A ULC or UL mark on a product means that ULC or UL has tested and evaluated representative samples of that product and determined that they meet ULC/UL’s requirements. In addition, products are periodically checked by ULC/UL at the manufacturing facility to make sure they continue to meet ULC and/or UL requirements.
There are several types of UL and ULC Marks. Each has its own specific meaning and significance. The only way to determine if a product has been certified by UL or ULC is to look for the UL and /or the ULC Mark on the product itself. In a few instances, the UL or ULC Mark may be present only on the packaging of a product.
The ULC Mark may be only used on or in connection with products certified by ULC and under the terms of written agreement with ULC.

In addition to these marks, ULC and UL also provide access to the marks required in a number of other key world markets.
