Starting September 1, 2026, the EU's restrictions on PFAS-based water-repellent and stain-resistant coatings used in photovoltaic cleaning equipment will enter the implementation stage. This adjustment does not impose a generalized requirement at the level of the complete machine; instead, it focuses on material and coating compliance for specific components such as nozzle seals, hose outer layers, and protective covers. For photovoltaic cleaning equipment manufacturers, exporters, purchasers, and supporting component suppliers serving the EU market, the key concern is not only the scope of the ban itself, but also the requirement for imported products to provide a declaration of conformity and third-party test reports. This means that compliance reviews have directly entered the delivery and trade processes.

Confirmed Elements of This Regulatory Adjustment

According to the confirmed information, the European Commission issued the revised REACH Regulation ((EU) 2026/1422) on August 8, 2026, adding per- and polyfluoroalkyl substances (PFAS) to Entry 77 of Annex XVII and explicitly prohibiting the use of PFAS-based water-repellent or stain-resistant coatings in components such as nozzle seals, hose outer layers, and protective covers of photovoltaic cleaning equipment.

The new regulation provides a six-month transition period and will take effect on September 1, 2026. The rules apply to imported products in all Member States, and the relevant products must be accompanied by a declaration of conformity and third-party test reports.

The Impact Is Extending Across Multiple Business Processes

Complete Equipment and Equipment Suppliers Exporting to the EU

From an industry perspective, these companies are affected most directly because whether a product can enter the EU market now depends not only on the equipment's functions, but also on whether specific components involve PFAS-based water-repellent or stain-resistant coatings. The main impacts are reflected in product selection, material verification, compliance document preparation, and the completeness of export delivery documentation. Of greater concern at present is the need for companies to match component-level material information with complete-machine export documents, thereby avoiding situations in which the equipment can be shipped but the documents cannot support import compliance.

Supporting Companies Involved in Components and Outsourced Processing

For suppliers of relevant components such as nozzle seals, hose outer layers, and protective covers, this change will directly affect their material usage and surface treatment solutions. Analysis indicates that even if a company does not sell directly to the EU, its products may still be part of the photovoltaic cleaning equipment supply chain and customers may require additional material descriptions, declarations of conformity, or third-party testing support. The key point is that customer audits may extend from the complete-machine manufacturer to the component and processing stages, making documentation transparency part of the transaction requirements.

Procurement, Import, and Channel Distribution

For purchasers, importers, and channel distribution companies, the pressure brought by the new rules lies mainly not in sales promotion, but in preliminary review and the control of compliance risks upon arrival. Since the rules clearly apply to products imported into Member States, procurement and import processes need to verify whether suppliers can provide complete declarations of conformity and third-party test reports. Based on current observations, key changes in subsequent business activities may involve sample confirmation, batch document retention, delivery document verification, and customer traceability requirements.

End Users and Project Execution

Although end-user companies or service providers using photovoltaic cleaning equipment may not directly bear manufacturing responsibility, they will still face issues concerning proof of equipment compliance during procurement and project execution. In particular, during equipment import, acceptance, or supplier selection, the completeness of compliance documents may become part of the procurement decision. It should be noted that this impact is more reflected in higher procurement review and supplier communication thresholds, rather than in confirmed market outcomes contained in the input information.

What Practical Issues Should Companies Focus on Now?

First Confirm the Specific Components and Coatings Affected

Companies should first return to the product structure itself and determine whether nozzle seals, hose outer layers, protective covers, and other components use PFAS-based water-repellent or stain-resistant coatings. The key issue is not merely the product name, but the actual materials and surface treatment used for the components. If the relevant information is incomplete, it will affect the timeline of subsequent declaration issuance and testing arrangements.

Move Compliance Document Preparation Forward to Before Shipment

The confirmed rules require a declaration of conformity and third-party test reports. Therefore, companies cannot wait until customers request them temporarily before preparing compliance documentation. Based on the analysis, a more practical approach is to incorporate document preparation into the pre-shipment process, including supplier data collection, testing arrangements, document version management, and confirmation of the customer delivery checklist.

Focus on Closing the Documentation Loop in Import Operations

For businesses involving imports into EU Member States, companies need to focus not only on whether production has been completed, but also on whether the documentation can support customs clearance, acceptance, and customer record retention. Of greater concern at present is whether the business, procurement, and compliance teams have established a consistent position, so as to avoid inconsistencies among commercial commitments, technical documents, and testing documents.

Continue Monitoring Official Wording and Customer Implementation Practices

Although the input information has clarified the prohibited scope, effective date, and documentation requirements, how customers conduct verification, how procurement documents are worded, and how third-party test reports are accepted remain matters requiring continuous attention at the implementation level. Based on current observations, companies need to monitor both subsequent changes in official wording and specific implementation requirements on the customer side.

This Is More Like a Signal That Compliance Requirements Are Moving Upstream

The following content constitutes observation and analysis. Based on the current information, this news is more appropriately understood as a further specification of the EU's material compliance requirements for photovoltaic cleaning equipment, rather than simply the addition of an abstract environmental statement. Its signal is that regulation has been extended to specific components and specific documentation requirements, meaning that material traceability and the completeness of supporting documents will become more important for industry participants entering the EU market in the future.

At the same time, this change should not be simply exaggerated as evidence that definitive changes have already occurred across the entire industry. What has been clearly established at this stage is the prohibited subject matter, implementation date, and import documentation requirements. Changes in enterprise costs, the pace of supply chain substitution, and the intensity of customer acceptance inspections remain matters for subsequent observation and should not currently be presented as established facts.

The Practical Significance for the Industry Still Lies at the Implementation Level

Overall, the industry significance of this news is that the EU market's compliance focus for photovoltaic cleaning equipment has extended from requirements concerning the outcome of market entry to the level of component materials and supporting documentation. For companies, the most realistic short-term impact is an increase in product review, document preparation, and supply chain communication. In the longer term, the signal is that related business will rely more heavily on verifiable material information and third-party evidence.

Therefore, it is currently more appropriate to understand this development as an implemented compliance change and, at the same time, as an industry signal requiring continued observation of implementation details. It is not ordinary policy noise, but neither should it be interpreted as meaning that all subsequent impacts are already fully clear.
