2309.90.44.10 - Milk replacer

This HTS code, 2309.90.44.10, specifically classifies "Milk replacer" within the broader category of "Preparations of a kind used in animal feeding." Milk replacers are designed as a substitute for natural milk, typically for young mammals such as calves, piglets, or lamb. These products are formulated to provide essential nutrients, including proteins, fats, vitamins, and minerals, mimicking the nutritional profile of mother's milk to support growth and development during early life stages.

Within the "Animal feeds containing milk or milk derivatives" grouping, this subcategory is distinguished from its sibling, 2309.90.44.90 (Other), by its primary function as a complete milk-substitute feed. While other entries might contain milk derivatives as an ingredient, 2309.90.44.10 is exclusively for preparations specifically engineered to replace natural milk in the diet of young animals. The classification hinges on the product's intended use and formulation as a primary, sole source of nutrition for weaned or orphaned young animals.

As this is a leaf node within the HTS, there are no further subcategories. Therefore, classification under 2309.90.44.10 is definitive for products meeting the description of milk replacer that are also described in additional U.S. note 2 to this chapter and are entered pursuant to its provisions. Importers should ensure that the product's composition, labeling, and intended use align precisely with the definition of a milk replacer to qualify for this specific classification.
