2914.22 - Cyclohexanone and methylcyclohexanones:

This HTS classification covers cyclohexanone and methylcyclohexanones. Cyclohexanone is a cyclic ketone widely used as an industrial solvent, particularly in the production of nylon and as a precursor for caprolactam. Methylcyclohexanones are isomers of cyclohexanone that incorporate a methyl group on the cyclohexane ring, also finding applications as solvents and intermediates in various chemical syntheses. These compounds are characterized by their cyclic structure and the presence of a ketone functional group.

Within the broader category of "Cyclanic, cyclenic or cycloterpenic ketones without other oxygen function," this specific heading distinguishes itself from its sibling, 2914.23.00.00, which exclusively covers ionones and methylionones. Ionones and methylionones, while also cyclic ketones, possess a distinct conjugated double bond system and are primarily known for their use in perfumery and as flavorings, differing significantly in structure and application from cyclohexanone and methylcyclohexanones.

This category is further subdivided to provide more granular classification. The primary subcategories are 2914.22.10.00 for cyclohexanone and 2914.22.20.00 for methylcyclohexanones. This distinction is important for customs purposes, as these are distinct chemical entities with potentially different trade volumes, regulatory considerations, and applications. The subcategories allow for precise identification of the specific compound being imported or exported.
