0507.90.00 - Other

Category 0507.90.00, described as "Other," encompasses a range of products derived from animal parts that are not specifically classified under other headings within Chapter 5. This includes materials such as whalebone, whalebone hair, horns, antlers, hooves, nails, claws, and beaks. Importantly, these products must be in an unworked state or only simply prepared, meaning they have not been significantly altered or shaped beyond initial processing. Powder and waste derived from these specified animal materials also fall within this category.

This "Other" category serves as a residual classification for items not detailed in the sibling category, 0507.10.00.00, which exclusively covers ivory, along with its powder and waste. Therefore, if a product consists of horn, hoof, or claw that is unworked or simply prepared, it would be classified here, distinct from any item made of ivory. The distinction lies in the specific biological origin of the material.

Within category 0507.90.00, further subdivisions exist to provide more granular classification. Subcategory 0507.90.00.10 specifically addresses "Velvet antler," which refers to the soft, furry covering on growing antlers before they harden. All other remaining products fitting the general description of "Other" under 0507.90.00, and not classified as velvet antler, are consolidated under the residual subcategory 0507.90.00.90. This hierarchical structure ensures precise identification of various unworked or simply prepared animal-derived materials within the tariff schedule.
