2914.22.20.00 - Methylcyclohexanones

This HTS category, 2914.22.20.00, specifically covers methylcyclohexanones. These are cyclic ketones derived from the cyclohexane structure, where one or more hydrogen atoms on the ring have been replaced by methyl groups. Methylcyclohexanones are organic compounds characterized by the presence of a carbonyl group (C=O) within a six-membered saturated carbon ring, further substituted with one or more methyl (CH3) groups. They are typically colorless liquids or low-melting solids and find various applications as solvents and intermediates in the synthesis of other chemicals.

Distinguishing this category from its sibling, 2914.22.10.00 (Cyclohexanone), is crucial. Cyclohexanone is the unsubstituted cyclic ketone, meaning it lacks any methyl group substitutions on the ring. Therefore, the presence of at least one methyl group attached to the cyclohexane ring is the defining characteristic for classification under 2914.22.20.00, whereas cyclohexanone is classified separately.

As this is a leaf node in the HTS structure, there are no further subcategories. Classification at this level is definitive for methylcyclohexanones based on their chemical structure. When encountering these substances, confirm the presence of both the cyclohexanone ring structure and at least one methyl group substituent to ensure accurate classification under this specific heading.
