What are CSA and UL/cUL Labels?
UL and CSA labels provide safety-related information. These certification labels let consumers know that a product has undergone safety testing and is compliant with stringent safety guidelines and specifications. For a product to bear either a UL or CSA mark, not only does the product need to be certified, the label itself must also be certified. That means a CSA-certified product must have a label approved by CSA Group and a UL-certified product must have a label approved by UL.
Many UL and CSA certified products are required to be labeled with information such as warnings, cautions, electrical ratings, installation information, and other types of safety-related information. To ensure that this information remains with the product, UL and CSA labels are permanently fixed to the end product. These labels are then considered a product component. UL or CSA labels need to meet certain criteria related to their construction. These criteria help ensure that the label will remain legible throughout the lifespan of the certified product.
UL (Underwriters Laboratories) is widely regarded as the authority on safety assurance in the US. They are an independent, not-for-profit organization that develops electrical safety standards and regularly tests products for compliance. UL offers various levels of certification, appropriate for different products and requirements.
The cUL mark applies to products intended for the Canadian market that have been tested and found to comply with Canadian standards. Although some of the standards may be similar, it is not necessarily the case that a product certified as UL would meet the cUL standards and vice versa.
DLS is a UL Authorized Label Supplier Program Participant. Our UL approved labels are submitted to UL, who evaluates the design and material to certify that the labels meet durability and content requirements in accordance with their standards. Additionally, we regularly undergo unannounced UL audits to ensure that our labels continue to meet UL standards.
Similar to UL, the Canadian Standards Association (CSA) offers testing and certification indicating that a product has been tested and met applicable Canadian or US safety standards. CSA certification labels can be found on electrical products, mechanical products, or general ‘at risk’ products.
Unlike UL, which is primarily a North American organization, CSA certification is recognized and widely accepted globally—making it a good choice for products that are to be sold outside of North America.
DLS produces and sells CSA certified labels using materials and production methods that have been approved by CSA.
