Product classification
HS code for DAP fertilizer: 3105.30
Fertilizers, mineral or chemical, diammonium hydrogenorthophosphate (diammonium phosphate).
Classification of DAP fertilizer under HS 3105.30
DAP fertilizer, or diammonium hydrogenorthophosphate, is classified under HS code 310530. This classification is governed by the General Rules of Interpretation (GRI) 1 and 6, which prioritize the specific chemical identity of the product. Within Chapter 31, which covers fertilizers, heading 3105 is reserved for mineral or chemical fertilizers containing two or three of the fertilizing elements nitrogen, phosphorus, and potassium. Since DAP is a compound containing both nitrogen (in the form of ammonium) and phosphorus (as phosphate), it is explicitly named in subheading 310530. The classification remains consistent regardless of whether the product is intended for direct soil application or as a component in complex fertilizer blends, provided it remains a separate chemically defined compound as described in the Harmonized System Explanatory Notes.

Codes often confused with 3105.30
Common mistake. DAP is frequently confused with Monoammonium Phosphate (MAP), which falls under HS code 310540. While both are ammonium phosphates, MAP contains only one ammonium group. Additionally, it may be misclassified under 3102 (nitrogenous fertilizers) or 3103 (phosphatic fertilizers) if the dual-nutrient nature is overlooked. Some importers mistakenly use 283539 for polyphosphates, but 310530 is the specific code for the fertilizer-grade diammonium salt.

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).
