Radio Frequency Testing

Bluetooth modules embedded in wireless products sold in China fall under SRRC (State Radio Regulation of China) type approval. This guide explains the process, documentation, cost and timeline factors, and cross-border marketplace compliance in plain language for international teams.GTG EMC Lab supports Bluetooth module makers with pre-testing and SRRC submission.

What is SRRC certification for Bluetooth modules

SRRC (State Radio Regulation of China) is China’s mandatory type approval for radio transmission equipment. Any Bluetooth module (classic or BLE) that emits radio frequency within China’s territory requires an SRRC certificate before it can be lawfully sold or integrated into finished products.

Applies to　Bluetooth BLE / BR / EDR modules used in IoT, wearables, and connected devices

Key basis　MIIT micro-power short-range radio equipment rules, e.g. MIIT Order No.129 [2021]

Bluetooth module SRRC certification process

1. 1Define RF parameters: confirm frequency band, transmit power, modulation, and antenna specification.
2. 2Pre-compliance testing: verify limits early to reduce the risk of failures at formal submission.
3. 3Sample testing: submit representative samples to a qualified laboratory for RF tests.
4. 4Prepare technical files: block diagrams, RF descriptions, and test reports.
5. 5Submission and approval: the authority reviews and issues the type approval certificate.

Documents you need to prepare

• SRRC application form and product technical description
• RF test report, circuit block diagram, and RF block diagram
• Antenna specification with gain and placement notes
• Representative samples
• Business license and power of attorney (if using an agent)

What drives the certification cost

SRRC cost is not a fixed number. It is shaped by RF complexity (single-mode BLE vs multi-mode Bluetooth plus Wi-Fi), the number of test items, whether pre-compliance is included, and agency support. GTG EMC wireless compliance service recommends sharing the module datasheet first so engineers can quote accurately.

What drives the timeline

The timeline depends on product type, test scope, sample readiness, and document completeness. Samples that pass on the first attempt and complete files move faster; supplementary testing extends the schedule. Plan ahead and keep buffer time before your launch window.

Cross-border marketplace and export risk

Inside China, Bluetooth modules need SRRC; for export, the target market sets the rules: the United States requires FCC, the EU requires CE-RED, Japan requires TELEC (MIC), and Korea requires KC. GTG EMC Lab advises aligning multi-country certifications during design to avoid射频参数 non-compliance at shipment.

Q1　Is SRRC mandatory for Bluetooth modules in China?

Yes. Any Bluetooth module sold or embedded in products within China’s market requires SRRC type approval because it is a radio transmitting device.

Q2　What is the difference between SRRC and FCC?

SRRC is China’s radio type approval for the domestic market; FCC is the United States compliance regime. They use different standards and authorities and cannot substitute for each other.

Q3　Does a Bluetooth module need CE-RED for Europe?

Finished products with Bluetooth exported to the EU generally need CE-RED covering radio and EMC. Module-level planning should consider the end-product use case.

Q4　How long is an SRRC certificate valid?

The certificate is tied to a specific model and its RF parameters. Any change to design or radio parameters usually requires re-evaluation per the latest authority rules.
