Normally, charges for services rendered will be based upon the standard rates established by the agency for internal use. However, special rates may be negotiated to cover actual or estimated costs for large, bulk lots of material when the applicable rates appear inequitable, subject to the approval of the appropriate program official for the civilian agency, and the Assistant Secretary of Defense (I and L) when DOD is involved.
