Plain-language overview

Use HS-6 283525 when importing or exporting dicalcium phosphate, a common ingredient in animal feed and fertilizers. For example, if you are shipping a 25 kg bag of dicalcium phosphate for livestock nutrition, this is the correct code.

This code specifically covers calcium hydrogenorthophosphate, which is often used in dietary supplements and food fortification. It differs from HS-6 283526, which pertains to calcium phosphate in a more general sense, including other forms like tricalcium phosphate.

Dicalcium phosphate is recognized for its nutritional benefits, particularly in enhancing calcium and phosphorus levels in animal diets. It’s important to distinguish it from other phosphates, such as ammonium phosphates, which fall under different HS codes.

When considering shipments, ensure your product is accurately labeled as dicalcium phosphate to avoid classification issues. Misclassification can lead to delays or additional duties.
