Established in 1903, UL is an independent organization that writes specific standards and tests products against these standards. The mission of UL is to promote a safe living and work environment. In the US, 72,000 manufacturers produce UL-certified products such as electrical appliances, electronic devices, safety equipment, and products holding or conveying flammable liquids or specific components inside devices. These products must be appropriately labeled for the product’s life to ensure consumer safety. LLT Labels® offers UL-approved thermal transfer ribbon and thermal label combinations that provide excellent resistance to water, acid, chemicals, solvents, abrasion, smudging, and UV exposure.

When a label passes UL testing, it becomes a UL Recognized Component, UL Listed or UL Classified label or product and can display a UL Mark.

A UL Recognized Component manufactures a complete, UL Listed product. This type of label cannot display the UL symbol but features the “Recognized Component Mark.” This type of label is used on products such as switches, power supplies, printed wiring boards, etc.

A UL-Listed label is tested according to nationally recognized Safety Standards. UL Listed products include appliances, computer equipment, furnaces, heaters, fuses, and smoke detectors.

UL Classified products are tested to specific properties or suitability for use under limited or special conditions.
