China: Navigating New SRRC Regulations

What manufacturers need to know about new regulations for radio transmitting equipment in China.

The Chinese Ministry of Information Technology (MIIT) has introduced new regulations affecting the type approval process for radio transmitting equipment, effective from October 15th, with a two-year transitional period. These regulations, outlined in Regulation No. 129, impose additional tests for wireless equipment and modules, with existing China SRRC Certificates requiring updates by the end of 2025. Key technical requirements introduced include “pre-transmission scanning,” “monitoring and avoidance,” and “Medium Utilization (MU)” for equivalent occupancy rate.

Understanding MIIT Announcement No. 129: Implications for Manufacturers

Manufacturers and importers of radio transmitting equipment in China must adhere to new regulations issued by the Ministry of Industry and Information Technology (MIIT). MIIT’s Announcement No. 129, effective from October 15th, 2023, mandates compliance with technical requirements such as “pre-launch search,” “monitoring and avoidance,” and “equivalent occupancy rate” for wireless transmission equipment. SRRC certificates obtained before October 15th, 2023, remain valid until December 31st, 2025, with updates required for continued product sales after this date. 

Insights into MIIT Announcement No. 129 and Its Impact

MIIT’s Announcement No. 129, published on October 14, 2021, introduces significant changes to radio management in China, particularly in the 2400MHz, 5100MHz, and 5800MHz frequency bands. These changes aim to ensure frequency compatibility, improve anti-interference capabilities, and optimize frequency resource utilization. The announcement emphasizes new interference avoidance technical requirements, raising testing fees accordingly. Existing SRRC certificates remain valid until December 31st, 2025, necessitating certification upgrades for continued product sales thereafter.
