2309.90.44.90 - Other

This classification, HTS Code 2309.90.44.90, encompasses a residual category within "Other animal feeds containing milk or milk derivatives" that do not fall under the specific subheading for "Milk replacer" (2309.90.44.10). Therefore, this category is for animal feed preparations that contain milk or milk derivatives, are not milk replacers, and are entered pursuant to additional U.S. note 2 to chapter 23.

The key distinguishing factor from its sibling, "Milk replacer," is the intended primary nutritional purpose and formulation. While "Milk replacer" is specifically designed to substitute for whole milk for young animals, this residual category will include other types of animal feeds where milk or milk derivatives are an ingredient but not the sole or primary substitute for milk. Examples might include certain specialized calf starters, piglet feeds, or pet food formulations that incorporate milk-based components for palatability or nutritional enrichment.

As this is a leaf node in the HTS classification, there are no further subcategories under 2309.90.44.90. Classification within this code is contingent upon the product meeting the criteria of containing milk or milk derivatives, not being a milk replacer, and satisfying the specific entry requirements outlined in additional U.S. note 2 to chapter 23. Importers should ensure their product documentation and composition clearly demonstrate adherence to these conditions.
