Made a Bluetooth earphone or WiFi camera and want to list it on JD/Tmall? Hold on — every product with wireless transmission function must first obtain an SRRC type-approval certificate. Without SRRC, e-commerce platforms won't let you list, offline channels won't stock it, and if market supervision finds it, it gets delisted. This article explains every aspect of SRRC in the clearest terms.
What is SRRC? What does it govern?
SRRC stands for State Radio Regulation Committee, now handled by the Radio Administration under the Ministry of Industry and Information Technology (MIIT). In plain terms: if your product has any wireless transmission feature — Bluetooth, WiFi, 2.4G, 5G, NFC, LoRa, etc. — before selling on the Chinese mainland you must go to MIIT for "type approval" to verify your wireless transmission parameters, and once approved they give you a CMIIT ID.
This CMIIT ID must be printed on the product body or nameplate. It looks like this: YYYYDPXXXX (year + DP + number).
Which products must do SRRC?
Anything with radio transmission, including but not limited to:
- Bluetooth products: TWS earphones, Bluetooth speakers, Bluetooth keyboard/mouse, smart watches
- WiFi products: smart cameras, WiFi routers, smart-home gateways, AI glasses
- 2.4G proprietary protocols: wireless remotes, drone controllers, wireless microphones
- Cellular products: 4G/5G phones, CPE, MiFi, cellular modules
- Other wireless: NFC, RFID, LoRa, ZigBee, UWB, etc.
SRRC application process (4 steps)
Step 1: Prepare prototypes
2-3 prototypes, at least 1 must be a fixed-frequency unit (able to continuously transmit on a set frequency). A fixed-frequency unit is core to SRRC testing — without it, testing can't proceed.
Step 2: Lab testing
RF testing at an MIIT-recognised lab: transmit power, frequency range, occupied bandwidth, spurious emissions, frequency tolerance, etc. Takes about 2-3 weeks.
Step 3: Submit for approval
Once testing passes, the lab issues a test report, submitted together with the application form, company credentials and product documentation to MIIT for approval. Takes about 1-3 weeks.
Step 4: Get certified + label
Approval grants an SRRC certificate (valid 5 years) and assigns a CMIIT ID. Print the CMIIT ID on the product and you can sell it legally.
Common SRRC rejection reasons (pitfall-avoidance guide)
After 15 years in certification, the common SRRC rejections are just these:
| Rejection reason | Why | How to avoid |
|---|---|---|
| Spurious emissions exceed limits | Chinese limits on some bands are stricter than FCC/CE; directly citing FCC data often exceeds them | Do a pre-scan first, leave margin, adjust RF matching if over |
| Frequency range mismatch | Bluetooth in China can only use 2400-2483.5MHz; some overseas versions differ | Confirm the firmware locks the Chinese band range |
| Fixed-frequency prototype not ready | Without fixed-frequency firmware the lab can't test occupied bandwidth and spurious | Coordinate with the chip vendor/solution house in advance to prepare fixed-frequency firmware and tools |
| Non-compliant applicant entity | SRRC requires a mainland-registered company as the applicant | Overseas brands use a Chinese OEM or third-party agent to apply |
| Incomplete documentation | Circuit diagrams, PCB layout, antenna spec sheet, manual, etc. missing | Go through the checklist item by item, especially accurate antenna gain parameters |
SRRC vs FCC vs CE: key differences
Many people ask me: "I've passed FCC, do I still need SRRC testing?" The answer is yes. The differences:
| SRRC (China) | FCC ID (US) | CE-RED (EU) | |
|---|---|---|---|
| Standards system | Chinese standards | FCC Part 15C/E | ETSI EN 300 328, etc. |
| Test requirements | Some indicators stricter | Own system | Own system |
| Applicant entity | Chinese company | US agent + foreign company | Foreign company + EU rep |
| Certificate validity | 5 years | Long-term | Long-term |
| Mutual recognition | No | No | No |
When's the best time to do SRRC?
Late in R&D, before mass production. Too early — your RF parameters aren't finalised, you'd re-do it after testing. Too late — production is scheduled and waiting on the SRRC certificate delays your launch. My recommendation: start SRRC as soon as hardware is frozen, leaving room to sequence CCC and other certifications.
