To indicate compliance, generic ingredients and materials are recognized under UL's Component Recognition and Follow-Up Service programs and identified by the Recognized Mark. The Mark consists of the manufacturer's product designation, corresponding with the marking specified in UL's published records. Such manufacturers may use the Recognized Component Mark, and manufacturers of finished plastic products may use a UL Listing Mark.
