Vietnam’s National Metrology Institute (VMI) implemented a new regulatory requirement on May 15, 2026, mandating that all imported biometric readers — specifically multimodal biometric readers — must be accompanied by a liveness anti-spoofing test report issued by a China National Accreditation Service for Conformity Assessment (CNAS)-accredited laboratory. The report must comply with GB/T 39579-2020 and bear a date later than January 1, 2026. This development directly affects exporters and importers in the biometric hardware supply chain, particularly Chinese manufacturers and logistics service providers handling Vietnam-bound shipments.

Event Overview

On May 15, 2026, the Vietnam Metrology Institute (VMI) formally enforced a new import requirement for biometric readers. Under this rule, all imported multimodal biometric readers must be accompanied by a liveness anti-spoofing test report verifying resistance to photo, video, and silicone mask attacks. The report must be issued by a laboratory accredited by China’s CNAS, conform to national standard GB/T 39579-2020, and carry a issuance date after January 1, 2026.

Impact on Specific Industry Segments

Direct Exporters (Chinese Manufacturers)
Manufacturers exporting biometric readers to Vietnam are now required to obtain and submit CNAS-issued liveness test reports as part of customs documentation. This adds a mandatory pre-shipment verification step not previously required under Vietnamese import procedures. Impact manifests primarily in extended lead times for documentation preparation, increased third-party testing costs, and heightened risk of customs delays — especially for small- and medium-sized enterprises lacking in-house compliance coordination capacity.

Supply Chain & Logistics Service Providers
Firms managing cross-border shipment documentation, customs brokerage, or freight forwarding for biometric hardware face revised document checklist requirements. Missing or outdated CNAS reports may trigger inspection holds or rejection at Vietnamese ports. The need to verify report validity (issuance date, accreditation scope, standard alignment) introduces an additional layer of due diligence into shipment release workflows.

Distributors & Channel Partners in Vietnam
Local distributors importing and reselling biometric readers must now validate upstream supplier documentation before goods arrive. Inability to confirm report compliance may delay inventory receipt, disrupt sales cycles, and increase working capital pressure due to storage or demurrage fees. Product portfolios with legacy stock lacking valid reports may require retesting or face market withdrawal risk.

What Relevant Enterprises or Practitioners Should Focus On and How to Respond

Verify current CNAS lab accreditation status and reporting scope

Confirm that the chosen CNAS-accredited laboratory explicitly lists GB/T 39579-2020 within its approved testing scope — not all CNAS labs cover this standard. Cross-check the lab’s CNAS certificate ID and validity period against the official CNAS public database before commissioning tests.

Align testing timelines with shipment schedules

Account for typical turnaround time (often 10–15 working days) for CNAS liveness testing and reporting. For shipments scheduled post-May 2026, ensure test reports are issued no earlier than January 1, 2026 — reports dated prior to that threshold will be rejected regardless of technical validity.

Update internal documentation checklists and training

Revise export documentation templates to include dedicated fields for CNAS report number, issue date, lab accreditation ID, and standard reference. Train export compliance staff and forwarders to flag reports failing any of the three criteria: non-CNAs issuance, absence of GB/T 39579-2020 reference, or pre-January 2026 date.

Maintain versioned records for parallel product SKUs

Where multiple firmware or hardware variants exist under one model number, confirm whether VMI requires individual reports per variant. Maintain clear version-controlled records linking each report to specific production batches and firmware versions to avoid ambiguity during customs review.

Editorial Perspective / Industry Observation

Observably, this requirement signals Vietnam’s shift toward harmonizing biometric device evaluation with internationally referenced technical benchmarks — specifically aligning with China’s domestic standard framework. Analysis shows it is less a standalone security mandate and more a procedural gatekeeping measure targeting documentation traceability and laboratory accountability. From an industry perspective, it functions primarily as a trade facilitation filter: valid reports streamline clearance, while gaps create friction — not necessarily reflecting device performance deficiencies. Current evidence suggests this is an operational signal rather than an indication of broader regulatory overhaul; however, its enforcement consistency and potential expansion to other ASEAN markets warrant ongoing monitoring.

Conclusion
This regulation marks a concrete escalation in documentary compliance for biometric hardware exports to Vietnam. Its significance lies not in introducing novel technical requirements, but in institutionalizing third-party validation — with CNAS accreditation serving as the de facto quality assurance proxy. For affected stakeholders, the change is best understood as a procedural tightening rather than a technical pivot. Preparedness hinges on disciplined documentation governance, not product redesign.
