MII / NAL Certification

NAL certification issued by the Ministry of Industry and Information Technology (MIIT) is essential for telecommunications products connected to the public telecommunications network.

For foreign manufacturers, NAL certification is mandatory for telecommunications products before a product can be imported and marketed in China.

The first product categories for NAL certification were introduced in 2001, now there are 28 categories from three different main groups:

  • Telecommunications terminal equipment
  • Radio communication equipment
  • Telecommunications equipment for inter-network connectivity

Over 300 telecommunications products are now defined in the categories. These include communication or network devices with interfaces to public networks or Wide Area Network (WAN) services. Common communication interfaces include T1/E1, ISDN BRI, ISDN PRI, ADSL, serial and analog PSTN.

If an NAL approval is necessary for a product, this means that a CCC certification is also required for this product. In addition, SRRC certification is a prerequisite for NAL approval. The SRRC certification is – analogous to the CCC certification – issued by the State Radio Monitoring and Testing Center. An SRRC certification is relevant for all products that use a radio transmitter in any form.

The necessary tests must be carried out in a test laboratory accredited by the Ministry of Industry and Information Technology (MIIT). The responsible authority is the State Radio Monitoring and Testing Center (SRTC).
