If your product is an electronic device without wireless functionality, you fall under the FCC SDoC (Supplier’s Declaration of Conformity) certification path.
This procedure ensures compliance with U.S. electromagnetic compatibility (EMC) regulations under FCC Part 15B. In 2025, several procedural and compliance updates were introduced — especially concerning laboratory independence and documentation retention.
| Certification Dimension | Core Content & 2025 Latest Requirements |
|---|---|
| Applicable Product Range | Non-wireless electronics, such as: • Home appliances (microwave ovens, refrigerators) • IT equipment (monitors, wired keyboards/mice) • Lighting products (LED bulbs, ballasts) • Power adapters, chargers |
| Core Test Items | Electromagnetic Compatibility (EMC) tests, including: • Conducted Emissions • Radiated Emissions • Harmonic Currents |
| Responsible Party & Labeling | • Responsible Party: Must be a U.S.-based company (manufacturer, importer, or distributor). • FCC Mark: Optional (no longer mandatory). |
| Process & Timeline | 1️⃣ Prepare documentation & samples 2️⃣ Conduct EMC testing 3️⃣ Sign SDoC declaration Timeline: ~10–15 business days (may extend for complex devices). |
| Typical Cost Range | Approx. ¥1,000–3,500 RMB (≈ $140–$500 USD) depending on product type and test complexity. |
Ensure your device does not include wireless transmission modules such as Wi-Fi, Bluetooth, or cellular chips.
If wireless functions exist, your product must apply for FCC ID Certification instead of SDoC.
Testing must be conducted in a competent, independent laboratory.
Prefer labs accredited under ISO/IEC 17025 to ensure report credibility.
Testing focuses on Electromagnetic Compatibility (EMC) — ensuring your product does not cause harmful interference and can withstand external interference.
Key Test Items:
Conducted Emission (Power line interference)
Radiated Emission (Electromagnetic radiation)
Harmonic / Flicker (Power quality consistency)
After successful testing:
The U.S. Responsible Party signs the Supplier’s Declaration of Conformity (SDoC).
Maintain all technical documentation — including test reports, circuit diagrams, and signed SDoC — for at least 10 years after production ends.
The FCC may request this documentation for random inspections or compliance verification.
In August 2025, the FCC implemented a new Equipment Authorization Security Program targeting all testing and certification bodies.
Although this rule primarily impacts wireless product certifications (FCC ID), it emphasizes the importance of choosing independent, secure, and compliant laboratories for SDoC testing.
| Security Rule Element | Key Point | Relevance to SDoC |
|---|---|---|
| Ownership & Control Review | Prohibits test labs linked to restricted foreign entities or governments. | Always verify your test lab is not on the FCC’s prohibited list. |
| Disclosure Requirements | Labs must file ownership information (≥5% equity disclosure). | Ensures independence and avoids invalid test reports. |
| Implementation Date | Effective September 8, 2025 | Affects all FCC-recognized labs, including EMC testing providers. |
Tip: Using a non-compliant or non-declared lab can invalidate your test results and delay U.S. market entry.
Submitting false or incomplete SDoC documentation can result in:
Market removal
FCC fines (up to $1.5 million)
Loss of importer or manufacturer credibility
Passing CE EMC tests does not automatically satisfy FCC requirements — the testing methods and frequency limits differ between Europe and the U.S.
Reports issued by non-accredited or restricted labs may be invalid. Always confirm lab accreditation and compliance with FCC 2025 security regulations.
✅ Use Accredited Labs:
Choose ISO 17025-accredited labs with a proven FCC SDoC testing track record.
✅ Bundle Global Certifications:
If you plan to sell in both the U.S. and Canada, your FCC Part 15B test report can be reused for ISED Canada ICES-003, saving cost and time.
✅ Maintain a Compliance Archive:
Keep a digital folder with test reports, SDoC, and technical files for quick access during audits.
✅ Stay Updated:
Regulations are periodically updated — always verify with your lab or consultant before each new product launch.

Q1: Do all electronic products need FCC certification?
→ Yes. All electronic products sold in the U.S. must meet FCC EMC requirements.
Q2: What is the difference between SDoC and FCC ID?
→ SDoC applies to non-wireless products; FCC ID applies to wireless or radio-transmitting products.
Q3: How long does the process take?
→ Typically 10–15 working days. Complex models may require more time.
Q4: Is it necessary to place an FCC logo on the product?
→ Optional — no longer mandatory under the current rules.
Q5: Can I reuse my CE test report for FCC?
→ No. CE and FCC use different frequency bands and limits. Separate testing is required.
