Products classified under HTS 2835.26.00.00
Dicalcium Phosphate Dihydrate (DCPD)
Dicalcium phosphate dihydrate is a white, odorless powder composed of calcium hydrogen phosphate with two molecules of water, classified under HTS 2835.26.00.00 as other phosphates of calcium. It is primarily used as a dietary supplement in animal feed and as a phosphate source in food processing.
Tricalcium Phosphate (TCP) Powder
Tricalcium phosphate is a calcium orthophosphate powder used as a food additive, anticaking agent, and in pharmaceuticals, falling under HTS 2835.26.00.00 for other calcium phosphates. It provides calcium and phosphorus essential for bone health supplements.
Tetracalcium Phosphate (TTCP) for Biomedical Use
Tetracalcium phosphate is a high-calcium phosphate phase used in bone cements and dental restoratives, classified under HTS 2835.26.00.00 as other calcium phosphates. It reacts to form hydroxyapatite in vivo.
Hydroxyapatite Nanopowder (Synthetic Calcium Phosphate)
Synthetic hydroxyapatite nanopowder mimics bone mineral for coatings, scaffolds, and supplements, under HTS 2835.26.00.00 as other calcium phosphates. It is chemically defined as Ca10(PO4)6(OH)2.
Calcium Phosphate Tribasic Granules
