1517.90.45.00 - Described in general note 15 of the tariff schedule and entered pursuant to its provisions

This HTS classification, 1517.90.45.00, specifically covers margarine, edible mixtures, or preparations of animal, vegetable, or microbial fats or oils, or fractions thereof, that are *not* classified under heading 1516 and fall under the specific criteria of General Note 15. These products are essentially edible fat-based preparations designed for culinary use, with their classification determined by specific provisions outlined in the tariff schedule's general notes.

Within the "Other" subcategory of edible mixtures, 1517.90.45.00 distinguishes itself from its sibling categories by its explicit reference to General Note 15 for its classification criteria. This differentiates it from 1517.90.50.00, which relies on Additional U.S. Note 10 to chapter 4, and 1517.90.60.00, which represents a residual "other" category for products not meeting the specific conditions of the preceding subheadings. Therefore, proper classification under 1517.90.45.00 hinges on adherence to the detailed requirements stipulated within General Note 15.

As this is a leaf node, there are no further subcategories. The classification is finalized at this level, indicating that the goods meeting the description and provisions of General Note 15 are definitively classified here. Examples within this category could include specific types of margarines or prepared edible fat blends that, while fitting the general scope of heading 1517, are precisely defined by the parameters of General Note 15.
