HS Code 2835.24 – Phosphates; of potassium, whether or not chemically defined
HS code 2835.24 is the 6-digit subheading for phosphates, of potassium, whether or not chemically defined. It is used for monopotassium phosphate (MKP), dipotassium phosphate (DKP), tripotassium phosphate (TKP), potassium dihydrogen phosphate and potassium hydrogen phosphate.
What HS 2835.24 covers
This HS code covers potassium phosphates, including monopotassium phosphate, dipotassium phosphate, and tripotassium phosphate. These compounds are highly valued for their dual applications in agriculture and the food industry. In farming, they serve as crucial fertilizers, delivering essential phosphorus and potassium for optimal plant growth. In the food sector, they function as effective emulsifiers, thickeners, and buffering agents, commonly found in dairy products, processed meats, and beverages. They are also utilized in water treatment and as chemical reagents. Agricultural suppliers, food manufacturers, and chemical distributors are key importers, with large chemical and fertilizer companies being the main exporters. Trade in potassium phosphates requires careful attention to purity, specific grade (food-grade vs. technical-grade), and strict compliance with agricultural and food safety regulations. Their integral role in both food production and processing ensures a consistent and significant global demand.

Codes often confused with 2835.24
Common mistake. Potassium phosphates (2835.24) are distinct from sodium phosphates (2835.22) and calcium phosphates (2835.25) due to the specific cation, which impacts their properties and applications.
Top exporters and importers of HS code 283524, 2025
In 2025, the largest exporter of HS code 283524 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).
