Supplier’s Declaration of Conformity (SDoC)
The Supplier’s Declaration of Conformity (SDoC) is a procedure under U.S. Federal Communications Commission (FCC) rules that allows manufacturers to self-declare that their equipment complies with applicable technical standards. It applies primarily to devices that may cause unintentional radiofrequency emissions.
Scope and Application
The SDoC process covers unintentional radiators, such as:
Personal computers and peripherals
LED lighting equipment
Industrial and consumer electronics without radio transmitters
Devices that combine unintentional and intentional emitters may require both SDoC and certification, depending on their configuration and components.
Regulatory basis: 47 CFR §2.906 and §2.1077
Requirements
Under the SDoC procedure, the responsible party—which must be located in the United States—is obligated to:
Ensure the equipment has been tested for compliance with FCC technical standards (testing by an accredited laboratory is not required, but the lab must meet FCC competence criteria under 47 CFR §2.948)
Prepare and supply a compliance information statement
Include either the FCC compliance statement in user documentation or optionally use the FCC logo (the logo is voluntary under SDoC)
Retain technical documentation, including test reports, for inspection by the FCC upon request
No third-party certification body (e.g., TCB) is involved in the SDoC process. However, all compliance evidence must be properly documented and made available to the FCC if requested.
