Edi is a new business that exchanges data of trade, production, transportation, insurance, finance and customs documents between relevant departments or companies according to the standard format by e-mail, and processes messages according to internationally unified grammatical rules.

The two sides use a unified international standard format to compile documents and materials, and electronically transmit trade materials from one side to the other. This is a "paperless trade" method widely adopted by developed countries, and it is also a standard trade method that GATT member countries must use and promote in the future.
EDI (Electronic Data Interchange) is a computer application technology. Trading partners who apply this technology format economic information according to a certain standard according to the agreement reached in advance, and exchange and automatically process these data between their computer application systems through computer networks.

The application of EDI in customs business, namely "paperless customs declaration", simply means that customs declaration can be carried out without paper documents. Specifically, the customs declaration unit fills in the import and export customs declaration documents on the electronic computer terminal or microcomputer, and electronically transmits the customs declaration documents to the customs declaration automation system to declare to the customs; After the customs electronic computer examines and processes the customs declaration form, it will automatically issue a customs release instruction or issue a customs release notice (OK form) if it meets the customs supervision regulations. This way of customs declaration is called "computer customs declaration" or "automatic customs declaration" because it is carried out by computer from beginning to end without manual intervention. Because of the cancellation of traditional paper documents and bills, the declaration to the customs is electronic. Therefore, it is often called "paperless customs declaration". Obviously, the benefits of paperless customs declaration are: for customs declaration units, it can greatly save time, reduce costs, overcome the travel fatigue and waiting in line caused by on-site customs declaration, thus improving work efficiency; For customs, it can give customs officers enough time to process import and export declaration documents, reduce work mistakes and improve work efficiency.
