A Supplier's Declaration of Conformity (SDoC) is the FCC compliance mechanism by which the responsible party — typically the manufacturer, importer, or U.S.-based agent — self-certifies that an electronic product meets the applicable FCC technical standards. The SDoC replaced the older Declaration of Conformity (DoC) and Verification procedures under the FCC's 2017 modernization of 47 CFR Part 2 Subpart J.
The SDoC applies to most unintentional radiators (devices that generate RF energy as a byproduct, not intentionally), including computers, peripherals, LED lighting, and ordinary household electronics. Intentional radiators — Wi-Fi, Bluetooth, cellular, garage door openers — still require FCC Certification, the higher-rigor process involving a TCB (Telecommunication Certification Body) and an FCC ID.
An SDoC requires:
- Compliance information statement included with the product (in user manual or on the product)
- Identification of the responsible party — must be located in the United States
- Product identification (model number, name)
- A statement of compliance with the specific FCC rules
No SDoC is filed with the FCC. The responsible party retains the test records and produces them on demand.
A common compliance trap: importers assume "FCC compliant" means certified, but many products only require SDoC self-attestation. Conversely, intentional radiators must have an FCC ID — and Customs will detain products at entry if the label is missing.
For radiofrequency devices that previously required FCC Form 740, the FCC has largely eliminated that paper filing in favor of the electronic SDoC framework — though some legacy product categories may still require Form 740 documentation at entry.
