HS Code 3105.30 – Fertilizers, mineral or chemical; diammonium hydrogenorthophosphate (diammonium phosphate)
HS code 3105.30 is the 6-digit subheading for fertilizers, mineral or chemical, diammonium hydrogenorthophosphate (diammonium phosphate). It is used for diammonium Phosphate (DAP) granular, DAP powder, bulk DAP fertilizer, blended DAP products and liquid DAP solutions.
What HS 3105.30 covers
This HS code specifically identifies diammonium hydrogenorthophosphate, commonly known as Diammonium Phosphate (DAP). DAP is a highly concentrated and widely used phosphatic fertilizer, valued for its high phosphorus content and significant nitrogen contribution. It's a global commodity, essential for promoting strong root development and early plant vigor, making it a popular choice for pre-plant or at-planting applications across a vast array of crops. Major producers include countries with access to phosphate rock and ammonia, such as China, India, the United States, and Morocco, which export to agricultural regions worldwide. Key importers are typically large farming economies like Brazil, India, and Southeast Asian nations, where demand for efficient phosphorus sources is consistently high. The trade in DAP is influenced by global grain prices, energy costs, and environmental regulations.

Codes often confused with 3105.30
Common mistake. Can be confused with monoammonium phosphate (MAP, 310540) due to similar chemical composition and use; however, DAP has a higher nitrogen content relative to phosphorus (typically 18-46-0 vs. 11-52-0 for MAP).

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).
