2921.42.10.00 - N,N-Dimethylaniline

This classification covers the specific aromatic amine N,N-Dimethylaniline. As a derivative of aniline, it is characterized by the presence of two methyl groups attached to the nitrogen atom, differentiating it from other substituted anilines. N,N-Dimethylaniline serves as a crucial intermediate in the synthesis of dyes, pharmaceuticals, and agricultural chemicals, and is also utilized as a catalyst in the production of polymers.

It is important to distinguish N,N-Dimethylaniline from its sibling categories. For instance, sibling codes like 2921.42.15.00 cover other N-alkylated anilines such as N-Ethylaniline and N,N-Diethylaniline, which have different alkyl substituents on the nitrogen atom. Other siblings may include halogenated aniline derivatives (e.g., 2,4,5-Trichloroaniline) or those with sulfonic acid functional groups (e.g., Metanilic acid, Sulfanilic acid), highlighting the specific chemical modifications that define distinct tariff headings.

As a leaf node within the HTS, 2921.42.10.00 does not have further subdivisions. Therefore, classification within this code relies solely on the accurate identification of N,N-Dimethylaniline itself, based on its chemical structure and composition, ensuring it is not misclassified with structurally similar but distinct compounds found in adjacent sibling categories.
