Overview
This HTS category, 2905, encompasses a broad range of acyclic alcohols. Acyclic alcohols are organic compounds characterized by a hydroxyl group (-OH) attached to a carbon atom that is not part of a ring structure. This classification includes simple alcohols like methanol and ethanol, as well as more complex saturated and unsaturated alcohols. The scope also extends to derivatives of these alcohols that have been modified through the addition of halogen, sulfonic acid, nitro, or nitroso groups. These compounds find widespread applications as solvents, intermediates in chemical synthesis, and components in various industrial products.
Unlike sibling categories such as live animals or other broad classifications within the HTS, 2905 is specifically dedicated to organic chemical compounds. It is situated within Section VI, "Products of the Chemical or Allied Industries," and more narrowly within Chapter 29, "Organic chemicals," underscoring its focus on chemically defined substances rather than biological entities or finished manufactured goods. The distinction from other organic chemical categories would typically rely on the presence of the acyclic alcohol functional group and the absence of other primary defining characteristics of those categories (e.g., aldehydes, ketones, or carboxylic acids).
The subcategories within 2905 provide for a more granular classification based on the structure and functional groups present. "Saturated monohydric alcohols" refers to alcohols with a single hydroxyl group and no double or triple bonds in the carbon chain. "Unsaturated monohydric alcohols" contain at least one double or triple bond. "Diols" are alcohols with two hydroxyl groups, while "Other polyhydric alcohols" encompass those with three or more hydroxyl groups. Finally, "Halogenated, sulfonated, nitrated or nitrosated derivatives of acyclic alcohols" captures modified versions of acyclic alcohols where specific functional groups have been introduced. This subdivision allows for precise identification and duty assessment based on the specific chemical nature and complexity of the alcohol or its derivative.
