There are approximately 13,000 (active/inactive) producers and/or suppliers listed with the Department of Transportation. Updated monthly, the current List of Producers and/or Suppliers provides an alphabetic and a numerical listing including producer/supplier number, name and location.
Producers and/or Suppliers interested in providing materials to be used in construction projects must first obtain approval by the department.
Please note
Producer and/or suppliers may be classified as "inactive" or "d-flagged" for several reasons which include: producer/supplier going out of business, lack of providing material for several years, material problems, etc. but have the capability of becoming "active" status again by complying with the requirements as stated in the appropriate material policy memorandums
