UL Solutions certification indicating a product has been tested and meets UL safety standards.
UL Listed means an independent safety lab (UL Solutions) actually tested the product and confirmed it's safe. Unlike CE, this is a genuine third-party certification — not self-declaration. It's not legally required by US law, but many building codes, retailers, and insurers require it.
