What is USB C TID Certification?

Products that use USB logo needs TID's association certification. This test is intended to ensure that the quality of all USB C Cable meets the requirements.

TID Certificated USB C Cable means top quality and Quality approval from the USB-IF Association.

1. TID's association certification test comes from the USB-IF Association.

In order to support and promote the market and users' recognition of USB-compatible peripherals, Intel established the USB Implementers Forum (Universal Interface Industry Association, referred to as USB IF) with industry peers in 1995. At present, USB-IF has accepted more than 10,000 corporate members , with board members from Agere Systems, HP, Intel, Microsoft, NEC and Representatives of Philips. The current board members have changed to HP, Intel, Juji, Microsoft, Renesas Electronics, and ENFA Semiconductors.

The USB Implementers Forum (USB-IF) is a non-profit organization dedicated to promoting and developing Universal Serial Bus technology. The USB organization provides standard transmission interface specifications that make the connection between computers and peripheral devices much easier. Information products generally applied to USB include printers, keyboards, screens, network devices, scanners, etc. USB IF itself is a voluntary logo certification.

2.  USB Type-C now has occupied a large market of USB cables, and the USB Type-interface has become the new favorite of the market. Due to the release of high-power specifications such as PD3.1 and 240W, high-speed USB cables have replaced traditional power cables. , is widely used to power and charge IT and communication equipment such as notebook computers, tablet computers, mobile phones, mobile power supplies, etc. The function of mobile phone data transmission has been basically compressed to a very small existence, so in order to meet the needs of high-speed charging and high-power equipment The power capacity of the USB cable is constantly increasing due to the need for power supply. However, in the actual application process, users may not know that the use of cables with poor structure or hidden quality is often accompanied by potential overheating, overload and fire risks. For example, some cables have poor flame resistance and heat resistance due to the use of non-compliant materials, the connector design does not meet the specifications, the cable and the connector are not connected according to the specifications during wiring, or the assembly of the cable cannot carry the required current. The association has issued new regulations, requiring that products supplied by regular channel sellers must use products certified by USB membership, brand owners need to have VID, and manufacturers need to have VID and TID.

3.  Apple put TID into MFI standard：

Different from the previous certification of USB-A to Lightning cables, Apple has added a threshold to the MFi certification process of USB-C to Lightning cables, that is, USB-C connectors must be certified by the USB-IF Association and require Provide the corresponding TID number.

In the email sent by Apple to MFi companies, it is clearly pointed out that "The USB-C plug must have an assigned Connector Test ID from the USB-IF." (USB-C connectors must have the TID of the USB-IF Association).
