Starting June 18, 2026, Vietnam’s national standardization body (TCVN) will implement a clear change to the inspection requirements for imported weighing sensors and displacement sensors: related products must complete full EMC immunity re-testing at designated laboratories in Hanoi or Ho Chi Minh City, and the original China CNAS reports will no longer be directly accepted. For exporters, buyers, inspection and testing coordination parties, and delivery arrangement personnel targeting the Vietnamese market, this is not only an adjustment to the inspection route, but also a perceptible change in customs clearance timeliness and compliance costs. It is therefore worth close attention from relevant industry-chain stakeholders.

The specifics of this rule adjustment are now clear

According to the information provided, TCVN announced that from June 18, 2026, all imported weighing sensors and displacement sensors must complete full EMC immunity re-testing at designated laboratories in Hanoi or Ho Chi Minh City, and the testing basis involves IEC 61326-1 Ed.3 Annex A. At the same time, the original China CNAS reports will no longer be directly accepted. The disclosed direct impact is that this policy will extend customs clearance by 7 to 10 working days and increase testing costs by 35%.

Changes are first transmitted to delivery and compliance coordination links

Export business targeting the Vietnamese market needs to reorder the testing sequence

For enterprises that directly export weighing sensors and displacement sensors to Vietnam, the impact is first reflected in pre-shipment and post-shipment compliance coordination. Since existing CNAS reports can no longer be directly accepted, the export, customs declaration, and customer delivery schedule originally arranged around Chinese local test reports must now reintroduce Vietnam local re-testing as a prerequisite. What enterprises need to pay close attention to is whether the technical data, test reports, and delivery commitments can still remain consistent, so as to avoid compressing the actual fulfillment period due to re-testing arrangements.

Procurement and project execution teams must reassess the lead time to delivery

For procurement parties and project execution units, the extension of the customs clearance cycle by 7 to 10 working days is a more direct impact. Especially in business scenarios where equipment installation, system integration, or spare-part replenishment depend on the on-time delivery of sensors, procurement plans, delivery milestones, and internal acceptance schedules may all be affected. From an analytical perspective, what currently deserves more attention is whether procurement documents, delivery terms, and acceptance time need to reserve a time window consumed by local re-testing.

The coordination requirements for inspection cooperation and supply chain services have increased

For supply chain service links that handle customs declaration, submission for inspection, and delivery coordination, this change increases the complexity of process organization. Because re-testing must be completed at designated laboratories, related business is no longer just about transportation and customs declaration arrangements, but extends to test booking, document coordination, and result handoff. From an observer’s perspective, in subsequent actual implementation, enterprises will pay more attention to whether customs declaration preparations are complete, whether the test arrangement is smooth, and whether there are matching issues between re-test results and existing technical documents.

What practical changes should be closely monitored at this stage

First check whether the product falls within the scope of this re-testing

Enterprises should first review whether their own exported or purchased products fall within the scope of the weighing sensors and displacement sensors explicitly mentioned this time, and adjust compliance preparation accordingly. If a business has long relied on existing CNAS reports as the basis for external communication, it should now promptly switch to preparing subsequent documents and delivery explanations around Vietnam’s local re-testing requirements.

Simultaneously review reports, technical documents, and commercial commitments

Since the original China CNAS reports will no longer be directly accepted, enterprises need to re-examine whether the current test reports, specifications, customs declaration materials, and related statements in contracts are still applicable. The focus of this step is not to duplicate all documents, but to confirm which materials will be used for local re-testing and which commercial commitments need to be updated due to changes in the testing cycle.

Incorporate the 7 to 10 working day extension into production and delivery communication

The disclosed customs clearance extension means that the schedule between suppliers and customers needs to move forward. For orders already in execution, enterprises should focus on delivery milestones, stocking schedules, and after-sales replacement arrangements to avoid planning based on the old cycle. For new projects or new inquiries, the change in timeliness may also affect quotations, delivery explanations, and procurement decisions.

Continue to pay attention to whether the execution path will be further refined

What is currently clear is the local EMC immunity full re-testing requirement, the designated laboratory locations, and the fact that CNAS reports are no longer directly accepted, but no more detailed implementation instructions have been provided. Therefore, enterprises still need to keep tracking whether more specific certification pathways, single-document requirements, or business handoff arrangements will appear later, and update internal processes accordingly.

This is more like a signal of execution tightening than a conceptual change

From an industry perspective, this news is more appropriately understood as a compliance requirement change that has already entered the execution level, rather than merely a directional discussion. Its core signal is that for related imported sensor products, Vietnam’s reliance on local re-testing has increased significantly, and the direct acceptance boundary for overseas reports has tightened. However, in terms of actual operating details, execution pathways under different business scenarios, and how the market adapts internal processes, continued tracking is still necessary.

This article is generated based on the title of the information provided by the user, the event time, and the event summary. Such events can usually be further verified by combining official announcements, information released by regulatory authorities, customs or trade主管部门, industry association information, standard organization documents, and reports from authoritative media. It should be noted that no specific official source link was provided in the input, so the original release documents and formal statements still require continuous verification. What is worth continued attention later includes: whether policy details are further clarified, whether the certification execution path is refined, whether bidding and procurement documents are adjusted accordingly, whether industry feedback becomes differentiated, and the delivery and compliance adaptation of enterprises in actual execution.
