2915.24.00.00 - Acetic anhydride

This category, HTS 2915.24.00.00, specifically covers acetic anhydride. Acetic anhydride is an organic chemical compound with the formula (CH₃CO)₂O. It is a reactive acylating agent and a key intermediate in many industrial processes, particularly in the production of cellulose acetate for films and fibers, as well as pharmaceuticals and dyes. Its classification here is driven by its chemical structure and function as an anhydride of acetic acid.

This classification is distinct from its sibling category, 2915.21.00.00, which covers acetic acid itself. While acetic acid is a precursor to acetic anhydride, this code is exclusively for the anhydride form, characterized by the presence of two acetyl groups linked by an oxygen atom. This difference in chemical structure and reactivity is the primary basis for their separate classifications.

As a leaf node in the Harmonized Tariff Schedule, 2915.24.00.00 does not have further subdivisions. Therefore, classification within this code is solely determined by whether the imported or exported good is indeed acetic anhydride. Specific classification will rely on product specifications, chemical analysis certificates, and customs declarations confirming the identity and purity of the substance as acetic anhydride, as defined by its chemical properties and common industrial uses.
