UL / cUL Labels

UL compliant labels are made with materials and designs that have been approved by Underwriters Laboratories, an independent nonprofit known as the leading authority on electrical safety standards in the U.S. UL regularly tests and certifies products to make sure they meet strict safety and performance requirements. At Steven Label, our engineering team develops durable labels that meet UL and cUL standards. These requirements can be complex and sometimes costly to implement. With our experience and wide range of certified solutions, we help customers find the most effective and compliant labeling options for their products. For more information about our UL certified labels and detailed guidance on UL requirements, please visit the official UL Solutions website.

Features

Recognized materials and adhesives

UL/cUL labels are produced with certified materials and adhesives that meet stringent safety, durability, and performance standards required for regulated environments.

Resistance to harsh conditions

These labels are engineered to withstand exposure to chemicals, cleaning agents, moisture, UV light, and elevated temperatures common in medical facilities and industrial operations.

Permanence of marking

UL requires that all safety and certification markings remain legible and intact over the equipment’s service life, even under routine cleaning, abrasion, and sterilization.

Traceability and compliance identification

Each label includes UL/cUL marks, file numbers, and sometimes serial data, demonstrating that the product has been evaluated for compliance with applicable standards in both the U.S. and Canada.

Tamper resistance and security options

For applications requiring security or warranty protection, UL/cUL labels can be produced with tamper-evident features to discourage removal or alteration.
