2922.19.96.90 - Other

This HTS category, 2922.19.96.90, encompasses a broad residual classification for amino-alcohols that do not fall under more specific subheadings within the "Other" classification of amino-alcohols. These compounds are characterized by the presence of both an amino group (-NH2, -NHR, or -NR2) and a hydroxyl group (-OH) within the same molecule, and crucially, they do not contain any additional oxygen-containing functional groups such as aldehydes, ketones, carboxylic acids, or phenols. This residual category is a catch-all for amino-alcohols and their salts where specific structural features or other functional groups preclude their classification under more detailed subheadings.

This classification is distinguished from its sibling category, N,N-(Dialkyl (methyl, ethyl, n-propyl or isopropyl)-2-aminoethanols and their protonated salts. While both fall under the broader "Other" amino-alcohols, this sibling specifically targets a defined group of dialkyl-substituted aminoethanols. The present category, 2922.19.96.90, therefore, covers all other amino-alcohols that do not meet the precise structural and substituent criteria of that sibling, provided they adhere to the general definition of amino-alcohols without additional oxygen functions.

As this node represents a leaf node in the HTS structure, there are no further subcategories to introduce. Classification within this heading is determined by the exclusion of the compound from more specific amino-alcohol categories based on its molecular structure and the absence of other oxygen-containing functional groups beyond the single hydroxyl group. Examples of substances that might be classified here include amino-alcohols with longer alkyl chains or different arrangements of the amino and hydroxyl groups, as long as they do not fit into more narrowly defined tariff provisions.
