2922.19.96.19 - Other

This classification, HTS 2922.19.96.19, pertains to "Other" N,N-(Dialkyl (methyl, ethyl, n-propyl or isopropyl)-2-aminoethanols and their protonated salts. It captures specific amino-alcohols that contain both amino and hydroxyl functional groups, with the alkyl substituents on the nitrogen atom being limited to methyl, ethyl, n-propyl, or isopropyl groups. These compounds are characterized by the presence of a secondary or tertiary amine attached to an ethanol backbone, where the specific alkyl groups define their inclusion in this category.

This category is distinguished from its sibling, 2922.19.96.10, which specifically enumerates N,N-Dimethyl-2-aminoethanol and N,N-diethyl-2-aminoethanol and their salts. HTS 2922.19.96.19 therefore covers N,N-(Dialkyl (methyl, ethyl, n-propyl or isopropyl)-2-aminoethanols where the alkyl substituents are n-propyl or isopropyl, or combinations thereof, not explicitly listed in the sibling. The "Other" designation at this level implies it captures remaining combinations of these specific dialkyl groups beyond the primary dimethyl and diethyl compounds.

As a leaf node, this classification does not have further subdivisions. Therefore, the focus remains on the precise chemical structure of the N,N-(Dialkyl (methyl, ethyl, n-propyl or isopropyl)-2-aminoethanols and their protonated salts that fall under this specific code. Classification relies on confirming the presence of the amino-alcohol structure with the specified n-propyl or isopropyl dialkyl substitutions on the nitrogen atom, and ensuring it does not meet the more specific criteria of the sibling category.
