Underwriters Laboratories (UL) is a leading independent safety-science-focused nonprofit organization that approves and certifies product labels. For manufacturers, its certification mark is valuable. 

To apply it, they need a supplier. However, not all have the authorization or capabilities required to print genuine, quality products. By finding the best high-quality UL label suppliers, they can establish a reliable supply chain channel, ensuring integrity and business continuity. 

Understanding UL Recognition and Its Value

As a globally recognized standards company, UL establishes safety guidelines for the design and production of a wide variety of components. The term “UL recognized” refers to parts that are integral to a larger product or system. It signifies the manufacturer followed stringent protocols to maintain compliance with UL standards. 

UL-recognized labels indicate a product has been certified under UL 969 to meet strict safety standards. They comply with PGDQ2 and PGJI2 or PGDQ8 and PGJI8, which are different categories for the United States and Canada. The former applies to marking and labeling systems, while the latter pertains to printing materials. 

These labels communicate certification status. They can provide hazard identification, usage instructions, warnings, electrical ratings or other safety information. Since they assure consumers products have undergone rigorous testing, they are a symbol of trust. 

Criteria to Evaluate When Selecting a Supplier

Some key criteria buyers should evaluate when choosing between the best high-quality UL label suppliers include authorization, printing quality, turnaround times, customization capabilities and minimum order requirements.  

Not all label suppliers are authorized by UL to print labels with the UL certification mark. To ensure integrity and prevent counterfeits, UL Solutions — the for-profit testing and certification arm of the larger UL enterprise — requires suppliers to participate in the Authorized Label Suppliers Program (ALSP). 

UL Solutions sends representatives to each facility that prints or distributes the mark. The suppliers’ names, locations, model numbers and product descriptions are available on the Product iQ certification database. 

Buyers must also consider the quality and durability of the label itself, not just the accuracy of the data on it. How well it permanently adheres to the product — given the application surface, temperature, presence of chemicals and environmental conditions — is crucial information. 

Its look is also critical. Suppliers with customization capabilities can align the color, logo and materials with the application. It is even better if every label is made to order. However, they must not neglect turnaround times. Sales and customer service should respond quickly to questions and requests for quotes. Also, the manufacturing timeline should be clearly defined.

The final criterion is whether or not the business has minimum order requirements. A low minimum quantity makes their product more accessible and cost-effective for small and midsized companies. However, this may not be a deal-breaker for larger corporations.
