Look for the UL safety Mark before you buy

The UL Mark means a product has been certified to meet scientific safety, quality or security standards.

If we sound or look familiar, but you can’t put your finger on it, it’s because the UL safety Mark appears on more than 22 billion products around the world each year. It’s the single most accepted certification Mark in the United States. From appliances, smart devices and furniture to home construction material and fire and carbon monoxide detectors, the UL Mark is a symbol of trusted safety and performance. 

The UL safety Mark means a product has been certified to meet scientific safety, quality or security standards. We also continue to check products months and years after testing to make sure they still meet the requirements. Look for UL safety Marks on product packaging, the product itself or within product details when shopping online.  

Although there are many variations of our safety certification Marks, they typically look like one of the following:
