2906.19.10.00 - 4,4'-Isopropylidenedicyclohexanol; and mixtures containing not less than 90 percent by weight of stereoisomers of 2-isopropyl- 5-methylcyclohexanol, but containing not more than 30 percent by weight of any one such stereoisomer

This classification, 2906.19.10.00, pertains to specific cyclanic alcohols. It encompasses 4,4'-Isopropylidenedicyclohexanol and mixtures of stereoisomers of 2-isopropyl-5-methylcyclohexanol. A key characteristic of these mixtures is their composition: they must contain at least 90 percent by weight of stereoisomers of 2-isopropyl-5-methylcyclohexanol, while simultaneously having no single stereoisomer present in an amount exceeding 30 percent by weight. This precise compositional requirement is crucial for correct classification within this heading.

Distinguishing this category from its siblings, 2906.19.30.00 covers terpineols, which are distinct cyclic terpenoid alcohols. The "Other" category, 2906.19.50.00, serves as a residual classification for cyclanic alcohols not specifically listed elsewhere. Therefore, 2906.19.10.00 is reserved for the precisely defined compounds and mixtures as described, excluding other types of cyclanic alcohols like terpineols.

As this is a leaf node within the HTS, there are no further subcategories. Classification decisions at this level rely heavily on the chemical identity and, in the case of mixtures, the precise weight percentages of the specified stereoisomers. Importers and exporters must ensure accurate analytical data to confirm that their product meets the stringent criteria for this classification.
