2309.90.24.90 - Other

This HTS subheading, 2309.90.24.90, encompasses "Other" preparations used in animal feeding that are not specifically classified under the "Milk replacer" category. These products are characterized by their inclusion of milk or milk derivatives and contain over 10 percent by weight of milk solids. Crucially, for classification under this specific subheading, the goods must also be described in Additional U.S. Note 2 to Chapter 23 and entered in accordance with its provisions.

The primary distinction between this category and its sibling, 2309.90.24.10 (Milk replacer), lies in the specific intent and formulation. While both contain milk solids and are for animal feed, "Milk replacer" is typically designed to substitute for whole milk, often for very young animals. This "Other" category would include a broader range of preparations where milk solids are a significant component but not necessarily the sole or primary replacement for milk, and the specific conditions of Additional U.S. Note 2 are met.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, accurate classification relies on a thorough understanding of the definition of "milk solids" as it pertains to this chapter and a precise adherence to the requirements outlined in Additional U.S. Note 2 to Chapter 23. Examples might include specialized feed supplements or pre-mixes for livestock or poultry that leverage the nutritional benefits of milk derivatives but are not formulated as direct milk substitutes.
