Isophorone (3,5,5-Trimethylcyclohex-2-en-1-one)
Isophorone is a clear, colorless to pale yellow liquid ketone with the chemical formula C9H14O, specifically classified as a cyclenic ketone without other oxygen functions. It falls under HTS 2914.29.10.00 due to its precise chemical structure matching the legal definition of isophorone in Chapter 29 for separate chemically defined organic compounds. Primarily used as an industrial solvent and chemical intermediate.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing other oxygen functions beyond ketone group
Mixtures or derivatives with additional oxygen functions like hydroxyl groups classify under the 'other' cyclanic/cyclenic ketones provision later in numerical order per Chapter 29 notes.
If imported as a formulated mixture with solvents or additives
Chemical preparations not chemically defined as pure compounds fall under Chapter 38 for prepared chemical mixtures, excluding Chapter 29's scope for separate organic compounds.
If technically classified as a cyclic alcohol precursor rather than ketone
Alternative structure interpretation as unsaturated cyclic alcohol would shift to Chapter 29 acyclic/cyclanic alcohols, though isophorone's ketone function prevails.
