Direct exchange stockage items are repair parts considered to be
These are supplied from the SSA to using units
through a system known as DX. Under this procedure, unserviceable items are
exchanged for serviceable items on a one-for-one basis.
A list of items
authorized to be exchanged is provided to the using unit by the SSA. When
the using unit's parts clerk determines that the unserviceable item is DX,
he prepares DA Form 2402 (Exchange Tag). If the DX item is PLL, the parts
clerk will exchange the item, if available.
The DA Form 3318 is then
posted. The DX items that are not stocked or are at zero balance will be
assigned the appropriate Urgency of Need Designator (UND).
their designated representative must authenticate each high-priority DX item
by placing their signature in Block 8 of DA Form 2402. When the DX item is
turned in to the SSA, copy 1 of the DX tag is retained by the parts clerk as
a due-out, if a serviceable item is not on hand. Supervisors must ensure
that all unserviceable DX items are turned in promptly to the SSA for
exchange and that due-outs for DX items are on file in the unit's repair
Parts clerks should be required to make frequent contact
with their SSA to check on these due-outs.
Nonstocked Item Demand File. A separate file of DA Forms 3318 (Figure 31)
must be kept to record demands for nonstocked items.
These items may be
added to the PLL after meeting the stockage criteria of three demands in the
most recent 180 days (360 days for ARNG/USAR). The items may be added to
the PLL at the time of the third demand.
