Performance and Certification. Simplified.

Plastics manufacturers need to put their products to the test to ensure rigorous safety standards are met, as well as the performance expectations of OEMs. The UL Yellow Card is a globally recognized safety and quality guarantee – and a low-maintenance marketing tool.

  • Globally respected safety certification and quality information card
  • Additional performance credentials (eg. RoHS or non-Hal) verify industry requirements
  • Attached White Card associated to international standards for promotion to global markets
  • Available digitally via and

The UL Yellow Card lists multiple safety and performance-related properties for a polymeric material tested by UL to appropriate standards, and can also include additional performance credentials (eg. RoHS or non-Hal), which verify industry requirements. It provides substantiation that a material is appropriate for specific applications and helps ensure that the manufacturer is using a tested and certified material, as well as being monitored at regular intervals by an independent test laboratory.

How to get a UL Yellow Card


A Yellow Card is automatically issued when polymeric materials have successfully undergone UL testing and receive a UL Recognized Component Mark. UL testing includes:

  • Ignition and burning characteristics from thermal and electrical sources
  • Electrical, physical and mechanical characteristics
  • The effect of exposure to elevated temperatures, cold, water, ultraviolet rays, chemical fluids, etc.

The benefits of the UL Yellow Card

Material manufacturers use the UL Yellow Card to promote the safety and quality of products to markets and existing or potential customers. Yellow Cards are listed in the UL iQTM database and UL’s Prospector® database, which are used by thousands of designers, engineers, and suppliers to find providers of verified materials and components. The Yellow Card helps shorten the path for manufacturers seeking certification for their end-products or systems. Using UL tested and certified components, identifiable through the UL Recognized Components Mark on the Yellow Card, can save time and money by eliminating the need for further material testing.

The White Card – boosting product discoverability

UL Yellow Cards are not limited to safety certification. Manufacturers can add value by increasing coverage to include the performance properties customers are looking for – all backed up with third-party verification. The White Card, an extension at the bottom of a Yellow Card, allows manufacturers to promote their product‘s performance credentials to the global markets. It relates to international standards, while the information on the Yellow Card is typically relevant
to North America.
