2905.19.90.90 - Other

This HTS category, 2905.19.90.90, serves as a residual classification for acyclic, saturated monohydric alcohols that are not specifically enumerated elsewhere within the 2905.19 subheading. It encompasses a wide array of simple alcohols characterized by a single hydroxyl group (-OH) attached to a saturated acyclic carbon chain, where the specific chemical structure or isomer does not warrant a more particular tariff line. The scope is broad, including common industrial solvents, intermediates in chemical synthesis, and components in various formulations, provided they meet the general criteria of saturated monohydric acyclic alcohols.

The distinction from sibling categories is crucial for accurate classification. For instance, while this category captures "other" alcohols, sibling entries like 2905.19.90.05 for 3,3-Dimethylbutan-2-ol (pinacolyl alcohol), 2905.19.90.10 for decyl alcohol and its isomers, and 2905.19.90.20 for hexyl alcohol and its isomers, cover specific, named alcohols. Therefore, if a particular saturated monohydric acyclic alcohol is explicitly listed in a sibling category, it must be classified thereunder, and this residual category should only be utilized when no other specific provision applies.

As a leaf node in the Harmonized Tariff Schedule, this category has no further subcategories. Classification within 2905.19.90.90 is final at this level, meaning goods falling into this residual "other" classification will not be broken down into more specific tariff lines. Consequently, thorough examination of the chemical identity and properties of the alcohol in question is paramount to ensure it does not inadvertently fit into a more specific, pre-defined category within the broader 2905.19 classification.
