HS Code for Tricalcium phosphate
Tricalcium phosphate is classified under HS code 2835.26. It falls within Chapter 28, which covers inorganic chemicals, specifically under Heading 2835 for phosphinates, phosphonates, and phosphates. While Heading 2835 covers various phosphates, subheading 2835.26 is designated for other phosphates of calcium, excluding dicalcium phosphate (calcium hydrogenorthophosphate), which has its own specific code. Tricalcium phosphate, often referred to as bone phosphate of lime or tribasic calcium phosphate, is a chemically defined compound used in food production, pharmaceuticals, and industrial applications. The classification is driven by the chemical composition and the degree of neutralization of the phosphoric acid. It must be a chemically defined compound to remain in Chapter 28; if it were a natural mineral, it would be classified in Chapter 25. The classification follows GRI 1 and 6, as the product is specifically described by the subheading text. This compound is widely used as an anti-caking agent in powdered foods and as a nutritional supplement, but its classification remains strictly based on its chemical identity as a calcium phosphate other than the dicalcium variety.
Products Included
- Pure tricalcium diphosphate
- Food-grade tricalcium phosphate (E341 iii)
- Tribasic calcium phosphate
- Precipitated calcium phosphate
- Bone ash (if consisting of chemically defined tricalcium phosphate)
Common Misclassification
Tricalcium phosphate is frequently confused with HS code 2835.25, which is specifically for calcium hydrogenorthophosphate (dicalcium phosphate). The two are chemically distinct based on the ratio of calcium to phosphate. Another common misclassification is HS code 2510, which covers natural calcium phosphates (apatite and phosphorite). If the product is a naturally occurring mineral that has not been chemically processed into a specific compound, it belongs in Chapter 25.
