2915.29 - Other:

This HTS category, 2915.29, encompasses various salts and derivatives of acetic acid, excluding acetic acid itself and acetic anhydride, which are classified under sibling categories 2915.21 and 2915.24 respectively. The primary distinction lies in the chemical form; this heading covers compounds where acetic acid has reacted to form salts with metals or other cations, or other derivatives not otherwise specified.

Specifically, this "Other" category serves as a residual for acetic acid derivatives that do not fit into the more specific headings for the acid or its anhydride. These products are characterized by their chemical composition, which includes the acetate radical alongside other elements or functional groups. Their physical properties and intended uses can vary widely, but their classification hinges on the presence of the acetate moiety and their exclusion from more precisely defined classifications.

Within this category, further subdivisions exist to account for specific important acetate salts. These include cupric acetate monohydrate (2915.29.10.00), sodium acetate (2915.29.20.00), and cobalt acetates (2915.29.30.00). The remaining entries fall under the "Other" subcategory (2915.29.50.00), capturing any other acetic acid salts or derivatives not explicitly listed, provided they meet the general criteria of this heading within the broader context of organic chemicals.
