2935.90.95.00 - Other

This HTS category, 2935.90.95.00, encompasses a residual group of sulfonamides not specifically enumerated elsewhere within heading 2935. It serves as a catch-all for organic compounds containing the sulfonamide functional group (-SO₂NH₂) that do not fall under more specific subheadings. The classification hinges on the absence of specific characteristics or compositions that would warrant placement in a more precisely defined category.

Distinguishing this category from its sibling, 2935.90.75.00 ("Products described in additional U.S. note 3 to section VI"), is crucial. While both fall under the broader "Other" classification for sulfonamides, the sibling category is specifically reserved for products designated by a particular additional U.S. note, often pertaining to certain regulatory or trade policy considerations. Therefore, 2935.90.95.00 applies to any other sulfonamide not meeting that specific additional U.S. note criterion.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification within 2935.90.95.00 requires a thorough examination to confirm that the substance is indeed a sulfonamide and does not fit any more granular classification, including those for specific therapeutic uses or other structural classifications if provided for elsewhere within Chapter 29.
