CTA Certification (China Type Approval) is a mandatory approval system for telecommunications and radio equipment products in China, enforced by the China Telecom Lab (TELECOM LAB) under the Ministry of Industry and Information Technology (MIIT) or authorized institutions. This certification ensures that communication equipment entering the Chinese market complies with national technical standards, cybersecurity, and interoperability requirements.

Key Points

1. Applicable Product Range

Telecommunications Terminal Equipment (such as mobile phones, tablets, smartwatches, etc.)

Radio transmitting equipment (such as Bluetooth devices, Wi-Fi modules, 5G devices)

Other networked devices (such as IoT terminals, vehicle communication modules)

2. Certification Process

Submit Application: Submit technical documents (product specifications, circuit diagrams, software information, etc.) to MIIT or authorized agencies.

Testing and Inspection: Conduct RF, safety, EMC, SAR, and other tests in the laboratory.

Technical Review: Verify if the equipment meets Chinese standards (e.g., YD/T, GB series).

Issuance of Certificate: Upon passing, receive the CTA Network Access License (marked with a green "Network Access Approval").

3. Key Requirements

Localization Support: The equipment must support Chinese frequency bands (such as NR/LTE/TD-SCDMA).

Data Security: Compliant with cybersecurity laws; certain equipment requires additional security assessment.

Label: Equipment must be marked with the network access permit number (e.g., 02 XXXX XXXXXX).

4. Relationship with Other Certifications

SRRC Certification: Radio Model Approval (for RF modules), usually conducted simultaneously with CTA.

CCC Certification: Some powered equipment may require an additional 3C certification.

5. Important Notes

Equipment without CTA certification may be detained by customs or prohibited from sale.

The certificate is typically valid for 3-5 years and requires renewal in advance.
