CFATS Announcement

As of July 28, 2023, Congress has allowed the statutory authority for the Chemical Facility Anti-Terrorism Standards (CFATS) program (6 CFR Part 27) to expire.

Therefore, CISA cannot enforce compliance with the CFATS regulations at this time. This means that CISA will not require facilities to report their chemicals of interest or submit any information in CSAT, perform inspections, or provide CFATS compliance assistance, amongst other activities. CISA can no longer require facilities to implement their CFATS Site Security Plan or CFATS Alternative Security Program.

CISA encourages facilities to maintain security measures. CISA’s voluntary ChemLock resources are available on the ChemLock webpages.

If CFATS is reauthorized, CISA will follow up with facilities in the future. To reach us, please contact

This flyer is a resource to ensure facilities are aware that ammonium nitrate—Chemical Abstracts Service Number (CAS #) 6484-52-2—is a chemical of interest (COI) under the Chemical Facility Anti-Terrorism Standards (CFATS) regulation. Review the flyer below or Appendix A to learn more about when ammonium nitrate must be reported to the Cybersecurity and Infrastructure Security Agency (CISA).

Please download, print, and distribute this flyer as a resource to increase awareness of the CFATS program.
