If your product is an ordinary electronic product without any wireless functions, then this detailed explanation of FCC SDoC certification updated for 2025 is perfect for you. The table below summarizes the most core information.

FCC SDoC Certification for Non-Wireless Electronic Products:

Applicable Product Range    Electronic products without wireless functions, e.g., home appliances (microwave ovens, refrigerators), IT equipment (monitors, wired keyboards/mice), lamps (LED bulbs, ballasts), power adapters, etc.

Core Test Items Electromagnetic    Compatibility (EMC) tests, mainly including: Conducted Emissions, Radiated Emissions, Harmonic Currents.

Responsible Party & Labeling   • Responsible Party: Must be a US local company (manufacturer, importer, etc.).

                                  • FCC Mark: Has become voluntary to affix, no longer mandatory.

Process & Timeline           1. Prepare documents and send samples for testing.2. Laboratory testing.3. Sign the Supplier's Declaration of Conformity (SDoC).

                                  • Timeline: Usually 10-15 working days, may extend for complex situations.

Cost Composition           Testing costs are typically between ¥1,000 and ¥3,500 RMB.

  FCC SDoC Certification Process and Key Details:

If you are preparing to certify your product, understanding the following process and details will be more helpful:

Confirm Product Applicability:

This is the most critical first step. Be sure to confirm your product has no wireless transmission functions. If the product contains modules like Bluetooth or Wi-Fi, you need to apply for FCC ID certification.

Select Laboratory and Conduct Testing:

Testing needs to be conducted in a laboratory with appropriate qualifications. Although the laboratory does not need to be designated by the FCC, priority should be given to institutions compliant with the ISO 17025 standard to ensure the authority of the report. The main test item is Electromagnetic Compatibility (EMC), ensuring your device neither causes harmful interference to other devices nor has a certain level of anti-interference capability.

Sign Declaration and Retain Documents:

After passing the tests, the US Responsible Party needs to sign the Supplier's Declaration of Conformity (SDoC) document. Special attention is needed here: All technical documents (including test reports, circuit diagrams, SDoC, etc.) must be retained for at least 10 years after production of the product has ceased for potential FCC inspection.

  ⚠️ Important Reminders and New Regulation Interpretation:

In addition to the basic process, the following latest developments and potential risks require your special attention:

·Impact of 2025 Security New Rules: In August 2025, the FCC released new rules on the Equipment Authorization Security Program. Although this regulation primarily affects FCC ID certification and explicitly prohibits the use of test laboratories associated with prohibited entities, it also reminds us that choosing independent, compliant third-party laboratories is crucial for ensuring the long-term validity of certification.

Avoid Potential Risks:

·Do Not Make False Declarations: The FCC conducts market spot checks. If found providing false declarations or the product does not meet requirements, you will face risks of product removal from the market, high fines (up to $1.5 million), and loss of credit.

·Standards Are Not Universal: Even if the product has passed the EU's CE certification, it cannot directly replace FCC certification. EMC standards differ between Europe and the US, and specialized FCC testing for the US market is mandatory.
