Monoammonium Phosphate for Water-Soluble Fertilizer Blends
If you blend a water-soluble fertilizer with MAP, specify nutrient declarations and dissolution as well as compound assay.
Relia's monoammonium-phosphate candidates can be reviewed for nitrogen, phosphorus basis, insoluble matter and physical form.

Manufacturing Support for This Purchase
Relia manufactures monoammonium phosphate materials in China through its own factories.
Our MAP enquiry should identify whether you need a water-soluble crystalline material or another physical fertilizer form. Give us the declared nutrient basis, solubility requirements and relevant destination specifications. The proposed NH4H2PO4 grade and the complete blend are separate acceptance records, even where the purchasing programme includes both.

The Nutrient Requirement
The MAP listings describe ammonium dihydrogen phosphate white crystals with at least 98% assay. That does not establish a finished N-P-K declaration or irrigation-grade suitability. We first request a clear nutrient and impurity record for the actual offered grade, then compare it with your fertilizer-manufacturing requirements.

MAP Assay and Fertilizer Nutrient Data Are Different Fields
| Review area | Listed data and acceptance basis | Use in your selection |
|---|---|---|
| MAP · 6288 | The title states 98% minimum water-soluble material for fertilizer trials. Confirm identity and a separate nutrient analysis. | Identify exactly what the percentage measures before normalising quotations or dosage. |
| Industrial MAP · 6344 | A white-crystal entry at 98% minimum. Industrial wording does not establish the requirements of every fertilizer system. | Use your required finished-product result as the acceptance point for the candidate. |
| Industrial MAP · 6343 | Another 98%-designated entry. Agree actual nitrogen/phosphate reporting bases and relevant impurities. | Use your required finished-product result as the acceptance point for the candidate. |
| Formulation brief | State fertilizer route, water and dissolution needs, relevant insolubles and the nutrient declaration you need to substantiate. | Identify exactly what the percentage measures before normalising quotations or dosage. |

Solubility in Your Blend
Compare the identified material within the intended fertilizer formulation or dissolution evaluation. Record relevant nutrient analysis, insolubles and compatibility results. We do not turn a 98% chemical assay into a declared N-P-K grade or claim suitability for every irrigation system.

Assay only
Does not establish the nutrient grade.
Reporting basis
Must be stated clearly.
Market needs
Require actual supporting documents.
Reaction, Purification and Soluble-Crystal Finishing
Ammonium phosphate manufacture begins with controlled reaction chemistry; a crystalline soluble product then needs appropriate solution purification and crystallisation, while granular fertilizer uses another finishing route. These physical forms should not share an assumed specification. Connect the offered nutrient analysis and insoluble-matter result with the actual dissolution and blending requirements.
Define the phosphate product
MAP identity and the intended crystalline or granular physical form must be clear.
Form the ammonium phosphate
Controlled reaction chemistry creates the phosphate solution or intermediate.
Prepare soluble crystals
For crystalline soluble material, purification, crystallisation and separation address a different product task from granular finishing.
Retain nutrient and use data
Connect the offered nutrient basis and insoluble matter with actual dissolution and blending requirements.
- Nutrient basis
- MAP assay is not the N–P2O5–K2O declaration.
- Solubility
- Retain the method and relevant insoluble-matter limit.
- Form
- Do not transfer a granular fertilizer specification to a crystalline soluble product.
A Market-Specific Purchase File
Retain the nutrient and trial records with the proposed grade and batch. We discuss the actual documents required for your destination. A general industrial or fertilizer use label is not a substitute for that review.

Connect the Next Purchasing Step
If your fertilizer blend has a chloride limit, choose potassium sulfate using an explicit chloride result and nutrient basis.
If you buy urea for fertilizer blending, match the particle form to your blend and handling system.
If a promising sample needs to become a repeat purchase, make the approval record as clear as the trial result.
