0406.90.51.00 - Described in general note 15 of the tariff schedule and entered pursuant to its provisions

This HTS classification, 0406.90.51.00, pertains to "other cheese" that is specifically described and entered according to the provisions outlined in general note 15 of the Harmonized Tariff Schedule. This category encompasses a wide array of cheeses not specifically enumerated under preceding subheadings within Chapter 4, provided they meet the criteria established by general note 15. These provisions often relate to specific production methods, aging processes, or compositional characteristics that distinguish them from more precisely defined cheese types.

Within the "Other cheese" category (0406.90), this particular subheading is distinct from its siblings, 0406.90.52.00 and 0406.90.54.00. While 0406.90.52.00 covers cheeses described in additional U.S. note 19, and 0406.90.54.00 is a residual "other" category for cheeses not otherwise specified, 0406.90.51.00 specifically relies on the detailed technical and descriptive parameters found in general note 15 for its correct classification. Therefore, to classify a cheese under this code, a thorough review of general note 15 is paramount to ensure the product's specifications align with its requirements.

As this is a leaf node, there are no further subcategories. Classification under 0406.90.51.00 is final, contingent upon meeting the criteria outlined in general note 15. Examples of cheeses that might fall under this classification, assuming they meet the general note 15 requirements, could include certain artisanal cheeses with unique aging profiles or specific ingredient inclusions that do not align with more common cheese designations. The key to accurate classification here lies in the precise interpretation and application of the rules set forth in general note 15.
