MCP and DCP are feed mineral sources, but commercial products can differ in phosphorus, calcium, moisture, particle size and impurity profile. Buyers should compare an agreed specification, not abbreviations alone.
Identity and nutrient profile
Monocalcium phosphate and dicalcium phosphate contain different proportions of calcium and phosphorus. Commercial feed-grade material may also differ by hydration state and manufacturing route. Confirm the declared chemical form and guaranteed nutrient levels for the actual product.
What matters during supplier qualification?
Guaranteed analysis
Specify minimum phosphorus and calcium, maximum moisture and any other nutrient limits used by your formulation and incoming-control teams.
Contaminants and feed safety
Set limits for fluorine, arsenic, lead, cadmium and other relevant contaminants in line with destination-market rules and your risk assessment. Request the current specification and a representative or batch COA.
Physical quality
Particle-size distribution, powder or granular form, caking tendency and flow can influence blending, segregation and handling. State these requirements in the RFQ.
Documents and market status
Confirm the SDS, specification, COA format, manufacturer or site information, feed registration status where applicable, and certificates required by the destination. Feed-grade status is source-specific and should not be inferred from the name MCP or DCP.
RFQ checklist
- Product form and guaranteed phosphorus/calcium
- Maximum fluorine and heavy-metal limits
- Particle size and packing
- Target species or feed category for regulatory review
- Destination country, quantity and shipment window
