For purposes of this ruling, a subcontractor is considered a party to the USG contract if:
(a) the contract expressly authorizes subcontractors to participate in the manufacturing process;
(b) consent to subcontract has been obtained, where required; and
(c) upon request, either the prime contractor or subcontractor produces a copy of the subcontract, award, purchase order, or satisfactory documentation containing the prime USG DOD contract number and demonstrating that the sub-contractor assents to all “flow down” compliance requirements and limitations of the USG contract.
