2905.22 - Acyclic terpene alcohols:

This HTS category, 2905.22, encompasses acyclic terpene alcohols. These are organic compounds characterized by an open chain structure and the presence of at least one hydroxyl group (-OH), along with a terpene skeleton. Terpenes are a large and diverse class of organic compounds produced by a variety of plants, particularly conifers. Acyclic terpene alcohols, therefore, are unsaturated monohydric alcohols that possess a non-cyclic terpene base. Examples of uses for these compounds include their application as fragrance and flavor ingredients, as intermediates in the synthesis of other complex organic chemicals, and in certain pharmaceutical preparations.

This classification is distinct from its sibling category, 2905.29 ("Other"), which covers acyclic unsaturated monohydric alcohols that do not fit the specific definition of acyclic terpene alcohols. While both fall under the broader heading of unsaturated monohydric alcohols, 2905.22 is reserved for those with a confirmed terpene structure, a characteristic that dictates specific chemical properties and often influences their intended uses. The classification hinges on the presence of the terpene moiety within the acyclic alcohol structure.

The subcategories within 2905.22 provide further refinement based on specific, commonly traded acyclic terpene alcohols, and a residual category for others. Specifically, 2905.22.10.00 covers geraniol, a widely used fragrant acyclic terpene alcohol. Isophytol is classified under 2905.22.20.00, a key intermediate in the synthesis of Vitamin E. The remaining acyclic terpene alcohols not specifically enumerated are captured under the residual category 2905.22.50, ensuring comprehensive coverage of all goods within this scope.
