Phosphate fertilizers
MAP — Monoammonium Phosphate
NH₄H₂PO₄ — 12-52-0
The densest phosphate available in a granular fertilizer at 52 percent P₂O₅, with a modest nitrogen contribution alongside it. Applied at establishment, where phosphate availability determines early root development.
MAP is mildly acidic in the immediate zone around the granule, which keeps phosphate available on calcareous soils where DAP's alkaline reaction can lock it up. On neutral and acid soils the difference is small and the choice becomes a price and analysis question.

Classification, HS code and transport regime are confirmed per grade and per route at the offer stage. Figures below are indicative of the standard specification.
Packaging
- Bulk, in covered equipment or weather-tight holds
- Big bag 500 / 1000 / 1250 kg
- PP bags 25 and 50 kg, palletised and hooded
Storage and handling
- Dry, covered storage; moderately hygroscopic
- Segregate from alkalis and from urea in prolonged contact
- Granulometry preserved by limiting transfer points — every handling produces fines
Transport
- Unregulated for transport by road, rail and sea
- Covered equipment; clean holds with previous cargo history checked
Documents
- Technical data sheet (TDS) — issued with the offer
- Safety data sheet (SDS) in the languages of transit and destination
- Certificate of analysis, lot-specific, drawn at loading
- Certificate of origin and EUR.1 where the destination allows preference
Documents are issued against a confirmed enquiry rather than published for download — an SDS is only meaningful for the grade and revision actually shipped.
