Acetone under K-REACH

C3H6O · 丙酮

Status: Registered. Acetone is registered under K-REACH and listed as a Priority Existing Chemical (PEC). Korean GHS classification matches REACH (Flam. Liq. 2, Eye Irrit. 2, STOT SE 3 narcotic effects). **Acetone IS on the Korean Drug Management Act precursor list (Class III)** under the Narcotics Control Act; Korean Customs Service + Korean National Police Agency Drug Management Division supervision applies. NOT on Korea TCCA Toxic Chemicals list. **Korea has substantial domestic cumene-process acetone capacity** (LG Chem Yeosu, Kumho P&B Yeosu, GS Caltex Yeosu, S-Oil Onsan) and is structurally balanced or modestly net-importer depending on year. KCFTA preferential zero-duty applies for Chinese-origin imports.

K-REACH treats acetone as a routine PEC-registered substance with no TCCA overlay. **The dominant practitioner-facing overhead is parallel Korean Drug Management Act Class III precursor compliance** (KCS + Korean National Police Agency Drug Management Division supervision, two-layer pattern with K-REACH). All five regimes (REACH + Cat 3, TSCA + DEA List II, IECSC + Easily-Made Drugs Cat 3, AICIS + Drug Control Act Cat III, K-REACH + Drug Management Act Class III) apply parallel drug-precursor + industrial-chemical regulation; this is the structural distinguishing pattern of acetone vs other substances in the dataset. Korea has substantial domestic cumene-process acetone capacity at Yeosu (LG Chem, Kumho P&B, GS Caltex) and Onsan (S-Oil) with comparable 1.6:1 phenol-acetone joint-product ratio to Chinese chain. KCFTA preferential zero-duty supports Chinese-origin supplemental supply. Korean BPA chain (Hyosung Chemicals, LG Chem) and MMA chain (Lotte Chemical, LG MMA) drive substantial captive demand. NO active Korean AD/CVD case.

Listing and threshold

Substance Acetone (CAS 67-64-1), C3H6O
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: Flam. Liq. 2 (H225), Eye Irrit. 2 (H319), STOT SE 3 (H336)
  • Signal word: DANGER. GHS pictograms: GHS02 + GHS07
  • Korea Occupational Safety and Health Act (KOSHA) workplace exposure standard: 500 ppm TWA
  • NOT on Korea TCCA Toxic Chemicals list
  • **Listed in Korean Drug Management Act precursor list (Class III)** under Narcotics Control Act
  • Korean Customs Service (KCS) HS code: 29141100
  • Listed in K-REACH database under "general industrial use, low-hazard, drug-precursor-scheduled"
  • NOT classified as carcinogen, mutagen, or reproductive toxicant under Korean GHS

Restrictions and conditions of use

  • No TCCA Toxic Chemicals Handling Permit required
  • No Chemical Accident Prevention Plan (CAPP) required
  • **Korean Drug Management Act Class III precursor obligations**: operator registration with KCS + Korean National Police Agency Drug Management Division, transaction record-keeping, suspicious-transaction reporting
  • 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 acetone currently
  • KCFTA preferential zero-duty applies to Chinese-origin acetone (HS 29141100); 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). **The dominant practitioner-facing overhead is parallel Korean Drug Management Act Class III precursor compliance** (KCS + Korean National Police Agency Drug Management Division supervision, operator registration, transaction record-keeping, suspicious-transaction reporting). Korean cumene-process producers (LG Chem Yeosu, Kumho P&B Yeosu, GS Caltex Yeosu, S-Oil Onsan) cover a substantial portion of domestic demand; supplemental imports flow during plant outages and grade-specific applications. Korean downstream consumers include KCC Corporation (paints), Hyosung Chemicals (BPA chain), LG Chem (BPA chain), Lotte Chemical (MMA chain).

Required documents

  • K-REACH registration number on Korean side (registrant or OR-appointed)
  • Korean-language MSDS compliant with Korean GHS reflecting H225 / H319 / H336 classification
  • Korean Customs Service (KCS) declaration with HS code 29141100
  • **Korean Drug Management Act Class III precursor declaration**
  • China-Korea FTA Form CO certificate of origin for preferential treatment
  • Industrial-grade specification certificate (minimum 99.5% 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
  • **Korean Drug Management Act Class III precursor compliance is parallel to K-REACH** (similar two-layer pattern as EU Cat 3 + REACH, China Easily-Made Drugs Cat 3 + IECSC, Australian Drug Control Act + AICIS, US DEA List II + TSCA). All five regimes apply parallel drug-precursor + industrial-chemical regulation
  • Korea has substantial domestic cumene-process acetone capacity at Yeosu (LG Chem, Kumho P&B, GS Caltex) and Onsan (S-Oil); imports are supplemental for plant outages and grade-specific applications
  • KCFTA preferential zero-duty applies but verify producer-specific eligibility (Form CO certified by Chinese authority)
  • No active Korean AD/CVD case on Chinese acetone currently
  • Korean cumene-process phenol-acetone integrated chain at Yeosu (LG Chem, Kumho P&B, GS Caltex) is comparable to Chinese coastal chain (Sinopec Yanshan, Mitsui-Sinopec, Wanhua); 1.6:1 phenol-acetone joint-product ratio is identical structural feature
  • Korean BPA chain (Hyosung Chemicals, LG Chem, Mitsubishi Chemical Korea) and MMA chain (Lotte Chemical Yeosu, LG MMA Yeosu) drive substantial captive acetone demand
