HS Code for Dicalcium phosphate

Dicalcium phosphate, chemically known as calcium hydrogenorthophosphate, is classified under HS code 2835.25. Chapter 28 covers inorganic chemicals, and heading 2835 specifically includes phosphinates (hypophosphites), phosphonates (phosphites), and phosphates. Dicalcium phosphate is a phosphate of calcium. This classification applies to the chemical whether or not it is chemically defined. It is widely used as a dietary supplement in prepared animal feeds, as a tableting agent in pharmaceutical applications, and as a polishing agent in toothpaste. However, its classification in 2835.25 is based on its chemical identity as a distinct inorganic compound. The Harmonized System distinguishes between different calcium phosphates; while dicalcium phosphate is 2835.25, other phosphates like mono- or tricalcium phosphate may fall under 2835.26. The purity and intended use do not generally change the heading, provided the product remains a separate chemically defined compound.

Products Included

• Anhydrous dicalcium phosphate

Common Misclassification

Dicalcium phosphate is often misclassified under HS code 3103, which covers mineral or chemical phosphatic fertilizers. While it contains phosphorus, it is rarely used as a primary fertilizer in its pure form. Another common error is classification under 2309, which covers preparations of a kind used in animal feeding. While dicalcium phosphate is an ingredient in animal feed, the pure chemical remains in Chapter 28 unless it is mixed with other nutrients or additives to form a complete feed preparation.

FAQ

What is the HS code for Dicalcium phosphate?

The HS code for dicalcium phosphate (calcium hydrogenorthophosphate) is 2835.25.

Is feed-grade dicalcium phosphate classified differently?

Generally, no. Even if intended for animal feed, the pure chemical compound is classified under 2835.25 unless it has been mixed into a prepared feed supplement.
