2922.39.45.00 - Other

This HTS classification, 2922.39.45.00, pertains to a specific subset of amino-aldehydes, amino-ketones, and amino-quinones that fall under the broader category of "Other" aromatic compounds within the oxygen-function amino-compounds chapter. These are organic chemicals characterized by the presence of both an amino group (-NH2 or substituted amino) and either an aldehyde (-CHO), ketone (>C=O), or quinone functional group, attached to an aromatic ring system. The "Other" designation signifies that these compounds do not fit into more specifically defined subcategories within the aromatic classification of amino-aldehydes, amino-ketones, and amino-quinones.

This particular category distinguishes itself from its sibling, 2922.39.25.00, by excluding products that are specifically described in additional U.S. note 3 to section VI. This note often delineates certain substances or preparations that, despite meeting the chemical criteria, are placed in a different classification for trade or regulatory purposes. Therefore, 2922.39.45.00 captures aromatic amino-aldehydes, amino-ketones, and amino-quinones that are *not* subject to the provisions of that specific additional U.S. note.

As this is a leaf node in the HTS classification, there are no further subcategories. Classification within 2922.39.45.00 is determined by the chemical structure meeting the criteria of an aromatic amino-aldehyde, amino-ketone, or amino-quinone and not being covered by any more specific heading or subheading, including the aforementioned additional U.S. note 3. Importers and exporters should carefully examine the chemical composition and verify that the product does not fall under any more precise description within the HTS.
