2916.34.55.00 - Other

This HTS category, HTS 2916.34.55.00, encompasses "Other" aromatic monocarboxylic acids, their anhydrides, halides, peroxides, peroxyacids, and their derivatives, specifically falling under the subheading for phenylacetic acid and its salts, when they do not meet the criteria of the preceding subheadings. This residual classification is for substances within this broad group that are not otherwise specifically provided for.

It is crucial to distinguish this category from its sibling, HTS 2916.34.25.00, which covers products described in additional U.S. note 3 to section VI. This sibling category requires a specific interpretation based on that particular U.S. note, likely pertaining to specific uses or forms of these chemicals. If a product falls under that additional U.S. note, it will be classified there and not in this "Other" category.

As this is a leaf node within the HTS, there are no further subcategories. Therefore, classification into HTS 2916.34.55.00 is dependent on the careful exclusion of all more specific classifications. Importers and customs brokers must thoroughly examine the chemical identity and properties of the product, comparing it against all preceding HTS codes within the 2916.34.00 range, to ensure correct classification in this residual category. This requires a comprehensive understanding of aromatic monocarboxylic acid derivatives and their common commercial forms.
