HS Code 3105.59 – Fertilizers, mineral or chemical; containing the two fertilizing elements nitrogen and phosphorus, other than nitrates and phosphates

HS code 3105.59 is the 6-digit subheading for fertilizers, mineral or chemical, containing the two fertilizing elements nitrogen and phosphorus, other than nitrates and phosphates. It is used for urea ammonium phosphate, ammonium polyphosphate, NPK fertilizers (without potassium) where N is not nitrate, liquid N-P fertilizers and starter fertilizers.

What HS 3105.59 covers

This HS code covers mineral or chemical fertilizers containing the two fertilizing elements nitrogen and phosphorus, but specifically excludes those where nitrogen is exclusively in nitrate form and phosphorus is exclusively in phosphate form (covered by 310551). This 'other' category encompasses a broad range of N+P compounds, such as urea ammonium phosphate, ammonium polyphosphate, and various N-P blends where nitrogen might be in urea or ammonium form. These fertilizers are vital for balanced plant nutrition, supporting vegetative growth and root development. Global trade is extensive, with major agricultural economies both importing and exporting these diverse formulations. Key players include countries with robust fertilizer industries like China, the United States, and Russia, supplying markets in Brazil, India, and Southeast Asia. The specific chemical forms of N and P dictate their release rates and suitability for different soil conditions and crops.

Codes often confused with 3105.59

Common mistake. This 'other' category can be confused with specific N+P fertilizers like DAP (310530) or MAP (310540) if the exact chemical form isn't specified, or with NPK fertilizers (310520) if potassium is also present.

Top exporters and importers of HS code 310559, 2025

In 2025, the largest exporter of HS code 310559 in UN Comtrade data was China, with 36% of world exports; the largest importer in UN Comtrade data was Brazil, with 34% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
