2916.34.15.00 - Odoriferous or flavoring compounds

This category encompasses phenylacetic acid and its salts that are not specifically classified elsewhere. Phenylacetic acid is an aromatic carboxylic acid with a phenyl group attached to acetic acid. Its salts include various metal or organic amine salts. These compounds can be used in a variety of applications, including as precursors in the synthesis of pharmaceuticals, in perfumery, and as flavoring agents.

Given that this is a leaf node, the primary classification consideration is to ensure the goods are indeed phenylacetic acid or its salts. If the product is a derivative where the phenylacetic acid structure has undergone further chemical modification beyond salt formation (e.g., halogenation, sulfonation), it would fall under a different HTS classification. Similarly, if the compound is merely a component within a mixture or a formulated product, the classification would depend on the specific nature of the mixture or formulation.

The "Other" designation at this level signifies that this subcategory captures all phenylacetic acid and its salts not explicitly detailed by a more specific HTS code. Therefore, a thorough examination of the product's chemical identity and composition is crucial for accurate classification under this heading.
