HS code for Dipotassium phosphate: 2835.24

Phosphates, of potassium, whether or not chemically defined.

Classification of dipotassium phosphate under HS 2835.24

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.

Codes often confused with 2835.24

Common mistake. 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.

Top exporters and importers of HS 283524 (the code used for dipotassium phosphate), 2025

In 2025, the largest exporter of HS 283524 (the code used for dipotassium phosphate) in UN Comtrade data was China, with 49% of world exports; the largest importer in UN Comtrade data was Mexico, with 10% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
