(1) ETL inspection mark Any electrical, mechanical or electromechanical product with ETL inspection mark indicates that it has been tested to meet relevant industry standards.

(2) ETL listing mark Any electrical, mechanical or electromechanical product with ETL mark indicates that it has been tested to meet relevant product safety standards

ETL certification is the certification required for the export of products to the United States and Canada. The ETL mark indicates that the product has passed the approval test of the NRTL of the United States and or the SCC of Canada. ETL mark recognition has the same effect as UL or CSA mark and complies with relevant safety standards. The product has the ETL listing mark, which means that it has met the minimum requirements of product safety standards. In addition, the ETL logo also indicates that the manufacturer's production site meets a certain range of standard requirements, and ensures continuous consistency by learning the regular follow-up factory review. ETL has been around for more than 100 years. The three letters ETL are the abbreviation of Electrical Testing Labs founded by the inventor Mr. Edison in 1896. ETL represents innovative, influential, independent and open product testing and rich experience.

Difference between UL and ETL

UL and ETL both represent that the products have passed the tests of the National Accreditation Testing Laboratory (NRTL) and meet the corresponding safety standards. So the real difference is service. As a customer of ETL, you can enjoy customized testing, inspection and certification services, fast operation cycle and flexible working methods. We are creating a closer working mode with customers so that your products can enter the market faster, more smoothly and more efficiently.

ETL certification and UL certification have the same market access effect in North America, but the cost of ETL certification is much lower than that of UL certification. Generally, it is only half of that of UL certification. In addition, the product testing of ETL certification can be transferred through the CB test report, which can save you a lot of testing costs.

ETL certification time is also much shorter than UL certification. Under special circumstances, ETL can issue the certificate first, and then conduct factory review to save valuable time for the export of your products.
