2915.60.50.00 - Other

This HTS category, 2915.60.50.00, encompasses "Other" derivatives of butanoic acids and pentanoic acids, which are saturated acyclic monocarboxylic acids. Following the broader classification for carboxylic acids, this specific subheading captures those compounds that do not fit into more narrowly defined categories within the butanoic and pentanoic acid derivatives. This includes a wide array of chemical compounds derived from butanoic acid (butyric acid) and pentanoic acid (valeric acid), such as their halogenated, sulfonated, nitrated, or nitrosated forms, provided they are not specifically classified elsewhere.

Crucially, this category serves as a residual classification for butanoic and pentanoic acid derivatives. It is distinguished from its sibling category, 2915.60.10.00 ("Aromatic"), which is reserved for butanoic and pentanoic acid derivatives that contain an aromatic ring structure. Therefore, the key differentiator for classification under 2915.60.50.00 is the absence of aromaticity in the molecular structure of the derivative. This "Other" designation ensures that all relevant derivatives of these specific carboxylic acids are accounted for within the tariff schedule.

As this is a leaf node, there are no further subcategories. Classification under 2915.60.50.00 hinges on confirming that the compound is a derivative of butanoic or pentanoic acid and does not possess aromatic characteristics, nor does it fall under any other more specific description within Chapter 29 related to saturated acyclic monocarboxylic acids and their derivatives. Practical classification would involve consulting chemical nomenclature and structure to ensure it meets the criteria of being derived from butanoic or pentanoic acid and is not otherwise specified.
