2928.00.25.00 - Aromatic

This HTS category, 2928.00.25.00, specifically covers **aromatic compounds that are organic derivatives of hydrazine or hydroxylamine**. These are chemical substances characterized by the presence of an aromatic ring system and a functional group derived from hydrazine (N2H4) or hydroxylamine (NH2OH). Examples include phenylhydrazine and its derivatives, as well as aromatic compounds with an -ONH2 group. These compounds often serve as intermediates in the synthesis of pharmaceuticals, dyes, and agrochemicals.

Within the broader category of "Other" organic derivatives of hydrazine or hydroxylamine, this specific subcategory is distinguished by the **aromatic nature of the parent molecule**. Other subcategories at this level might encompass aliphatic derivatives (those without aromatic rings) or salts and other simple derivatives that do not exhibit aromaticity. The presence of an aromatic ring is the key determinant for classification under 2928.00.25.00.

As this classification represents a leaf node, there are no further subdivisions. Therefore, classification into this category hinges on the direct identification of an aromatic organic compound that is a derivative of either hydrazine or hydroxylamine. Customs officers will examine the chemical structure and properties of the imported or exported substance to ensure it meets these specific criteria.
