FCC stands for Federal Communications Commission, also known as the U.S. Federal Communications Commission. Established in 1934 by the Communications Act, it is an independent U.S. agency directly accountable to Congress. The FCC coordinates domestic and international communications by regulating radio broadcasting, television, telecommunications, satellites, and cables. It covers over 50 U.S. states, the District of Columbia, and territories to ensure the safety of radio and wire communication products related to life and property. The FCC Engineering Department is responsible for technical support for the committee and handles equipment recognition matters. Many radio application products, communication products, and digital products require FCC approval to enter the U.S. market.

FCC has two different certification methods for electronic products: FCC SDoC and FCC ID (Certification). The former is for products without wireless functions, while the latter is for those with wireless capabilities. Comparison and differences between FCC SDoC and FCC ID.

FCC SDoC and FCC ID applicable to products without wireless functions, such as displays and lighting, and products with wireless functions, such as cell phones and Bluetooth headphones. Test content includes electromagnetic compatibility (EMC), EMC + radio frequency (RF) certification, with low to high costs and short to long test cycle times.

　　FCC Standard Regulations

Here's the translation: The FCC Part 15 and Part 18 are widely applied: - FCC Part 15: Intentional Radiators Test - FCC Part 18: Industrial, Scientific, and Medical (ISM) Equipment - FCC Part 22: Public Mobile Telecommunications Services - FCC Part 24: Personal Communication Services - FCC Part 25: Satellite Communication Services - FCC Part 27: Other FCC Wireless Communication Services - FCC Part 68: Telecommunication Terminal Equipment FCC Part 15 specifies regulations for transmitting devices that are intentional, unintentional, or transient and do not require individual licenses to operate. This includes technical specifications, administrative requirements, and other market access conditions. Products are mainly categorized into four types: Unintentional Transmitters, Intentional Transmitters, Unlicensed Personal Communication Devices, and Unlicensed National Basic Information Equipment. FCC Part 18 regulates the electromagnetic energy emitted by industrial, scientific, and medical (ISM) equipment operating within certain frequency bands to avoid harmful interference to authorized wireless communication services.

　　Application Process

1. Customers submit the application form to the inspection agency.

2. Customers prepare the sample for testing (frequency-setting machines required for wireless products) and provide product information (refer to the information requirements).

3. Draft report issued by the testing agency, confirmed by the client, then a formal report is issued.

4. If it's a FCC sDoC, the project is complete; if it's applying for a FCC ID, submit the report and technical documents to the TCB.

5. TCB audit completed, issued FCC ID certificate; testing facility sends official report, FCC ID certificate.

6. Upon obtaining the FCC certification, the company may use the FCC logo and the relevant Statement on the product.

Note: Manufacturers applying for the first FCC ID certification must register with the FCC, establish a company file by creating an FCC-FRN, and upon completion of the TCB review, the issued certificate will contain an FCC ID number. Typically, the FCC ID is composed of "Manufacturer Code (Grantee code)" + "Product Code (Product code)."

Manufacturer Code: A three-digit number or uppercase letter, issued directly by the FCC.

Product Code: Composed of numbers, letters, and "-" symbols, but no two consecutive "-" symbols are allowed, and neither the first nor the last position can be a "-" symbol. The length of this code should not exceed 14 digits, and the customer can determine the number.
