FCC Certification for Electronics from China
9 resources tagged with "Fcc"
Any electronic device with a clock or a radio sold in the US needs FCC authorization — either Part 15 SDoC (self-declaration) for unintentional radiators or full TCB certification for intentional radiators like BLE, WiFi, and LoRa. The key advantage for buyers sourcing from China is modular approval: ESP32 and nRF52 modules already carry an FCC ID, so building on them can avoid a full re-test, though the host device still needs verification. Lab testing for an intentional radiator typically runs $3,000-8,000 and several weeks.
The recurring mistake is assuming a module's FCC ID covers the finished product — it covers the module under its specific antenna and integration conditions. We confirm whether the design qualifies for modular approval, whether antenna and placement match the grant, and that the FCC ID is registered to a real grantee in the public database.

FAQ
Do I need full FCC certification or just an SDoC?
An unintentional radiator (no radio) usually qualifies for Part 15 SDoC self-declaration. A device with BLE, WiFi, cellular, or any transmitter needs full certification through a TCB and an accredited lab. Mixing the two up is a common compliance failure.
Can I reuse an ESP32 module's FCC ID for my product?
Often yes — modular approval lets a pre-certified ESP32 or nRF52 module carry its FCC ID into your host, provided you follow the module's integration rules (antenna type, gain, placement). The host still needs unintentional-radiator verification, but you avoid re-testing the radio.
How much does FCC testing cost and how long does it take?
An intentional radiator typically runs $3,000-8,000 and three to six weeks at an accredited lab. SDoC for a simple unintentional radiator is cheaper. Costs rise if the device fails emissions and needs a board respin and retest.
