2309.90.22.10 - Milk replacer

This HTS category, 2309.90.22.10, specifically covers "Milk replacer." These are preparations designed to substitute for natural milk, primarily for feeding young animals, such as calves or piglets, during periods when natural milk is unavailable or insufficient. The composition typically includes various protein sources, fats, carbohydrates, vitamins, and minerals, formulated to mimic the nutritional profile of milk.

Within the broader category of "Animal feeds containing milk or milk derivatives," this sub-sub-category distinguishes itself by focusing on direct milk replacements. It is differentiated from its sibling category, 2309.90.22.90 "Other," which would encompass other animal feed preparations containing milk or milk derivatives that do not specifically function as a primary milk substitute or meet the specific criteria of this entry.

As this is a leaf node, there are no further subcategories to introduce. The classification for milk replacers under this code is based on their specific function as a complete nutritional substitute for milk for young animals and their formulation to meet those specific dietary needs, often in powder or liquid form for reconstitution.
