On July 15, 2026, Vietnam’s Ministry of Industry and Trade issued new regulations related to the import of photovoltaic cleaning equipment, clearly stating that starting from October 1, 2026, when declaring imports, the manufacturer’s ISO 50001 Energy Management System certificate issued in the country of origin must be submitted simultaneously, and the certificate must provide both Chinese and English versions. In addition, the issuing institution must be included in Vietnam’s recognized white list. For Chinese manufacturers, exporters, purchasers, and the customs clearance and delivery process targeting the Vietnamese market, this change is worth attention because it extends the originally product-oriented import process to the manufacturer qualification and certificate compliance level.

This change centers on import documents and certification conditions

The confirmed information shows that Vietnam’s Ministry of Industry and Trade (MOIT) issued Circular No. 12/2026/TT-BCT on July 15, 2026. According to the document, starting from October 1, 2026, all imported photovoltaic cleaning equipment must, together with the customs declaration, submit the manufacturer’s ISO 50001 Energy Management System certificate issued in the country of origin.

The certificate must be in both Chinese and English versions. At the same time, the issuing institution must be on Vietnam’s approved white list. The event summary shows that this measure is intended to strengthen energy efficiency supervision of imported equipment and will affect the access efficiency of Chinese manufacturers exporting to Vietnam.

From manufacturing to customs clearance, the affected links are shifting forward

For exporters and manufacturers, the impact is first reflected in qualification preparation

Analysis shows that this requirement directly applies to the manufacturer itself, rather than only to product sales contracts or routine customs documents. For Chinese manufacturers exporting photovoltaic cleaning equipment to Vietnam, whether they hold the required ISO 50001 certificate, whether the certificate has Chinese and English versions, and whether the issuing institution is on Vietnam’s approved white list may all become preconditions for smooth customs declaration. The key point to note is that this has already extended from simple delivery capability to the availability and matchability of manufacturers’ certification qualifications.

For trade and procurement links, certificate review may intervene earlier

From an industry perspective, exporters, importers, and purchasers may need to verify the status of the manufacturer’s certificate earlier when placing orders, signing contracts, and before production scheduling. The reason is that the new rules bind certificate requirements to customs declaration submission; if verification is not completed in the early stage, issues often emerge only close to shipment or during customs clearance. In actual business, what deserves more attention is whether procurement terms, supplier access review, and qualification document requirements in contract annexes may therefore be adjusted in sync.

For supply chain and delivery service links, operational pressure will increase

Observation shows that customs declaration services, logistics coordination, and delivery arrangements will also be affected. Because the new rules clearly define the certificate version and the scope of issuing institutions, supply chain service providers may need to add completeness checks for certification documents when receiving orders and transferring materials. For projects sensitive to delivery time, whether the certificate is fully prepared may directly affect shipping and customs clearance efficiency.

For certification and supporting service links, the importance of compliance verification increases

This change will also be transmitted to service links related to certification documents. Analysis shows that around the validity of ISO 50001 certificates, preparation of bilingual versions, and whether the issuing institution meets Vietnam’s recognition conditions, the verification work may become a key focus in internal corporate compliance reviews or external service support. The core here is not to add a new product standard, but that import compliance requirements have put forward more explicit adaptation requirements for certification documents.

What enterprises should focus on right now

First confirm whether existing certificates meet Vietnam’s import requirements

For relevant enterprises, the first step is to verify whether the existing ISO 50001 certificate was issued by the manufacturer’s country of origin, whether it has Chinese and English versions, and whether the issuing institution is on Vietnam’s approved white list. The input information does not provide the white list details or verification path, so at present it is more appropriate to understand this step as a compliance review focus rather than as an already unified enforcement result.

Move certificate preparation forward to before order placement and shipment

Because the certificate requirement is directly linked to customs declaration submission, enterprises should synchronously check whether related certification materials are complete when receiving orders, arranging production, and confirming shipment plans. Observation shows that if materials are still supplemented at the last minute under the traditional rhythm, the risk of delivery schedules being affected may increase. For businesses relying on fixed shipping windows, this point especially needs to be planned in advance.

Pay attention to whether procurement documents and supplier qualification clauses are adjusted

For buyers and channel parties, attention should be paid to whether subsequent procurement documents, technical documents, supply terms, or supplier access clauses will make the requirements for ISO 50001 certificates and issuing institutions more explicit. The input information has not yet provided tender documents or changes at the procurement rule level, so this is still a direction for later observation, but its impact on actual transaction and delivery arrangements deserves early attention.

Keep following the implementation path rather than just the document title

Analysis shows that what the current market needs to pay attention to is not only the fact that Circular No. 12/2026/TT-BCT has been issued, but also the specific implementation paths for certificate format, language version, issuing institution recognition, and material submission methods during subsequent execution. Since the input does not provide more detailed implementation instructions, enterprises still need to keep tracking at the operational level and avoid judging compliance boundaries based solely on the title.

This looks more like a clear implementation signal

As an observation, this information is more suitable to be understood as an essential requirement for import compliance toward manufacturers, rather than a mere policy statement. It already gives a clear release date and effective time, and also specifies the applicable product category, required certificate type, language version, and issuing institution conditions; therefore, for relevant enterprises, it cannot be viewed only as a long-term trend.

However, from a prudent perspective, whether this change will form a completely consistent implementation result in different business scenarios still needs to be continuously observed in combination with subsequent detailed rules, path explanations, and market feedback. In particular, the certificate verification standards, the scope of white list application, and whether the procurement side will simultaneously raise the supplier threshold will all affect the actual friction after the rules take effect.

The focus for Vietnam-related business is shifting from products to manufacturer qualifications

Overall, the core signal released by Vietnam’s requirements for the import of photovoltaic cleaning equipment this time is: import compliance review is shifting from products and customs documents further to the manufacturer’s own energy management system certification. For Chinese manufacturers, this is not only related to the completeness of certificates, but also to export access efficiency and delivery schedule arrangements.

At present, it is more appropriate to understand this information as a regulatory change with a clear effective point, and also as a supervision trend that still needs to be tracked in the subsequent detailed implementation. For enterprises involved in the Vietnamese market, the most practical priorities in the short term remain verifying certificate conditions, advancing certificate preparation, and continuously monitoring whether the implementation path becomes clearer.

Basis of this article and follow-up verification direction
