The FCC will cancel the DOC certification program and change it to the SDOC program.

By November of this year, the FCC's VOC failed, and the FCC's SDOC was enforced.
Interpretation of FCC SDOC:
The FCC SDOC has no certificates, only one statement and one report, and the report is not much different from the previous one.The content of the SDOC declaration is similar to that of EC declaration, including product information, application information, product compliance with U.S. regulations and standards, report number and so on.Most importantly, the declaration needs to include information about American companies, importers, agents, retailers, and so on.The information includes the name and address of the American company, the name of the person in charge and the handwritten signature, telephone, fax, email and so on.In a nutshell, the purpose of FCC SDOC is to find American companies responsible for the quality of products sold in the United States.When pushing the FCC SDOC to the customer, we must confirm with the customer that there is a native American company. Otherwise, we can't do SDOC, we can only make VOC. When the VOC fails, the customer is responsible for it.We report to the customer, plus a incomplete SDOC statement, lacks in the United States the information of the company, the customer to show it to the United States company fill, advises clients to deposit a statement in product packaging.
The above is my personal study and summary, you have different information, can be mentioned.Thank you!
