2935.90.75.00 - Products described in additional U.S. note 3 to section VI

This HTS category, 2935.90.75.00, encompasses sulfonamides that do not fall under any more specific subheading within heading 2935. The defining characteristic for classification under this code is that these products must be "described in additional U.S. note 3 to section VI." This additional U.S. note provides specific guidance and exclusions relevant to the classification of chemicals within Section VI of the Harmonized Tariff Schedule.

Distinguishing this category from its sibling, 2935.90.95.00 ("Other"), is crucial. While both are designated as "other" within their respective hierarchies, the presence of the explicit reference to "additional U.S. note 3 to section VI" creates a distinct classification rule. Imports classified under 2935.90.75.00 must meet the criteria outlined in that specific U.S. note, which may involve specific chemical structures, intended uses, or trade restrictions not applicable to the broader "other" category.

As this is a leaf node, there are no further subcategories to introduce. Therefore, the classification of goods under 2935.90.75.00 relies heavily on a thorough understanding of the definitions and stipulations found within additional U.S. note 3 to section VI. Importers and customs brokers must carefully review this note to ensure that their sulfonamide products meet the outlined requirements for accurate classification.
