Vietnam Tightens Heat Dissipation Import Rules With UL 1977

On June 28, 2026, Vietnam’s Ministry of Industry and Trade (MOIT) released Circular 12/2026/TT-BCT, setting a new compliance requirement for imported heat dissipation products. From October 1, 2026, imported heatsinks, including aluminum extrusions, heat pipe modules, and vapor chamber plates, must meet UL 1977 safety certification instead of the previous TCVN standard. This is worth close attention from exporters, manufacturers, importers, procurement teams, and supply chain service providers because the change directly affects product qualification, customs readiness, and delivery arrangements tied to the Vietnam market.

What the Circular Changes

According to the information provided, MOIT issued Circular 12/2026/TT-BCT on June 28, 2026. The circular states that, effective October 1, 2026, all imported heat dissipation products must obtain UL 1977 certification, replacing the earlier TCVN-based requirement. The scope specifically includes aluminum extrusion heatsinks, heat pipe modules, and vapor chamber products. The same information also indicates that Chinese heat dissipation exporters need to update their certification qualifications accordingly.

Where the Immediate Pressure May Appear

Export-facing manufacturers may face a certification transition issue

From an industry perspective, manufacturers supplying the Vietnam market may be affected first because product access will depend on whether the required certification status can be demonstrated. The pressure is likely to show up in product qualification files, shipment preparation, and coordination with downstream buyers on whether existing product lines remain eligible for import after the October 1 implementation date.

Importers and distributors will need to review inbound product readiness

Companies responsible for importing or distributing these products in Vietnam may be affected at the point where purchasing decisions and import arrangements rely on compliant technical documents. What deserves closer attention is whether incoming product categories fall within the stated scope and whether supporting certification materials are aligned with the new rule before goods move into the market.

Procurement and supply chain teams may need to reassess delivery planning

For procurement functions and supply chain service providers, the impact may center on delivery continuity. Analysis shows that any mismatch between product scope and certification status could affect ordering schedules, supplier confirmation, document checks, and shipment timing. Even without additional official detail in the provided material, the shift from one standard basis to another creates a practical need for earlier compliance verification in the transaction process.

What Companies Should Watch Next

Confirm which product lines fall under the stated scope

The provided information names aluminum extrusions, heat pipe modules, and vapor chamber plates. Companies serving Vietnam should review whether their exported or sourced products are sold under these categories and whether any related items may require the same treatment in practice once implementation begins.

Check whether certification documents are current and usable

The immediate operational issue is not only the existence of certification, but whether the certification status is aligned with the new import rule and can be used in actual trade documentation. For Chinese exporters in particular, the stated need to update certification qualifications suggests that document readiness should be treated as an active compliance task rather than a later administrative step.

Separate the policy signal from day-to-day execution risk

Observably, the circular provides a clear effective date, but day-to-day business risk will depend on how companies translate that requirement into purchase orders, shipment release processes, and customer communication. Businesses should pay attention to whether internal teams, trading partners, and service providers are working from the same understanding of the new standard basis.

Keep track of any follow-up wording or implementation clarification

What deserves closer attention is whether further official clarification appears around product scope, document form, or practical enforcement expectations. The core rule change is already stated in the provided information, but companies with active Vietnam exposure should continue monitoring for any follow-up interpretation that affects execution.

How This Should Be Read at This Stage

Analysis shows that this development is more than a routine wording update because it changes the standard framework tied to market entry for imported heat dissipation products in Vietnam. At the same time, it is more appropriate to understand this as a concrete compliance shift with immediate business implications rather than as a broad market conclusion. The clearest message today is that qualification requirements for affected imports are moving onto a new basis, and that makes certification alignment a near-term operational issue.

The Practical Meaning for the Market

At this stage, the most balanced reading is that Vietnam has introduced a defined compliance change for imported heat dissipation products, with a stated implementation date and a specified certification requirement. For the industry, the significance lies in trade execution, supplier qualification, and import readiness rather than in any confirmed market outcome beyond the rule itself. It is more appropriate to understand this as a near-term regulatory adjustment that may also serve as a longer-term signal worth continued observation.
