1505.00.10.00 - Wool grease, crude

This HTS classification covers crude wool grease, also known as wool fat or lanolin in its raw, unprocessed form. Wool grease is a natural substance secreted by the sebaceous glands of sheep and other wool-bearing animals. It is a complex mixture of fatty acids, alcohols, and esters, primarily used for its emollient and moisturizing properties in various industries. Examples include the raw output directly from wool scouring processes before further refinement or purification.

The distinction between 1505.00.10.00 and its sibling category, 1505.00.90.00 (Other), lies in the degree of processing. This classification specifically targets the crude, unrefined state of wool grease. The "Other" category would encompass any lanolin or fatty substances derived from wool that have undergone further processing, such as purification, degreasing, or chemical modification, rendering them distinct from the raw material.

As this is a leaf node, there are no further subcategories within this specific HTS code. Classification under 1505.00.10.00 is determined by the product being wool grease in its initial, unadulterated form, as collected and before any significant refining or treatment has been applied.
