Amino-Alcohols with One Oxygen Function (NESOI), Their Ethers, Esters, and Salts

N,N-dialkyl-2-aminoethanols, including N,N-dimethyl- and N,N-diethyl-2-aminoethanol, are CWC Schedule 2 precursors because they can be used in the synthesis of nerve agents. Imports require Commerce Department BIS permits under the Chemical Weapons Convention Regulations, and shipments are subject to quantity declaration requirements. Importers should ensure all CWC documentation is filed before the goods arrive at the US border.

Line 2922190900 applies to aromatic amino-alcohols that are classified as drugs — meaning the compound itself is a recognized pharmaceutical active ingredient or is imported specifically for drug manufacture. If the compound has a dual industrial and pharmaceutical use, the principal use at the time of importation governs, and the importer should retain documentation such as a drug master file reference, pharmacopoeial monograph, or end-use certificate to support the drug classification.
