2905.14.50.10 - 2-Methylpropan-1-ol (Isobutyl alcohol)

This HTS category, 2905.14.50.10, specifically classifies 2-Methylpropan-1-ol, also commonly known as isobutyl alcohol. It falls under the broader heading of saturated monohydric alcohols, which are organic compounds characterized by a single hydroxyl (-OH) group attached to a saturated carbon atom. Isobutyl alcohol is a four-carbon alcohol with a branched structure, distinguishing it from other butanol isomers.

Within the "Other butanols" classification, this particular subcategory differentiates 2-methylpropan-1-ol from other isomers of butanol. While other four-carbon alcohols might exist and could potentially fall under related HTS codes, the explicit naming and structure of isobutyl alcohol place it firmly within this specific tariff line. The "Other" designation at the higher level (2905.14.50) indicates that this is a specific butanol isomer not otherwise enumerated.

As this is a leaf node in the HTS classification system, there are no further subcategories. Therefore, the primary classification criteria revolve around the chemical identity and structure of 2-methylpropan-1-ol itself. This classification is crucial for accurately identifying and duty-assessing shipments containing pure isobutyl alcohol or mixtures where it is the principal component.
