Steps

  1. Identify the job's state DOT and locate its materials/QPL page (naming varies: 'Qualified Products List,' 'Approved Products List,' 'APL').
  2. Search the current QPL for the specific manufacturer/product name under the relevant marking-material category (paint, thermoplastic, epoxy, beads).
  3. Confirm the listing hasn't lapsed, since some QPLs require periodic re-testing/re-listing.
  4. If the product isn't listed, check the state's process for submitting a new product for qualification testing before bidding a job requiring QPL compliance.
  5. Document the QPL listing and its date in the bid file.
