HS code for Nitrogen fertilizer (urea): 3102.10

Fertilizers, mineral or chemical, nitrogenous, urea, whether or not in aqueous solution.

Classification of nitrogen fertilizer (urea) under HS 3102.10

Urea is classified under HS code 3102.10. As the most widely used nitrogen fertilizer globally, urea is specifically identified in the first subheading of heading 3102. This code covers urea whether it is in a solid state (such as prills or granules) or in an aqueous solution. Chapter 31, Note 2(A)(viii) explicitly includes urea, whether or not pure, in heading 3102. This is a significant rule because it ensures that urea is classified as a fertilizer even if it meets high chemical purity standards that might otherwise suggest classification in Chapter 29 (Organic Chemicals). The classification is based on the chemical's primary use in global trade as a concentrated nitrogen source. Accurate classification under 3102.10 is vital for applying the correct agricultural tariffs and for monitoring the supply chain of this essential commodity.

Codes often confused with 3102.10

Common mistake. Urea (3102.10) is frequently misclassified with 3102.80 when it is part of a Urea Ammonium Nitrate (UAN) solution. If the solution is a mixture of urea and ammonium nitrate, 3102.80 is the correct code, whereas 3102.10 is for urea alone. Another error is using 2924.19, which covers acyclic amides and their derivatives; however, the legal notes to Chapter 31 specifically pull urea into the fertilizer category. Furthermore, if urea is packaged in small units (e.g., under 10kg) for retail sale, it may be classified under 3105.10 regardless of its chemical composition.

Top exporters and importers of HS 310210 (the code used for nitrogen fertilizer (urea)), 2025

In 2025, the largest exporter of HS 310210 (the code used for nitrogen fertilizer (urea)) in UN Comtrade data was Russia, with about 16% of world exports; the largest importer in UN Comtrade data was India, with 18% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

Figures cover everything classified under HS 310210, not only nitrogen fertilizer (urea).

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).
