Last updated: August 2026 dataAcid treatment of animal bones yields ossein — the collagen-rich precursor used in gelatin manufacturing — making this heading a critical upstream input for the food, pharmaceutical, and photographic industries. Brazil is the leading US supplier, with Ireland and Cambodia also among the top sources, reflecting both South American cattle-processing capacity and Asian processing hubs. Unlike raw bones, ossein and acid-treated bones are processed intermediates and do not typically trigger USDA FSIS meat inspection, but importers should confirm admissibility requirements with CBP and the relevant agency based on the specific processing state and intended use. Classification under the single US line (0506100000) is straightforward, but origin documentation is important given Brazil's prominence and the need to verify processing standards.

Ossein is the primary raw material for Type I collagen gelatin used in food products (confectionery, dairy), pharmaceutical capsules, and photographic film. Origin matters because processing standards — particularly regarding BSE (bovine spongiform encephalopathy) risk controls — vary by country. Brazil, the leading supplier, is recognized by USDA APHIS as a controlled-risk country for BSE, which affects the admissibility of certain bovine-derived materials; importers should verify current APHIS status before sourcing.
There are no widely applicable antidumping or countervailing duty orders on ossein from the major supplying countries as of recent schedules, and the heading carries a standard MFN duty rate. However, tariff treatment can change; importers should check the current HTS schedule and any applicable CBP rulings before entry, particularly when sourcing from countries subject to broader Section 301 or other trade-remedy actions.
