2309.90.24 - Described in additional U.S. note 2 to this chapter and entered pursuant to its provisions

This HTS category, 2309.90.24, specifically covers prepared animal feeds that are derived from milk or milk derivatives and contain a significant milk solids content. To fall under this classification, the product must contain over 10 percent by weight of milk solids, ensuring a substantial portion of its composition originates from milk. This category is designated for products that meet these precise compositional requirements and are entered under the provisions outlined in additional U.S. note 2 to Chapter 23.

When distinguishing this category from its siblings, it's crucial to note that 2309.90.22 applies to animal feeds described in general note 15, which may have different compositional or entry requirements. Category 2309.90.28, "Other," serves as a residual category for milk-derived animal feeds that do not meet the specific criteria of 2309.90.24. The defining factor for 2309.90.24 is the explicit over 10 percent by weight milk solids requirement, setting it apart from broader or more general classifications.

Within this category, two subcategories further refine the classification. 2309.90.24.10 is designated for "Milk replacer," a specific type of feed designed to substitute for whole milk, often for young animals. The residual subcategory, 2309.90.24.90, encompasses all other animal feeds that meet the primary criteria of containing over 10 percent milk solids but do not qualify as milk replacer, providing a comprehensive classification for these milk-based animal feed preparations.
