UL VS ETL certifications

1.Is the ETL Listed Mark legal equivalent to the UL and CSA Listed Marks?

The true legal requirement to test and certify products for sale in the United States is a designation by the Occupational Safety and Health Administration (OSHA) as a Nationally Recognized Testing Laboratory (NRTL). An NRTL functions to provide independent evaluation, testing, and certification of any electrically operated or gas- and oil-fired product. ETL is recognized as an NRTL in the United States and, in a similar capacity, as
a Testing Organization and Certifying Body in Canada by the Standards Council of Canada.
A product bearing the ETL Listed Mark is determined to have met the minimum requirements of prescribed product safety standards. Moreover, the mark indicates that the manufacturer's production site conforms to a range of compliance measures and is subject to periodic follow-up inspections to verify continued conformance.

2.What's the difference between the UL, CSA, and ETL Listed Marks? Both marks demonstrate that the product that bears it has met the minimum requirements of widely accepted product safety standards as determined through the independent testing of a Nationally Recognized Testing Laboratory (NRTL). And, as part of that testing regimen, the product manufacturer has agreed to periodic follow-up inspections to verify continued compliance.

3.What is an NRTL?
A Nationally Recognized Testing Laboratory (NRTL) is an independent laboratory recognized by the Occupational Safety and Health Administration (OSHA) to test products to the specifications of applicable product safety standards – such as those from Underwriters Laboratories (UL) and other standards-writing bodies. An NRTL's function is to provide an independent evaluation, testing, and certification of any electrically operated or gas- and oil-fired products.

in CKRA, all of our fixtures come with ETL listed in order to meet U.S and Canada’s requirements. ETL is much faster than UL when we applying the certification from them.
