FCC Certification from China: FCC ID & SDoC Guide (2026)

FCC ID vs SDoC: Which Path Does Your Product Need?

The single most important decision is whether your product is an intentional radiator (it deliberately transmits RF energy) or an unintentional radiator (it emits RF only as a byproduct of its digital circuitry, like a switching power supply).

If a product has both a transmitter and a non-transmitting function (e.g. a Bluetooth speaker), it needs FCC ID for the radio and must still meet Part 15B emissions — both are covered in the single FCC ID grant.

FCC Parts Reference Table

Knowing which Part applies prevents applying the wrong compliance path. Below are the Parts most relevant to consumer electronics sourced from China.

How to Get an FCC ID from China (Step by Step)

Yeatru walks electronics buyers through this sequence every month. Using an FCC-listed Chinese lab avoids flying samples to the US.

1. Classify the device — identify all radio technologies (Bluetooth 5.x, Wi-Fi 6, etc.) and confirm the applicable Part. If the device uses a pre-certified module, you may only need to reference the module's FCC ID (modular approval), cutting cost.
2. Engage an FCC-listed lab in China — BACL (Shenzhen), CMA, ITS, or SGS. Confirm the lab is listed on the FCC's Recognized Accredited Laboratories roster before paying.
3. Submit 2–3 engineering samples + technical dossier — schematic, BOM, block diagram, user manual, label artwork, and the external photos. The lab runs radiated/conducted emissions, SAR (for body-worn transmitters), and spectrum tests.
4. TCB reviews the test report — a Telecommunication Certification Body (e.g. UL, TUV, BACL itself as TCB) audits the report against FCC rules and grants the FCC ID (Grantee code + Product code) within 1–3 weeks.
5. Register & label — the grant is published in the FCC ID database. The FCC ID must be printed permanently on the product (or packaging if too small), with the Part 15 warning statement.

For SDoC products, steps 1–3 (lab test) apply, then the importer signs a Supplier's Declaration of Conformity listing the standards tested and naming a US responsible party. No TCB or FCC filing is involved.

Worked Example: FCC ID for a Shenzhen Bluetooth Speaker

A buyer sources a Bluetooth 5.3 portable speaker from a Shenzhen factory for Amazon US. The speaker has a Class 2 Bluetooth radio, a built-in 1500 mAh Li-ion battery, and a 5 W amplifier.

FCC Label Requirements

The FCC ID label is enforced at the port of entry. Rules:

• FCC ID number must be permanently affixed (silk-screen, etching, or durable label) — not a sticker that peels off.
• Minimum 6-point type, legible without magnification (except for very small devices).
• Part 15 warning statement: "This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation."
• SDoC-only products do not need an FCC ID but must be able to produce the DoC and test report within 14 days of an FCC request.

How Chinese Factories Fake FCC Certification

FCC fraud is common in the China electronics supply chain. Red flags:

• No test report — factory offers a "CE/FCC/RoHS" one-page certificate with no lab accreditation number and no test data.
• Copied FCC ID — the ID on the label belongs to a different manufacturer or a different model (verified in the FCC ID database).
• Wrong Part — a Bluetooth transmitter labeled only with Part 15B (unintentional) — this is illegal because the radio is uncertified.
• Module abuse — factory claims the Bluetooth module is pre-certified but modified the antenna or added a power amplifier, voiding the modular grant.

Always verify the FCC ID at fcc.gov/oet/ea/fccid, match the grantee name to your supplier, and request the original signed test report. Yeatru's pre-shipment QC includes FCC label verification as part of compliance checks.

How Yeatru Handles FCC Compliance

Yeatru Sourcing coordinates FCC testing and certification for US-bound electronics out of Shenzhen and Yiwu. Our compliance service includes:

• Product classification and path recommendation (FCC ID vs SDoC) — including whether a pre-certified module can be leveraged to save $1,000–$3,000
• Liaison with FCC-listed labs (BACL, CMA, ITS, SGS) for test scheduling and sample management
• TCB review coordination and FCC ID grant tracking in the OET database
• FCC label artwork review and on-product label verification during FBA prep
• Integration with electronics OEM projects so certification and tooling run in parallel

For the EU side, we bundle FCC with CE (RED) and RoHS to avoid testing the same hardware twice.

Frequently Asked Questions

1. What is the difference between FCC ID and SDoC?

FCC ID is the certification path for intentional radiators (Bluetooth, Wi-Fi, RF transmitters) and requires testing at an FCC-accredited lab, a TCB review, and a registered FCC ID number on the product. SDoC (Supplier's Declaration of Conformity) is the self-declaration path for unintentional radiators (power supplies, non-RF electronics); no FCC filing is needed, but you keep a test report and DoC on file and name a US responsible party.

2. Is FCC certification mandatory to sell electronics in the US?

Yes. Any electronic device sold or imported into the US that falls under FCC Part 15 (unintentional radiators) or Part 15C/15E (intentional radiators) must comply. Non-compliance leads to CBP detention, FCC fines up to $16,000 per violation per day, and market removal. Customs checks the FCC ID label and can request the test report.

3. Can I self-certify under FCC SDoC from China?

Yes, for unintentional radiators under Part 15 Subpart B. The supplier or US importer issues a Supplier's Declaration of Conformity based on a test report from an FCC-listed/ISO 17025 lab, keeps both on file, and names a US responsible party (US-based address) for correspondence. No filing or fee to the FCC is required.

4. How much does an FCC ID cost from China?

FCC ID certification runs $1,500–$8,000 depending on complexity: a simple Bluetooth module is $1,500–$3,000; a Wi-Fi router with multiple bands $3,000–$6,000; a complex 5G/SDR device $6,000–$8,000. Lab testing plus TCB review takes 4–8 weeks. SDoC testing only costs $300–$1,200 and takes 1–3 weeks.

5. How do I check if an FCC ID is real and valid?

Look up the ID on the FCC ID database at fcc.gov/oet/ea/fccid. The first 3–5 characters are the grantee code; the rest is the product code. Verify the grantee name matches the supplier, check the granted equipment authorization, and confirm the model number matches your product. A missing or mismatched record means the ID is fake.

6. How do Chinese factories fake FCC certification?

Common fakes: no actual lab test (just a printed certificate), an FCC ID copied from another manufacturer's product, the wrong Part applied (e.g. Part 15B label on a Bluetooth transmitter), or a grantee code that belongs to an unrelated company. Always verify the ID in the FCC database and ask for the original test report with the lab's accreditation number.

Conclusion

FCC compliance from China comes down to one fork in the road: FCC ID for intentional radiators ($1,500–$8,000, 4–8 weeks, TCB-reviewed) or SDoC for unintentional radiators ($300–$1,200, 1–3 weeks, self-declared). Getting the path right — and verifying the FCC ID in the FCC database — is what separates a shipment that clears CBP from one that gets detained and fined. Whether you're launching a Bluetooth speaker, a Wi-Fi sensor, or a simple USB charger, start the FCC process before mass production so the label and grant are ready when your first container ships.
