[*see DoD deviation below]
(a) If the contractor has an approved purchasing system, consent is required for subcontracts specifically identified by the contracting officer in the subcontracts clause of the contract. The contracting officer may require consent to subcontract if the contracting officer has determined that an individual consent action is required to protect the Government adequately because of the subcontract type, complexity, or value, or because the subcontract needs special surveillance. These can be subcontracts for critical systems, subsystems, components, or services. Subcontracts may be identified by subcontract number or by class of items (e.g., subcontracts for engines on a prime contract for airframes).
(b) If the contractor does not have an approved purchasing system, consent to subcontract is required for cost-reimbursement, time-and-materials, labor-hour, or letter contracts, and also for unpriced actions (including unpriced modifications and unprice delivery orders) under fixed-price contracts that exceed the simplified acquisition threshold, for-
(1)* Cost-reimbursement, time-and-materials, or labor-hour subcontracts; and
(2) Fixed-price subcontracts that exceed-
(i) For the Department of Defense, the Coast Guard, and the National Aeronautics and Space Administration, the greater of the simplified acquisition threshold or 5 percent of the total estimated cost of the contract; or
(ii) For civilian agencies other than the Coast Guard and the National Aeronautics and space Administration, either the simplified acquisition threshold or 5 percent of the total estimated cost of the contract.
(c) Consent may be required for subcontracts under prime contracts for architect-engineer services.
(d)* The contracting officer’s written authorization for the contractor to purchase from Government sources (see Part 51) constitutes consent.
