2916.31.11.05 - Benzoic acid

This HTS category encompasses pure benzoic acid, a fundamental aromatic carboxylic acid characterized by its benzene ring substituted with a carboxyl group. It serves as a key intermediate in the synthesis of various organic compounds, including plastics, pharmaceuticals, and flavorings. Classification under this heading is determined by the chemical identity of the substance as benzoic acid itself, free from salts or esterification.

Distinguishing this category from its siblings is crucial for accurate classification. The sibling category 2916.31.11.70 specifically covers sodium benzoate, which is the sodium salt of benzoic acid and is commonly used as a preservative. The sibling category 2916.31.11.90 encompasses "Other" benzoic acid derivatives at this level, which would include other salts or potentially other simple derivatives not otherwise specified. Therefore, this specific node is reserved for benzoic acid in its unassociated acid form.

As this is a leaf node, there are no further subcategories. Classification at this level relies solely on the identification of the substance as benzoic acid itself, as opposed to its salts or esters. This distinction is vital as different forms of benzoic acid may have different tariff treatments and regulatory requirements.
