ETL vs. UL: Understanding the Switch from UL to ETL Certification

Lead Times (1)-1

At MacroAir, we have recently transitioned our product certification from UL (Underwriters Laboratories) to ETL (Intertek's Electrical Testing Labs). This shift signifies a change in the organization responsible for certifying our products' safety and compliance, but what does this mean for our products, our partners, and our customers? Here, we break down the key points of this transition.

Certification Standards

UL: Underwriters Laboratories is one of the most recognized safety certification companies globally. UL develops standards and rigorously tests products to ensure they meet stringent safety requirements.

ETL: ETL, a certification mark provided by Intertek, also tests and certifies products for safety. Importantly, ETL uses the same standards as UL, as it is a Nationally Recognized Testing Laboratory (NRTL) recognized by OSHA (Occupational Safety and Health Administration) in the United States.


Both UL and ETL certifications are widely recognized throughout North America. These marks indicate that a product has been tested and meets rigorous safety standards, providing assurance to retailers, consumers, and regulatory authorities alike.

Process and Efficiency

The decision to switch from UL to ETL often comes down to factors like speed and customer service. Many manufacturers, including MacroAir, have found that ETL offers faster turnaround times compared to UL. This efficiency can be crucial in bringing products to market more quickly and cost-effectively.

Market Acceptance

Products with either the UL or ETL mark are generally accepted by retailers, consumers, and regulatory bodies. Both marks indicate compliance with national safety standards, ensuring that products are safe for use and meet all necessary regulatory requirements.


A product certified with the ETL mark complies with the same safety standards as a product certified by UL. This means that all MacroAir products continue to meet the same stringent safety requirements, ensuring they remain reliable and safe.


UL has a longer history and may have more brand recognition among consumers due to its longstanding presence in the industry. While ETL is equally valid and respected within the industry, it might be less familiar to the general public. Despite this, both UL and ETL marks are equally respected by industry professionals and regulatory bodies.

In Summary

Switching from UL to ETL means that our products will now be tested and certified by a different, yet equally accredited, organization. The products will continue to meet the necessary safety standards and regulatory requirements. This change can offer logistical and service advantages, allowing us to continue delivering high-quality, safe products to our customers quickly and efficiently.

At MacroAir, our commitment to safety and quality remains unwavering. If you have any questions about this switch or need further information, please don't hesitate to contact us.
