National Stock Numbers
The National Stock Number (NSN) is a 13-digit code used to identify each item in the FSC (NSN). FSC groups and classes are combined with a nine-digit national item identification number to form the NSN for a certain supply item (NIIN).
With the NIIN, each NSN item in the Federal Supply Distribution System has its own unique identification number, which is made up of a two-digit NCB code and an additional seven digits.
In the Department of Defense, the National Item Identification Identifier (NIIN) is a nine-digit number that identifies every supply item.
It is used to identify items inside a classification even though the NIIN is part of the NSN. The NIIN, in contrast to the FSC, is assigned in a random order, regardless of the item’s name, description, or categorization.
Criteria for Maintaining Stock on Hand in the Warehouse or Storeroom
Costs connected with holding inventory include not only the item’s initial purchase price but also the associated storage, counting, and rotational costs. Each item that is added to the inventory has to meet specific requirements in order to be included. In certain situations, a command may decide that an item must be on hand even though it is rarely needed; this is known as an exceptional case.
The demand for a product dictates how much of it should be kept in stock. Every time a customer asks for something, it’s considered a demand. If there are four requests per quarter, then the demand frequency is four. Recurring demands are distinguished from non-recurring demands. A recurring demand is one that is made for an item that is always in use. When there is a one-time, extremely big demand for a typically used item in smaller amounts, it’s referred to as a non-recurring demand. Generally, a warehouse item must meet three recurring demands in one quarter before it is stocked at the facility.
However, the quantity of requests is not the only factor to take into account. The cost and availability of the item are also taken into account (how long it takes to get it into the command).
An expensive item that can be ordered and supplied quickly is not a good option for the stock since it would be highly expensive to acquire enough to have on hand to meet the needs of the client. Consider the expiration date and shelf life as well.
Once the decision has been made to stock
the item, a determination must be made as to
how much of the item to keep and when to
reorder. Automated software programs will
calculate the stocking levels based upon the
projected monthly usage. A change to any of the
factors listed below will result in a change in the
overall projected inventory.
Levels of Supply
There will be control over the level or
quantity of supplies kept by departments.
Without controls, policy changes, or poor
ordering procedures may result in some items
being in short supply, while other items are
stockpiled in quantities that would not be
consumed for several years.
Supply Level Terminology
It is possible to express supply levels in two different ways: numerically or in terms of months of usage.
The total number of resources available is referred to as the numeric value. The most popular and effective way to account for the number of products utilized is to use “Months of Usage”.
All four stock item measures are employed to express the supply level, including the operational one as well as the safety one, storage one, and requisitioning one.
This measurement shows how much material is needed to keep operations running between replenishment shipments, which is usually seven days.
The level of operation should be determined by the replenishment cycle duration.
As the name implies, this measurement represents the amount of material necessary to keep operations running between replenishment shipments, which are typically sent every seven days.
Depending on how long the replenishing cycle lasts, the operating level should be adjusted accordingly
This metric shows how much of a given stock item is needed to keep things running well. In other words, it’s a combination of the operational and safety levels.
In order to support operations, the greatest amount of a stock item should be kept on hand and in stock.
Sum of operational and safety levels and quantity of an item consumed between the filing of demand and delivery of supplies (also known as stockage target).
There is a strong correlation between supply and demand.
Past experience, represented in accurate stock records, is the most reliable guidance when determining supply requirements. Material usage notes are aided by having updated stock record cards. It is possible to predict future usage rates using historical data. To keep track of all medical supplies on board, SAMS (SNAP Automated Medical System) is the currently approved shipboard computer program.
Re-Order Point (ROP)
This is the point at which replenishment is required. Replenishment is indicated if the stock on hand plus the due-in amount is less than the re-order point.
Order and Ship Time (OST)
When a stock replenishment action is started and received by the activity, the amount of time passes between them.
Orders placed under regular priority through a federal supply depot have an OST of 30 days; this time may be shortened if the material is procured from a local source or if transit is more expedient.
BUMED-Controlled Inventory Items
In order to preserve life (medications), BUMED-controlled inventory goods must be vital, highly pilferable (hemostats, etc.), and/or expensive to acquire or replace (CAT scan, XRay equipment). For typical BUMED-controlled items, the Navy uses NAVMED FORM 6700/13 ($100K – $249K) and NAVMED FORM 6700/12 ($250K). Send the request to the NAVMEDLOGCOM for review at the highest level of command.
Professional Books and Publications
NAVMEDCOMINST 5600.1, Procedures for Review of Naval Medical Command Publications, and NAVMEDCOMINST 6820.1, Professional Reference Materials and Publications, contain a list of all books and publications that must be kept on hand at any given time. GSA makes open-ended contracts for the acquisition of books on a regular basis. A credit card purchase is required under the terms of these contracts for all professional books and publications.
Requisitioning and Contracting Documents
In order to requisition and contract medical/dental supplies, certain documents are used. When working on the land or at sea, it is common to use documents such as the Defense Medical Logistics Standard Support (DMLSS) or SAMS. These documents can be printed out or prepared electronically.
DD Form 1348
Standard stock items with a National Stock Number can be ordered using this form (NSN). Military Standard Requisitioning and Issue Procedure (MILSTRIP) codes constitute the majority of the data required for a DD 1348.
DD Form 1348-6
This form is used to request non-NSN-identifiable material. For the most part, this type of report is more descriptive in nature and calls for information on supply sources, manufacturer’s code information, and relevant replacements. This form is used to requisition items from the Defense Supply Center Philadelphia (DSCP) Shared Procurement program.
DD Form 1149
shipping document containing a requisition and an invoice A requisition form and a shipment document both utilize this form. One or more line items of materiel can be requested using this form, which can be used locally. This is a form for ordering items available on the open market, and it allows you to provide a detailed description of the item’s source and technical specifications (s). To document purchase card transactions and ship materials between operations, it can also be employed. BUMED-controlled items, such as medical books and journals, as well as standard and nonstandard BUMED-controlled items needing local purchase action, can be procured under the GSA contract using this form.
DD Form 1155
Supply and Service Order — When placing an open market order with a seller, you must use this form as an official buy order document. This form is normally filled out by someone from the purchasing department and contains all of the order details.
