HS Code for DCP

Dicalcium phosphate (DCP), chemically known as calcium hydrogenorthophosphate, is classified under HS code 2835.25. This classification is governed by the structure of Chapter 28, which covers inorganic chemicals. Heading 2835 specifically includes phosphinates (hypophosphites), phosphonates (phosphites), and phosphates. Within this heading, the nomenclature provides a specific subheading for calcium hydrogenorthophosphate. To qualify for this code, the product must be a chemically defined compound, although the HS allows for certain impurities. The classification remains consistent whether the DCP is intended for use as a food additive, a laboratory reagent, or a component in industrial processes. However, the physical state and the presence of additives intended to make it suitable for specific uses, such as animal feed, can sometimes complicate the classification process, requiring a strict adherence to Chapter 28 Note 1 regarding the definition of separate chemically defined compounds.

Products Included

• Anhydrous dicalcium phosphate
• Dicalcium phosphate dihydrate
• Food-grade calcium hydrogenorthophosphate
• Reagent-grade dicalcium phosphate

Common Misclassification

DCP is often misclassified under 2309.90 if it is prepared as an animal feed supplement with added vitamins or other nutrients. It may also be confused with 3103.11 or 3103.19 if it is presented as a mineral fertilizer (superphosphates). If the product is a mixture of different phosphates not elsewhere specified, it might be incorrectly placed in 3824.99. Pure calcium phosphates other than the hydrogenorthophosphate are classified under 2835.26.

FAQ

What is the HS code for DCP?

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

Is feed-grade DCP classified differently?

Pure dicalcium phosphate used in feed is still 2835.25, but if it is mixed with other ingredients to form a complete feed supplement, it moves to 2309.90.
