Joint Hazard Classification System (JHCS)

The Joint Hazard Classification System (JHCS) is the official DOD database of final hazard classification data for the military services' ammunition and explosives. It is maintained by USATCES and is updated on a frequent basis. Explosive items are evaluated and tri-service coordinated between hazard classifiers for the Army, Navy, and Air Force following procedures in TB 700-2/NAVSEAINST 8020.8B/TO 11A-1-47/DLAR 8220.1, Department of Defense Ammunition and Explosives Hazard Classification System. The DDESB, proponent for the bulletin, publishes changes to hazard classification procedures. Approved items are added to the JHCS database after assignment of an EX number by the Department of Transportation (DOT) and are published for use by authorized customers on a need-to-know basis.

An interim hazard classification (IHC) is a mechanism used by DOD to allow for the transportation of Class 1 material in the U.S. when the item's final hazard classification process has not been completed. It is a memorandum, signed by authorized personnel within the Army, Navy, and Air Force, describing the item and giving it a temporary hazard classification. The IHC governing regulation is TB 700-2/NAVSEAINST 8020.8B/TO 11A-1-47/DLAR 8220.1, chapter 7, which is empowered by 49 Code of Federal Regulation (CFR), Section 173.56(b)(2)(i).
