HS Code 3105.40 – Fertilizers, mineral or chemical; ammonium dihydrogenorthophosphate (monoammonium phosphate) and mixtures thereof with diammonium hydrogenorthophosphate (diammonium phosphate)
HS code 3105.40 is the 6-digit subheading for fertilizers, mineral or chemical, ammonium dihydrogenorthophosphate (monoammonium phosphate) and mixtures thereof with diammonium hydrogenorthophosphate (diammonium phosphate). It is used for monoammonium Phosphate (MAP) granular, MAP powder, water-soluble MAP, MAP-DAP blends and liquid MAP solutions.
What HS 3105.40 covers
This HS code covers ammonium dihydrogenorthophosphate, known as Monoammonium Phosphate (MAP), and mixtures of MAP with diammonium hydrogenorthophosphate (DAP). MAP is a crucial phosphatic fertilizer, offering a high concentration of phosphorus and a moderate amount of nitrogen. It is highly water-soluble, making it ideal for starter fertilizers, drip irrigation, and foliar applications, particularly in early growth stages to support root development and flowering. Global trade in MAP is substantial, driven by its versatility and effectiveness across diverse agricultural systems. Major producers include countries with significant phosphate rock reserves and ammonia production, such as China, the United States, and Morocco. Importers are widespread, with large agricultural economies like Brazil, India, and various European nations being key consumers. The trade dynamics are influenced by global crop demand and fertilizer market trends.

Codes often confused with 3105.40
Common mistake. Frequently confused with diammonium phosphate (DAP, 310530) due to their similar roles as phosphatic fertilizers; the key difference lies in their N:P ratio (MAP is typically 11-52-0, while DAP is 18-46-0).
Top exporters and importers of HS code 310540, 2025
In 2025, the largest exporter of HS code 310540 in UN Comtrade data was Morocco, with 37% of world exports; the largest importer in UN Comtrade data was Brazil, with 27% 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 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).
