Product classification
HS code for Mineral nitrogen fertilizer: 3102.29
Fertilizers, mineral or chemical, nitrogenous, other than ammonium sulphate.
Classification of mineral nitrogen fertilizer under HS 3102.29
Mineral nitrogen fertilizer is classified under HS code 3102.29. This classification is governed by Chapter 31 of the Harmonized System, which is dedicated to fertilizers. Heading 31.02 specifically covers mineral or chemical fertilizers that are nitrogenous in nature. The subheading 3102.29 is a residual category for nitrogenous fertilizers other than those explicitly listed in the preceding subheadings (such as urea, ammonium sulphate, or ammonium nitrate). This code typically includes double salts and mixtures of ammonium sulfate and ammonium nitrate, or other mineral nitrogenous compounds that do not meet the specific criteria for the more common nitrogen fertilizers. To qualify for this code, the product must be a mineral or chemical product used primarily for its nitrogen content to promote plant growth.
- Covers
- Double salts of ammonium sulfate and ammonium nitrate
- Calcium cyanamide containing more than 25% nitrogen
- Mixtures of ammonium chloride and ammonium sulfate
- Other mineral nitrogenous fertilizers not specified in 3102.10 through 3102.21
- Also under 3102.29
- YaraBela CAN
- Nutrien UAN
- SQM Sodium Nitrate
- Haifa CalciN
- Tessenderlo Thio-Sul
Codes often confused with 3102.29
Common mistake. The most frequent misclassification occurs when a fertilizer contains more than one fertilizing element. If the nitrogen fertilizer is mixed with phosphorus or potassium, it must be classified under heading 31.05 (e.g., NPK fertilizers) rather than 31.02. Additionally, pure ammonium sulphate is classified under 3102.21, and urea is classified under 3102.10. Importers must ensure the chemical composition is strictly nitrogenous and does not fit into the more specific subheadings of 31.02 before using 3102.29.
Top exporters and importers of HS 310229 (the code used for mineral nitrogen fertilizer), 2025
In 2025, the largest exporter of HS 310229 (the code used for mineral nitrogen fertilizer) in UN Comtrade data was Slovakia, with 24% of world exports; the largest importer in UN Comtrade data was Germany, with 33% of world imports.

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).
