Bone Powder, Waste, and Horn-Core Products

The US schedule separates crude, steamed, or ground bones (0506900020) from powder and waste of bones and horn-cores (0506900040). The key distinction is the degree of size reduction and processing: whole or coarsely ground bones fall under the former, while finely milled powder and processing residues fall under the latter. Accurate classification requires knowing the particle size and processing method of the specific product.

USDA APHIS maintains country-specific restrictions on animal-origin products, including bones and bone meal, based on the disease status of the exporting country — particularly regarding BSE (bovine spongiform encephalopathy). Importers must verify current APHIS admissibility conditions for the specific country of origin before shipment.
