0403.90.90.00 - Described in additional U.S. note 10 to this chapter and entered pursuant to its provisions

This HTS classification, 0403.90.90.00, pertains to yogurt, buttermilk, curdled milk and cream, kephir, and other fermented or acidified milk and cream that meet specific criteria outlined in additional U.S. note 10 to Chapter 4. These products, which may be concentrated, contain added sugar, sweeteners, flavors, fruits, nuts, or cocoa, are distinguished by their specific entry provisions.

At this level within the "Other" category for fermented milk products, this subheading is distinct from its sibling, 0403.90.87.00, which covers similar products that are entered pursuant to general note 15 of the tariff schedule. Therefore, the critical differentiator for classification under 0403.90.90.00 lies in adherence to the specific requirements and provisions set forth in additional U.S. note 10.

As this is a leaf node, there are no further subcategories. Classification within 0403.90.90.00 is therefore final and depends entirely on whether the imported product satisfies the conditions detailed in the referenced additional U.S. note. Importers should carefully review the text of additional U.S. note 10 to ensure correct classification.
