Documents and Validity Period for FCC SDoC Certification of Non-Wireless Electronic Products

2025-10-17

For electronic products without wireless functions, FCC SDoC (Supplier's Declaration of Conformity) is one of the key compliance certifications for entering the US market. Below, I outline the required documents, the core interpretation of the validity period, and a latest regulation directly affecting the certification process as of October 2025.

List of Documents Required for FCC SDoC Certification:

Document Category	Core Content & Description
Product Technical Documents	Circuit Schematics, Block Diagrams Product Manual (Must include FCC compliance statement and warning) List of Critical Components
Testing-Related Documents	Complete Test Report:Issued by a qualified laboratory, covering all necessary EMC test items、. Laboratory Qualification Proof:e.g., ISO/IEC 17025 accreditation certificate.
Compliance Declaration Documents	Signed SDoC Declaration Document: Must be signed by the US Responsible Party (manufacturer, importer, or authorized representative). The declaration should include product model, FCC warning, and complete contact information of the US Responsible Party.
Product Identification Documents	Product Exterior and Interior Photos: Must clearly show the structure. Label Diagram: FCC SDoC certification no longer mandates affixing the FCC Logo on the product, but it is recommended to include the compliance statement text in the manual or on the device.

Detailed Explanation of FCC SDoC Certification "Validity Period":

This is a very crucial concept: FCC SDoC certification itself has no fixed validity period.

However, this "permanent validity" has strict conditions. The certification may become invalid under the following circumstances:

1.Product Design Changes:If the product's hardware, circuit structure, etc., undergo substantial modifications** that may affect Electromagnetic Compatibility (EMC), re-evaluation or certification is required.

2.FCC Technical Standard Updates:The FCC updates its technical regulations. Manufacturers are responsible for ensuring their products continuously comply with the latest standards; otherwise, the certification may become invalid.

3.Failure to Pass Market Surveillance: The FCC conducts market spot checks. If the product is found not to meet requirements or a false declaration is provided, the certification will become invalid, and you may face fines, product removal from the market, and other risks.

Important Obligation: Regardless of changes, according to FCC regulations, all technical documents (including test reports and the Declaration of Conformity) must be retained for at least 10 years after production of the product has ceased for potential FCC inspection at any time.

FCC SDoC Certification Process and Suggestions:

1.Confirm product applicability: Ensure the product has no wireless functions.

2.Choose a compliant laboratory and test: Send samples to a laboratory meeting the new rule requirements for EMC testing.

3.Sign declaration and retain documents: The US Responsible Party signs the Declaration of Conformity and organizes the complete technical file.

We hope this document list and latest interpretation of FCC SDoC certification helps you complete the certification efficiently.
