2924.21.20.00 - Products described in additional U.S. note 3 to section VI 🖩

This HTS classification, 2924.21.20.00, encompasses specific carboxyamide-function compounds and amide-function compounds of carbonic acid that are described under additional U.S. note 3 to section VI. These are cyclic amides (including cyclic carbamates) and their derivatives, specifically falling within the ureine and their derivatives category. The defining characteristic of this sub-subheading is that these aromatic cyclic amides are not otherwise specified or covered by preceding subheadings within the 2924.21.20 structure, thus representing a residual category for particular ureine derivatives.

This classification differs from its sibling, 2924.21.45.00, which also pertains to "Other" aromatic cyclic amides. While both are residual categories, the precise distinction lies within the specific enumeration or exclusion criteria detailed in U.S. note 3 to section VI, which acts as the definitive rule for inclusion within 2924.21.20.00. Without further specification within the HTS text itself beyond the reference to this additional U.S. note, importers must meticulously consult that specific note to determine correct placement.

As this is a leaf node, there are no further subcategories branching from 2924.21.20.00. Therefore, the classification is final at this level, and any product meeting the criteria of cyclic amides (including cyclic carbamates) and their derivatives, specifically ureines and their derivatives, which are aromatic and are explicitly identified as belonging to this category by additional U.S. note 3 to section VI, will be classified here. This necessitates a thorough understanding of the scope and exclusions outlined in that particular note to avoid misclassification.
