2917.39.30.00 - Products described in additional U.S. note 3 to section VI

This classification, HTS 2917.39.30.00, pertains to aromatic polycarboxylic acids, their anhydrides, halides, peroxides, and peroxyacids, and their derivatives, that are specifically designated by Additional U.S. Note 3 to Section VI. These substances are characterized by their aromatic ring structures bearing multiple carboxyl groups or their related functional derivatives. This subheading captures those products that do not fall under more specific subheadings within the aromatic polycarboxylic acid category, and are not otherwise enumerated.

The distinguishing feature of this subheading lies in its reliance on Additional U.S. Note 3 for definitive product inclusion. Unlike other "Other" subheadings that may rely on general chemical structure or function, HTS 2917.39.30.00 is narrowly defined by this specific U.S. note, which may provide a list of qualifying substances or criteria for their inclusion. This ensures a precise classification for particular aromatic polycarboxylic acid derivatives that might otherwise present ambiguity.

As a leaf node, HTS 2917.39.30.00 does not have further subdivisions. Therefore, classification into this subheading is final. Importers and exporters should carefully review Additional U.S. Note 3 to Section VI to determine if their specific aromatic polycarboxylic acid, anhydride, halide, peroxide, peroxyacid, or derivative product meets the criteria for inclusion under this classification. This note is paramount for accurate declaration and avoids potential misclassification.
