Vietnam Requires GB/T 19964-2026 for PV Module Imports

Vietnam’s Ministry of Industry and Trade (MOIT) has introduced a new import compliance requirement that took effect on July 10, 2026, drawing immediate attention from photovoltaic module exporters, importers, procurement teams, and project delivery participants. Based on the notice issued on July 7, 2026, imported solar modules entering Vietnam must now be accompanied by a conformity certificate issued by a CNAS-recognized laboratory in China under GB/T 19964-2026, while IEC 61215 on its own is no longer accepted as sufficient documentation. For the industry, the significance lies less in the wording alone and more in how quickly documentation expectations can change at the point of import.

What the New Vietnam Requirement States

The confirmed facts are clear. MOIT issued Notice No. 88/2026/TT-BCT on July 7, 2026. Under that notice, from July 10, 2026 onward, all imported photovoltaic modules must be submitted with a conformity certificate based on China’s latest national standard GB/T 19964-2026, titled Technical Requirements for Connecting Photovoltaic Power Stations to the Grid.

The requirement applies to imported photovoltaic modules including monocrystalline silicon products and bifacial modules. The certificate must be issued by a laboratory in China that is recognized by CNAS. The earlier practice under which IEC 61215 certification was accepted is no longer valid as a standalone basis.

Where the Immediate Pressure May Appear

Import transactions and customs-facing documentation

From an industry perspective, importers and direct trading companies are the first group likely to feel the impact because the rule is tied to accompanying documentation at the point of import. The practical pressure is likely to fall on document readiness, certificate matching, and whether shipment files can satisfy the new requirement without relying only on IEC 61215.

Module manufacturers serving the Vietnam market

Manufacturers that ship monocrystalline silicon or bifacial modules into Vietnam may be affected through product qualification workflows and pre-shipment preparation. Analysis shows that the issue is not simply product manufacturing, but whether the supporting compliance file is aligned with the specific standard and laboratory recognition requirement now referenced by the Vietnamese side.

Procurement and project delivery coordination

Procurement teams, EPC-related buyers, and delivery coordinators may need to pay closer attention to certification status before confirming supply arrangements. What deserves closer attention is whether procurement assumptions built around IEC 61215-only documentation remain usable for near-term deliveries into Vietnam after July 10, 2026.

Supply chain and compliance service providers

Service providers involved in documentation handling, trade compliance, shipment coordination, or supplier onboarding may also be affected. Their role becomes more sensitive where contracts, shipping schedules, or customer submissions depend on complete and acceptable technical certification paperwork.

What Companies Should Watch Now

Whether shipment documents are aligned with the new certificate requirement

Companies involved in exports to Vietnam should examine whether module shipments are supported by a conformity certificate issued by a CNAS-recognized laboratory in China under GB/T 19964-2026. This is a narrower and more specific requirement than simply holding an existing international product certificate.

How to handle products previously prepared under IEC 61215 alone

The summary provided indicates that IEC 61215 is no longer independently valid for this purpose. In practice, businesses should distinguish between documents that remain technically useful in other contexts and documents that are now insufficient for the stated Vietnam import requirement.

Supplier qualification and customer communication

For trading firms, procurement teams, and channel participants, supplier communication becomes a near-term operational issue. The immediate focus is likely to be on whether upstream suppliers can provide the required certificate, how quickly supporting files can be updated, and how this should be communicated to downstream buyers or project counterparties.

Further official clarification and implementation detail

Observably, the notice creates a clear document requirement, but companies should still continue tracking any further official language, implementation guidance, or clarification around application scope, document review practice, and treatment of shipments arranged around the effective date. That distinction matters for execution even when the headline rule itself is already stated.

Why This Looks Like More Than a Routine Document Update

Analysis shows that this development is best read as a compliance signal with direct commercial consequences, rather than as a purely formal standards reference. The key point is that Vietnam has linked import acceptance for photovoltaic modules to a specific Chinese national standard and to certificates from CNAS-recognized laboratories, while also making clear that IEC 61215 alone no longer closes the compliance gap.

It is more appropriate to understand this as an actionable short-term change with possible longer-term signaling value. The short-term element is obvious: documentation requirements changed with a defined effective date. The longer-term element still requires observation, especially regarding whether this remains a narrow import documentation measure or signals a broader preference for more specific grid-connection-oriented compliance references in this market.

How the Market May Need to Read This Update

At this stage, the most balanced reading is that the rule should be treated as an immediate operational compliance issue for photovoltaic module trade into Vietnam, while its broader policy meaning still deserves continued monitoring. The confirmed change is already concrete enough to affect certification planning, supplier readiness, and import documentation checks. Broader market impact, however, should not be overstated until further implementation detail or follow-on developments become available.
