0406.90.41.00 - Described in additional U.S. note 21 to this chapter and entered pursuant to its provisions

This classification, HTS Code 0406.90.41.00, specifically designates "Romano made from cow's milk, Reggiano, Parmesan, Provolone and Provoletti cheeses" when they are described in additional U.S. note 21 to Chapter 4 and entered pursuant to its provisions. These are hard, aged cheeses with distinct flavor profiles and textures, typically used in culinary applications. The inclusion of "made from cow's milk" is a critical component for classification under this code, distinguishing them from similar cheeses produced from other animal milks.

This specific subcategory is differentiated from its sibling, 0406.90.42.00, which covers "Other" cheeses within the broader "Other cheese" category. While 0406.90.42.00 acts as a residual category for cheeses not explicitly listed or defined elsewhere at this level, 0406.90.41.00 is highly specific, encompassing only a defined list of Italian-style cheeses produced from cow's milk. The emphasis here is on the precise identification of these well-known cheese types.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Classification at this level is definitive and relies on the importer accurately identifying the product as one of the specified cheeses (Romano, Reggiano, Parmesan, Provolone, or Provoletti) and confirming it is made from cow's milk, in addition to meeting the requirements of additional U.S. note 21.
