2921.43.04.00 - 3-Chloro-o-toluidine; and 6-Chloro-o-toluidine

This HTS classification encompasses specific chlorinated derivatives of ortho-toluidine, namely 3-Chloro-o-toluidine and 6-Chloro-o-toluidine. These are aromatic amines characterized by the presence of a methyl group and a chlorine atom attached to the benzene ring, with the amino group also directly bonded to the ring. Their primary utility lies as intermediates in the synthesis of dyes, pigments, pharmaceuticals, and agricultural chemicals.

Distinguishing this category from its siblings is crucial for accurate classification. For instance, sibling category 2921.43.08.00 covers a broader array of chlorinated and trifluoromethylated toluidines, as well as N-substituted toluidines and sulfonic acid derivatives, indicating a wider range of substituents and structural modifications. Other siblings, such as 2921.43.15.00 and 2921.43.22.00, are specifically dedicated to complex dinitro compounds like Trifluralin and related trifluoromethylated benzenamines, highlighting significant differences in chemical structure and intended use. This current category is narrowly defined by the specific positions of the chlorine atom relative to the methyl and amino groups on the toluidine structure.

As this is a leaf node, there are no further subcategories. Classification within 2921.43.04.00 is determined by the precise chemical identity of the imported substance matching either 3-Chloro-o-toluidine or 6-Chloro-o-toluidine. Proper identification and documentation are therefore essential to ensure correct tariff treatment under this specific heading.
