Submit Your Industrial Control Product to UL

The first step in submitting your product is to determine the UL office closest to you. For details on the location of our offices, consult our Global Resources or Locations pages. If you are an existing client, please contact the office you normally work with.

Next, mail, fax or e-mail a letter to one of our customer service representatives describing your product. By including more preliminary information at this stage, you will help us to quickly determine cost and time estimates and a tentative test program. Use the following checklist for a guide on the type of items to include:

  • List of product series and/or models within each series, including input and output ratings of each model and a description of how each model differs;
  • Instruction manual or installation instructions;
  • Promotional literature;
  • Schematics;
  • Color-coded voltage maps; and
  • List of components that are upstream from protective devices such as MOVs, and fuses; (should include manufacturer, part number, ratings, and whether or not device is UL Listed or Recognized).

If you are new to UL, the third step in the submittal process is receiving the application form UL sends you and returning it to us. Once we receive the signed application form, preliminary deposit, and additional information and/or samples, we can complete a typical investigation within four to six weeks.
