SRRC Certification

Basis for a MII / NAL certification

The SRRC label is primarily a word mark and represents the CMIIT ID that the manufacturer receives from the agency as part of the approval process. Here it is important to note that without a CMIIT ID, no product may be imported into China and distributed there.

Core parameters for products with wireless technologies

The necessary tests must be carried out in a test laboratory accredited by the Ministry of Industry and Information Technology (MIIT). The authority responsible for this is the State Radio Monitoring and Testing Center (SRTC). Part of the SRRC certification is the determination of core parameters of the products with radio technologies.

These include:

  • Frequency
  • frequency band
  • transmit power
  • frequency tolerance
  • Occupied bandwidth
  • Parameters of the frequency spectrum (such as out-of-band emissions)

Only after a successful SRRC certification can an application for NAL certification be made,
since the test results of an SRRC certification are the basis for NAL certification.

Products requiring SRRC certification include cell phones (GSM or CDMA),
wireless LAN (WLAN) devices, and devices using the following technologies:

  • WLAN
  • Bluetooth
  • ZigbeeWiMAX
  • RFID

In the case of SRRC certification, it should be noted that the government agency verifies the frequencies selected for the product, so the manufacturer is required to correctly specify the frequencies used by the device. Therefore, in order to obtain approval, the transmit power, bandwidth and scattered radiation must meet the requirements of the selected frequencies. In addition, some frequencies are not publicly available in China and this restriction must also be taken into account by manufacturers.

Basic information for SRRC certification

Validity 5 years
Lead time 10 to 12 weeks
Local tests required Yes
Local representative required No
Approval label required Yes


In summary, it can therefore be said that manufacturers have to cope with different certification scenarios based on their products and the technologies used there. Here it is advisable to rely on an experienced partner who can already provide support in identifying the necessary certification regimes and the relevant scope of testing.
