HS Code for Ground phosphates

Ground phosphates are classified under HS code 251020. This code falls within Chapter 25, which covers salt, sulfur, earths and stone, plastering materials, lime, and cement. Heading 2510 specifically includes natural calcium phosphates, natural aluminium calcium phosphates, and phosphatic chalk. The classification is divided between unground (251010) and ground (251020) materials. To be classified under 251020, the phosphate must be a natural mineral product that has been mechanically ground. It must not have been chemically treated or processed into a finished fertilizer, as chemical modification would shift the classification to Chapter 31. This code is primarily used for raw materials in the chemical and fertilizer industries.

Products Included

• Ground natural calcium phosphate
• Ground phosphatic chalk
• Ground natural aluminium calcium phosphate
• Apatite in ground form

Common Misclassification

Ground phosphates are frequently misclassified under HS code 251010, which is for unground natural phosphates. A more critical error is classifying these minerals under heading 3103 (mineral or chemical phosphatic fertilizers). Heading 3103 is only appropriate if the phosphates have been chemically treated (e.g., with sulfuric acid to create superphosphates). If the product is a mixture of ground phosphates and other fertilizing elements like nitrogen or potassium, it must be classified under heading 3105.

FAQ

What is the HS code for Ground phosphates?

The HS code for ground natural calcium phosphates and related minerals is 251020.

Does this code include synthetic phosphates?

No, HS code 251020 is strictly for natural phosphates. Synthetic or chemically produced phosphates are classified in Chapter 28 (chemicals) or Chapter 31 (fertilizers).
