Diammonium Phosphate (DAP) Supplier in Malaysia
- Also known as
- DAP
- Diammonium Hydrogen Phosphate
- Ammonium Phosphate Dibasic
- (NH4)2HPO4
Diammonium phosphate supplier for fertiliser, technical, food and industrial buyers in Malaysia. Also called DAP, diammonium hydrogen phosphate, ammonium phosphate dibasic or ammonium fosfat, it is the water-soluble salt (NH4)2HPO4 used mainly for nitrogen and phosphorus supply.
Fertiliser DAP is commonly referenced near 18-46-0. Technical and food grades use the same defined diammonium salt against different specifications. Monoammonium phosphate (MAP) is the monobasic salt and has its own page when NH4H2PO4 or a 12-61-0 requirement is specified.
Agriculture drives most demand: plantation programmes and NPK blends use DAP where its nutrient ratio suits the crop programme. Technical grades serve selected flame-retardant and process applications, while food grade supports specified buffering and yeast-nutrient uses.

Common questions about diammonium phosphate
What is diammonium phosphate (DAP)?
Diammonium phosphate is the dibasic ammonium phosphate salt (NH4)2HPO4, CAS 7783-28-0. It is traded as DAP, especially for fertiliser requirements, and is distinct from monoammonium phosphate (MAP).
How does DAP differ from monoammonium phosphate (MAP)?
Monoammonium phosphate is the monobasic salt NH4H2PO4 and is a different product with its own page. Order monoammonium phosphate by MAP, NH4H2PO4 or ammonium dihydrogen phosphate when that monobasic salt is required. This page covers the dibasic salt diammonium phosphate (DAP), (NH4)2HPO4.
What is diammonium phosphate (DAP) and the 18-46-0 ratio?
DAP is the dibasic salt (NH4)2HPO4, widely traded as a fertiliser grade of ammonium phosphate. The market nutrient ratio near 18-46-0 means roughly 18 percent nitrogen, 46 percent phosphate (P2O5) equivalent and no potash. It is a commercial reference rather than a guarantee for every lot, so confirm the required nutrient or assay values when requesting a quotation.
Which grade should I request?
Request DAP fertiliser grade for plantation blending and field programmes, technical grade for flame-retardant and industrial work, or food grade E342(ii) for buffering and yeast-nutrient use. State the application and any assay or impurity limits with the enquiry.
Can DAP be requested for flame-retardant formulations?
Yes. Technical diammonium phosphate is used in selected flame-retardant formulations. Send purity, particle-size and formulation targets so the quoted grade matches the use.
What details are needed for an ammonium phosphate price enquiry?
Provide the grade, application, target specification or nutrient ratio, quantity and delivery location. Mention packing preferences and any documents needed so availability, packing and commercial terms can be confirmed with the quotation.
