If you export non‑wireless electrical products to the US, you cannot avoid FCC SDoC. With nearly 10 years in compliance, we help factories verify standards, manage lab tests, and pass Amazon and customs audits. This is the 2026 up‑to‑date guide.
FCC SDoC follows fixed FCC rules — no revisions in 2026.
1.FCC Part 15 Subpart BThe main standard for unintentional radiators — nearly all non‑wireless consumer and commercial electronics.
2.FCC Part 18For industrial, scientific, and medical (ISM) equipment (microwaves, ultrasonic devices, etc.) — rarely used in general e‑commerce.
3.ANSI C63.4The standard lab testing method, used automatically by qualified labs.
Note: Part 15A applies to wireless transmitters and is NOT used for SDoC.
II. Mandatory FCC SDoC Test Items
SDoC only covers EMC testing — no RF tests like FCC ID. All items are required.
1.Conducted EmissionsMeasures interference on power lines (150kHz–30MHz).Household products must meet Class B (stricter than industrial Class A).
2.Radiated EmissionsMeasures airborne interference (30MHz–1GHz).
Additional tests (harmonics, flicker) may be recommended but are not mandatory for SDoC.
III. 2026 Product Scope for FCC SDoC
Rule: Non‑wireless, powered products → SDoCWireless / RF transmitting → FCC ID
Typical SDoC products:
·Chargers, adapters, power banks, LED drivers
·Wired keyboards, mice, speakers, monitors, printers
·Lamps, fans, humidifiers, hair dryers, rice cookers
·Wired motors, power supplies, wired security power supplies
Products with wireless charging, Bluetooth, or remote control require FCC ID, not SDoC.
IV. 2026 Practical Compliance Tips
·Outdated or incomplete reports will be rejected by Amazon, Walmart, and customs.
·SDoC requires real test reports; fake or reused documents lead to delisting, seizure, and fines.
·Any circuit, component, or model change requires new testing.
FCC SDoC is based on FCC Part 15B and two EMC tests. Proper testing ensures US market access.
