Fertilizers, mineral or chemical, nitrogenous, other kinds including mixtures not specified in the foregoing subheadings.
Classification of mixed nitrogen fertilizer under HS 3102.90
Mixed nitrogen fertilizer is classified under HS code 310290. This classification is governed by the legal notes to Chapter 31, which covers mineral or chemical fertilizers. Heading 3102 specifically addresses nitrogenous fertilizers. While specific subheadings exist for pure substances like urea (310210), ammonium sulfate (310221), and ammonium nitrate (310230), the subheading 310290 is reserved for "other" nitrogenous fertilizers, including mixtures of different nitrogenous fertilizing substances that do not meet the criteria for the more specific subheadings. According to Note 2 to Chapter 31, heading 3102 applies only to products used as fertilizers and containing nitrogen as the essential constituent. If the mixture contains other primary fertilizing elements like phosphorus or potassium in significant quantities, the classification would shift to heading 3105. However, for products where nitrogen is the sole fertilizing element provided by a blend of different nitrogen-bearing chemicals, 310290 is the correct designation. This ensures that complex chemical blends intended for soil enrichment are accurately documented for international trade and environmental regulation.

Codes often confused with 3102.90
Common mistake. A frequent misclassification occurs with HS code 310520, which covers mineral or chemical fertilizers containing the three fertilizing elements: nitrogen, phosphorus, and potassium. If a nitrogenous mixture contains even small intentional amounts of phosphorus or potassium, it must be moved to Chapter 3105. Additionally, 310210 (Urea) is often used incorrectly for mixtures where urea is the main component but other nitrogenous salts are present; if it is a mixture, 310290 is generally more appropriate unless the mixture is specifically described by another subheading.
Top exporters and importers of HS 310290 (the code used for mixed nitrogen fertilizer), 2025
In 2025, the largest exporter of HS 310290 (the code used for mixed 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.

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).
