    Updated On: Dec 342, 2022

    According to UL, the following warning signs may be indicative of a product that does not have UL Listing:

    • A product whose label does not contain these 4 elements:
      • The familiar UL symbol (the UL in a circle) or other specific formats authorized by UL
      • The word “LISTED”
      • The product identity
      • A unique control number or serial number assigned by UL
    • Any product that references UL on the carton or on the product itself but has no company name or address
    • Any product that references UL on the carton, but not on the product itself
    • Cheap, low-quality workmanship and/or packaging.
    • Marks with the letters “UL” side by side instead of staggered, the lack of a control number, or the words “Approved” or “Pending” instead of “LISTED” or “CLASSIFIED”
