In cooperation with National Technical Systems (NTS) located in the United States, we are pleased to announce that STC (Hong Kong Standards and Testing Centre) has completed the agreement with NTS to launch the unique USB compliance testing service here in Hong Kong.

We tend to serve all Hong Kong, China and overseas device manufacturers to get the USB logo as well as pre-compliance test and lab rental for debugging the USB products.

With fast turn around time, the compliance test can be completed within a week, while certification application may take longer (dependent on the USB-IF acceptance duration). STC is a one-stop shop for USB, EMC, FCC, Energy efficiency and Electrical Safety testing.

Any products that come with USB port(s) such as electronic devices, audio video products, IT products, etc. are subject to USB testing if you want to mark the USB logo on the product (provided that the product meets USB-IF guidelines).
