Vietnam Tightens Import Rules for Used Trucks from May 2026

Vietnam’s Ministry of Industry and Trade and Ministry of Natural Resources and Environment have jointly issued Circular 12/2026/TT-BCT, effective 1 May 2026, imposing new documentation requirements for imported used medium- and heavy-duty trucks (up to 8 years old). This regulation directly affects exporters, importers, logistics providers, and after-sales service operators engaged in the used commercial vehicle trade between China and Vietnam — particularly those handling second-hand trucks and chassis.

Event Overview

On 1 May 2026, Circular 12/2026/TT-BCT enters into force. Under the regulation, all imported used medium- and heavy-duty trucks aged eight years or less must be accompanied by: (1) an official emissions compliance certificate issued by the country of origin, confirming conformity with China VI or Euro VI standards; and (2) a complete 10-year maintenance and repair record, including documentation of major engine overhauls and Selective Catalytic Reduction (SCR) system replacements.

Industries Affected

Direct Trading Enterprises

Exporters and importers of used Chinese trucks and chassis face higher administrative and verification costs. The requirement for official, foreign-language emissions certification — which many original equipment manufacturers (OEMs) do not routinely issue for retired units — introduces delays and uncertainty in customs clearance. Verification of 10-year service history is especially challenging for vehicles previously operated by private fleets or unregistered operators.

Supply Chain & Logistics Service Providers

Firms offering pre-shipment inspection, document authentication, translation, and regulatory advisory services will see increased demand for specialized support on emissions compliance and long-term maintenance record validation. However, standard freight forwarders without technical documentation expertise may struggle to meet new verification expectations at Vietnamese ports.

After-Sales & Technical Support Providers

Service networks supporting imported used trucks — including spare parts distributors and certified repair workshops — must now prepare for heightened scrutiny of SCR system integrity and engine service history. Vietnamese authorities may cross-check submitted maintenance records against warranty databases or OEM service logs, raising operational accountability.

What Enterprises and Practitioners Should Monitor and Do Now

Track official implementation guidance

While Circular 12/2026/TT-BCT is published, detailed enforcement protocols — such as accepted formats for foreign emissions certificates, recognized third-party verification bodies, and criteria for ‘completeness’ of 10-year records — remain pending. Stakeholders should monitor updates from Vietnam’s General Department of Vietnam Customs and the Ministry of Transport.

Assess exposure by vehicle model and age cohort

Analysis shows that trucks manufactured between 2016–2018 — now entering the 8-year-old threshold — represent the most immediately affected segment. Exporters should prioritize verifying emissions certification availability for these models and identifying OEMs or authorized agents capable of issuing retroactive compliance statements.

Distinguish policy signal from operational reality

Observably, the 10-year maintenance record requirement exceeds typical fleet record retention periods in many markets. This suggests the rule may initially be applied selectively — e.g., focusing on high-volume importers or vehicles flagged during risk-based customs audits — rather than enforced uniformly across all entries.

Prepare documentation workflows in advance

Enterprises should begin aligning internal processes with the new requirements: standardizing bilingual maintenance log templates, engaging certified translators for official documents, and establishing direct channels with OEM service departments to request emissions attestations. Early coordination reduces bottlenecks ahead of the May 2026 deadline.

Editorial Perspective / Industry Observation

This measure is better understood as a regulatory signal than an immediate operational barrier. From an industry perspective, it reflects Vietnam’s broader shift toward tightening environmental controls on imported used vehicles — consistent with its National Green Growth Strategy and commitments under the ASEAN Agreement on Transboundary Haze Pollution. However, the feasibility of enforcing a full 10-year service history — especially for vehicles lacking centralized telematics or digital service tracking — remains uncertain. Current evidence suggests phased implementation is more likely than blanket enforcement from day one. Continued monitoring of customs circulars and port-level practice will be essential to gauge real-world impact.

In summary, Circular 12/2026/TT-BCT marks a formal escalation in Vietnam’s environmental gatekeeping for used commercial vehicles. It does not prohibit imports outright, but raises evidentiary and procedural thresholds significantly. For stakeholders, the current priority is not compliance panic, but structured preparation: mapping documentation gaps, clarifying OEM engagement pathways, and distinguishing between statutory requirements and practical enforcement patterns.

Implementation details — including acceptable formats for foreign emissions certificates and verification mechanisms for maintenance records — are still pending official clarification and warrant ongoing observation.
