2916.39.03.00 - Benzoic anhydride;tert-Butyl peroxybenzoate;p-Nitrobenzoyl chloride; 2-Nitro-m-toluic acid; and 3-Nitro-o-toluic acid

This HTS category, 2916.39.03.00, encompasses a specific group of aromatic carboxylic acid derivatives. It covers benzoic anhydride, a compound formed by the dehydration of benzoic acid, and tert-butyl peroxybenzoate, an organic peroxide used as a polymerization initiator. Additionally, it includes nitro-substituted aromatic compounds such as p-nitrobenzoyl chloride, 2-nitro-m-toluic acid, and 3-nitro-o-toluic acid, which are characterized by the presence of a nitro group (-NO2) attached to the aromatic ring and a carboxylic acid derivative functional group.

Distinguishing this category from its siblings, such as 2916.39.04.00 (which includes m-chloroperoxybenzoic acid and p-sulfobenzoic acid, potassium salt) or 2916.39.06.00 (cinnamic acid), relies on the precise chemical structure and functional groups present. For instance, while other siblings may also be aromatic carboxylic acid derivatives, they may possess different halogen, sulfur, or specific unsaturated chain substituents, or be distinct compounds like Ibuprofen. This code specifically isolates the listed anhydrides, peroxides, acid halides, and nitro-substituted toluic and benzoic acids.

As a leaf node, 2916.39.03.00 does not have further subcategories. Therefore, classification into this specific code relies on the definitive identification of the named substances. Importers and exporters must ensure that the goods precisely match the chemical names provided within this description. The presence of the anhydride, peroxy ester, acyl halide, or nitro-toluic acid functional groups, in conjunction with the aromatic benzoic or toluic acid structure, is the primary determinant for classification under this heading.
