HS code for Nitrate phosphate fertilizer: 3105.51

Fertilizers, mineral or chemical, containing nitrates and phosphates.

Classification of nitrate phosphate fertilizer under HS 3105.51

Nitrate phosphate fertilizer is classified under HS code 3105.51. This classification is found within Chapter 31, which is dedicated to fertilizers. Heading 31.05 covers mineral or chemical fertilizers containing two or three of the fertilizing elements nitrogen, phosphorus, and potassium; other fertilizers; and goods of this chapter in tablets or similar forms or in packages of a gross weight not exceeding 10 kg. Subheading 3105.51 specifically addresses those fertilizers that contain both nitrates and phosphates. These are binary fertilizers (NP) that provide two primary nutrients. The classification is determined by the chemical composition of the mixture. This code includes mixtures of ammonium nitrate with calcium phosphates or other phosphate-bearing minerals intended for soil enrichment. The Harmonized System notes for Chapter 31 specify that heading 31.05 includes only fertilizers of a kind used as such and containing, as essential constituents, at least one of the fertilizing elements. For 3105.51, the presence of both nitrogen (in nitrate form) and phosphorus (in phosphate form) is the defining characteristic. This classification is critical for trade statistics and the application of agricultural tariffs and subsidies.

Codes often confused with 3105.51

Common mistake. Nitrate phosphate fertilizer is often misclassified under 3102.30, which is for ammonium nitrate alone. However, if phosphates are added, it must move to 3105. Another common error is using 3105.20, which is for NPK fertilizers. If the mixture contains any amount of potassium, 3105.20 takes precedence over 3105.51. Additionally, pure ammonium phosphate without nitrates would be classified under 3105.40.

Top exporters and importers of HS 310551 (the code used for nitrate phosphate fertilizer), 2025

In 2025, the largest exporter of HS 310551 (the code used for nitrate phosphate fertilizer) in UN Comtrade data was Russia, with about 24% of world exports; the largest importer in UN Comtrade data was Canada, with 13% of world imports. Peru 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 99% of its imports here ($73M, CEPII BACI), so it may also belong among the top importers.

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).
