2935.90.10.00 - 2-Amino-N-ethylbenzenesulfonanilide; 5-Amino-α,α,α-trifluorotoluene-2,4-disulfonamide; Benzenesulfonamide; Benzenesulfonyl hydrazide; 2-Chloro-4-amino-5-hydroxybenzenesulfonamide; 2,5-Dimethoxysulfanilanilide; and Metanilamide

This HTS category, 2935.90.10.00, encompasses a specific group of benzenesulfonamide derivatives and related compounds that do not fall under more precisely defined sibling categories. These substances are characterized by their sulfonamide functional groups and often feature various substitutions on the benzene ring or amine groups, imparting distinct chemical properties and potential applications. Examples include 2-Amino-N-ethylbenzenesulfonanilide, 5-Amino-α,α,α-trifluorotoluene-2,4-disulfonamide, Benzenesulfonamide, Benzenesulfonyl hydrazide, 2-Chloro-4-amino-5-hydroxybenzenesulfonamide, 2,5-Dimethoxysulfanilanilide, and Metanilamide.

Distinguishing this category from its siblings is crucial for accurate classification. Unlike 2935.90.06.00, which specifically enumerates 4-Amino-6-chloro-m-benzenedisulfonamide and Methyl-4-aminobenzenesulfonylcarbamate (Asulam), or 2935.90.13.00, which lists a variety of complex sulfonamide compounds including herbicides and amides, this particular code is for other, less specifically detailed sulfonamides. Furthermore, it differs from 2935.90.15.00, which is solely dedicated to o-Toluenesulfonamide. The "Other" designation signifies that any benzenesulfonamide derivative or related compound not explicitly listed or covered by the more specific sibling codes will be classified here.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. The classification process for goods falling under 2935.90.10.00 relies on a thorough examination of the chemical identity and the absence of the specific characteristics that would warrant classification under any of the more narrowly defined sibling codes. This ensures that all remaining benzenesulfonamide compounds are appropriately accounted for within Chapter 29.
