Today, most customs procedures are conducted through electronic platforms, including customs declaration submission, document authentication, and interactions with customs systems. These activities require a company’s digital signature to ensure legal validity and secure authentication. So, how can a business register its digital signature with customs authorities? In this article, VinaOpen provides a step-by-step guide on how to register and properly use a digital signature in compliance with customs regulations.
What Is a Customs Digital Signature?
A digital signature used in customs procedures is an electronic authentication method that verifies a company’s identity when conducting transactions on the electronic customs system.
A digital signature serves as an electronic authentication tool used by businesses for activities such as:
- Registering company information
- Submitting customs declarations
- Filing declaration amendments
- Sending electronic documents to customs authorities
According to Decree No. 08/2015/NĐ-CP, as amended and supplemented by Decree No. 59/2018/NĐ-CP, electronic customs procedures allow information to be transmitted, received, and processed through computer systems and networks instead of traditional paper documents.
As a result, digital signatures help ensure:
- Data authenticity
- Data integrity
- Legal validity of electronic documents
A digital signature is an electronic authentication method.
