Product classification
HS code for Urea fertilizer: 3102.10
Fertilizers, mineral or chemical, nitrogenous, urea, whether or not in aqueous solution.
Classification of urea fertilizer under HS 3102.10
Urea fertilizer is classified under HS code 310210 because it is a nitrogenous mineral or chemical fertilizer. According to the General Rules of Interpretation (GRI) and the Chapter 31 notes of the Harmonized System, urea is specifically identified by its chemical composition as a diamide of carbonic acid. When intended for use as a fertilizer, whether or not it is in an aqueous solution, it falls under this specific subheading. The classification is determined by the product's primary function as a soil nutrient provider and its high nitrogen content, typically around 46%. Even if the urea is of technical grade, if it is not put up in specific forms or packings as described in heading 3105, it remains under 310210. The purity of the product does not generally move it out of Chapter 31 unless it is specifically prepared as a reagent or for non-agricultural chemical synthesis in a way that meets other chapter definitions.

Codes often confused with 3102.10
Common mistake. Urea fertilizer is frequently confused with HS code 390910, which covers urea resins and amino-resins in primary forms. While both contain urea, 390910 is for plastic polymers and adhesives. Another common error is using HS code 3105, which is reserved for fertilizers containing two or three of the fertilizing elements (nitrogen, phosphorus, and potassium). If urea is mixed with phosphates or potash, it must be moved to 3105. Additionally, pure urea used as a laboratory reagent might sometimes be incorrectly filed under Chapter 29 (Organic Chemicals), but the HS nomenclature specifically directs most urea to 3102.
Top exporters and importers of HS 310210 (the code used for urea fertilizer), 2025
In 2025, the largest exporter of HS 310210 (the code used for urea fertilizer) 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 urea fertilizer.

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).

Questions about urea fertilizer
What is the HS code for Urea fertilizer?
The HS code for Urea fertilizer is 310210 (Fertilizers, mineral or chemical; nitrogenous, urea, whether or not in aqueous solution). The primary HS code for urea fertilizer is 310210, which covers mineral or chemical nitrogenous fertilizers.
How do I classify Urea fertilizer for customs?
Urea fertilizer is classified under HS code 310210 — Fertilizers, mineral or chemical; nitrogenous, urea, whether or not in aqueous solution. This is a 6-digit subheading level code.
Is liquid urea classified differently than solid urea?
No, HS code 310210 specifically includes urea whether or not it is in an aqueous solution, meaning both liquid and solid forms share the same code.
Which countries are the top exporters of urea fertilizer (HS 310210)?
In 2025, the top exporters of HS 310210 (the code used for urea fertilizer) in UN Comtrade data were Russia (about $3.8B, 16% of world exports), Nigeria ($2.2B) and Qatar (about $2.1B). World exports came to about $24.5B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of urea fertilizer (HS 310210)?

World imports came to about $26.5B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Is the HS code for Urea fertilizer the same in all countries?
The base HS code 310210 for Urea fertilizer is internationally standardized for the first 6 digits across 200+ countries. Individual countries may add additional digits for national tariff lines and specific classifications.
What is the NCM code for urea fertilizer in Brazil?
Brazil splits HS 310210 into 2 NCM codes, so the right one for urea fertilizer depends on the product's details: 3102.10.10 (Urea, over 45% nitrogen (dry basis)), 3102.10.90 (Other urea, not over 45% nitrogen (dry basis)).
