required on a scheduled basis as prescribed in NAVSUP P-485.
CLASSIFIED ITEMS—Inventory classified items annually and upon each change of custodial responsibility.
HAZARDOUS ITEMS—Hazardous items are toxic, corrosive, oxidizing, flammable, radioactive, or other materials that pose a potential hazard to life or property. Inventory hazardous items identified in stock records by hazard item codes H, F, M, or R annually. It is also mandatory to inspect each unit of each item for its condition, correct identification, and proper labeling.
SECURITY ITEMS—You must inventory security-type medical supplies, such as narcotics, precious metals, alcohol, and alcoholic beverages (code R in the notes column of the Federal Supply Catalog C-65-IL sections). This also comprises inventorying those items identified in stock records by locally assigned management codes or appropriate notations monthly and upon each change of custodial responsibility. Other controlled medical items, such as barbiturates, antibiotics, and other drugs or substances coded “C,” are inventoried monthly.
OTHER MATERIEL—Other stock items that may be specifically designated by the inventory manager, fleet commander, TYCOM, or the commanding officer for special inventory control are inventoried according to the frequency criteria established by the directing authority.
SHELF-LIFE ITEMS—Deteriorative shelf-life items, other than those included in the items just discussed, do not require a periodic inventory. Screen these items often to ensure their timely use or transfer before the shelf-life expiration dates.
Spot Inventory
A spot inventory is an unscheduled physical inventory that is taken to verify the existence or nonexistence of a specific stock item. It is usually taken when the verified stock record for a requested item shows an on-hand balance, and the issue request indicates that the item is NIS. A spot inventory is also taken to determine the on-hand quantity of a particular item when it is requested by the commanding officer, a fleet commander, TYCOM, a cognizant inventory manager, or other competent authority. For example, the commanding officer may request the physical inventory of any item that he or she considers highly essential to prospective operations. Also, a fleet commander or TYCOM may need to have total asset visibility of a particular critical item or an inventory, disposition, and report of certain items that, after distribution within the supply system, are found to be defective.
Velocity Inventory
A velocity inventory is based on the premise that inaccuracies of stock record balances for any given items increase proportionately with issue frequency; therefore, concentrate most of the physical inventory effort on frequently demanded items. A velocity inventory requires a periodic physical count of all stock items that experience frequent demands (fast movers) and a physical count of items that experience infrequent or no demands (slow movers). Periodic inventories of SIM items and postissue inventories of non-SIM items are examples of velocity inventories.
SIM MATERIAL—Inventory SIM materiel in nonautomated ships semiannually, and complete the inventory within 2 weeks after commencement.
NON-SIM MATERIAL—Except for items designated as special materiel, or unless warranted under conditions previously discussed, do not take a complete inventory of non-SIM materiel. However, to provide sufficient stock record card accuracy for effective inventory control, inventory the balance of each item after each issue.
Random Sampling Inventory
The random sampling inventory is considered part of the annual scheduled inventory program. It is used only by authorized ships such as automated special accounting class 207 ships and automated aircraft carriers (except for aeronautical materiel). This inventory is a measure of the stock record accuracy for materiel based on the physical count of a specified number of randomly selected items within the segment. NAVSUP P-485 explains how to conduct a random sampling inventory.
