Starting August 15, 2026, the updated Resolution No. 12/2026 of Brazil's National Institute of Metrology, Standardization and Industrial Quality (INMETRO) will take effect. Imported photovoltaic cleaning and O&M equipment must bear localized Portuguese energy-efficiency labels and complete verification by an authorized laboratory. This change deserves close attention from exporters of photovoltaic O&M equipment, manufacturers, labeling and compliance service providers, as well as distributors and purchasing parties serving the Brazilian market, because it directly relates to pre-market labeling compliance, verification procedures, delivery arrangements, and the cost of localized adaptation.

What the Rule Adjustment Clearly Specifies

The confirmed information indicates that INMETRO updated Resolution No. 12/2026 on August 4, 2026, requiring all imported photovoltaic cleaning and O&M equipment to bear Portuguese energy-efficiency labels from August 15 onward. The label must include at least three parameters: energy-efficiency rating, annual power consumption, and Cleaning Efficiency Energy Ratio (CEER). At the same time, the relevant labels must be verified by an INMETRO-authorized laboratory before they can be used. The information provided also clearly indicates that this requirement will affect the labeling costs and localized adaptation capabilities of Chinese manufacturers exporting to Brazil.

The Impact Goes Beyond Labeling, and the Entire Business Chain Will Face Pressure

Equipment Manufacturers Exporting to Brazil

From an industry perspective, photovoltaic cleaning and O&M equipment companies shipping directly to the Brazilian market will be affected first. The reason is that the new regulation does not merely add a text translation requirement; it also links the Portuguese label content to laboratory verification. The main impacts will be reflected in pre-shipment label preparation, parameter confirmation, document organization, and compliance review. Companies need to pay particular attention to the consistency between label information and the actual equipment parameters, as well as whether verification arrangements may affect the shipping schedule.

Manufacturing and Product Management

For processing and manufacturing enterprises and product management teams, the impact is more closely related to internal process adjustments. Based on current observations, the inclusion of energy-efficiency rating, annual power consumption, and CEER in the labeling requirements means that product documentation, nameplate information, packaging marks, and external documents need to remain coordinated. The changes requiring attention mainly concern localized version management, label changeover mechanisms, and consistency in the presentation of parameters across products from different batches.

Distributors, Purchasers, and Delivery Coordination Parties

Distribution companies, purchasers, and supply chain service providers involved in cross-border delivery will also be affected indirectly. This is because the regulation has a clearly defined and relatively close implementation date, and insufficient preparation at any labeling or verification stage may be passed on to customs clearance, receipt of goods, delivery commitments, and customer communications. The relevant parties need to focus not only on individual cost changes, but also on timing risks in order execution, document completeness, and whether the division of responsibilities is clear.

Several Practical Issues That Deserve Greater Attention from Companies

First Confirm the Applicable Product Categories and Shipments in Transit

Based on the analysis, companies should first verify whether their products exported to Brazil fall within the scope of photovoltaic cleaning and O&M equipment, and promptly identify projects involving shipments, goods in transit, or pending deliveries around August 15. The focus here is not to broaden the interpretation, but to match the applicable objects of the regulation with specific orders one by one, thereby avoiding deviations in labeling, documentation, or delivery milestones later on.

Handle Label Content and Verification Requirements within the Same Process

The new regulation concerns not only the Portuguese label itself, but also the prerequisite that the label be verified by an INMETRO-authorized laboratory. For companies, a more practical approach is to treat label text, localized parameter presentation, and verification document preparation as one integrated task rather than handling them separately. Attention should be paid to whether the presentation of the three parameters, internal recordkeeping, and externally submitted materials correspond with one another.

Reassess Delivery Schedules and Communication Guidelines

The implementation date of this regulation is relatively close, so companies need to reassess the pace of order confirmation, shipping commitments, and customer communications from a business perspective. For projects that have already entered the implementation stage, greater attention should be paid to whether there is any timing mismatch between label production, verification arrangements, and logistics milestones. Companies should also clarify the submission of documents and the division of responsibilities with customers, distributors, or partners in advance.

Continue Monitoring Subsequent Official Statements

Although the currently known requirements are relatively clear, companies still need to continue monitoring whether more detailed implementation policies, explanatory documents, or supporting guidelines will be issued. It is important to distinguish between the requirements proposed in the policy text and the specific interpretation of materials, formats, and verification procedures during actual implementation. Therefore, subsequent official statements remain an important area of attention.

This Appears More Like a Signal That the Compliance Threshold Is Moving Earlier

As an observation rather than a predetermined conclusion, this information is currently better understood as indicating that the Brazilian market has introduced clearer and more localized requirements for compliance communication relating to photovoltaic O&M equipment. The direct change is the implementation of labeling and verification requirements, but what deserves greater attention is that preparation before equipment enters the target market is moving earlier in the process. Companies can no longer regard labeling as an additional task to be handled only shortly before shipment. At the same time, it is not advisable at this stage to interpret this broadly as meaning that all business outcomes have already been determined, because the actual degree of impact will also depend on each company's product lines, order schedules, and subsequent implementation details.

The Short-Term Focus Is Implementation, while the Long Term Depends on Continued Developments

Overall, in the short term, this new regulation will first appear as a clear implementation change: from August 15, the relevant imported photovoltaic cleaning and O&M equipment must meet the requirements for Portuguese energy-efficiency labels and verification by an authorized laboratory. It is more appropriate to understand this as both an immediate compliance matter and a market signal worth continuing to monitor. For industry participants, the current priority is not to overstate its implications, but to promptly coordinate labeling, verification, documentation, and delivery schedules while observing whether subsequent implementation policies become clearer.

Basis of This Article and Directions for Further Verification

This article was generated based on the information title, event date, and event summary provided by the user. The information used includes the event title, the implementation date of August 15, 2026, and summary content concerning INMETRO's update of Resolution No. 12/2026, label parameter requirements, and verification requirements imposed by authorized laboratories. This type of information generally requires continued verification against official announcements, documents issued by standards organizations, corporate announcements, industry association information, and reports from authoritative media. Since no specific link to an official source was provided in the input, the relevant statements still require further confirmation through subsequent review of formal documents. Further attention may be given to the specific implementation policies, the boundaries of applicable product categories, and details of the verification process.
