4101.90.10.30 - Other

This HTS category, 4101.90.10.30, specifically covers "Other" raw hides and skins of bovine (including buffalo) or equine animals that have not undergone any tanning or further preparation. This includes pieces like butts, bends, and bellies, provided they remain in their pre-tanned state. The critical factor for classification here is the absence of any tanning process, which would move these materials to a different chapter within the HTS.

This classification distinguishes itself from its sibling category, "Fresh or wet-salted," by encompassing a broader range of preservation methods beyond simply being fresh or salted. While fresh or wet-salted hides are included, this "Other" category also accounts for hides that have been dried, limed, pickled, or otherwise preserved, as long as these treatments do not constitute tanning. The key is that these are still raw materials, not yet transformed into leather.

As this is a leaf node in the HTS classification, there are no further subcategories. Therefore, the focus for precise classification under 4101.90.10.30 rests on confirming that the material originates from bovine or equine animals, is not tanned or parchment-dressed, and falls under the "other" preservation methods not explicitly detailed in sibling categories. This ensures accurate duty assessment and trade facilitation for these raw materials.
