1505.00.90.00 - Other

This HTS category, 1505.00.90.00, covers "Other" fatty substances derived from wool grease. It encompasses lanolin and other materials that are the product of wool grease processing but do not fall under the more specific classification of crude wool grease. These may include purified lanolin, lanolin derivatives, or other processed forms intended for various industrial, cosmetic, or pharmaceutical applications.

Distinguishing this category from its sibling, 1505.00.10.00 (Wool grease, crude), is crucial. Crude wool grease is the raw, unrefined material obtained directly from the wool. The "Other" category, however, applies to substances that have undergone further processing, purification, or chemical modification beyond the initial extraction. This refinement typically alters the physical characteristics, purity, and intended uses of the material.

As this is a leaf node, there are no further subcategories. Therefore, classification within 1505.00.90.00 relies on determining that the goods are indeed derived from wool grease, are not crude wool grease, and are not specifically provided for elsewhere. Practical classification will often involve examining product specifications, certificates of analysis, and information regarding the processing steps undertaken to arrive at the final product.
