2918.99.05.00 - p-Anisic acid; Clofibrate; and 3-Phenoxybenzoic acid

This HTS category, 2918.99.05.00, specifically encompasses p-Anisic acid, Clofibrate, and 3-Phenoxybenzoic acid. These are carboxylic acids featuring an additional oxygen function and are further derivatized or possess an aromatic structure. Their inclusion here is due to their specific chemical composition and functionalities, falling under the broader group of carboxylic acids with additional oxygen functions and their halogenated, sulfonated, nitrated, or nitrosated derivatives, when they are not otherwise specified.

Within this level, it's important to distinguish this entry from its siblings. For instance, HTS codes 2918.99.06.00 and 2918.99.14.00 cover distinct naphthalene carboxylic acid derivatives and phenoxypropionic acid derivatives, respectively. The "Other:" designation in this specific code signifies that p-Anisic acid, Clofibrate, and 3-Phenoxybenzoic acid do not fit into more narrowly defined sub-classifications at this point in the HTS structure, but are still characterized by their aromatic nature and the presence of a carboxylic acid group alongside other oxygen-containing functionalities.

As this is a leaf node in the HTS classification system, there are no further subcategories that subdivide the products within 2918.99.05.00. Classification is therefore definitive for these specified compounds. Practical classification relies on the precise identification of the substance as either p-Anisic acid, Clofibrate, or 3-Phenoxybenzoic acid, ensuring that these chemicals are accurately declared for customs purposes.
