2309.90.28 - Other

This HTS category, 2309.90.28, encompasses "Other" preparations for animal feeding that are not specifically enumerated under sibling subheadings. These are typically complex mixtures or preparations used to supplement or wholly provide nutrition for animals, and fall outside of more precisely defined categories within the "Other" preparations of a kind used in animal feeding. The key characteristic is their role as a feed additive or complete feed for animals, but their specific composition or intended use does not align with the more detailed classifications.

It is crucial to distinguish this subheading from its siblings, 2309.90.22 and 2309.90.24. Subheading 2309.90.22 covers goods that are specifically described in general note 15 of the tariff schedule and entered under its provisions, often relating to specific trade agreements or preferential treatments. Similarly, 2309.90.24 is reserved for items described in additional U.S. note 2 to this chapter and entered pursuant to its provisions, typically involving specific U.S. regulations or import requirements. This subheading, 2309.90.28, serves as a residual category for products that do not meet the specific criteria for those other subheadings.

Within this "Other" category, two subcategories exist to further refine classification. 2309.90.28.10 specifically identifies "Milk replacer," which are formulated to substitute for natural milk in the feeding of young animals. All other preparations that meet the broader criteria of 2309.90.28 but are not milk replacers are classified under 2309.90.28.90, designated as "Other." This hierarchical structure ensures that even within this broad residual classification, a more precise categorization is applied based on the primary function of the animal feed preparation.
