2921.49.15.00 - m-Nitro-p-toluidine

This classification, HTS Code 2921.49.15.00, specifically covers m-Nitro-p-toluidine. As an aromatic monoamine derivative, it falls within the broader category of aromatic monoamines and their derivatives. The inclusion here signifies that m-Nitro-p-toluidine possesses both an amine functional group and an aromatic ring structure, with a nitro group and a methyl group attached to the benzene ring in a specific orientation (meta for the nitro group and para for the methyl group relative to the amine).

Distinguishing this particular entry from its siblings, the category 2921.49.10.00 encompasses a diverse group of aromatic amines, including substituted anilines and xylidines. While all are aromatic monoamines, m-Nitro-p-toluidine is a distinct chemical entity not listed within that more specific enumeration. The "Other" designation at this level serves as a catch-all for aromatic monoamines and their derivatives that do not fit into the more explicitly defined subcategories, provided they meet the general criteria of the parent heading.

As this node is a leaf node, there are no further subcategories. The classification concludes with the specific identification of m-Nitro-p-toluidine. This means that any product solely consisting of m-Nitro-p-toluidine, without further processing or admixture that would alter its fundamental classification, would be assigned this HTS code. The key for classification at this level is the precise chemical identity of the substance.
