0403.90.47.00 - Described in general note 15 of the tariff schedule and entered pursuant to its provisions

This HTS category, 0403.90.47.00, specifically covers dried sour cream and buttermilk. For sour cream to fall under this classification, it must contain over 6 percent but not more than 35 percent by weight of butterfat. The "dried" designation indicates that the moisture content has been significantly reduced, typically through evaporation or spray-drying processes, resulting in a powdered or granular form. This category is distinct from other classifications within Chapter 4, particularly other forms of milk and cream products, by its specific combination of dairy type, fat content, and dried state.

The distinction between 0403.90.47.00 and its sibling categories at the same level is crucial for accurate classification. While 0403.90.51.00 covers certain other dairy products described in additional U.S. notes, this category focuses solely on dried sour cream and buttermilk meeting the specified butterfat criteria. Similarly, the "Other" sibling category (0403.90.55.00) encompasses dried fermented milk and cream products not meeting the precise definitions of sour cream or buttermilk as outlined here.

As 0403.90.47.00 is a leaf node within the HTS structure, it does not have further subcategories. Therefore, the primary focus for classification under this code rests on confirming that the product is indeed dried sour cream or buttermilk, adheres to the stipulated butterfat percentage range, and is not covered by any other specific provisions or notes that would direct it to a different classification. Examples of products that would fall here include dried sour cream powder used in baking mixes or as a flavoring agent, and powdered buttermilk used in various food preparations.
