2921.42.23.00 - 3,4-Dichloroaniline

This classification covers aromatic monoamines that are derivatives of aniline and their corresponding salts. These compounds are characterized by an amino group directly attached to an aromatic ring. The scope of this category is specific to aniline derivatives, distinguishing them from other aromatic monoamines or aliphatic amines covered elsewhere in Chapter 29.

Within this category, specific isomers and substituted anilines are further delineated. For instance, while 2,4,5-trichloroaniline and various other dichloroaniline isomers are classified under sibling codes, the present code, 2921.42.23.00, specifically designates 3,4-Dichloroaniline. This precise isomer differentiation is crucial for accurate tariff application.

As a leaf node in the HTS structure, 3,4-Dichloroaniline does not have further subcategories. Its classification is therefore definitive at this level, relying on the specific chemical identity to distinguish it from other listed aniline derivatives. The primary use of 3,4-Dichloroaniline is typically as an intermediate in the synthesis of dyes, pigments, and agricultural chemicals.
