0404.90.10.00 - Milk protein concentrates

This HTS category, 0404.90.10.00, specifically covers milk protein concentrates. These are products derived from milk where the primary constituents are proteins, and they have undergone a process to increase their protein concentration. This often involves removing lactose, minerals, and water. Examples include various forms of milk protein isolate (MPI) and milk protein concentrate (MPC) powders or liquids, intended for use in food manufacturing, nutritional supplements, or animal feed.

Within the broader heading of "Other: products consisting of natural milk constituents... not elsewhere specified or included," this particular subcategory is distinguished by its specific focus on concentrated milk proteins. While other products under 0404 might contain natural milk constituents, this classification isolates those where the protein fraction is the deliberately concentrated component.

As a leaf node, this classification does not have further subcategories. Therefore, the classification of a product under 0404.90.10.00 hinges on its nature as a concentrated milk protein product, not elsewhere classified within Chapter 4 or other HTS chapters. Importers and exporters should ensure that the product's composition and processing align with the definition of a milk protein concentrate, distinguishing it from less concentrated milk derivatives or other dairy-based products.
