HS Code for Dipotassium phosphate

Dipotassium phosphate is classified under HS code 2835.24. Chapter 28 covers inorganic chemicals, including precious metal compounds and isotopes. Heading 2835 is designated for phosphinates (hypophosphites), phosphonates (phosphites), and phosphates, as well as polyphosphates. Within this heading, the subheadings are organized by the cation associated with the phosphate. Subheading 2835.24 specifically covers phosphates of potassium. Dipotassium phosphate (K2HPO4) is a water-soluble salt often used as a fertilizer, food additive, and buffering agent. For customs purposes, as long as it is a separate chemically defined element or compound, it stays in Chapter 28. If it were mixed with other fertilizing elements like nitrogen or phosphorus in a specific ratio for retail sale as a fertilizer, it would be classified in Chapter 31. The classification follows GRI 1, as the chemical identity of the product aligns perfectly with the text of subheading 2835.24.

Products Included

• Dipotassium hydrogen orthophosphate
• Dibasic potassium phosphate
• Anhydrous dipotassium phosphate
• Food-grade dipotassium phosphate

Common Misclassification

It is often confused with 2835.22 (mono- or disodium phosphates) or 2835.29 (other phosphates). It may also be misclassified under 3105.60 if it is imported as a mineral or chemical fertilizer containing the two fertilizing elements phosphorus and potassium, though pure dipotassium phosphate usually remains in 2835.
