3504.00.10.00 - Protein isolates

This HTS category, 3504.00.10.00, specifically covers "protein isolates." Protein isolates are highly purified protein products derived from various sources, such as soy, whey, or pea. They are characterized by a protein content typically exceeding 90% on a dry basis, with a significant reduction in non-protein components like fats and carbohydrates. These isolates are often produced through advanced extraction and purification processes to achieve their concentrated protein form.

Within Chapter 35, protein isolates are distinguished from their sibling category, 3504.00.50.00, which encompasses "other" protein substances and their derivatives not elsewhere specified. While both fall under the broader heading of "peptones and their derivatives; other protein substances and their derivatives," the 3504.00.10.00 designation is for highly refined and concentrated protein products, whereas the "other" category would include less purified protein fractions or derivatives with different functional properties.

As this is a leaf node in the HTS classification system, there are no further subcategories under 3504.00.10.00. Therefore, the primary focus for classification under this code is to confirm that the imported product meets the definition of a protein isolate, meaning it is a purified protein substance derived through processes designed to isolate and concentrate protein content to a high degree.
