Local Stock Numbers

When using a Local Stock Number (LSN) in place of a National Stock Number (NSN) it is critical to choose the correct LSN from the LSN Master List.

LSNs have assigned Demil Codes which DLA Disposition Services will use to determine their final disposition.

Research Tools

Most items already have an established NSN that should be selected if at all possible. Various research tools are available to determine NSNs based on nomenclature, physical identifiers, part numbers or other available attributes of property needing disposal.

• WebFLIS provides essential information about supply items including the National Stock Number (NSN), Item Name, Reference/Part Numbers, Commercial and Government Entity (CAGE) codes and other Federal logistics data.
  This information will be primarily used by DLA, military services, and United States (U.S.) Government sponsored contractors doing business with the U.S. Government.
• H2 FSC Directory The H2 FSC Directory defines Federal Supply Groups (FSG) and Federal Supply Classifications (FSCs) and cross references them.
• H2 FSC Handbook a hard copy handbook that details the information and requirements for FSCs and relevant information.
• H6 Item Name Directory The H6 Item Name DIrectory defines Item Names and cross references them to Item Name Codes (INC) and Federal Supply Classes (FSC). You may search the H6 by keyword, FSC, Federal Item Identification Guide (FIIG) or INC.

If you are unable to determine an NSN, and choose to use an LSN, please keep the following guidelines in mind.

Commercial off the shelf items need to use a Demil A LSN, items with any military application (that can contain any inherent offensive or defensive capabilities) need to use a Demil D LSN.

Critical FSCs

Property that belongs to a Critical Federal Supply Class that is turned in under an LSN requires additional information. Due to national security concerns, the FSCs listed in DOD 4160.21-M, chapter 3, attachment 2, require a higher degree of documentation.

When these items are not assigned an NSN, the DTID must include:

• the appropriate FSC 
• valid part number
• manufacturer’s name
• nomenclature that accurately describes the item
• the end item application, and
• a clear text statement explaining why the NSN is not included.

Customers must affirm if the FSC is on the Critical FSC list (DOD 4160.21-M, chapter 3, attachment 2) or the DEMIL code is missing on the 1348-1A. This information may be annotated directly on the DTID or securely attached to the DTID.
