AMMONIUM NITRATE- ▸ Fertilizer: high-nitrogen fertilizer input
- ▸ Explosives: oxidizer in industrial and mining blasting agents (ANFO)
- ▸ Cold packs: endothermic dissolution in instant cold packs
- ▸ Chemical intermediate: feedstock including nitrous oxide production
A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.

Transport classification per the UN Model Regulations / 49 CFR 172.101 Hazardous Materials Table. Confirm against the grade-specific SDS (Section 14) before shipping.
Ammonium nitrate (CAS 6484-52-2), technical grade. Industry references record its dominant uses as a high-nitrogen fertilizer and as an oxidizer in industrial and mining explosives, with additional use in instant cold packs (endothermic dissolution) and as a chemical intermediate.
Frequently Asked Questions
What is technical grade ammonium nitrate used for?
Technical-grade ammonium nitrate is used as a high-nitrogen fertilizer input, as the oxidizer in industrial and mining blasting agents (ANFO), in instant cold packs via endothermic dissolution, and as a chemical intermediate including nitrous oxide production. Industry references record fertilizer and oxidizer use as its dominant applications. Supply and end use are subject to applicable purchaser and security requirements.
What is the difference between technical grade and fertilizer grade ammonium nitrate?
Technical-grade ammonium nitrate is manufactured to specifications suited for industrial and oxidizer applications, while fertilizer-grade (e.g., 34-0-0 prilled) is formulated and coated for agricultural nitrogen delivery. Both share CAS 6484-52-2 and the NH4NO3 chemistry but differ in particle form, additives, and purity. Confirm the grade against your application on the Certificate of Analysis.
What happens if ammonium nitrate gets wet?
Ammonium nitrate is hygroscopic and dissolves readily in water; moisture causes caking, prilling breakdown, and loss of free flow, which is why it is stored dry and often coated against moisture pickup. Wet or recrystallized material can also bridge in storage. Follow the SDS and product storage guidance for handling and warehousing.
What is the chemical formula and CAS number of ammonium nitrate?
Ammonium nitrate is NH4NO3 (CAS 6484-52-2), classified under HS code 3102.30. It is supplied as a technical-grade solid. Identity and assay are confirmed on the CoA.
How is technical-grade ammonium nitrate packaged and shipped?
It is supplied in bags, supersacks, and bulk to qualified industrial purchasers and ships under UN 1942 (ammonium nitrate). Transport requires the corresponding DOT/IMDG documentation and packaging, and purchases are subject to applicable security and end-use verification. Request a bulk quote with SDS and CoA.
