2914.39.90.00 - Other

This classification, HTS Code 2914.39.90.00, serves as a residual category for aromatic ketones that do not possess other oxygen-containing functional groups and are not specifically enumerated in prior subheadings under the "Aromatic ketones without other oxygen function" heading. It encompasses a broad range of organic compounds where a ketone group (-C(=O)-) is directly attached to an aromatic ring system. The defining characteristic is the absence of additional oxygen functions, such as alcohols, ethers, aldehydes, or carboxylic acids, within the molecule.

This "Other" category distinguishes itself from its sibling, 2914.39.10.00, by excluding specific, named aromatic ketones. The sibling subheading precisely identifies 7-Acetyl-1,1,3,4,4,6-hexamethyl-tetra hydro naphthalene, 1-(2-Naphthalenyl) ethanone, and 6-Acetyl-1,1,2,3,3,5-hexamethylindan. Therefore, any aromatic ketone that does not fall under these explicit descriptions, and otherwise meets the criteria of aromatic ketones without other oxygen function, would be classified under 2914.39.90.00.

As this is a leaf node, there are no further subcategories for this HTS code. Classification within 2914.39.90.00 relies on the precise chemical structure of the compound and its compliance with the overarching definition of aromatic ketones without other oxygen function, while ensuring it is not specifically listed in any preceding or co-equal subheadings.
