Monoethanolamine (MEA) under TSCA

C2H7NO · 乙醇胺

Status: Active. Monoethanolamine is on the TSCA Active Inventory. **NOT typically Cal Prop 65 listed at MEA level** (verify against OEHHA https://oehha.ca.gov/proposition-65/proposition-65-list before relying; ethylene oxide feedstock is Cal Prop 65 listed as carcinogen + developmental / reproductive toxicant). NO active US AD/CVD case on Chinese-origin monoethanolamine currently (verify against access.trade.gov before invoicing). **DEA + DOJ: NOT on Chemical Diversion + Trafficking Act List I or List II precursor schedules** (verify against https://www.deadiversion.usdoj.gov/ before relying).

Monoethanolamine is TSCA-Active. OSHA PEL 3 ppm 8-hr TWA + 6 ppm STEL. **DEA NOT scheduled.** NO active US AD/CVD. DOT UN 2491 Class 8 PG III corrosive liquid. **Gas-treatment / amine-scrubbing ~40 to 50% + emerging carbon-capture absorbent + surfactant + detergent + cosmetics + cement-grinding aid downstream chains**. US is structurally a major producer + exporter (Dow + INEOS Plaquemine LA + Seadrift TX).
