1501.20.00.40 - Choice white grease

This classification, HTS Code 1501.20.00.40, specifically covers "choice white grease." Choice white grease is a high-quality, rendered fat derived from pigs. It is characterized by its light color, neutral odor, and clean taste, making it suitable for a range of industrial applications, particularly in the food industry as a component in certain food products or as a processing aid.

This category is distinguished from its sibling entries by its specific quality and appearance. "Yellow grease" (1501.20.00.60), the other sibling, is a lower-grade rendered animal fat, typically darker in color and with a stronger odor, often used for non-food industrial purposes such as the production of animal feed or biofuels. "Other" (1501.20.00.80) would encompass any other pig fat falling under the broader category of "Other pig fat" that does not meet the specific criteria of choice white grease or yellow grease.

As a leaf node, HTS Code 1501.20.00.40 has no further subcategories. Therefore, the focus for classification purposes within this code is on confirming the physical and chemical characteristics that define "choice white grease," ensuring it meets the stringent requirements for color, odor, and purity to be distinguished from other grades of pig fat.
