Classification of nitrogen fertilizer under HS 3102.90
The classification of nitrogenous fertilizers under HS code 3102.90 is determined by the chemical composition of the product and its specific exclusion from other more specific subheadings within heading 3102. Heading 3102 is dedicated to mineral or chemical fertilizers that provide nitrogen, a primary nutrient for plant growth. Subheading 3102.90 serves as a residual category for products that do not meet the specific criteria of the preceding subheadings, such as urea (3102.10), ammonium sulfate (3102.21), or mixtures of ammonium nitrate with calcium carbonate (3102.40). This classification is strictly guided by General Interpretative Rule (GIR) 1, which prioritizes the terms of the headings and any relative Section or Chapter Notes. Chapter 31 Note 2 defines the substances that fall under heading 3102. For a product to be classified here, it must be a mineral or chemical nitrogenous fertilizer, whether or not pure, or a mixture of such products. The \"other\" designation in 3102.90 is crucial for innovative fertilizer blends or less common nitrogenous compounds that are not explicitly listed elsewhere. It is important to note that if the fertilizer contains other primary nutrients like phosphorus or potassium in significant quantities, it may be moved to heading 3105. The classification also considers the physical form, such as tablets or similar forms, or in packages of a gross weight not exceeding 10 kg, which might shift the classification to 3105.10.

Codes often confused with 3102.90
Common mistake. A frequent error is classifying these products under 3102.10 (Urea) if the product contains urea but is actually a mixture. Another common mistake is using 3105.20 (NPK fertilizers) when the product only contains nitrogen but is mistakenly thought to be a complex fertilizer. Additionally, if the nitrogenous fertilizer is packaged for retail sale in small quantities (under 10kg), it must be classified under 3105.10 regardless of its chemical composition.
Top exporters and importers of HS 310290 (the code used for nitrogen fertilizer), 2025
In 2025, the largest exporter of HS 310290 (the code used for nitrogen fertilizer) in UN Comtrade data was Poland, with 11% of world exports; the largest importer in UN Comtrade data was Brazil, with 14% of world imports. Russia did not report 2025 data, and its estimate from partner records misses its trade with other countries that did not report: in 2024 that was 54% of its exports here ($50M, CEPII BACI), so it may also belong among the top exporters.
Figures cover everything classified under HS 310290, not only nitrogen fertilizer.

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).
