0404.90.70.00 - Other

This HTS classification, 0404.90.70.00, pertains to "Other" whey products and natural milk constituents that do not fit into more specifically defined categories within Chapter 4. It serves as a residual category for milk-derived substances not elsewhere classified, encompassing items that are essentially natural milk constituents but are not liquid milk, cream, butter, cheese, or specific milk powders. The key defining characteristic is that these products are derived from milk but fall outside the more common and distinct classifications.

Distinguishing this category from its sibling, "Dairy products described in additional U.S. note 1 to chapter 4," is crucial for accurate classification. While both relate to milk products, the sibling category is reserved for those explicitly recognized by additional U.S. notes, which often delineate specific compositions or intended uses. This "Other" category captures a broader range of milk constituents that may not meet the specific criteria outlined in those additional notes, yet are clearly derived from milk.

As this is a leaf node, there are no further subcategories. Therefore, classification into 0404.90.70.00 relies on a thorough examination of the product to ensure it is indeed a natural milk constituent, not concentrated or sweetened in a way that would place it elsewhere, and that it does not qualify for any more specific HTS classification within Chapter 4 or other relevant chapters. Examples might include certain protein isolates derived from milk that do not meet the precise definitions of milk powders or other specified products.
