HS Code for Monoammonium phosphate
Monoammonium phosphate (MAP), chemically known as ammonium dihydrogenorthophosphate, is classified under HS code 3105.40. This heading covers mineral or chemical fertilizers containing two or three of the fertilizing elements nitrogen, phosphorus, and potassium. MAP is a widely used source of both phosphorus and nitrogen. The classification 3105.40 specifically includes MAP and mixtures thereof with diammonium hydrogenorthophosphate (DAP). The Harmonized System distinguishes between pure chemicals and those intended for use as fertilizers. While pure ammonium dihydrogenorthophosphate could technically be classified in Chapter 28 (Inorganic Chemicals), Note 2 to Chapter 31 specifies that certain products, including MAP, are to be classified in heading 3105 even if they are not used as fertilizers, provided they are in the forms described. This ensures a uniform classification for this specific chemical compound regardless of its end-use purity, provided it meets the criteria of the heading. MAP is highly valued in agriculture for its high nutrient content and its ability to dissolve quickly in soil, making it an efficient delivery system for essential plant nutrients. The classification is vital for applying the correct agricultural tariffs and monitoring the trade of essential farming inputs.

Common Misclassification
MAP is often confused with Diammonium phosphate (DAP), which is classified under 3105.30. While similar, they have different chemical structures and nitrogen-to-phosphorus ratios. Another misclassification is 2835.22, which covers mono- or disodium phosphates; however, ammonium phosphates are specifically directed to Chapter 31 by legal notes.
