Calcium Phosphates (Other, NESOI)

Beyond dicalcium phosphate, the calcium phosphate family includes tricalcium phosphate, hydroxyapatite, and other specialty forms used in bone-graft biomaterials, ceramic coatings, and high-performance food additives — applications that command premium pricing and tighter purity specifications than commodity DCP. US imports are classified under 2835260000, a catch-all line that excludes calcium hydrogenorthophosphate. The Netherlands and Russia lead supply under this heading, with Japan and Morocco also notable sources. Food and pharmaceutical grades entering the US are subject to FDA admissibility review; importers should work with a licensed customs broker to confirm the correct classification and applicable agency requirements.
