UL & CSA Approved Labels: Markings, Approved Materials and Key Differences

Posted by Butler Technologies on March 17, 2025

In today’s competitive marketplace, product safety and compliance are essential for gaining consumer trust and meeting regulatory requirements. UL and CSA-approved labels serve as crucial certifications that indicate a product has met stringent safety and performance standards. These labels assure customers that the product has undergone rigorous testing and is suitable for use in various industries.

Whether your products are intended for domestic or international markets, obtaining the right safety certifications enhances credibility and ensures compliance with industry regulations.

What Are UL & CSA Labels?

UL Label

Underwriters Laboratories (UL) is one of the most recognized safety science organizations globally. UL tests and certifies products to ensure they comply with North American safety regulations. 

A UL mark is placed on a product only after it has successfully undergone rigorous safety testing and met the required safety standards. UL labels are commonly found on electrical appliances, fire safety products, performance testing equipment, food safety products, and water enhancement devices. 

UL certification is essential for ensuring that products meet North American safety standards, providing consumers with confidence in product safety and regulatory compliance. This certification is primarily recognized in the United States and is widely used for regulatory approval within the U.S. market.

CSA Label

The Canadian Standards Association (CSA) is another major certification body, particularly relevant for products sold in Canada and internationally. Unlike UL, which primarily focuses on U.S. standards, CSA certification is globally recognized, making it ideal for companies looking to expand beyond the U.S. market. 

CSA labels indicate that a product has been tested for compliance with North American safety standards. These labels are commonly required for electrical appliances, medical equipment, industrial machinery, gas appliances, plumbing fixtures, personal protective equipment (PPE), and lighting products. 

A CSA certification is recognized and accepted in both the United States and Canada, demonstrating compliance with North American safety regulations. However, some CSA certification marks are specific to Canada, such as the CSA Special Inspection Label, which is applied to electrical products tested under Canadian safety requirements.

UL & CSA Approved Markings

UL & CSA Markings and Approved Materials

Understanding UL & CSA Markings

UL and CSA labels contain specific markings that signify a product’s compliance with safety standards. These include:

  1. UL Listed Mark – Indicates that a product has been tested and meets UL’s safety standards for specific applications.
  2. UL Recognized Component Mark – Used for components that are part of a larger system but do not carry the full UL listing.
  3. CSA Certified Mark – Indicates compliance with Canadian safety standards and, in some cases, additional international standards.
  4. UL Classification Mark – Applied to products that have been tested for specific hazards or performance criteria.
  5. CSA-US Mark – Demonstrates that a product meets both CSA and U.S. safety requirements, facilitating broader market access.

UL & CSA Approved Materials

For labels and decals to comply with UL and CSA standards, they must be made from durable materials capable of withstanding environmental conditions. Commonly approved materials include:

  • Polyester (PET) – Offers high durability, chemical resistance, and excellent adhesion.
  • Vinyl – Flexible and weather-resistant, making it suitable for outdoor applications.
  • Polycarbonate – Provides high-temperature resistance and mechanical durability.
  • Acrylic – Ideal for applications requiring clarity and strength.
  • Laminated Labels – Used for added protection against moisture, UV exposure, and abrasion.

UL 969 is the specific standard that governs label performance, ensuring that they remain legible and adhered to surfaces over time, even under extreme conditions.

For companies operating primarily in the U.S., UL certification may be sufficient. However, businesses aiming for global distribution may benefit from CSA certification due to its wider acceptance.

Importance of UL & CSA Approved Labels

  1. Compliance with Safety Regulations – Many industries require UL or CSA certification to meet Occupational Safety and Health Administration (OSHA) standards.
  2. Enhanced Product Credibility – Certified products gain consumer trust and confidence.
  3. Market Expansion – CSA certification allows businesses to sell products globally without facing regulatory hurdles.
  4. Insurance & Liability Protection – Many insurance providers require UL or CSA certification before offering coverage for equipment and machinery.
