2905.22.50.50 - Other

This classification covers acyclic terpene alcohols that do not fit into more specific subheadings within this group. Terpene alcohols are organic compounds derived from isoprene units, characterized by their cyclic or acyclic structures and the presence of at least one hydroxyl (-OH) functional group. This specific subheading is for those acyclic terpene alcohols that are not otherwise enumerated or specifically defined elsewhere.

Distinguishing this category from its sibling, 2905.22.50.10 (Citronellol), is crucial. Citronellol is a specific acyclic terpene alcohol with a defined chemical structure and characteristic rose-like scent, often used in perfumery and flavoring. This "Other" category, therefore, encompasses all acyclic terpene alcohols that lack the specific identity or common use of citronellol, meaning they are not chemically identical or primarily recognized as such.

As this is a leaf node, there are no further subcategories. Classification under this heading is determined by the absence of specific structural features or common market recognition that would warrant placement in a more granular subheading. Importers and exporters must ensure that the acyclic terpene alcohol in question does not possess the definitive characteristics of any other enumerated terpene alcohol, particularly citronellol, before assigning it to this residual classification.
