Analysis
HTS 0506.10.00 covers ossein and bones treated with acid under heading 0506 (bones and horn-cores, unworked, defatted, simply prepared (but not cut to shape), treated…).
The normal trade relations rate here is zero, shared by about 75% of the 20 tariff lines in chapter 05, a useful check when a neighbouring dutiable line is a candidate. Chapter 99 measures such as Section 301 or 232 can still apply on top, depending on where the goods come from.
The other line in the same group is 0506.90.00 (bones and horn-cores, unworked, defatted, simply prepared…, duty-free).
Census statistics map these goods to NAICS 311611 (Animal (except Poultry) Slaughtering), an industry of 1,274 US establishments employing 159,965 people. That concordance is how imports of this line are compared with US output.
Every edition we compared, from Jan 2023 to Oct 2026 (Rev. 22), shows the same general rate of Free.
