Defense Priorities and Allocations System

The Defense Priorities and Allocations System (DPAS) is a regulatory program administered by the Department of Commerce under authority of the Defense Production Act (DPA) that assigns mandatory priority ratings to defense, emergency preparedness, and critical infrastructure contracts, legally requiring suppliers to prioritize rated orders over unrated commercial business.

What is DPAS?

DPAS was established under the Defense Production Act of 1950 and the regulations at 15 C.F.R. Part 700. It creates a mandatory ordering system for the defense industrial base: when a government contractor receives a "rated order" with a DPAS priority designation, the contractor must: (1) accept the order (unless acceptance is impossible); (2) schedule and produce the rated order ahead of unrated commercial orders; and (3) flow down the DPAS rating to subcontractors and suppliers in the supply chain.

DPAS uses two priority rating levels. "DO" ratings (Department of Defense Obligation) are the more common designation for standard defense contracts. "DX" ratings are the highest priority level, reserved for critical national defense programs. Within each rating level, orders are prioritized by date received (earlier orders have priority over later orders). DPAS-rated orders take precedence over all unrated commercial orders, regardless of the commercial order's size or the customer relationship.

The rating is communicated through specific clauses in the contract: FAR 52.211-14 (Notice of Priority Rating for National Defense, Emergency Preparedness, and Energy Program Use) places the DPAS rating designation on the contract, and FAR 52.211-15 (Defense Priority and Allocation Requirements) establishes the contractor's obligations. The prime contractor must include these clauses (with the applicable rating designation) in its subcontracts.

DPAS becomes particularly important during supply chain disruptions, defense emergencies, or periods of high demand when the defense and commercial sectors are competing for the same materials, components, or manufacturing capacity. During COVID-19 supply chain disruptions, DPAS ratings helped defense contractors maintain production by asserting priority for constrained materials against competing commercial demand.

Why DPAS matters for defense contractors

DPAS-rated orders are not optional, accepting them is legally mandatory and prioritizing them above unrated commercial work is required by law. Defense contractors must understand DPAS both to comply with their own obligations and to use the system to obtain priority treatment from their own supply chains.

Example

A defense electronics manufacturer holds a DX-rated contract for fire control systems for a priority Army program. When semiconductor shortages hit in 2025, the manufacturer's primary chip supplier is also producing chips for commercial automotive customers. The defense manufacturer invokes its DX-rated purchase orders to the chip supplier, who is legally required to prioritize these orders over the unrated automotive supply agreements. The chip supplier delivers defense-rated orders first, allowing the Army program to maintain its production schedule while the automotive customers experience delivery delays.

Frequently Asked Questions

Can a company refuse a rated order?

Generally no. Under DPAS regulations at 15 C.F.R. § 700.13, a person must accept every rated order received unless acceptance is impossible because the required item is not normally supplied or is not available within the time frame required. A company may not refuse a rated order because filling it would require delaying unrated commercial work, that is exactly what DPAS is designed to do. Failure to accept or prioritize a rated order is a violation that can result in civil and criminal penalties.

How does DPAS flow down the supply chain?

Primes with rated orders are required to flow the DPAS rating down to their subcontractors and suppliers through the rated order clauses. The subcontractor then faces the same mandatory acceptance and prioritization obligations as the prime. The DPAS rating propagates through multiple tiers of the supply chain, a Tier 3 component supplier may receive a rated purchase order from a Tier 2 subcontractor and face the same legal obligations as the Tier 1 prime.

Are DPAS ratings common on defense contracts?

DO ratings are very common on defense contracts, most contracts for defense items and services above the micro-purchase threshold carry DPAS DO ratings. DX ratings are less common; they are reserved for programs the President has specifically designated as highest national defense priority, typically in a Presidential Determination. Not all contractors notice or pay attention to the DPAS clause on their contracts, but the legal obligations apply regardless.

Can DPAS be used during natural disasters or domestic emergencies?

Yes. The Defense Production Act, under which DPAS operates, was specifically amended after Hurricane Katrina to authorize use of DPAS for emergency preparedness purposes in addition to defense. FEMA and DHS can invoke DPA authorities to prioritize orders for disaster response supplies and equipment. During COVID-19, the DPA was invoked to prioritize production of ventilators, PPE, and vaccines.
