The Supply Classification system is an indexing system used by Star Army Logistics to codify groups of materiel. It is wholly independent from other equipment labeling schemes, including manufacturer and IRN designations. Its purpose is to provide rough categorization for the purposes of coordinating safety and security measures in the storage and transport of supplies.
Note “I” is omitted from the classification scheme for its potential confusion with lower case L or the number one, depending on the font used for a particular display.
The classifications are primarily used in the Materiel Tracking System codes, identifying the broad category of supplies a given item belongs to. Additionally, the classes are used in rating the suitability of different storage and transportation mediums for specific types of cargo. Depending on the size, environmental factors, and security of various ships and installations they may or may not receive certification to handle certain classes of cargo.
Further, the classes can be used to issue priorities in emergency situations. For instance, a Fleet engaged in combat will receive priority for transport of Class A through E supplies, while the priority of Class K, L, and M supplies will be very low. Or, in a humanitarian crisis, transports carrying Class H and J supplies will be given priority transit and landing authorizations.
