0404.10.11.00 - Described in additional U.S. note 10 to this chapter and entered pursuant to its provisions

This HTS classification covers modified whey that is not elsewhere specified or included and does not meet the criteria for classification under 0404.10.08.00. Modified whey, for the purposes of this heading, refers to whey that has undergone physical or chemical modification to alter its functional properties, such as solubility, emulsification, or viscosity. This can include processes like hydrolysis, ultrafiltration, or ion exchange, resulting in a product with specific applications in the food industry, such as in infant formulas, nutritional supplements, or processed cheese.

It is important to distinguish this category from its sibling, 0404.10.08.00, which is reserved for modified whey that is specifically described in general note 15 of the tariff schedule and entered pursuant to its provisions. This present classification, 0404.10.11.00, applies to all other modified whey products that do not fit the specific criteria of the sibling category. The key difference lies in the presence or absence of the specific descriptive provisions outlined in general note 15.

As this is a leaf node in the HTS classification system, there are no further subcategories to introduce. Therefore, the focus for classification under 0404.10.11.00 is on thoroughly understanding the nature of the "modified whey" and ensuring it is not eligible for any other more specific subheading, particularly the sibling category. Importers and customs brokers should carefully review the specific modification processes and intended uses of the whey product to ensure correct classification.
