Engineering and Technical Services

DLA's Consumable Hardware team prides itself in maintaining a host of programs that assist customers and vendors in an effort to provide optimal, global supply chain solutions to the Warfighter and our Whole of Government partners.

Engineering Programs and Areas

Defense Standardization Program

The DLA Consumable Hardware team participates as a Standardization Management Activity (SMA) in the Defense Standardization Program for consumable hardware commodities and the THDS Standardization Area. We standardize to provide the warfighter with equipment that is interoperable, reliable, and technologically superior at the lowest cost. Items bought to specifications usually require less lead-time, reduced stock levels, and result in fewer back orders. 

Lead Standardization Activity


DLA Consumable Hardware has the Lead Standardization Activity (LSA) responsibility for DLA consumable hardware commodities, and the THDS Standardization Area.

This support involves the approval of standardization project numbers in the generation/modification of standardization documents, coordination review of standardization documents and coordination of standardization documents such as Military/Federal specifications and standards, Non-Government Standards (NGSs), and Commercial Item Descriptions (CIDs). We also look for opportunities to standardize items that are procured by the DLA Consumable Hardware team in order to lower cost and reduce cycle time. For information regarding the Lead Standardization Activity functions, see the appropriate page for the identified NSNs:

Qualified Products List (QPL)


A Qualified Products List (QPL) is a listing of products or family of products that have met the qualification requirements set forth in the applicable specification, including appropriate product identification, tests or qualification reference, and the name and plant address of the manufacturer and authorized distributor. A QPL listing is used by government activities to determine approved sources of supply for items they wish to procure.

The need for QPL is determined by verification requirements in a specification. These requirements can only be justified if:

  • it is determined that time to conduct the tests identified in the applicable specification would exceed 30 days
  • or special equipment not commonly available is required to conduct the tests
  • or the tests are required for emergency life-saving equipment

Further specifics regarding the Defense Standardization Qualified Products Program can be found at the Defense Standardization Program Website

Provisions Covering Qualified Products Lists are found in the SD-6.

An applicant who wants more information or clarification on having their product qualified should:

  • Register for an account at ASSIST
  • Contact the Preparing Activity indicated in ASSIST for the specification they wish to have their product qualified to.


For questions regarding technical difficulty with ASSIST, the official source for specifications and standards used by the Department of Defense, or accessing the website contact the ASSIST team  or click on ASSIST FEEDBACK.
