Acrylic acid (prop-2-enoic acid) under K-REACH

C3H4O2 · 丙烯酸

Status: Registered. Acrylic acid is registered under K-REACH and listed as a Priority Existing Chemical (PEC). NOT on Korea TCCA Toxic Chemicals list. NOT on Korean Drug Management Act precursor list. NO active Korean AD/CVD case. Korea has substantial domestic acrylic acid production (LG Chem Yeosu, Toagosei Korea Daesan); structurally balanced. KCFTA preferential zero-duty applies for Chinese-origin imports.

K-REACH treats acrylic acid as a routine PEC-registered substance with no TCCA overlay. Korea has substantial domestic acrylic acid production at Yeosu + Daesan integrated with acrylic ester chains. NO active Korean AD/CVD case. **Acrylic acid distinguishing pattern across all 5 regimes**: closes propylene oxidation chain (propylene + air → acrolein → acrylic acid; ~99% globally) + Skin Corr. 1A + Acute Tox. 4 + Aquatic Acute 1 + SAP / superabsorbent polymer (sodium polyacrylate) primary downstream chain (~30% of demand, hygiene products + diapers + agricultural water-retention) + acrylic ester chain (methyl + ethyl + butyl + 2-EH acrylate, ~50% combined for paint + coating + adhesive + textile-finishing).

Listing and threshold

Substance Acrylic acid (prop-2-enoic acid) (CAS 79-10-7), C3H4O2
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
  • NOT on Korea TCCA Toxic Chemicals list
  • Korean Customs Service (KCS) HS code: 291611

Restrictions and conditions of use

  • No TCCA Toxic Chemicals Handling Permit required
  • Korea Industrial Safety and Health Act (KOSHA) MSDS in Korean required
  • NO active Korean AD/CVD case
  • KCFTA preferential zero-duty applies

Importer obligations

The Korean importer of record must hold K-REACH registration. Korea has substantial domestic acrylic acid production at Yeosu + Daesan. Korean downstream consumers: LG Chem (acrylic ester chain at Yeosu), Toagosei Korea (acrylic ester chain at Daesan), Korean diaper / hygiene product industry (SAP demand), Korean paint + coating industry.

Required documents

  • K-REACH registration number on Korean side
  • Korean-language MSDS
  • Korean Customs Service (KCS) declaration with HS code 291611
  • China-Korea FTA Form CO

Common compliance traps
