1522.00.00.00 - Degras; residues resulting from the treatment of fatty substances or animal or vegetable waxes

This HTS category, 1522.00.00.00, encompasses "Degras; residues resulting from the treatment of fatty substances or animal or vegetable waxes." Degras, also known as wool grease or wool fat, are byproducts obtained from the scouring of sheep's wool. This heading also includes various residues generated during the processing of fats, oils, and waxes derived from either animal or vegetable sources. These residues are typically recovered during refining, rendering, or other manufacturing processes and may contain residual fatty acids, soaps, or other organic matter.

Unlike the preceding chapters within Section III which focus on primary fats, oils, and prepared edible fats, this category specifically addresses the secondary products and waste materials that arise from their treatment. While other headings in Chapter 15 might cover refined oils or waxes, 1522.00.00.00 is reserved for the materials that remain *after* the primary extraction or processing of these substances. This distinction is crucial for customs purposes, as these residues often have different commercial values and end uses compared to their parent fatty substances or waxes.

As this is a leaf node in the HTS database, there are no further subcategories. Therefore, classification under 1522.00.00.00 is determined by whether the imported material fits the definition of degras or a residue from the treatment of fatty substances or animal or vegetable waxes. Careful consideration should be given to the origin and processing of the material to ensure accurate classification, distinguishing it from commercially traded refined products.
