  distribution, and movement and retrograde of repairable items to maintenance support activities.
  Additionally, multinational and interagency partners, HNs, and nongovernmental and other organizations

  critical to the overall success of joint operations. For more information see JP 4-0.
  CLASSES OF SUPPLY
  A-8. There are ten classes of supply in the Army supply system. The following list describes each class of
  supply:
  • Class I consists of bottled or packaged water, perishable, and semi-perishable subsistence items or
  rations that are packaged as individual or group meals. The individual Soldier meals in the family
  of rations consist of Meals Ready to Eat, First Strike Ration or Close Combat Assault Ration, Meal
  Cold Weather, and Modular Operational Ration Enhancement. Bottled or packaged water is potable
  water packaged for single use and intended for direct individual consumption. It has its own National
  Stock Number control by DLA and ordered through the supply chain. Generally, bottled water is
  only used in contingency operations, civilian humanitarian relief, or theater opening when bulk
  potable water is not yet fully available to meet the requirements. Bulk water consists of military
  service or contracted production, storage, and distribution that meet potable use requirements.
  • Class II consists of common consumable items such as clothing, individual equipment, tentage, tool
  sets and kits, maps, and administrative and housekeeping supplies. This includes items of
  equipment, other than major end items, prescribed in authorization/allowance tables and items of
  supply (not including repair parts). Small batteries for handheld devices are also included in this
  group.
  • Class III includes both bulk and packaged petroleum products. Bulk petroleum products are those
  petroleum products (fuels, lubricants) which are normally transported by pipeline, rail tank car, tank
  truck, barge, or tanker and stored in tanks or containers having a capacity of more than 55 gallons,
  except fuels in 500-gallon collapsible containers, which are packaged. Packaged petroleum products
  are those petroleum products other than fuels (generally lubricants, greases, and specialty items)
  that are stored, transported, and issued in containers with a capacity of 55 gallons or less.
  • Class IV consists of fortification, barrier, and construction materials.
  • Class V consists of ammunition of all types, bombs, explosives, mines, fuses, detonators,
  pyrotechnics, missiles, rockets, propellants, and other associated items.
  • Class VI consists of personal demand items (such as health and hygiene products, soaps, and
  toothpaste, writing materials, snack food, and beverages) and other items, including mail, that are
  non-military sales items.
  • Class VII consists of major end items such as weapon systems and vehicles. Major end items are a
  final combination of end products that are ready to use.
  • Class VIII consists of medical materiel and supplies to include medical device repair parts, blood,
  and blood products.
  • Class IX consists of any repair part, subassembly, assembly, or component required in the
  maintenance or repair of an end item, subassembly, or component. They support the maintenance
  and repair functions performed throughout the theater on all materiel except medical. Large batteries
  for vehicles, to include hybridization and charging stations for energy sources, are also included in
  Class IX.
  • Class X consists of items that support nonmilitary programs such as agricultural and economic
  development.
