From October 1, 2026, imported single-phase and three-phase smart electricity meters, including products with AMI modules, will face a new compliance step in Vietnam. Under a new MOIT circular issued on August 4, 2026, these products must complete local EMC immunity and EMI emission type testing at STAMEQ or an authorized laboratory and obtain a Vietnamese-language test report. For meter importers, manufacturers, and supply chain teams serving the Vietnam market, the issue is not only technical compliance but also the immediate effect on delivery planning, documentation, and lead times.

What the new requirement formally covers

According to the information provided, Vietnam’s Ministry of Industry and Trade issued Circular 18/2026/TT-BCT on August 4, 2026. The rule takes effect from October 1, 2026.

The requirement applies to all imported single-phase and three-phase smart electricity meters, including those equipped with AMI modules.

Under the new rule, the relevant products must undergo two local type tests in Vietnam: EMC immunity testing and EMI emission testing. The testing must be completed at the Vietnam National Institute of Metrology, known as STAMEQ, or at a laboratory authorized by it.

The products must also obtain a test report in Vietnamese.

The event summary further states that the new rule is expected to extend delivery cycles by 6 to 8 weeks, and that importers need to coordinate in advance with Chinese manufacturers to reserve testing slots.

Where the disruption is likely to appear first

Importers facing a longer pre-delivery path

From an industry perspective, importers are the first group likely to feel the operational impact because the new testing step sits directly in the market-entry process. The main pressure point is timing: if local EMC and EMI type testing must be completed before shipment or final delivery milestones, a 6 to 8 week extension can affect purchase planning, customs scheduling, and customer commitment dates.

What deserves closer attention is the testing reservation issue mentioned in the event summary. If testing capacity becomes a bottleneck, importers may need to decide earlier which meter models will be prioritized for the Vietnam market.

Chinese manufacturers under tighter coordination demands

Analysis shows that Chinese meter manufacturers supplying Vietnam may not be the regulated importer of record, but they are still directly affected. They may need to align product samples, technical files, and scheduling with importers so that local testing can be arranged without delaying contracts already in progress.

The practical impact is likely to appear in production planning and model allocation. Where several meter variants are sold into Vietnam, manufacturers and their customers may need to decide which configurations should enter the local test queue first.

Supply chain and compliance service teams managing document flow

Supply chain service providers and compliance support teams may also see a heavier workload because the rule explicitly requires a Vietnamese-language test report. Even without adding assumptions beyond the provided facts, this points to a documentation step that must be completed correctly for market access and handover processes.

For these teams, the main issue is not only obtaining the report, but also making sure the testing timeline and document readiness are aligned with shipment and customer delivery expectations.

Practical priorities for companies now

Confirm which products fall within scope

Companies should first check which imported smart meter models sold into Vietnam fall under the stated coverage, especially single-phase and three-phase smart electricity meters and products including AMI modules. The key practical question is whether existing sales pipelines contain affected models scheduled close to or after October 1, 2026.

Reserve laboratory timing early

Based on the event summary, one immediate concern is the 6 to 8 week lead time extension. For businesses with active orders, the most concrete operational response is to treat laboratory scheduling as part of delivery planning rather than as a final administrative step.

Prepare Vietnamese-language reporting requirements

The rule does not stop at testing itself; it also requires a Vietnamese-language test report. Companies should therefore pay attention to how test documentation will be obtained, reviewed, and matched with import documentation and customer-facing compliance files.

Separate policy text from execution risk

Observably, the formal rule and the real business impact are related but not identical. The confirmed fact is the local EMC and EMI testing requirement and the Vietnamese-language report requirement. The execution risk lies in how quickly labs can process applications and how efficiently importers and manufacturers coordinate the testing schedule. That distinction matters for planning.

Why this looks like more than a short-term paperwork change

Analysis shows that this development is better understood as an operational compliance shift rather than a minor document update. The requirement ties imported smart meter access to local testing completion in Vietnam, which means compliance timing becomes part of commercial timing.

At the same time, it is still too early to frame this as a broad market restructuring signal based only on the provided information. What is clearer at this stage is that companies serving Vietnam need to pay closer attention to testing lead time, report language requirements, and coordination between importer and manufacturer.

How the market is likely to read this move

It is more appropriate to understand this as a concrete near-term compliance change with possible longer-term implications that still need observation. In the short term, the clearest consequence is a longer delivery cycle for affected imported smart meters. In the medium term, the industry will likely watch whether local testing scheduling and document handling become recurring constraints in project execution.

For now, the most rational takeaway is straightforward: this is not just a regulatory headline, but a rule change that can alter delivery sequencing and contract planning for companies shipping smart electricity meters into Vietnam.
