Within the regulatory framework of the chemical sector, the declaration of imported chemicals is designed as a pre-clearance control mechanism of a technical nature, aimed at ensuring transparency of chemical flows before they enter the territory of Vietnam.

This is not merely an administrative requirement, but also a tool for regulatory authorities to monitor risks related to safety, environmental impact, and compliance with specialized laws.

In terms of scope, the declaration obligation applies to chemicals falling under specific categories within the import–export commodity classification system, and must be completed prior to customs clearance via the National Single Window portal.

Notably, the declared data serves not only customs procedures but is also shared with specialized regulatory authorities, forming an integrated supervisory system.

Dossier for declaration of imported chemicals includes:

• Electronic declaration information on the organization/individual and the imported chemicals;
• Commercial invoice (with a certified Vietnamese translation if issued in a foreign language);
• Safety Data Sheet (SDS);
• For non-commercial cases: cargo arrival notice as a substitute for the commercial invoice.

Procedure for implementation:

• Create an account and log in to the National Single Window portal;
• Declare complete chemical information and upload the electronic dossier;
• The system automatically transmits data to specialized regulatory authorities;
• Receive legally valid electronic feedback for customs clearance;
• Post-clearance, data is updated and shared for regulatory purposes.

From a legal perspective, organizations and individuals bear full responsibility for the accuracy of the declared information.

Errors in the data may not only result in refusal of customs clearance but can also constitute grounds for administrative sanctions.

Accordingly, chemical declaration is not merely a technical step in the logistics chain, but a critical compliance checkpoint determining the legality of the entire import operation.
