2935.90.60.00 - Other

This HTS category, 2935.90.60.00, encompasses sulfonamides that are not specifically classified under other headings within Chapter 29. It serves as a residual category for various sulfonamide compounds and their derivatives, provided they are not intended for direct medicinal use as finished drugs. Examples may include sulfonamide intermediates used in the synthesis of pharmaceuticals or other chemical products, or sulfonamide-based compounds with applications in industrial processes.

Distinguishing this category from its sibling, "Anti-infective agents," is crucial. While both fall under sulfonamides, this category excludes compounds explicitly designed and marketed as medications for combating infections. The sibling category focuses on sulfonamides with a primary therapeutic purpose, whereas 2935.90.60.00 captures sulfonamides whose utility lies in their chemical structure or as building blocks for other industries, rather than direct pharmacological action.

As this node represents a leaf category, there are no further subcategories to introduce. Classification within this heading is determined by the absence of a more specific classification elsewhere in the HTS, particularly for sulfonamides that do not meet the criteria for anti-infective agents or other defined chemical uses. The importer bears the responsibility of ensuring that the goods do not fit into more precisely defined categories before classifying them here.
