NBTC Certification Checker
Answer a few questions to identify the applicable NBTC certification type for your device.
Step 1 of 4
Does the device contain a radio transmitter?
Examples: Wi-Fi, Bluetooth, cellular, RFID, LoRa, or any other wireless module.
Not sure about your device?
Frequently asked questions
Check each frequency separately. Each radio technology in a multi-radio device is assessed under its own NBTC application. The most restrictive certification type across all technologies determines the overall certification class for the product.
This indicates a split-path application where transmit power is the deciding factor. The checker will ask for the maximum transmit power of your radio module. If the power is at or below the threshold, SDoC applies. Above the threshold, Class A (Registration) is required.
Several frequency bands are shared between multiple NBTC applications. The applicable certification depends on the wireless technology in your device, not the frequency alone. Selecting the correct technology ensures the result reflects the right NBTC application.
The checker provides a preliminary classification only. Before commissioning test reports, you should verify the applicable NBTC technical standard for your specific device type. Zergo's Pre-Submission Review covers this verification.
SDoC stands for Supplier's Declaration of Conformity — NBTC's formal designation for the self-declaration scheme. The manufacturer must still submit a complete application with valid test reports from an accredited laboratory outside Thailand.
