0406.20.31 - Described in additional U.S.note 18 to this chapter and entered pursuant to its provisions

This HTS classification, 0406.20.31, specifically covers grated or powdered Cheddar cheese that meets the conditions outlined in additional U.S. note 18 to Chapter 4. This note likely details specific requirements, such as ingredient composition, production methods, or intended use, which differentiate these cheeses from others classified under the broader "grated or powdered cheese" heading. The focus here is on Cheddar cheese that has been processed into a grated or powdered form and satisfies these particular U.S. provisions.

To distinguish this category from its siblings, 0406.20.29.00 and 0406.20.33.00, it's important to note that 0406.20.29.00 applies to grated or powdered cheese described in general note 15, suggesting a different set of governing provisions or origins. The sibling category 0406.20.33.00, labeled "Other," encompasses any grated or powdered Cheddar cheese that does not fall under the specific provisions of 0406.20.31 or 0406.20.29.00. Therefore, 0406.20.31 is for a precisely defined subset of grated or powdered Cheddar cheese.

This classification is further divided into two subcategories to account for variations in origin and potential trade regulations. Subcategory 0406.20.31.10 is designated for Cheddar cheese that has been produced in Canada and is not subject to specific licensing requirements. Conversely, 0406.20.31.90 serves as a residual category for all other grated or powdered Cheddar cheese that meets the conditions of additional U.S. note 18 but does not originate from Canada under the specified licensing exemption. This breakdown allows for granular tracking of trade flows and adherence to bilateral agreements or specific import controls.
