Does Bluetooth always require FCC Certification?

Yes, a product with Bluetooth must comply with FCC regulations. However, you can avoid full, standalone FCC certification if you use a pre-certified Bluetooth module.

The certification process depends on the design route you take:

• From-Scratch Design: If you build your own Bluetooth circuit board from the ground up, your product is classified as an “intentional radiator”. You will be legally required to undergo the full FCC Certification process with an authorized testing lab.
• Pre-Certified Module: Most manufacturers use a pre-certified Bluetooth chip or module. In this case, the radio part of your product has already been approved. You will only need to follow the Supplier’s Declaration of Conformity (SDoC) process for unintentional emissions and place an external label displaying the module’s FCC ID on your product.

Additionally, note that Federal Communications Commission (FCC) regulation is for US market access. It is entirely separate from Bluetooth SIG Qualification, which is the mandatory process required to legally use the Bluetooth logo and trademark on your device.
