Last updated: April 2026 dataAmmonium nitrate — whether in solid prilled or granular form or dissolved in aqueous solution — is classified under 3102300000 and is one of the most tightly regulated nitrogen fertilizers in US commerce due to its explosive potential. The Department of Homeland Security, EPA, and ATF all impose facility registration, storage, and reporting requirements on importers and distributors, layered on top of standard CBP entry procedures. Canada is the leading supplier, followed by Russia and the Netherlands. Russian-origin ammonium nitrate warrants close monitoring for applicable trade-remedy or sanctions-related restrictions.

Beyond US Customs and Border Protection, importers must comply with EPA Risk Management Program requirements, DHS Chemical Facility Anti-Terrorism Standards (CFATS) registration for facilities above threshold quantities, and ATF regulations if the product meets explosive precursor definitions. State-level fire codes add another layer of compliance.
No. HTS 3102300000 explicitly covers ammonium nitrate 'whether or not in aqueous solution,' so both solid and liquid forms are classified identically. However, the physical form affects packaging, transport, and hazmat documentation requirements under DOT regulations.
