UL Certification for Electronics Sourced from China
2 resources tagged with "Ul"
UL certification is the de facto safety requirement for electronics sold in North America, with chargers and power supplies typically tested to UL 62368-1. A key distinction is UL Listed (a complete, end-product certification) versus UL Recognized (a component intended to go inside another product), and buyers regularly confuse the two when reading a China factory's certificate. Genuine UL marks are traceable in UL's online Product iQ database against a file number.
When you source UL-marked goods from China, the recurring fraud is a recycled or forged UL file number that does not match the actual product. We verify the file number in UL Product iQ and confirm the certified model matches what is in the carton.

FAQ
What is the difference between UL Listed and UL Recognized?
UL Listed covers a finished end-product the consumer uses directly; UL Recognized covers a component (like an internal power supply) meant to be built into another product. A Recognized component alone does not make the final product UL Listed.
How do I verify a China factory's UL certificate is real?
Look up the UL file number in UL's Product iQ database and confirm the company name and exact model match. A certificate image with no verifiable file number is a red flag.
