Effective June 1, 2026, Vietnam will officially implement the mandatory VR-MARK certification system for imported industrial sensors. This policy has been formally confirmed for implementation by the Directorate for Standards, Metrology and Quality of Vietnam (STAMEQ), covering mainstream industrial sensor categories such as pressure, temperature, and displacement, directly affecting the sensor trade flow between China and Vietnam exceeding $1.2 billion annually, and creating systematic compliance pressure on distribution in Vietnam, customs clearance, end-use integration, and other links.

Event Overview

The Directorate for Standards, Metrology and Quality of Vietnam (STAMEQ) has officially confirmed that, starting from June 1, 2026, all industrial sensors imported into Vietnam (including pressure, temperature, and displacement types) must complete VR-MARK certification; the prerequisites for certification are: (1) appointing a local authorized representative registered with Vietnam’s business authority; (2) submitting a complete type test report issued by a laboratory recognized by STAMEQ. This requirement applies to new orders as well as signed but not yet shipped orders, with no transitional grace period.

Which market segments will be affected

Direct trading enterprises: mainly referring to Chinese manufacturers and foreign trade companies exporting sensors to end customers or distributors in Vietnam under FOB or CIF terms. Since VR-MARK certification cannot be directly applied for by overseas entities, companies must appoint a local Vietnamese entity as the legal responsible party, which requires restructuring the contracting party, liability allocation, and after-sales response mechanism; in addition, with type testing cycles generally reaching 6–10 weeks, the average order delivery cycle will be extended by 2.5 months, and the spot-sales model faces substantial risk of disruption.

Raw material procurement enterprises: including procurement service providers and integrated solution providers sourcing sensor modules for supporting local Vietnamese OEM/ODM manufacturers. Their procurement contracts are mostly signed based on the default clause of “certification exemption”; after the new regulation takes effect, if the original manufacturer cannot provide proof of VR-MARK compliance, it will constitute a delivery default; buyers will need to reassess supplier qualification lists and simultaneously initiate coordination with local representatives and testing schedules, resulting in a longer procurement decision chain and higher safety stock costs.

Processing and manufacturing enterprises: specifically referring to Chinese-invested and multinational manufacturers that have factories in Vietnam and use imported sensors to assemble industrial equipment (such as PLC control cabinets, smart instruments, and process control systems). Although they are engaged in local production, if the sensors used are imported and have not obtained VR-MARK, the complete equipment will not be able to pass Vietnam market access review; companies must trace the certification status of upstream components, forcing front-loaded compliance management across the supply chain, and some production lines may face the risk of temporary shutdowns.

Supply chain service enterprises: covering customs brokers, testing and certification agencies, VAT tax agents, and other third-party service organizations. The new regulation adds two mandatory documents to customs clearance paperwork: the Local Authorization Letter and the Declaration of Type Test Report Number and Issuing Institution. The absence of either one will trigger inspection and port detention; meanwhile, demand for derivative services such as qualification review of Vietnamese local representatives and cross-border verification of test reports will surge, making service capability and compliance response speed key competitive differentiators.

Key points of attention and response measures for relevant enterprises or practitioners

Immediately initiate the selection of local authorized representatives and agreement signing

Do not rely on existing Vietnamese distributors to automatically assume representative responsibilities——STAMEQ clearly requires that the representative must have independent legal entity status, be registered with Vietnam’s business authority for more than 1 year, and have no major record of quality-related violations. It is recommended to give priority to service organizations holding Vietnam import-export licenses and ISO/IEC 17065 certification qualifications, and simultaneously complete notarization of the authorization letter and filing with Vietnam’s commercial authorities.

Lock in STAMEQ-recognized laboratory resources in advance

At present, only 3 laboratories in Vietnam and 5 laboratories in China (including 2 institutions with dual CNAS+ILAC MRA recognition) have been publicly recognized by STAMEQ. Type testing items cover 12 core indicators including IP protection, EMC, environmental adaptability, and accuracy stability. It is recommended to submit products for testing in batches by product family to avoid scheduling delays caused by submitting all models at once.

Revise export contracts and technical agreement clauses

In newly signed and renewed contracts, it is necessary to clearly define the responsible party for VR-MARK, the party bearing certification costs, rectification obligations after test failure, and exemption conditions for delivery delays; the technical agreement should also supplement “type test report number” and “full name and registration number of the local representative” as required attachments for acceptance, in order to prevent customs clearance disputes.

Establish a dynamic ledger of sensor compliance status

For the application scenarios of the same model at different Vietnamese customers (such as explosion-proof vs ordinary industrial control), it is necessary to separately confirm the applicable standard versions (TCVN 8922:2025 vs TCVN 9278:2026), and record the validity period of each batch of reports and the change history of representative agencies, so as to support rapid response to customs inspections and market regulatory checks.

Editorial Viewpoint / Industry Observation

显然，这不仅仅是一次认证升级，而是越南工业产品治理向“本地责任”转型的结构性变化——将合规负担从产品符合性转向主体合法性。分析显示，目前超过73%的中国传感器出口商缺乏任何在越南注册的法律实体，这意味着到2026年第三季度，大多数企业将面临运营外包或退出市场。从行业角度看，要求提交认可实验室出具的测试报告——而不是自我声明或基于CE的等效认可——表明越南正在有意脱离与欧盟接轨的框架，并转向主权技术监管。更恰当的理解是，这体现的是监管成熟化的信号，而不仅仅是保护主义。

Conclusion

The implementation of VR-MARK certification marks that Vietnam’s market access for industrial products is moving from the stage of ‘formal compliance’ to that of ‘substantive accountability’. For China’s sensor industry, short-term pressure is unavoidable, but in the long run, forcing enterprises to improve the completeness of technical documentation, strengthen localized service response capabilities, and build cross-jurisdictional compliance coordination mechanisms is precisely the key leap path to breaking through barriers in the high-end industrial market of Southeast Asia. Rational judgment: rising compliance costs are a threshold, not the end point; enterprises that can complete representative binding and testing closed-loop processes first will gain a significant first-mover market share advantage in the second half of 2026.
