ETL vs. UL:
products issued ETL certification and UL certification can be sold to the United States and Canada markets, follow-up to accept regular factory supervision and inspection to maintain the validity of the certificate.
Both certifications are voluntary. ETL certificates will expire with the expiration of UL/CSA standards and cannot continue to apply for the old standards. UL certificates can continue to be inquired on UL websites after the standards expire, and relevant filing applications can be made for old standards under appropriate circumstances.
