ELECTRONIC CUSTOMS DECLARATION PROCESS FOR EXPORT SHIPMENTS
Overview of the customs declaration process and amendment/supplementary declaration procedures during customs clearance for export goods:

The customs declarant must submit export information through the EDA declaration function before registering an export customs declaration. After completing all required fields on the EDA screen (109 data fields), the declarant transmits the information to the VNACCS system.
The system will automatically assign a declaration number, generate information corresponding to the entered codes (e.g., importing country name corresponding to the country code, exporter name corresponding to the enterprise code), automatically calculate values related to customs value and duties/taxes, and return the information to the declarant via the Export Declaration Registration screen (EDC).
Once the system assigns a number, the Export Information Declaration (EDA) is stored in the VNACCS system.
Upon receiving the Export Declaration Registration screen (EDC) from the system, the customs declarant reviews both the declared information and the information automatically generated and calculated by the system.
If all information is confirmed to be accurate, the declarant submits it to the system for official declaration registration.
If any incorrect information is identified, the declarant must use the EDB function to recall the Export Information Declaration screen (EDA), amend the necessary information, and repeat the procedures described above.
Before allowing declaration registration, the system automatically checks the list of enterprises that are ineligible to register customs declarations (e.g., enterprises with tax debts overdue by more than 90 days, suspended operations, dissolution, or bankruptcy).
If an enterprise is included on this list, the declaration registration will be rejected, and the system will notify the customs declarant accordingly.
After registration, the system automatically assigns the declaration to one of three inspection channels:
Where no tax is payable:
The system automatically grants customs clearance (expected processing time: approximately 3 seconds) and issues a Goods Clearance Decision to the declarant.
Where tax is payable:
Payment by tax credit limit or guarantee (general or specific guarantee):
The system automatically verifies the declared credit limit or guarantee amount. If the available amount is equal to or greater than the tax payable, the system issues:
If the available amount is insufficient, the system generates an error notification.
Immediate tax payment (bank transfer, cash payment at customs office, etc.):
The system issues a Tax Collection Record. Once the tax, fees, and charges have been paid and VNACCS receives confirmation of payment, the system issues the Goods Clearance Decision.
At the end of each day, all Green Channel declarations are transferred to the VCIS system.
The declarant must:
The system will:
If no tax is payable:
If tax is payable:
Amendments or supplements may be made after declaration registration but before customs clearance.
To make an amendment:
After completing the amendment declaration (EDA01), the information is transmitted to VNACCS. The system assigns an amendment declaration number and returns the amended information via the EDE screen. The declarant then clicks "Submit" to complete the amendment registration process.
The amendment number is represented by the last digit of the declaration number.
Declarations that have been amended or supplemented can only be assigned to the Yellow Channel or Red Channel; they are not eligible for the Green Channel.
The data fields on the amendment screen (EDA01) are generally the same as those on the original export declaration screen (EDA), except for certain fields that cannot be modified or are not subject to amendment.
