The FCC Supplier’s Declaration of Conformity (SDoC) is the essential compliance pathway for non-wireless electronic products entering the U.S. market. It ensures that your devices meet electromagnetic compatibility (EMC) requirements and can legally be sold in the United States.
As of late 2025, the FCC has introduced a new security regulation affecting all testing laboratories participating in its Equipment Authorization Program — a major shift that manufacturers must understand before choosing a lab.
The Federal Communications Commission (FCC) now requires all laboratories and certification bodies involved in the Equipment Authorization Program to undergo a security background review.
This policy aims to strengthen the integrity and safety of U.S. communication supply chains.
| Regulation Dimension | Core Content & Impact | Key Timeline |
|---|---|---|
| Prohibition Objective | Prevent foreign-controlled or high-risk entities from participating in U.S. equipment certification to protect national and supply-chain security. | Effective September 8, 2025 |
| Prohibited Entity Scope | Includes all companies listed on the FCC “Covered List,” U.S. Department of Commerce Entity List, or entities with ≥10% ownership/control by “foreign adversary” governments (e.g., China, Russia). | Labs required to submit no-affiliation declarations by October 6, 2025 |
| Ownership Disclosure | All FCC-recognized labs must disclose ownership of any entity holding ≥5% voting or equity rights. | Filing deadline: December 5, 2025 |
When selecting a test laboratory for FCC SDoC, you must:
Verify that the lab is not listed under any prohibited entity list.
Ensure the lab has submitted its ownership declaration to the FCC.
Failure to do so means your test reports may be rejected, blocking U.S. market entry.
The Supplier’s Declaration of Conformity (SDoC) applies to all non-wireless electronic products—devices that do not include intentional radio transmitters.
Household Appliances: Microwaves, refrigerators, washing machines
IT Equipment: Monitors, wired keyboards, wired printers
Lighting Products: LED bulbs, ballasts, power supplies
Adapters & Industrial Equipment: AC/DC converters, industrial controllers
SDoC focuses primarily on Electromagnetic Compatibility (EMC).
Main test items include:
Conducted Emissions (power line interference)
Radiated Emissions (electromagnetic radiation)
Harmonic & Flicker Testing (power quality compliance)
All testing follows FCC Part 15B standards.
Visual flow suggestion: Confirm Standards → Laboratory Testing → Declaration Signing → Documentation Retention → Market Compliance
Identify applicable FCC Part 15B clauses and product categories.
Send samples to a qualified FCC-recognized EMC laboratory for testing.
The U.S. Responsible Party (manufacturer, importer, or distributor) signs the SDoC form.
Keep all records — test reports, schematics, user manuals, and the signed SDoC — for 10 years after production stops.
Ensure continuous compliance; the FCC may audit or request verification at any time.
| Requirement | Deadline | Impact on Manufacturers |
|---|---|---|
| No-affiliation declaration | Oct 6, 2025 | Labs failing to file cannot issue valid FCC test reports |
| Ownership transparency report | Dec 5, 2025 | Ensures labs are not controlled by restricted foreign entities |
| Security compliance verification | Continuous (2026 onward) | FCC will revoke listings of non-compliant labs |
If your testing partner fails these steps, your product certification may become invalid.
Selling or importing non-certified products into the U.S. can result in:
Customs detention or rejection
Fines up to $16,000 per violation (per model or shipment)
Removal from major e-commerce platforms (e.g., Amazon, Walmart)
Civil or criminal liability for false SDoC declarations
Only partner with labs that:
Publicly state compliance with the FCC’s 2025 Equipment Authorization Program Security rule, and
Are not on the Covered List or Entity List.
If exporting to Canada, reuse FCC EMC reports for ISED Canada IC certification, minimizing retesting costs.
Maintain technical files digitally for at least 10 years and ensure the U.S. Responsible Party can be reached by the FCC.

Q1. Which products need FCC SDoC certification?
→ All non-wireless electronic devices such as IT equipment, home appliances, and LED lighting.
Q2. What is the biggest 2025 change?
→ The FCC now audits laboratories for ownership and foreign influence under the new “Equipment Authorization Program Security” rule.
Q3. Do wireless products use SDoC?
→ No. Wireless products must follow FCC Certification via a Telecommunication Certification Body (TCB).
Q4. How long does SDoC take?
→ Typical testing + documentation can be completed in 2–4 weeks for standard devices.
Q5. Can one test report cover both FCC and IC (Canada)?
→ Yes — in most EMC test setups, FCC Part 15B and ISED ICES-003 are harmonized.
