Product classification
HS code for UAN fertilizer: 3102.80
Fertilizers, mineral or chemical, nitrogenous, mixtures of urea and ammonium nitrate in aqueous or ammoniacal solution.
Classification of UAN fertilizer under HS 3102.80
UAN (Urea Ammonium Nitrate) fertilizer is classified under HS code 3102.80. This classification is governed by Chapter 31 of the Harmonized System, which covers fertilizers. Heading 3102 is dedicated to nitrogenous mineral or chemical fertilizers. Subheading 3102.80 specifically addresses mixtures of urea and ammonium nitrate in aqueous or ammoniacal solution. This product is a liquid fertilizer typically containing between 28% and 32% nitrogen. The classification is precise because the product is a chemical mixture of two nitrogen sources (urea and ammonium nitrate) stabilized in water. Because it is a specific chemical mixture defined by the HS nomenclature, it takes precedence over more general nitrogenous fertilizer codes.

Codes often confused with 3102.80
Common mistake. UAN is often misclassified under HS code 3102.10 (pure urea) or HS code 3102.30 (pure ammonium nitrate). However, because UAN is a mixture of both, those codes are incorrect. It is also sometimes confused with HS code 3105, which is for fertilizers containing two or three of the fertilizing elements nitrogen, phosphorus, and potassium. Since UAN only contains nitrogen, it must remain in 3102.
Top exporters and importers of HS 310280 (the code used for UAN fertilizer), 2025
In 2025, the largest exporter of HS 310280 (the code used for UAN fertilizer) 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).
