Introduction to etl certification  

ETL stands for Electrical Testing Laboratories, founded by Thomas Edison in 1896. It is recognized as a Nationally Recognized Testing Laboratory (NRTL) by OSHA (Occupational Safety and Health Administration) in the United States. After more than 100 years, the ETL mark is widely recognized and accepted by major North American retailers, enjoying a reputation comparable to UL. The North American market has the most advanced and comprehensive product testing standards, and the certification requirements are quite stringent. Any electrical, mechanical, or electromechanical product bearing the ETL mark indicates it has been tested and meets relevant industry standards.

Is a Factory Inspection Required for ETL Certification?  

For first-time applicants, a factory inspection must be completed before obtaining the ETL certificate to ensure product consistency and proper use of the ETL logo. Afterward, quarterly follow-up factory inspections are conducted, with additional costs for the factory inspection and quarterly certificate/license fees.
