2905.12.00 - Propan-1-ol (Propyl alcohol) and propan-2-ol (Isopropyl alcohol)

This HTS category, 2905.12.00, specifically covers propan-1-ol (commonly known as n-propyl alcohol) and propan-2-ol (commonly known as isopropyl alcohol). These are saturated monohydric acyclic alcohols with a three-carbon chain. Both are widely used as solvents in various industries, including pharmaceuticals, cosmetics, and printing inks, and also serve as intermediates in chemical synthesis.

This classification is distinct from its siblings, such as methanol (2905.11) and the various butanols (2905.13 and 2905.14), based on the specific number of carbon atoms in the alcohol's carbon chain. While all fall under the broader category of saturated monohydric alcohols, the precise chemical structure, characterized by the three-carbon backbone in propanols, dictates their placement within the HTS.

Further subdivision exists for this category to distinguish between the two isomers of propanol. Subcategory 2905.12.00.10 is designated for propan-1-ol, while 2905.12.00.50 is for propan-2-ol. This distinction allows for more granular tariff collection and statistical tracking, recognizing that while chemically similar, these isomers may have different purity standards, applications, or trade volumes.
