0406.20.77.00 - Described in additional U.S. note 21 to this chapter and entered pursuant to its provisions

This HTS category, 0406.20.77.00, specifically covers grated or powdered cheeses that are characterized by their inclusion of, or processing from, specific Italian-type cheeses made from cow's milk. This includes well-known varieties such as Romano, Reggiano, Parmesan, Provolone, Provoletti, Sbrinz, and Goya. The key defining factor for classification under this subheading is the presence or origin of these particular Italian cheese types within the grated or powdered product.

The distinction between this category and its sibling, 0406.20.79.00 ("Other"), lies in the explicit reference to the Italian-type cheeses. While the "Other" sibling would encompass grated or powdered cheeses not meeting the specific criteria of Italian-type cheeses, this subheading is precisely for those products that do. This classification is therefore highly dependent on the composition and origin of the cheese ingredients.

As this is a leaf node within the HTS, there are no further subcategories. Classification decisions at this level hinge on verifying the presence of the enumerated Italian-type cow's milk cheeses. Importers and customs brokers should consult additional U.S. note 21 to Chapter 4 for detailed provisions and requirements related to the entry of goods under this specific tariff code.
