0406.20.51.00 - Described in additional U.S. note 21 to this chapter and entered pursuant to its provisions

This HTS category, 0406.20.51.00, specifically covers grated or powdered cheese that is described in additional U.S. note 21 to Chapter 4 and entered pursuant to its provisions. This designation indicates that the cheese, when presented in grated or powdered form, meets particular criteria outlined in the note. These cheeses are generally hard varieties that are suitable for grating or powdering.

Within the broader category of grated or powdered cheese, this subcategory distinguishes itself from its sibling, 0406.20.53.00, which is designated as "Other." While 0406.20.51.00 is reserved for specific cheeses that qualify under additional U.S. note 21, the "Other" category would encompass any other grated or powdered cheeses not meeting those precise specifications. The key differentiator lies in the explicit reference to the additional U.S. note for the classification of goods under 0406.20.51.00.

As this is a leaf node in the HTS classification system, there are no further subcategories. Therefore, the focus for classification within 0406.20.51.00 rests entirely on whether the grated or powdered cheese meets the specific requirements stipulated in additional U.S. note 21 and is entered in accordance with its provisions. This note is critical for determining the correct classification for these particular types of grated or powdered cheeses.
