SRRC Filing Timelines for a Product Entering China
SRRC radio type approval in China takes 8 to 16 weeks, requiring local agent representation, strict customs sample clearing, and accredited domestic lab scans.
MIIT Filing
Meaning
Administrative submission to the Chinese central government agency documents the radio equipment specifications and production capability of a manufacturer. The miit filing acts as the official request for entry into the Chinese domestic wireless hardware market. It contains test reports from local facilities, internal circuit diagrams and high-level descriptions of the device function.
This document must be complete before any commercial distribution can occur inside the national territory.
Certification Chain
Completing a miit filing starts after initial radio tests are finished at a designated technical laboratory. The government department cross-references the filing with the results of the specific radio test reports. Approval results in the formal issuance of the identifier that appears on the device exterior.
Any changes to the hardware require a new filing or an update to the previously recorded specifications.
Document Scope
Every entry includes technical parameters like frequency range, modulation type and maximum radiated power. A successful miit filing provides the manufacturer with the legal right to participate in regional network auctions or private trade. The agency looks for compliance with data security and spectrum use regulations during the evaluation.
This paperwork links the serial numbers of individual batches to a verified regulatory grant.
Approval Integrity
Maintaining an accurate miit filing avoids potential fines or sales bans if the hardware is later found to be non-compliant. Access to the online database allows regulators to verify thousands of device records instantly. If the registered power exceeds legal limits, the agency requires a resubmission.
Proper filing provides transparency for consumers and network operators regarding the source and capability of the equipment.
