2912.29.60 - Other

This HTS category, "Other," within the classification of cyclic aldehydes without other oxygen function, serves as a residual grouping for compounds that do not fit into more specifically defined subcategories at this level. It encompasses a diverse range of cyclic aldehydes whose defining characteristic is the presence of an aldehyde group (-CHO) attached to a ring structure, without any other oxygen-containing functional groups (such as hydroxyl, ether, or ketone).

Unlike its sibling categories, which explicitly name or group specific substances like phenylacetaldehyde, 3,4-dimethylbenzaldehyde, paraldehyde USP grade, and p-tolualdehyde, this "Other" classification captures cyclic aldehydes not otherwise enumerated. Therefore, the primary differentiator from siblings is the absence of a specific named or defined product falling within those other categories.

This residual category is further subdivided to allow for more precise classification based on the intended use or specific nature of the cyclic aldehyde. The subcategory "2912.29.60.10: Odoriferous or flavoring compounds" designates cyclic aldehydes primarily utilized for their aromatic or taste-enhancing properties, commonly found in the fragrance and food industries. The remaining products within this "Other" grouping are then directed to the "2912.29.60.90: Other" subcategory, ensuring comprehensive coverage for all cyclic aldehydes not specifically identified elsewhere.
