越南海关10月切换JSON报文，电子单证翻译要跟上

Background Brief

Starting October 15, Vietnam Customs will unify electronic document data exchange between import/export enterprises and the customs system under the JSON message standard. The old format will lapse once it expires, and customs declaration software and logistics systems need to complete interface integration testing in advance—there is no transition period.

Translation-Related Points

• Field-level mapping: The customs declaration (t khai hải quan) becomes structured fields in the system. Vietnamese and Chinese field names must correspond exactly—one mismatch could lead to a rejected filing.
• Broker linkage: Data exchange between customs brokers (đại lý hải quan) and customs (hải quan) becomes more transparent. Translated documents serve as a manual verification step, and consistent terminology can directly lower inspection rates.
• Value of learning Vietnamese: Document-handling staff who know basic export (xuất khu) / import (nhập khẩu) vocabulary can locate abnormal fields in the messages more quickly.

Practical Tips

For translating electronic documents, the recommended approach is "field mapping table + system verification": build a standard glossary covering terms such as tờ khai hải quan, đại lý hải quan, and hải quan, and reference the same source for both entry and verification, to avoid spelling drift for the same term across different messages.
