0406.10.24.00 - Described in additional U.S. note 18 to this chapter and entered pursuant to its provisions

This HTS category, 0406.10.24.00, specifically classifies Cheddar cheese and any cheese or substitutes for cheese that contain or are processed from Cheddar cheese. The key identifier here is the presence of Cheddar cheese as a primary ingredient or as a processing component, distinguishing it from other fresh cheeses. This classification applies to products that meet the requirements of additional U.S. note 18 to Chapter 4.

Unlike the "Other" subcategory at this level (0406.10.28.00), which would encompass fresh cheeses and curd not specifically identified as Cheddar, this heading is reserved for products where Cheddar cheese is the defining characteristic. It captures the essence of Cheddar's flavor profile, texture, and origin, whether it is in its fresh, unripened state or has undergone further processing while retaining its Cheddar identity.

As this is a leaf node within the HTS structure, there are no further subdivisions under 0406.10.24.00. Therefore, the classification decision hinges entirely on whether the imported product qualifies as Cheddar cheese or a derivative thereof, as defined by relevant customs regulations and trade standards, and complies with the provisions outlined in the specified U.S. note.
