US FCC Certification

FCC stands for Federal Communications Commission. Established in 1934,

it is a government agency with law enforcement authority, mainly responsible for the administration and regulation of radio, communications and related fields. It cooperates with governments and enterprises to formulate FCC regulations and standards.

FCC certification is a mandatory EMC certification in the United States, mainly applicable to electrical and electronic products operating within the frequency range of 9 kHz to 3000 GHz. It covers various fields including radio and communications,

especially the radio interference issues of wireless communication equipment and systems, including radio interference limits, measurement methods, certification systems and organizational management regulations.

A wide variety of products are regulated by the FCC, including personal computers, CD players, copiers, radios, fax machines, video game consoles, office machinery,

electronic toys, televisions, microwave ovens and other products.

We can classify them into several categories, such as IT equipment, AV equipment, household appliances, communication equipment and low-power wireless transmitting products.

These products are divided into two categories, Class A and Class B, according to their application scenarios:

Class A: Products intended for commercial or industrial use;
Class B: Products intended for household use;

FCC imposes stricter regulatory requirements on Class B products with lower emission limits than Class A.

Three Types of FCC Certification Methods

1. Verification

Self-Verification: Manufacturers or importers shall ensure that their products undergo required testing to verify compliance with relevant technical standards and retain the test reports.

2. DOC (Declaration of Conformity)

Declaration of Conformity: The responsible party of the equipment (usually the manufacturer or importer) shall have the product tested by an FCC-designated accredited laboratory,

to ensure the equipment complies with relevant technical standards and keep the test reports. This is currently a widely adopted method covering a large range of products.

The issuing laboratory must be accredited under NVLAP (National Voluntary Laboratory Accreditation Program) or A2LA (American Association for Laboratory Accreditation).

3. Certification

FCC ID Certification: A TCB (Telecommunications Certification Body) reviews the samples (or photos) and test data submitted by the applicant. If the equipment meets FCC regulations,

an FCC ID number will be assigned to the equipment.

Applicable equipment includes low-power transmitters such as cordless telephones, automatic door remote controllers, radio-controlled toys, security alarm systems, etc.

Note: If one piece of equipment qualifies for two or three certification types, the responsible party may select the applicable scheme.

Test Items for FCC Wired Products

The FCC only regulates electromagnetic interference. Electromagnetic Interference (EMI) is mainly divided into the following categories:

1. Conducted Emission

Conducted interference propagates through power lines, signal cables and other conductors. The FCC specifies the frequency range from 150kHz to 30MHz. Most interference at low frequencies falls into conducted emission.

2. Radiated Emission

It propagates through free space. The FCC requirements apply to frequencies above 30MHz. Most high-frequency interference is radiated emission. The upper limit of test frequency is determined according to the highest frequency generated inside the product.

Generally, the two types of interference may exist simultaneously.

3. Terminal Disturbance (Antenna Port)

Mainly applicable to equipment equipped with external antennas, such as televisions.

FCC Certification Application Documents

1. Verification / DOC: Product User Manual, Application Form, Circuit Diagram

2. FCC ID (Main required documents as follows):

User Manual (Manual with required contents)
Test Report
Brief Description on Device Function
Block Diagram
Circuit Diagram
External Photos
Internal Photos
Form 731
Label

Service Process

Verification: Testing – Issue Test Report – Review – Obtain Documentation
DOC: Testing – Issue Test Report – Review – Obtain Documentation
Certification: If the applicant applies for FCC ID for the first time, apply for an FRN first to complete other forms, followed by an application for a permanent Grantee Code.
Meanwhile, the applicant may conduct product testing. Afterwards, all materials required by FCC, test reports and FCC Form 731 shall be submitted to the TCB for review, and the certificate will be issued finally.
