2905.14.50 - Other

This HTS category, 2905.14.50, encompasses "Other" butanols and their derivatives. Specifically, it covers saturated monohydric acyclic alcohols that are isomers of butanol but do not fall under more precisely defined subheadings at this level. This classification acts as a residual category for butanol isomers not explicitly listed elsewhere within the 2905.14 subheading.

Within the context of "Other butanols," this category is distinguished from its sibling, 2905.14.10.00, which specifically covers tert-Butyl alcohol with a purity of less than 99 percent by weight. Therefore, 2905.14.50 is for butanol isomers that are not tert-Butyl alcohol (or are tert-Butyl alcohol with a purity of 99 percent or more, though these would likely fall under a more specific classification if available at a higher level), or are other butanol isomers not otherwise specified.

The subcategories under 2905.14.50 provide further refinement for the types of "Other" butanols. 2905.14.50.10 is designated for 2-Methylpropan-1-ol, commonly known as Isobutyl alcohol. The remaining butanol isomers not classified as isobutyl alcohol will be found under 2905.14.50.50, "Other," serving as the final residual category for this group of alcohols.
