Ammonium nitrate (NH4NO3) is a white crystalline solid with a nitrogen content of approximately 34-35%, making it one of the most concentrated solid nitrogen fertilizers available. It contains both ammonium nitrogen (NH4+) and nitrate nitrogen (NO3-), providing both quick-acting and sustained nutrient release for crops. The nitrate form is immediately available for plant uptake, while the ammonium form is released gradually through soil microbial processes.
Beyond agriculture, ammonium nitrate is a key oxidizer used in mining and construction explosives (ANFO โ Ammonium Nitrate Fuel Oil). We supply both fertilizer-grade (dense prill) and porous prill grade (PPAN) for industrial explosive applications. All shipments comply with UN 1942 (Class 5.1) regulations and require appropriate import permits from destination countries.

Ammonium nitrate is a Class 5.1 oxidizer. Strong oxidizer that can intensify fires. Keep away from combustible materials, organic substances, reducing agents, fuels, oils, strong acids, and chlorides. Store in a dry, well-ventilated area away from heat sources and ignition points. Avoid contamination with incompatible materials. Decomposition at high temperatures can be explosive under confinement. Emergency responders should use large quantities of water โ do not use steam or dry chemicals.
Regulatory note: Many countries restrict or require special permits for ammonium nitrate import. Buyers must verify import regulations and obtain necessary permits before ordering.
Q: What is the difference between fertilizer-grade and porous prill grade (PPAN)?
Fertilizer-grade AN has dense prills (bulk density ~0.95 g/cm3) with low oil absorption, suitable for direct soil application. PPAN has porous prills (bulk density ~0.76-0.83 g/cm3) with high oil absorption (7%+), designed for ANFO explosive manufacturing.
Q: Which countries can you export to?
We can export to countries that allow ammonium nitrate import with proper documentation. Some countries (e.g., EU, Australia) have strict restrictions. We verify destination country regulations before accepting orders.
Q: What documents do you provide?
COA, MSDS, commercial invoice, packing list, bill of lading, and dangerous goods declaration. Certificate of Origin and other specific certificates available upon request.
