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.
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.
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.
Demil A items will be released to the public whereas Demil D items will be sent for Demilitarization.
When creating a turn-in document for property with a Critical FSC, a clear text statement must be included detailing why the NSN is not included. Affirm if the FSC is on the Critical FSC list (4160.21) or the DML CD is missing on the 1348-1A.
