Last updated: August 2026 dataDiethanolamine is a secondary alkanolamine widely used as a surfactant intermediate, corrosion inhibitor in metalworking fluids, and gas-treating solvent, and it is a key building block for cocamide DEA in personal care formulations. Belgium and Saudi Arabia lead US supply, with Germany and Taiwan also contributing, a pattern that reflects both European specialty-chemical capacity and Gulf petrochemical integration. The single tariff line 2922120001 covers the compound and all its salt forms, so the commercial invoice should specify whether the shipment is free base or a particular salt to support accurate classification.

Diethanolamine is subject to TSCA inventory requirements, and importers must file a TSCA certification at entry. DEA is also listed under California Proposition 65 as a chemical known to cause cancer, which affects downstream labeling obligations for products sold in California, though this does not alter the federal import classification.
Diethanolamine (a secondary amine with two hydroxyethyl groups) is classified at 2922120001, while triethanolamine (a tertiary amine with three hydroxyethyl groups) falls under heading 292215. The distinction is based on the degree of ethoxylation of the nitrogen atom, and the chemical specification or CAS number on the commercial invoice is the primary classification evidence.
