US FCC certification
Certification introduction
The full name of FCC is Federal Communications Commission, and Chinese is the Federal Communications Commission of the United States. Established in 1934 by COMMUNICATIONACT, it is an independent agency of the U.S. government and is directly responsible to Congress. The FCC coordinates domestic and international communications by controlling radio broadcasts, television, telecommunications, satellites and cables. Involving more than 50 states in the United States, Colombia and the United States, in order to ensure the safety of radio and wire communication products related to life and property, the FCC's Engineering and Technology Department is responsible for the technical support of the committee and is also responsible for equipment approval matters. Many radio application products, communication products and digital products require FCC approval to enter the US market.

FCC certification

Certification type
The US Federal Communications Commission (FCC) merged DoC and Verification into SDoC (Supplier's Declaration of Conformity) on November 2, 2017. SDoC certification will replace the FCC Verification and DoC certification procedures. All equipment applicable to the FCC Verification and DoC certification procedures will SDoC certification procedures can be adopted.

FCC divides the types of electronic products into two different certification methods: FCC SDoC and FCC ID (Certification). The former is suitable for ordinary products without wireless functions, and the latter is suitable for products with wireless functions.

FCC Common Standards
As follows, among which FCC PART 15 and PART 18 are the most widely used:

FCC standard scope of application

FCC PART15 C/E/F Intentional radiating device testing

FCC PART 18 Industrial, Scientific and Medical Equipment

FCC PART 22 Public Mobile Communications Services

FCC PART 24 Personal Communications Services

FCC PART 25 Satellite Communications Services

FCC PART 27 Other FCC Wireless Communications Services

FCC PART 68 Telecommunications Terminal Equipment

FCC Part 15 regulates intentional, unintentional or transient emission devices that do not require a personal license for use. It includes technical specifications, administrative requirements and other market access conditions. Products are mainly divided into four categories: unintentional transmitting equipment, intentional transmitting equipment, personal communication equipment that does not require a license, and basic information equipment in countries that do not require a license.

FCC Part 18 regulates the electromagnetic energy emitted by industrial, scientific and medical equipment (ISM) operating in certain frequency spectrum to avoid harmful interference to authorized wireless communication services.

application process
1. The customer submits the application form to the testing agency;
2. The customer prepares testing samples (wireless products require frequency fixing machine) and provides product information (see information requirements);
3. The testing agency issues a draft report, the customer confirms it, and issues a formal report;
4. If it is FCC sDoC, the project is completed; if it is applying for FCC ID, submit the report and technical information to TCB;
5. TCB will issue an FCC ID certificate after completing the review, and the testing agency will send a formal report and FCC ID certificate;
6. After an enterprise obtains FCC certification, it can use the FCC mark and related Statement on its products;

Note: Manufacturers applying for FCC ID certification for the first time need to register FCC-FRN with the FCC to establish an application company file. The certificate issued after the TCB review is completed will have an FCC ID number. Usually the FCC ID is composed of "Manufacturer Code (Grantee code)" + Composed of "Product code".
Manufacturer code: a three-digit number or capital letter, issued directly by the FCC;
Product code: It is composed of numbers, letters, and "-", but two or more consecutive "-"s cannot be used, and "-" cannot be used in the first and last digits. The maximum number of digits in this code does not exceed 14 digit, the number can be customized by the customer.
