2906.19 - Other:

This HTS classification, 2906.19, covers "Other" cyclic alcohols and their derivatives that do not fall under the more specific subheadings of this group. It pertains to organic chemical compounds that are characterized by ring structures (cyclanic, cyclenic, or cycloterpenic) and contain an alcohol functional group, or are halogenated, sulfonated, nitrated, or nitrosated derivatives thereof. The scope of this category is broad, encompassing a variety of cyclic alcohol compounds not otherwise specified.

Within the broader category of cyclic alcohols, 2906.19 distinguishes itself from its siblings by excluding specific, well-defined compounds. For instance, it is separate from 2906.11.00.00 (Menthol), 2906.12.00.00 (Cyclohexanol, methylcyclohexanols and dimethylcyclohexanols), and 2906.13 (Sterols and inositols). These sibling categories are reserved for the precise identification of these particular types of cyclic alcohols, meaning 2906.19 captures those that do not precisely match the chemical structures or common names defined in those other headings.

The subcategories within 2906.19 further refine the classification for specialized cyclic alcohol derivatives. This includes 2906.19.10.00, which specifically addresses certain isopropylidene derivatives and stereoisomers of isopropyl-methylcyclohexanol. Additionally, 2906.19.30.00 is designated for Terpineols, another distinct group of cycloterpenic alcohols. The residual category, 2906.19.50.00, serves as a catch-all for any remaining cyclic alcohols and their specified derivatives that do not meet the criteria for the more granular subheadings within 2906.19 or any preceding headings.
