0507 - Ivory, tortoise-shell, whalebone and whalebone hair, horns, antlers, hooves, nails, claws and beaks, unworked or simply prepared but not cut to shape; powder and waste of these products:

Chapter 05 of the Harmonized Tariff Schedule (HTS) encompasses products of animal origin not elsewhere specified or included. Within this chapter, Heading 0507 specifically covers unworked or simply prepared raw materials derived from animal appendages and related organic substances. This includes natural ivory, tortoise-shell, whalebone and its hair, as well as horns, antlers, hooves, nails, claws, and beaks. The classification also extends to the powders and waste generated from these materials, provided they have not undergone significant shaping or manufacturing processes.

Heading 0507 is distinct from its sibling headings within Chapter 05, which cover other animal products such as live animals (Chapter 01), edible meat and fish (Chapters 02 and 16), dairy products (Chapter 04), animal fats and oils (Chapter 15), and prepared animal feed (Chapter 23). Unlike these, 0507 focuses solely on the raw, unprocessed, or minimally processed natural materials from specific animal body parts, emphasizing their origin and fundamental composition rather than their use as food or finished goods.

Heading 0507 is further subdivided to distinguish between ivory and other materials. Subheading 0507.10.00.00 is dedicated to ivory, encompassing both whole ivory tusks and any resulting powders or waste. The residual category, 0507.90.00, covers all other products fitting the description of Heading 0507, such as tortoise-shell, whalebone, horns, antlers, hooves, nails, claws, and beaks, along with their respective powders and waste, that are not classified under the ivory-specific subheading.
