HS Code 3105.51 – Fertilizers, mineral or chemical; containing nitrates and phosphates
HS code 3105.51 is the 6-digit subheading for fertilizers, mineral or chemical, containing nitrates and phosphates. It is used for ammonium nitrate phosphate, calcium nitrate phosphate, NPK fertilizers with nitrate-N and phosphate-P, nitrophosphate fertilizers and water-soluble nitrate-phosphate blends.
What HS 3105.51 covers
This HS code specifically covers mineral or chemical fertilizers containing both nitrates and phosphates. These specialized fertilizers provide nitrogen in the readily available nitrate form, alongside phosphorus, making them highly effective for rapid nutrient uptake and targeted applications, especially in high-value crops or during specific growth phases. The combination ensures quick plant response and efficient nutrient delivery. Trade in these products is often driven by demand from regions with intensive agriculture, greenhouse operations, and horticulture, where precise nutrient management is critical. Exporters typically include advanced chemical manufacturers in Europe and North America, while importers are found globally, particularly in countries focusing on high-yield or specialty crop production. The specific balance of nitrate and phosphate is a key factor in their application and market value.

Codes often confused with 3105.51
Common mistake. Can be confused with other N+P fertilizers (310559) if the specific nitrate form of nitrogen isn't clearly identified, or with NPK fertilizers (310520) if potassium is also present in significant amounts.
Top exporters and importers of HS code 310551, 2025
In 2025, the largest exporter of HS code 310551 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).

What are common misclassifications for HS code 310551?
Can be confused with other N+P fertilizers (310559) if the specific nitrate form of nitrogen isn't clearly identified, or with NPK fertilizers (310520) if potassium is also present in significant amounts.
Which countries are the top exporters of goods under HS code 310551?
In 2025, the top exporters of HS code 310551 in UN Comtrade data were Russia (about $85M, 24% of world exports), the United States ($69M) and Bulgaria ($55M). World exports came to about $351M, 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 goods under HS code 310551?
In 2025, the top importers of HS code 310551 in UN Comtrade data were Canada ($68M, 13% of world imports), Germany ($54M) and Ukraine (about $51M). World imports came to about $507M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). 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 is HS code 310551 structured?
HS code 310551 is a 6-digit subheading under the Harmonized System. The first 2 digits (31) identify the chapter, digits 3-4 (05) identify the heading, and digits 5-6 (51) specify the subheading. This code is standardized globally by the World Customs Organization.
What is the Brazil NCM code for HS code 310551?
