This classification covers dried, fermented or acidified milk and cream products that are not specifically listed under preceding subheadings within heading 0403.90. Specifically, this subheading pertains to sour cream and buttermilk, in dried form, which contain no more than 6 percent by weight of butterfat. The "Other" designation at this level signifies that these products do not meet the specific criteria for other subcategories within dried fermented milk and cream.

Distinguishing this category from its siblings, 0403.90.37.00 covers products described in general note 15, and 0403.90.41 pertains to items meeting the criteria of additional U.S. note 12. This particular subheading, 0403.90.45.00, is for dried sour cream and buttermilk with a butterfat content not exceeding 6 percent, and which do not fall under those specialized general or additional U.S. note provisions.

As this is a leaf node, there are no further subcategories. Classification within this subheading is determined by the physical form (dried), the nature of the fermented product (sour cream or buttermilk), and the precise butterfat content, ensuring accurate distinction from other fermented milk and cream products within the tariff schedule.
