Which department is responsible for inputting the certification information of imported goods? How to consult?

The certificate of imported goods should not be an official standard document. If it is a document to prove the import of goods, it is enough to have a customs declaration form or a customs tax document. If you want to go to a government department for verification, it is the customs. With court documents or lawyers' letters, you can inquire about the information of enterprises and individuals in many government departments.
