Introducing the USB Type-C certification process

Recently, many customers have encounteRED issues with shipments to the U.S. being detained by customs for inspection and identified as infringing products. Typically, customs require the exporter to provide authorization from the USB Trademark holder, known as the TID Number authorization.

Type-C Certification

With major brands adopting the Type-C interface, related products now constitute a significant portion of the consumer electronics market. Here are the details on how to obtain Type-C certification and the approximate costs involved.

USB Trademark Usage

Type-C is part of the USB Association family. The USB Association has evolved from USB 1.0 to USB 3.1, each with distinct authorized logos. USB imposes clear requirements on the packaging, promotional materials, and advertising of products to ensure consistent terminology and imagery, avoiding any consumer confusion.

Becoming a USB-IF Member

Manufacturers must become members of USB-IF (USB Implementers Forum) to produce USB products. This involves applying, signing an agreement, and paying an annual fee. Membership details can be found on www.usb.org. For USB cable assembly certification, samples must be tested, and the USB membership number and UL2725 certification for the cable must be provided. Upon successful testing, a TID Number is issued.

Cable Components:

- USB2.0 Type-C Plug (12 pin)

- USB Full-Featured Type-C Plug (22 pin)

- USB Type-C Receptacle

- USB Type-C Receptacle + C-Plug (22 pin)

Note: Type-C is not synonymous with USB 3.1. While Type-C cables and connectors supplement USB 3.1, they do not inherently support USB 3.1 standards or USB Power Delivery unless specified by the manufacturer.

USB Logo Usage

In addition to graphic symbols, the USB Association has introduced text identifiers “USB Type-C” and “USB-C,” which must be used only on products meeting the Type-C cable and connector specifications. These trademarks must be included on all materials, and cannot be translated into languages other than English.

USB IF Product Certification Process

1. Contact the Chinese JJR laboratory for certification testing.

2. Prepare samples and documentation.

3. Document review.

4. Pre-testing.

5. If pre-testing passes, proceed to formal testing. If it fails, analyze and resolve issues before re-entering the application process.

6. Formal testing.

7. Submit test reports to USB-IF for review. If formal testing fails, revise documentation and reapply starting from step 3 until successful.

8. USB-IF publishes the TID.
