2-Ethylhexanol (2-EH) under K-REACH

C8H18O · 2-乙基己醇

Status: Registered. 2-Ethylhexanol is registered under K-REACH. NOT on Korea TCCA Toxic Chemicals list (verify against the current TCCA Toxic Chemicals list at https://www.nics.go.kr/ before relying). NOT on Korean Drug Management Act precursor list. NO active Korean AD/CVD case on Chinese-origin 2-EH (verify against https://www.kita.org/ or Korea Trade Commission filings before invoicing). Korea has substantial domestic 2-EH production at Yeosu plus Daesan (LG Chem, Lotte Chemical, Hanwha Solutions oxo-alcohol capacity); structurally balanced. KCFTA preferential zero-duty applies for Chinese-origin imports.

K-REACH treats 2-EH as a routine registered substance with no TCCA overlay. Korea has substantial domestic 2-EH production at Yeosu plus Daesan oxo-alcohol capacity. NO active Korean AD/CVD case. **2-EH distinguishing pattern across all 5 regimes**: oxo-process from propylene plus syngas plus aldol condensation of n-butyraldehyde (~95 percent of global capacity) production route + DEHP plasticiser feedstock chain (the dominant downstream; ~50 to 55 percent of demand globally) plus 2-EH acrylate ester chain (~15 to 20 percent) plus 2-EH nitrate cetane improver (~5 to 10 percent) plus solvent and surfactant intermediates + sister to n-butanol oxo-alcohol chain + downstream DEHP IS on Annex XIV (REACH) and IS under TSCA Section 6 Risk Evaluation.
