This HTS subcategory, 2922.29.10.00, encompasses a specific range of amino-phenolic compounds. These are characterized by the presence of both an amino group and a hydroxyl group attached to a phenolic ring, with the exclusion of multiple oxygen-containing functional groups beyond ether or ester linkages. The listed substances, such as 2-Amino-6-chloro-4-nitrophenol and m-Aminophenol, are primarily utilized as intermediates in the synthesis of dyes, pigments, pharmaceuticals, and other organic chemicals. Classification within this heading hinges on the precise chemical structure and the absence of more complex oxygen functionalities.

Distinguishing this category from its siblings involves a careful examination of the substituents on the phenolic ring and the nature of any ether or ester groups. For instance, sibling categories may cover simpler anisidines or phenetidines (2922.29.03.00), or compounds with different arrangements of amino and hydroxyl groups or additional substituents like halogens or nitro groups that place them in separate headings or subheadings. The presence of specific nitro or chloro substituents, as seen in many entries here, is a key differentiator.

As this subcategory is a leaf node, there are no further subdivisions. Classification within 2922.29.10.00 is therefore definitive based on the precise chemical identity of the imported substance matching one of the enumerated compounds or their salts. The inclusion of specific salts, such as 2-Amino-4-nitrophenol, sodium salt, highlights the importance of considering salt forms within this classification.
