UL Taiwan USB Test Lab

Our USB-IF certification and testing program helps ensure product compliance associated with the USB Type-C™ connector. We focus on the reliability of data transmission, cable and connector design, and the proper implementation of Power Delivery (PD).

Massive arrays of devices now rely on USB Type-C for connection, communication and power. Now more than ever, the industry needs the ability to distinguish a compliant USB cable, device or charger from a substandard one.

Our USB Implementers Forum Inc. (USB-IF) certification and testing program can reassure you — whether you’re a brand owner, installer, retailer or end user — about the reliability of the data transmission rate, the cable and connector design, and the proper implementation of PD. 

With a view to address these concerns, we join the efforts of USB-IF to help ensure product compliance associated with the USB Type-C connector through the testing and evaluation of the USB Type-C cable assemblies, connectors, PD chipsets and power bricks for USB-IF certification. 

Our laboratory in Taiwan has been authorized as an Independent Test Lab (ITL) by USB-IF. UL has previously been qualified for testing USB types A and B cable assemblies and connectors.
