced. KCFTA preferential zero-duty applies for Chinese-origin imports.

K-REACH treats aniline as a routine PEC-registered substance but **TCCA Toxic Chemicals Handling Permit at destination facility is the dominant practitioner overhead** (parallel layer with K-REACH; mirror of phenol batch 13 + sulfuric acid batch 2 + formaldehyde batch 18 + benzene batch 22 patterns). Korea has **substantial domestic aniline production at Yeosu** (Hyosung Chemicals Yongjeong + Hyosung Chemicals Yeosu integrated MDI chain, Kumho Mitsui integrated TDI chain at Yeosu); structurally balanced. NO active Korean AD/CVD case. KCFTA preferential zero-duty supports Chinese-origin supplemental supply. Korean MDI / TDI chain at Yeosu is among world's largest alongside Chinese Wanhua + Sinopec capacity. **Aniline distinguishing pattern across all 5 regimes**: MDI / TDI chain primary feedstock (~85% of demand) + nitrobenzene hydrogenation route + benzene (batch 22) ultimate downstream + Wanhua Chemical Yantai world's largest MDI producer integrated upstream + China Highly Toxic Chemicals dual-permit + Korea TCCA + Australia SUSMP Schedule 7; Chinese export volume structurally LIMITED because Wanhua + Sinopec consume most domestic capacity for integrated MDI / TDI chain.

Listing and threshold

Substance Aniline (aminobenzene) (CAS 62-53-3), C6H7N
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: Carc. 2 (H351), Muta. 2 (H341), Acute Tox. 3 oral / dermal / inhalation (H301 / H311 / H331), STOT RE 1 (H372), Skin Sens. 1 (H317), Eye Dam. 1 (H318), Aquatic Acute 1 (H400), Aquatic Chronic 1 (H410)
  • Signal word: DANGER. GHS pictograms: GHS06 + GHS08 + GHS09
  • Korea Occupational Safety and Health Act (KOSHA) workplace exposure standard: 2 ppm (skin notation) 8-hr TWA
  • **Listed in Korea TCCA Toxic Chemicals list**
  • NOT on Korean Drug Management Act precursor list
  • Korean Customs Service (KCS) HS code: 292141
  • Listed in K-REACH database under "general industrial use, hazardous, toxic chemical, carcinogen Cat 2, mutagen Cat 2, target organ"
  • **IARC: Group 2B (possibly carcinogenic to humans)**

Restrictions and conditions of use

  • **TCCA Toxic Chemicals Handling Permit at destination facility required** (parallel layer to K-REACH chemical registration; mirror of phenol batch 13 + sulfuric acid batch 2 + formaldehyde batch 18 + benzene batch 22 patterns)
  • Chemical Accident Prevention Plan (CAPP) may be required at handling facilities above declared thresholds
  • Korea Industrial Safety and Health Act (KOSHA) MSDS in Korean required at workplace
  • Korea Customs Service requires K-REACH registration number on import declaration
  • NO active Korean AD/CVD case on Chinese-origin aniline currently
  • KCFTA preferential zero-duty applies to Chinese-origin aniline (HS 292141); verify producer-specific eligibility (Form CO certified by Chinese authority)

Importer obligations

The Korean importer of record must hold K-REACH registration in their own name or rely on an Only Representative (OR). **TCCA Toxic Chemicals Handling Permit at destination facility is the dominant practitioner-facing overhead** (parallel layer to K-REACH chemical registration; mirror of phenol batch 13 + sulfuric acid batch 2 + formaldehyde batch 18 + benzene batch 22 patterns). Korea has substantial domestic aniline production (Hyosung Chemicals Yongjeong + Hyosung Chemicals Yeosu integrated MDI chain, Kumho Mitsui integrated TDI chain at Yeosu); supplemental imports flow during plant outages. Korean MDI / TDI chain at Yeosu is among world's largest alongside Chinese Wanhua + Sinopec capacity.

Required documents

  • K-REACH registration number on Korean side (registrant or OR-appointed)
  • Korean-language MSDS compliant with Korean GHS reflecting H301 / H311 / H317 / H318 / H331 / H341 / H351 / H372 / H410 classification
  • Korean Customs Service (KCS) declaration with HS code 292141
  • **TCCA Toxic Chemicals Handling Permit** at destination facility
  • China-Korea FTA Form CO certificate of origin for preferential treatment
  • Industrial-grade specification certificate (minimum 99.9% purity)

Common compliance traps

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

  • Korean GHS hazard-statement codes use H-codes mapped to Korean translations; SDS in English-only is rejected at workplace inspection
  • **TCCA Toxic Chemicals Handling Permit at destination facility is the dominant practitioner overhead** (parallel layer with K-REACH; mirror of phenol batch 13 + sulfuric acid batch 2 + formaldehyde batch 18 + benzene batch 22 patterns)
  • Korea has substantial domestic aniline production at Yeosu (Hyosung Chemicals Yongjeong + Hyosung Chemicals Yeosu integrated MDI chain, Kumho Mitsui integrated TDI chain)
  • KCFTA preferential zero-duty applies; verify producer-specific eligibility
  • No active Korean AD/CVD case on Chinese aniline currently
  • Korean MDI / TDI chain at Yeosu is among world's largest alongside Chinese Wanhua + Sinopec capacity
  • Korean downstream consumers: Hyosung Chemicals (MDI chain via Yongjeong + Yeosu integrated upstream aniline), Kumho Mitsui (TDI chain at Yeosu via integrated upstream aniline)
  • Female-of-child-bearing-age workplace protection planning for Carc 2 + Muta 2 substances under Korean Industrial Safety and Health Act
