2917.19.17.00 - Other

This HTS category, 2917.19.17.00, covers "Other" acyclic polycarboxylic acids, their anhydrides, halides, peroxides, peroxyacids, and their derivatives. Crucially, this designation applies to those products not specifically enumerated in prior subheadings within the 2917.19 classification. It serves as a residual category for acyclic polycarboxylic acids and their related compounds that do not fall under the more specific classifications, such as those derived wholly or in part from aromatic hydrocarbons.

The primary distinction of this "Other" category lies in its exclusion of fumaric acid that is derived from aromatic hydrocarbons, which is classified under 2917.19.15.00. Therefore, goods classified here are acyclic polycarboxylic acids and their derivatives that are *not* of aromatic origin, and are not otherwise specifically provided for.

As this is a leaf node in the HTS classification, there are no further subcategories. Classification within 2917.19.17.00 is determined by identifying acyclic polycarboxylic acids, their anhydrides, halides, peroxides, peroxyacids, and their derivatives that do not meet the criteria for any preceding subheading within this chapter, particularly excluding those derived from aromatic hydrocarbons.
