1503.00.00.00 - Lard stearin, lard oil, oleostearin, oleo-oil and tallow oil, not emulsified or mixed or otherwise prepared

This HTS classification, 1503.00.00.00, specifically covers certain rendered animal fats and oils that have not undergone further processing beyond their initial separation. This includes lard stearin and lard oil, derived from pork fat; oleostearin and oleo-oil, which are derived from beef or mutton fat; and tallow oil, also a product of rendered animal fat. Crucially, these products are classified here only if they remain in their basic, unadulterated state, meaning they are not emulsified, mixed with other substances, or otherwise prepared for specific uses, such as for consumption or industrial applications.

The distinction from sibling categories lies in the *type of product and its state of preparation*. While other categories within Chapter 15 might cover live animals (Chapter 01), or different forms of fats and oils (e.g., vegetable oils, processed animal fats), this node is precise in its definition of specific animal-derived fats and oils in their raw, unmixed form. It focuses on the foundational components of these rendered fats, distinguishing them from more complex preparations or products derived from different sources.

As this is a leaf node within the HTS structure, there are no further subcategories. The classification is therefore final for products meeting the description. Any emulsification, mixing, or preparation beyond the initial rendering and separation would necessitate reclassification under a more specific heading or subheading, likely within Chapter 15 but at a more detailed level indicating the subsequent processing or intended use of the fat or oil.
