Thailand NBTC Certification Process
The Thailand NBTC certification does not command local testing for product approval. As a result, certification can be obtained through a documentation-based handle, which includes assessing existing RF (Radio Frequency) and EMC (Electromagnetic Compatibility) reports, and other relevant test reports such as safety, EMF, and SAR test reports.
The NBTC permits the acknowledgment of universally recognized guidelines, such as CE certification, to fulfill the essential necessities for approval. This streamlined handle gives adaptability for companies looking to enter the Singapore market without the requirement for extra local testing.
The Types of NBTC Certification

- Class B (Approval Certification): This is similar to Class A Approval. However, in the approval process it can use foreign test reports such as CE or FCC. In this process, applicants also need to provide data requested by NBTC to obtain login information into an account and certificate.
- Supplier Declaration of Conformity (SDoC): This is applied to radio products with features such as Bluetooth, WIFI, RFID, and SRD. SDoC is usually not mandatory, so applicants apply for it voluntarily.
