On 2026年5月8日, Vietnam’s Ministry of Industry and Trade （MOIT） officially launched the ‘Vietnam Supplier Trust Index （VSTI）’ platform to implement automated credibility ratings for the official websites of Chinese export enterprises. This mechanism directly affects Chinese companies participating in Vietnam’s government e-procurement （e-GP） and VAT refund processes, and it constitutes a substantive technical compliance requirement especially for export industries such as electromechanical equipment, lighting fixtures, consumer electronics, building materials, and textile accessories that rely on official website display and data integration.

Event Overview

On 2026年5月8日, Vietnam’s Ministry of Industry and Trade launched the ‘Vietnam Supplier Trust Index （VSTI）’ system to conduct automated credibility scoring for the official websites of Chinese export enterprises. The scoring dimensions include: multilingual response time efficiency （required to be ＜3 seconds）, completeness of structured data on product pages （must comply with schema.org/Product specifications）, real-time inventory API availability, SSL certificate validity, and overseas IP access stability over the past 30 days. Enterprises scoring below 70 will be restricted from participating in bids on Vietnam’s government e-procurement platform （e-GP）, and their value-added tax （VAT） refund review progress will also be affected.

Which Sub-Sectors Will Be Affected

Direct Trading Enterprises

For foreign trade companies and cross-border e-commerce B2B sellers that connect directly with Vietnamese buyers through their own brands or independent official websites, the official website is the primary entry point for bid qualification review and credit assessment. The VSTI scoring result will directly trigger e-GP access restrictions, leading to the suspension of qualifications for shortlisted projects or the system interception of new bidding documents.

Processing and Manufacturing Enterprises （including OEM/ODM）

Although they may not participate in bidding directly, if they are designated suppliers for Vietnamese buyers, their official websites are often used as targets for supply chain due diligence; an excessively low score may cause buyers to question their digital capabilities and contract performance stability, indirectly affecting order allocation and long-term cooperation evaluations.

Channel Distribution Enterprises （importers, distributors, local agents）

Channel partners acting as bidding entities locally in Vietnam must submit the official website links of the Chinese manufacturers they represent to the e-GP platform for qualification verification. If the represented manufacturer’s VSTI score is below 70, the bidder’s own submission documents will be deemed incomplete, thereby affecting the overall validity of the bid.

Supply Chain Service Enterprises （including ERP, website development, SEO service providers）

For third-party organizations providing services such as official website construction, multilingual adaptation, structured data deployment, and API integration for export enterprises, their deliverables will be directly tested against VSTI technical indicators. Current service standards and acceptance criteria need to be updated in sync with the five mandatory VSTI requirements.

Key Points Relevant Enterprises or Practitioners Should Watch and How to Respond Now

Pay attention to the follow-up VSTI implementation rules and appeal channels released by Vietnam’s Ministry of Industry and Trade

At present, only the scoring dimensions and threshold have been clarified; the algorithm weighting, scope of test IP source locations, score update frequency, and enterprise self-statement mechanism have not yet been disclosed. Relevant enterprises need to continue monitoring updates on the MOIT official website and the Vietnam government procurement website （muasamcong.mpi.gov.vn）.

Prioritize technical compliance checks for official websites in high-value product categories

Focus on high-frequency procurement categories in Vietnam’s government e-procurement, such as LED lighting, low-voltage electrical appliances, water pumps, ceramic sanitary ware, and office furniture, and conduct dedicated testing on the official website pages of the corresponding product lines, with particular attention to verifying Schema markup completeness, multilingual switching response delay, inventory API return status, and SSL certificate validity period.

Differentiate between policy signals and the actual pace of business implementation

Based on current observations, VSTI may initially operate through pilot categories and pilot procurement entities rather than full-scale mandatory enforcement; however, since the scoring result has already been linked to e-GP bidding authority and VAT refund progress, this means technical compliance has shifted from a “recommended item” to an “access threshold” and can no longer be addressed later.

Start official website technical infrastructure upgrades and data interface preparation in advance

For official websites that still lack a real-time inventory API, have not deployed Product structured data, or experience timeout issues on multilingual page loading, it is recommended to carry out rectification item by item against the five VSTI indicators; avoid relying on generic website templates, and ensure stable overseas server access （it is recommended to use CDN services supporting Southeast Asia nodes and complete international compliance configurations beyond ICP filing）.

Editorial Viewpoint / Industry Observation

Analysis shows：VSTI is not an isolated technical evaluation tool, but rather a further institutional step by Vietnam to promote the digitalization of government procurement and strengthen the credibility of cross-border supply chain data. It is more like a scalable governance interface——currently focused on Chinese suppliers’ official websites, but with a technical framework compatible with extension to other exporting countries. Observably, what this mechanism is forcing is not merely single-page beautification, but a coordinated upgrade of enterprises’ front-end data service capabilities and back-end system connectivity. From an industry perspective, this marks that Southeast Asian market access is accelerating from the stage of “document compliance” into a new stage of “system verifiability and data traceability”; enterprises need to regard their official websites as key digital assets rather than promotional windows, as their technical performance now carries administrative effect.

Conclusion：
Vietnam’s activation of a credibility scoring system for Chinese suppliers’ official websites is essentially the incorporation of digital infrastructure capability into the cross-border trade credit system. It does not change existing trade rules, but it reconstructs the technical path of compliance enforcement. At present, it is more appropriate to understand it as: an access-oriented technical threshold that already carries binding force, rather than merely a rating initiative for reference purposes. Enterprises should treat it as a routine compliance item of equal importance to product certification and rules of origin, and include it in the foundational configuration checklist for export operations.
