For wireless and electronic products entering the US market, FCC authorisation follows two paths by device nature. Devices with intent to emit radio frequency (Wi-Fi, Bluetooth, cellular) go through Certification, where a TCB reviews and issues the FCC ID. Ordinary electronic appliances without intent to emit go through SDoC, a self-declaration by the company, but EMC testing is still mandatory. Which path applies depends on whether the device actively emits RF — do not guess by size or use. A multi-function product (a speaker with Wi-Fi) is governed by the stricter class. BlueAsia works on wireless certification and reminds companies to settle the path before preparing documents, avoiding the wrong test category.
2. Company Qualifications and Accounts
Two steps must be in place before application.
Accounts and Agent First
(1) Grantee Code. The company code applied for from the FCC; it is the first half of every FCC ID and stays permanently with the company. The first application pays a registration fee.
(2) FRN and TCB. Register an FRN in the FCC system, then select an accredited TCB to submit Form 731. Non-US companies must provide US local-responsible-party information — this step is mandatory. TCBs specialise in different product categories, so confirm coverage of your rule part before selecting.
① Lab qualification and agent information are the preconditions for TCB acceptance.
3. Test Reports Are the Core
Reports must come from an FCC-recognised lab accredited by A2LA or NVLAP, be fully in English, and show limits alongside measured values. RF testing measures power, frequency deviation, spurious emissions and frequency stability per the applicable rule part (Part 15, 22, etc.). EMC testing runs conducted and radiated emissions per ANSI C63.4 and C63.10 in an anechoic chamber. RF exposure applies to every intentional radiator; ultra-low-power devices may be exempt from SAR/MPE, handheld portables get physical SAR measurement, and fixed distant-mounted units get MPE calculation. Antenna gain and transmit power must align between the exposure assessment and the main RF report, or the submission is sent back.
4. Technical Design Documents
The TCB reviews engineering detail, so the documents must be complete. The block diagram shows every crystal, signal path, frequency and tuning range. The circuit schematic must be a full diagram for intentional radiators, and given per channel for multi-RF devices (Wi-Fi plus Bluetooth plus cellular). The operational description states function, protocol, band, modulation, peak power and antenna type — written for the reviewing engineer, not a consumer manual. PCB layout and BOM mark antenna routing, shielding and front-end component placement; the BOM lists exact part numbers that the TCB cross-checks against antenna, front-end and crystal.
5. User Documentation and Labels
The user manual must include the verbatim FCC Part 15 compliance statement; handheld devices add a body-separation-distance warning. The FCC ID label artwork and placement show the ID in the format "FCC ID: XXXX-XXXXXXX", permanently etched or on a nameplate, with a minimum font size and the single-line uppercase "FCC ID" prefix. For devices too small to display it, the ID goes in the manual or packaging. Non-standard labels stall issuance even when the technology passes.
6. Authorisation and Confidentiality Files
The power of attorney is signed by the legal representative, authorising the agent to submit Form 731 and the full package. A confidentiality-request letter can ask that sensitive documents stay temporarily or permanently undisclosed, with reasoning attached. Whether the submission is complete hinges on a pre-submission checklist; unanswered technical queries stall the review indefinitely. Missing signatures on confidentiality or authorisation files block acceptance outright.
7. Certificate Validity and Maintenance
The FCC ID itself has no fixed term and is long-term valid at the official level, but a substantive change to hardware, software, circuit or antenna that affects RF/EMC requires re-certification; when the FCC updates technical standards the company must stay compliant; a complaint-verified violation can lead to revocation and sales ban. Keep technical documents on file for at least five years for inspection. Connected-vehicle products eat this too — coordinate early and save the trouble.
