Frequently Asked Questions

What is the difference between ETL and UL certification?

There is no functional difference between ETL and UL certification. Both are issued by Nationally Recognized Testing Laboratories (NRTLs) recognized by OSHA. They test to the exact same standards (e.g., UL507), have the same legal status, and offer the same level of product safety assurance for the North American market.

Is ETL certification accepted in the U.S. and Canada?

Yes, ETL certification is fully accepted throughout the United States and Canada. All major retailers, distributors, government agencies, and commercial/industrial businesses recognize ETL certification as equivalent to UL. This includes major retailers like Walmart, Home Depot, and Best Buy, as well as government procurement and industrial applications.

Can you provide ETL certification documentation?

Yes, we can provide ETL certificates and Intertek test reports upon request. Please contact our sales or technical support team for specific product certification documentation. We maintain comprehensive records of all our product certifications and are happy to share these with our customers and partners.

Why did LONGWELL choose ETL instead of UL certification?

LONGWELL chose ETL certification because it offers the same level of safety certification as UL but with more flexible service delivery and often quicker turnaround times. Since both organizations are OSHA-recognized NRTLs and test to identical standards, the certification marks are completely equivalent. This allows us to bring compliant products to market efficiently while maintaining all safety requirements.
