2921.49.45.00 - Products described in additional U.S. note 3 to section VI

This classification, HTS Code 2921.49.45.00, specifically identifies aromatic monoamines and their derivatives that fall under the broader "Other" subcategories within their respective hierarchical levels. It represents a residual category for these aromatic amine compounds that do not fit into more specific enumerations within Chapter 29, provided they are described in Additional U.S. Note 3 to Section VI. This note often pertains to specific substances or groups of substances that require special consideration for import or export purposes.

Unlike its sibling category, 2921.49.50.00, which is also designated as "Other," this particular code is distinguished by its direct reference to Additional U.S. Note 3. This implies that the classification hinges not only on the chemical structure of the aromatic monoamine derivative but also on whether it is explicitly mentioned or governed by the provisions within that specific U.S. note. Therefore, proper classification requires a thorough review of both the chemical identity and the stipulations of Additional U.S. Note 3.

As this is a leaf node in the HTS, there are no further subcategories. Classification under this code signifies that the product is an aromatic monoamine or derivative thereof, not specifically itemized elsewhere at lower levels, and importantly, it meets the criteria outlined in Additional U.S. Note 3 to Section VI. Examples might include specialized aromatic amines or their derivatives used in specific industrial applications or research that are not otherwise broadly covered.
