2914.79 - Other:

This HTS category, 2914.79, encompasses aromatic ketones and quinones, as well as their derivatives, that have undergone halogenation, sulfonation, nitration, or nitrosation. These compounds are characterized by the presence of a ketone or quinone functional group on an aromatic ring, along with the addition of halogen atoms (chlorine, bromine, iodine, fluorine), sulfonic acid groups (-SO₃H), nitro groups (-NO₂), or nitroso groups (-NO) attached to the molecule.

Category 2914.79 stands apart from its sibling, 2914.71 (Chlordecone), by including all other halogenated, sulfonated, nitrated, or nitrosated derivatives of aromatic ketones and quinones that do not fall under specific named entries like chlordecone. This means that while 2914.71 is reserved for a very specific chemical compound, 2914.79 serves as a residual category for a broader range of related aromatic compounds with these modifications.

The subcategories within 2914.79 are further distinguished by their structural characteristics. The "Aromatic:" subdivision specifically addresses those derivatives where the ketone or quinone functional group is directly attached to an aromatic ring system. The "Other:" subdivision, conversely, is intended for derivatives that do not meet the strict criteria for the "Aromatic:" designation, potentially including compounds with modifications to side chains or more complex aromatic structures not explicitly covered elsewhere.
