Qualified Products List (QPL)

A Qualified Products List (QPL) is a DoD-maintained register of specific commercial products, identified by manufacturer name, product designation, and sometimes part number, that have been tested and certified as meeting a particular military specification, allowing procurement officers to order from the list without requiring additional qualification testing.

What is a Qualified Products List?

When a defense program references a QPL in its solicitation, it means that only products listed on that QPL may be procured for the specified application, or that listed products may be procured without additional qualification testing, while unlisted products must undergo and pass qualification testing before award.

QPLs exist for components and materials where qualification testing is expensive, time-consuming, and technically demanding, lubricants, fuels, fasteners, electronic components, coatings, adhesives, and similar items where military performance requirements cannot be evaluated through simple inspection. The QPL system amortizes testing costs: a manufacturer that qualifies its product once can sell to multiple DoD customers without each customer repeating the tests.

The process for getting a product added to a QPL involves submitting qualification samples to the designated testing laboratory, paying applicable testing fees, passing all required tests, and having the product listed by the managing military service or DLA. Maintaining QPL listing requires continued compliance, the managing agency may conduct periodic surveillance testing to verify that listed products continue to meet specifications, and may remove products from the QPL if surveillance testing reveals non-compliance.

From a business development perspective, QPL listings represent significant value, they create a de facto qualification barrier that unlisted competitors cannot overcome quickly. A company whose product is on a QPL for a widely used specification holds a defensible position in the supply chain for all programs requiring that specification.

Why QPLs matter for government contractors

Products listed on QPLs gain preferred procurement status across all DoD programs requiring the applicable specification. The listing functions as a market access credential, and a qualification barrier against competitors whose products are not yet listed.

Example

A lubricant manufacturer spends $180,000 and eight months qualifying its new military aviation grease to MIL-PRF-23827C. After successfully passing all qualification tests, its product is listed on the MIL-PRF-23827C QPL. Navy aviation logistics officers can now procure the product directly through DLA without additional testing, immediately giving the manufacturer access to grease procurements across the entire naval aviation fleet.

Frequently Asked Questions

Is QPL listing the same as Qualified Manufacturers List listing?

No. A QPL lists specific products (by brand and model) that have passed qualification testing. A Qualified Manufacturers List (QML) lists manufacturers (by facility and process) whose manufacturing processes have been certified, any product they manufacture using those certified processes can be procured. QPLs are product-specific; QMLs are process-specific.

How often does DoD update QPLs?

QPL updates are managed by the responsible military service standardization activity (Army, Navy, Air Force, or DLA depending on the specification). Updates may occur quarterly, semi-annually, or when a significant event (new qualification, removal for non-compliance, specification revision) requires list revision. Current QPLs are available through DLA's quicksearch.dla.mil system.

Can a foreign manufacturer appear on a QPL?

Yes, subject to applicable trade and security restrictions. Products from countries with DoD trade agreements may qualify and be listed on QPLs. However, for specifications covering critical defense components (electronics, certain materials), additional restrictions may limit QPL listing to U.S. or allied nation manufacturers.

What happens if no product on the QPL meets my program's specific needs?

Programs can seek approval to use a non-listed product through a specification deviation or waiver, or can request that the managing activity add qualification testing for a specific non-listed product. Programs may also request specification updates that reflect evolved technical requirements, potentially opening the QPL to new qualifying products.
