Vietnam’s New Single Window Rules: Preparing Import and Export Workflows

Decree 336/2026/ND-CP takes effect on 15 October 2026, updating Vietnam’s National Single Window and ASEAN Single Window framework. Importers, exporters and logistics providers should check portal access, digital signatures, document formats and approval tracking, while confirming the implementation schedule for each procedure they use.

Vietnam will implement a revised framework for handling cross-border administrative procedures from 15 October 2026. Issued on 22 August, Decree 336/2026/ND-CP replaces Decree 85/2019/ND-CP and regulates procedures for exported, imported and transit goods, as well as transport entering, leaving or transiting Vietnam.

For businesses, the immediate priority is to ensure that shipment documentation, electronic submissions and approvals remain aligned as the framework takes effect. A filing error or an unresolved request for supplementary documents can affect production schedules, inventory availability and delivery commitments.

The effective date must be read alongside the decree’s implementation provisions. Individual procedure rollouts follow Ministry of Finance announcements, and certain ministry systems have a limited technical transition period. Businesses should therefore prepare for 15 October while checking the requirements applicable to their actual goods and filing routes.

What does the Single Window framework cover?

Vietnam’s National Single Window Portal connects declarants with customs and the authorities responsible for relevant administrative procedures. It receives electronic information, routes documents to ministry processing systems and returns processing status and results. Information is also exchanged with the customs electronic data-processing system and the National Public Service Portal.

Meanwhile, the ASEAN Single Window (ASW) links the National Single Windows of ASEAN member states to allow the secure, real-time electronic exchange of customs and trade documents.

Decree 336 applies to relevant public authorities, organisations and individuals involved in cross-border goods and transport procedures, as well as digital signature certification and software service providers.

For manufacturers and trading businesses, the practical task is to identify which licences, registrations, inspections or other administrative procedures apply to their shipments and which of those procedures are processed through the portal.

Effective from 15 October; check when each procedure goes live

The decree takes effect on 15 October 2026, but individual procedures will follow the rollout dates announced by the Ministry of Finance in coordination with the relevant ministries.

Ministry systems that cannot yet return results in the required format may continue using ministry-defined formats that meet Ministry of Finance data standards for up to one year while they upgrade.

This transition applies to government systems. Businesses must still meet their filing obligations and should check the applicable rollout date and submission format with the relevant authority or service provider.

Check account access and digital signatures

Users can register an account and digital signature on the National Single Window Portal, or use a VNeID electronic identification account to register and log in.

Businesses should keep account details and contact information up to date. If a broker or logistics provider handles filings, agree who prepares the information, signs and submits documents, and monitors responses from authorities.

Logging in through VNeID does not replace a required digital signature. Documents must carry the authorised person’s digital signature where the relevant procedure requires one.

Declarants must re-register the relevant information with the portal’s managing unit when registered details change, a digital certificate is renewed or its key pair changes. Foreign digital certificates must be licensed for use in Vietnam; a certificate issued overseas is not automatically accepted.

Check document formats before submitting

Declarations can be submitted using the common declaration data set, ministry-specific formats or direct entry on the portal. Changes and supplementary declarations must follow the relevant legal requirements.

Electronic documents must meet the format and legal requirements of the applicable procedure. Paper documents are still required where sector legislation requires them, or where system failures prevent electronic submission and exchange.

When converting a paper document into an electronic version, preserve its full content and apply the declarant’s digital signature registered with the portal. Uploading a scan alone may not meet the requirements.

Declarants must retain electronic and paper records as required by law and ensure that both versions are accurate and consistent.

Before filing, check that goods descriptions, quantities, units, origin, manufacturer details and supporting references match across shipment documents and regulatory submissions.

Track each filing through to clearance

The portal accepts electronic declarations 24/7 and automatically sends them to the relevant ministry systems. The responsible authority then confirms whether the application is accepted, rejected or needs changes and issues the processing result.

Processing deadlines remain governed by sector-specific legislation. The Single Window does not change the responsible authority, approval conditions, required documents or statutory processing periods.

A successful submission does not mean approval or customs clearance. Customs bases its clearance decision on the relevant authorities’ results transferred to the customs system.

Assign someone to track each pending application, respond to requests for additional documents and confirm that the required results are available for clearance.

Prepare for goods identification numbers

A goods identification number is an electronic code issued by the customs system to identify and track imported goods across customs and related regulatory procedures.

The rollout will follow the government’s customs implementing regulations. Businesses should check the applicable timeline; use will not necessarily begin for all imports on 15 October.

Keep references consistent across customs declarations and ministry applications so authorities can match records and businesses can avoid unnecessary follow-up.

Prepare a backup filing process

If a portal outage or force majeure prevents electronic information exchange, procedures may be completed using paper documents or ministry processing systems, following the responsible authority’s instructions and sector-specific rules.

The portal manager must announce which procedures can be handled outside the portal. Once service resumes, processing authorities must check, reconcile and transfer the data back to the portal.

Businesses should retain incident notices, proof of submission and authority instructions. Assign responsibility for contacting the authority, preparing alternative documents and confirming the application’s final status after service resumes.

Outlook

The commercial benefit of the revised framework will depend on how effectively businesses coordinate documentation, service providers and authority responses. Companies should use the period before commencement to resolve access and document issues, then continue monitoring procedure-specific announcements and system changes.
