Product classification
HS code for Urea ammonium nitrate solution: 3102.80
Fertilizers, mineral or chemical, nitrogenous, mixtures of urea and ammonium nitrate in aqueous or ammoniacal solution.
Classification of urea ammonium nitrate solution under HS 3102.80
Urea ammonium nitrate (UAN) solution is classified under HS code 3102.80. This code is found in Chapter 31, which is dedicated to fertilizers. Heading 3102 covers mineral or chemical fertilizers that are nitrogenous. Subheading 3102.80 specifically identifies mixtures of urea and ammonium nitrate in aqueous or ammoniacal solution. The classification is based on the chemical composition and the physical state of the product. UAN is a liquid fertilizer widely used in agriculture because it combines three forms of nitrogen: nitrate, ammonium, and urea. To fall under this specific code, the product must be a solution; solid mixtures of these components would be classified elsewhere. The Harmonized System distinguishes between pure substances and mixtures, and 3102.80 is the precise designation for this specific liquid nitrogenous blend. This ensures that agricultural trade statistics, environmental regulations, and specific fertilizer tariffs are accurately applied by customs authorities worldwide.

Codes often confused with 3102.80
Common mistake. UAN solution is often misclassified as pure urea (3102.10) or pure ammonium nitrate (3102.30). It can also be confused with 3105.20 if it contains phosphorus or potassium. If the mixture is in a solid form rather than a solution, it may fall under 3102.90 as another nitrogenous fertilizer mixture.
Top exporters and importers of HS 310280 (the code used for urea ammonium nitrate solution), 2025
In 2025, the largest exporter of HS 310280 (the code used for urea ammonium nitrate solution) in UN Comtrade data was Russia, with about 28% of world exports; the largest importer in UN Comtrade data was the United States, with 31% 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 marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
