 China NAL certification 

NAL certification, issued by the Ministry of Industry and Information Technology (MIIT), is essential for telecommunications products that are connected to the public telecommunications network. The NAL label is issued by the MII and consists of the certification number, the model number of the device and a random code on a blue background.

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

Relevant product categories for the NAL certifications

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

  • Telecommunications terminal equipment
  • Radio communication equipment
  • Telecommunication equipment for inter-network connection.

Meanwhile more than 300 telecommunication products are defined in the categories. These include communication or network equipment with interfaces to public networks or Wide Area Network (WAN) services. Common communication interfaces include T1/E1, ISDN BRI, ISDN PRI, ADSL, serial and analogue PSTN.
