(a) Fine PM (troy ounces) available for issue: gold, silver, and the platinum 

family metals.

(b) Issues (troy ounces) of gold, silver, and the platinum family metals.

(c) Issue price of gold, silver, and the platinum family metals.

3. DISPOSAL PROCESSING 

a. DoD generating activities and other participating FCAs are required to transfer all excess 

fine PM and PM-bearing materiel to their servicing DLA Disposition Services site. However, 

there may be times when a generating activity may be authorized to ship PM-bearing materiel,

such as electrolytic flake, film ash, or electronics, directly to a commercial contractor. In 

addition to specific PM-bearing property that requires special handling as a part of the turn-in 

process found in Volume 4 of this manual, sources of PM-bearing items eligible for processing 

for PM recovery can be found at Table 7.

b. NSN items that contain potentially recoverable PM are so coded in the FLIS and federal 

logistics under the PMIC. PM-bearing electronic scrap will be segregated and sorted (if 

necessary) into the appropriate SCL code on the DLA Disposition Services Website: 

www.dispositionservices.dla.mil. From this page, click on “CAT Book”; items are listed 

alphabetically under the Standard Waste and Scrap Classification List. PM-bearing scrap 

sources listed in Table 7 may contain any of the PM, either solely or in combination.

c. The generating activities (the DoD, FCA, etc.) will:

(1) Transfer excess usable PM-bearing property, scrap, and waste material to DLA 

Disposition Services sites IAW uniform transfer procedures contained in Enclosure 4 of Volume 

1 of this manual.

(2) Include on the DTID or attached documentation, any available information pertaining 

to the PM content, such as metal type, quantity, location, PMIC, and any known or suspected 

hazardous components.

(3) Properly segregate PM-bearing scrap and waste material before transferring to a 

DLA Disposition Services site.

d. The DLA Disposition Services sites will:

(1) Comply with guidance set forth within Reference (q), as it applies to receipt and 

documentation of materiel coming into DLA Disposition Services sites, including PM-bearing 

materiel.

(2) Accept accountability for PM-bearing materiel, except where acceptance is prevented 

by law or regulation (some examples are ammunition and explosives (AE) unless certified inert, 

Classified unless declassified). When appropriate storage or security facilities are not available, 

DLA Disposition Services sites will arrange for generating activities or the host installation to 

retain or accept custody of the materiel until such time as disposition can be accomplished.

(3) Make every effort to confirm the presence of PM when materiel is received that has 

not been identified as PM-bearing materiel but that, on the basis of experience or visual 

inspection, is suspected of containing PM. Assistance can be obtained from the PM master file 

or items identified by NSN; through actual chemical testing of the materiel following prescribed
