Clearing the UL® Label Confusion
-
Underwriters Laboratories Inc.® (UL® ) certification and recognition are often confusing and misinterpreted. These are the separate UL® areas:
- Materials (Recognized Label Component Systems)
UL® tests and certifies label materials against specific safety standards for use on final products required to be UL® approved. See box regarding UL® recognized materials.
- Printing the UL® Mark (UL® bug)
The UL® mark (UL® bug) is a symbol of safety and cannot be used without UL® 's approval. Printed UL® marks that will be placed on a UL® approved product will need to be printed using a Recognized Label Component System.

UL® recognized label component systems
UL® requires you to use a recognized label component system
We offer UL® recognized systems - tested by UL® under file #MH29620. A UL® recognized component is linked to the finished product. The label itself must be a recognized component because it is part of the finished UL® product. Certain combinations of UL® recognized materials and inks that we offer under file #MH29620 are UL recognized label construction, referred to as a component. A UL® recognized label component is not a UL® recognized product. You MUST obtain UL® recognition for your specific product to use the UL® certified marks identifying your product as UL® product.

What is the difference between "UL® Recognized Materials" and "UL® Recognized Component Systems"?
Many label suppliers offer what they call "UL® Tested Materials" or "UL® Recognized Materials", for example, they might offer a UL® recognized polyester base material. Note that this is just a recognition by UL® that the material has met certain criteria. It does not mean that if you use all UL® recognized materials that your final label (base material, adhesive, ink, over-laminate) will be a UL® Recognized Component System. To achieve that status, UL® must test all of the components, at the same time, as one final construction. Please refer to our "UL® Recognized Label Component Systems" info box for this. Be cautious about vendors that say they offer UL® Recognized Component Systems when all they offer is individual UL® Recognized Materials.

MaverickLabel.Com - The Informed UL® Choice !
Ordering UL® labels, components or items with the UL® mark can be a daunting task. We've helped hundreds of companies to find the right UL® solutions. Here's some essential information based on our experience and our customers' experiences with UL®.
UL® Examines, Tests and Reviews Specific Products
Confusion begins when the materials used in a product are looked upon as products in themselves. As an example, what if you needed to design or order a new control panel overlay for an electrical device that was to be made of the polycarbonate Lexan®. Is the control panel certified because it is comprised almost entirely of the UL® certified material Lexan®? For clarification, please read on.
The UL® Certified Mark
Only those products with the UL® mark should be listed and covered by UL®'s Follow-up Service. Always look for the UL® mark on the product.
UL® Recognition
UL® investigates product equipment for the Listing/Classification. Their investigation includes an evaluation of suitability of components, relays, and switches, for use in the specific end product. The acceptability of the Component requires compatibility with the end-product application.
