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.
Factory Audit Radio Approval
Meaning
Quality control inspections conducted at manufacturing sites ensure that mass-produced wireless equipment conforms to the certified prototype. The process of factory audit radio approval verifies that assembly lines use identical components, shielding, and firmware to those evaluated in the laboratory. This inspection focuses solely on the physical replication of radio characteristics and does not cover general assembly quality.
Compliance is necessary to maintain the validity of the equipment authorization.
Production Consistency
Assembly plants must implement strict controls to prevent unauthorized design changes. During a factory audit radio approval, inspectors check the bill of materials against the original certification filing. Any variance in the RF transceiver chip or the antenna layout requires immediate re-evaluation.
Calibration Routine
Testing equipment on the factory floor must undergo regular calibration against national standards. The factory audit radio approval process verifies that the signal generators and spectrum analyzers used on the line are accurate. This verification prevents faulty transmitters from leaving the assembly plant.
Regulatory Safety
National agencies reserve the right to suspend sales if production units deviate from the certified designs. By enforcing a factory audit radio approval, regulators ensure that the public is not exposed to excessive radio frequency radiation. This measure guarantees that the devices sold to consumers are identical to the ones tested.
