UL Mark Surveillance

Overview

UL’s UL Mark Surveillance also known as Follow-up Service (FUS) distinguishes UL from other certification service providers and is fundamental to the integrity of the UL Mark.

We protect our customers' investment in our certifications by maintaining an ongoing business relationship with manufacturers using the UL Mark.
Throughout the lifetime of a certification, UL’s Field Engineers conduct factory audits and blind sampling of certified products chosen from the open market to assess continued compliance with UL requirements. By protecting the integrity of UL certifications, we add real value to our customers' brands.

We share a common goal with our customers in ensuring only those products fully complying with UL’s requirements carry the UL Mark.

We also offer customized on-site support and training to help customers prepare for their first UL Mark surveillance visit.
