2922.18.00.00 - 2-(N,N-Diisopropylamino)ethanol

This classification covers amino-alcohols, which are organic compounds containing both an amino (-NH2, -NHR, or -NR2) group and a hydroxyl (-OH) group. Specifically, this category is for amino-alcohols where the hydroxyl group is the sole oxygen-containing functional group, excluding those with multiple oxygen functions. Salts derived from these amino-alcohols are also included within this group.

Within the broader category of amino-alcohols, this specific sub-heading, 2922.18.00.00, distinguishes itself by covering amino-alcohols that are not explicitly listed under other more specific subheadings. For instance, it is distinct from the monoethanolamine (2922.11.00.00), diethanolamine (2922.12.00.01), and triethanolamine (2922.15.00.00) which are classified separately due to their prevalence and specific industrial applications. It also differentiates from compounds like dextropropoxyphene (2922.14.00.00) and diethylammonium perfluorooctane sulfonate (2922.16.00.00), which possess unique structural or application-specific classifications.

As a leaf node within the HTS structure, 2922.18.00.00 does not have further subcategories. Therefore, classification into this HTS code relies on identifying an amino-alcohol that fits the general definition of an amino-alcohol with a single oxygen function and is not specifically enumerated elsewhere. The chemical structure, particularly the presence of both an amino and a hydroxyl group, and the absence of other oxygen-containing functional groups, are key determinative factors for classification under this heading.
