Monocalcium Phosphate (MCP)
Feed Grade
- Chemical formula
- Ca(H₂PO₄)₂·H₂O
- CAS No.
- 10031-30-8
- HS Code
- 2835.26
- Appearance
- White to light-grey powder
The most concentrated, fastest-dissolving and most readily absorbed feed phosphate, allowing a lower inclusion rate in the ration and freeing space for other ingredients. Ideal for poultry, fish and shrimp feeds where high phosphorus bioavailability is required.

* Available phosphorus: the fraction of phosphorus the animal can actually digest and utilise, determined in the laboratory by its solubility in 2% citric acid. The product is partially water-soluble and is intended for inclusion in dry feeds; it is not intended for dissolving in drinking water.
Applications
- High-performance poultry feeds
- Fish and shrimp feeds
- Livestock and ruminant feeds
- Premixes and feed concentrates
Packaging & Storage
- Lined polypropylene bags of 25 / 50 kg or 1-tonne jumbo bags
- Hygroscopic: keep sealed in a cool, dry place
- Shelf life: 24 months in the original sealed packaging
Notes for buyers
What is the phosphorus percentage of MCP?
Pure monocalcium phosphate monohydrate (Ca(H₂PO₄)₂·H₂O, molar mass ≈ 252.1 g/mol) contains 24.6% P and 15.9% Ca, calculated from the IUPAC standard atomic weights. Feed-grade MCP is specified on its guaranteed minimum: this sheet guarantees total P ≥ 22.0%, available P ≥ 20.9% (soluble in 2% citric acid) and water-soluble P ≥ 80% of P; the certificate of analysis gives the actual result for each batch.
How much MCP replaces DCP?
From the guaranteed minimums: 1 / 0.209 ≈ 4.8 kg MCP per kg of available P (1 / 0.22 ≈ 4.5 kg on total P), against ≈ 6.2 kg DCP. So about 4.8 kg MCP does the work of 6.2 kg DCP; the calcium difference is made up with limestone, and the final formulation is the nutritionist’s decision.
Safety: Mildly acidic material that may cause eye irritation. Wear goggles, gloves and a dust mask during handling; in case of eye contact rinse with plenty of water. A Safety Data Sheet (SDS) and a Certificate of Analysis (COA) for every batch are available on request.
