Triethanolamine (TEA) under K-REACH

C6H15NO3 · 三乙醇胺

Status: Registered. Triethanolamine is registered under K-REACH. NOT on Korea TCCA Toxic Chemicals list at TEA level (verify against the current TCCA Toxic Chemicals list at https://www.nics.go.kr/ before relying). **IARC Group 3 (not classifiable) Volume 101 (verify year against https://monographs.iarc.who.int/), DISTINCT from DEA Group 2B in same Volume** (verify against https://monographs.iarc.who.int/). NO active Korean AD/CVD case on Chinese-origin triethanolamine. KCFTA preferential zero-duty applies for Chinese-origin imports. Korea has both domestic production (Lotte Chemical Yeosu + LG Chem Yeosu) and Chinese-origin import dependency for cement-grinding aid + cosmetics + corrosion inhibitor sectors.

K-REACH treats triethanolamine as a registered substance with no TCCA overlay. KCFTA preferential zero-duty. NO active Korean AD/CVD. Korea has both domestic production (Lotte Chemical Yeosu + LG Chem Yeosu) and Chinese-origin import dependency. **TEA distinguishing pattern across all 5 regimes**: Production as TEA fraction of alkanolamine product slate from ammonia + ethylene oxide reaction (1:3+ NH3 : EO molar ratio maximises TEA fraction); **TEA is the lightest hazard alkanolamine: Eye Irrit. 2 + Skin Irrit. 2 only + IARC Group 3 (not classifiable) Volume 101 (verify year against https://monographs.iarc.who.int/) DISTINCT from DEA Group 2B in same Volume + NOT typically Cal Prop 65 listed + NOT typically SUSMP scheduled at TEA level + NOT EU Cosmetic Annex II prohibited (FDA + TGA + EU Reg 1223/2009 + MFDS + ChP all permit TEA in cosmetics with nitrosamine-precursor controls)**; **cement-grinding aid ~30 to 40% of global TEA consumption (in cement clinker grinding to improve mill throughput + early strength) + cosmetics (TEA-stearate + TEA-laureth sulphate emulsifier + pH-adjuster in lotions + creams + shampoos) + corrosion inhibitor (cutting fluids + boiler-water treatment + metal-cleaning) + photographic developer + surfactant + ag intermediate + textile-processing auxiliary downstream chains**; NOT regulated as dangerous goods at solid / liquid form; NIOSH REL + ACGIH TLV-TWA + Korean MoEL OEL + Safe Work Australia WES all 5 mg/m3 inhalable; **NOT on EU Drug Precursors Reg 273/2004 + Reg 2015/1011 + NOT on US DEA schedules + NOT on China State Council 易制毒化学品管理条例 + NOT on Australian Drug Precursor list + NOT on Korean Act on Control of Narcotics at TEA level**; major non-Chinese producers Dow Chemical (USA Plaquemine LA + Seadrift TX) + INEOS (USA Plaquemine LA) + Mitsubishi Chemical (Japan Yokkaichi) + Lotte Chemical (Korea Yeosu) + LG Chem (Korea Yeosu); **China major TEA producer + exporter** (SINOPEC Maoming Petrochemical Guangdong + SINOPEC Jinling Petrochemical Nanjing + Jinghong Energy Inner Mongolia + Jiangsu Yida Chemical Yangzhou).
