0406.90.39.00 - Described in general note 15 of the tariff schedule and entered pursuant to its provisions

This classification covers specific hard Italian-style cheeses that are not otherwise specified. It includes cheeses like Romano, Reggiano, Parmesan, Provolone, and Provoletti, provided they are made from cow's milk and meet the criteria outlined in general note 15 of the Harmonized Tariff Schedule. These cheeses are characterized by their firm texture, often crumbly nature when aged, and distinctive sharp, salty, or nutty flavors, making them suitable for grating, cooking, or consumption on their own.

While the broader category "Other cheese" encompasses a vast array of dairy products, this subcategory drills down into a particular family of cheeses with established culinary uses and production methods. The sibling category, "Other," would capture any cheeses not fitting the specific profiles of hard Italian-style cheeses or other designated categories within 0406.90.39. The absence of further subcategories indicates that this is a terminal classification, meaning that the cheeses falling under this code are not further broken down by specific types within Romano, Reggiano, Parmesan, Provolone, or Provoletti; rather, they are grouped together as a distinct set of Italian hard cheeses.
