The UL Yellow Card Plastics Recognition Program

What is a UL Yellow Card?

The UL Yellow Card (or Plastics Recognition Program) provides a digital product information card that lists substantial safety and performance-related properties for a polymeric material that UL tests to applicable standards. UL automatically issues a Yellow Card when polymeric materials receive a UL Recognized Component Mark.

The additional UL White Card provides information concerning testing performed to international standards (ISO, IEC).

Certified materials appear in the UL Product iQ® and UL Prospector® databases, which thousands of designers, engineers, and suppliers use to find recognized material and component providers.

Benefits for material manufacturers

The Yellow Card provides the ideal recognition for manufacturers of materials or components to promote products and their tested properties to global markets and potential customers.

Benefits for material users

The Yellow Card provides confidence that a material will continue to meet requirements for specific applications. Using UL tested and certified components — identifiable through the UL Recognized Component Mark on the Yellow Card — can help save time and money. Eliminating the need for further material testing can shorten the path to certain certifications.
