SDoC

Bluetooth Device NBTC Certification

Bluetooth devices sold or imported into Thailand require NBTC approval before they can be placed on the market. Bluetooth operates within the 2400–2500 MHz non-specific band, and all compliant devices follow the SDoC (Supplier's Declaration of Conformity) path — the most straightforward NBTC approval category, with an estimated processing time of approximately one week from submission.

Certification Requirements

Frequency Band	Max Transmit Power	Certification	Technical Standard
2400–2500 MHz	100 mW eirp	SDoC	Announcement regarding equipment permitted for general use

Bluetooth operates within the 2400–2483.5 MHz portion of the 2400–2500 MHz non-specific band. This band covers a wide range of short-range wireless technologies including Bluetooth, Bluetooth Low Energy (BLE), and Zigbee, all of which follow the same SDoC path under NBTC regulations.

Covered Device Types

Any product with Bluetooth or BLE connectivity falls under this certification path, regardless of primary function. Common examples include:

Wireless headsets, earbuds, and speakers
Bluetooth keyboards, mice, and game controllers
Smartwatches and fitness trackers
Smart home devices (locks, sensors, lighting controllers)
Medical wearables and patient monitoring devices
Industrial wireless sensors and asset tracking tags
Bluetooth modules embedded in larger products
