The European Commission formally adopted the REACH amendment ((EU) 2026/XXXX) on May 1, 2026, introducing new restrictions on pressure sensors with nickel-containing metal housings, and explicitly prohibiting from December 2026 the use of non-exempt electroplating processes with a nickel release rate >0.5μg/cm²/week. This policy directly affects major export product categories for the EU market, such as stainless steel housing pressure sensors and miniature pressure transmitters, and relevant companies need to focus on trade compliance, process substitution, and supply chain adjustment.

Event Overview

The European Commission formally adopted the amendment to Annex XVII of the REACH Regulation ((EU) 2026/XXXX) on May 1, 2026, adding Entry 73 restriction provisions: any metal housing used for pressure sensors that has undergone electroplating treatment and has a nickel release rate exceeding 0.5μg/cm²/week will be included in the restricted substances list; exemptions apply only to medical-grade or aerospace-grade products certified under the EN 1811:2023 standard. This restriction will officially take effect on December 1, 2026.

Which Market Segments Will Be Affected

Direct Trading Companies

Pressure sensor finished-product manufacturers and foreign trade agencies exporting to the EU will directly face compliance market entry barriers. The impact is mainly reflected in: nickel release test reports must be provided before CE marking is affixed to products; models using existing electroplating processes that have not obtained EN 1811:2023 certification may be unable to continue customs clearance; the annual export value from China to Europe involved is estimated at approximately 1.2 billion euros.

Processing and Manufacturing Companies

Contract factories and OEM manufacturers responsible for sensor housing electroplating and surface treatment are facing pressure to restructure their processes. The impact is mainly reflected in: existing medium- and low-nickel-release electroplating lines need to be revalidated for compliance with the 0.5μg/cm²/week limit; some composite electroplating solutions using traditional nickel undercoats + decorative chromium layers may fail to meet the requirements; production line commissioning and third-party testing cycles will extend delivery lead times.

Raw Material Procurement Companies

Companies supplying stainless steel housings, nickel-based alloy billets, or electroplating chemicals for sensors need to respond to upgraded downstream technical specifications. The impact is mainly reflected in: customers are imposing higher requirements on the stability of nickel precipitation from base materials; electroplating additive suppliers need to provide process packages and declaration documents compliant with the limit values in REACH Annex XVII; some low-cost nickel salts or nickel-containing brighteners may be required to be replaced.

Supply Chain Service Companies

Demand is increasing for service providers offering REACH compliance consulting, testing and certification, and technical documentation preparation. The impact is mainly reflected in: orders for dedicated nickel release testing for pressure sensor housings (according to EN 1811:2023) are expected to increase; customers need assistance in distinguishing between the two applicable pathways of “medical/aerospace exemption” and “general industrial”; testing cycles, report formats, and coordination requirements with the EU Authorized Representative (OR) are becoming increasingly stringent.

What Key Points Should Relevant Companies or Practitioners Focus On, and How Should They Respond at Present

Confirm Whether Products Fall Within the Scope of the Restriction

Immediately sort out the list of pressure sensor models exported to Europe, and identify housing materials (such as 304/316 stainless steel), surface treatment methods (whether they include electroplated nickel layers), and application scenarios (whether they are claimed for medical or aerospace use). For non-exempt products, actual nickel release testing must be completed and reports archived before December 2026.

Launch an Evaluation of Electroplating Process Substitution

Priority should be given to evaluating the feasibility of nickel-free plating solutions (such as electroless nickel-phosphorus plating, stainless steel nitriding enhancement, and PVD physical vapor deposition) or low-release nickel plating layers (such as high-phosphorus nickel and optimized pulse electroplating); at the same time, contact existing plating factories to confirm whether they already have EN 1811:2023 testing capability and certification qualifications, so as to avoid delivery delays caused by temporary switching.

Pay Attention to Official Interpretations of the Boundaries of Exemption Applicability

EN 1811:2023 certification is currently mainly intended for piercing/implant devices that come into direct contact with the human body. If pressure sensors are used in equipment such as ventilators and dialysis machines, the end medical device manufacturer needs to issue an application declaration; exemption is not granted automatically merely based on the housing material. It is recommended to communicate in advance with the EU Authorized Representative regarding the preparation pathway for exemption materials.

Reserve a Time Window for Testing and Documentation Updates

Nickel release testing must be conducted according to EN 1811:2023 as a one-week simulated wear immersion test, and the testing cycle for a single batch is usually 10–15 working days; it is recommended to complete submission of the first batch of samples for testing before the end of August 2026, and simultaneously update the technical documentation (DoC), Safety Data Sheet (SDS), and the nickel content declaration in labels.

Editorial Viewpoint / Industry Observation

Observably, this amendment is not a sudden regulatory escalation, but a continued implementation of REACH's long-term focus on nickel sensitization risks; what is currently more worthy of attention is the granularity of its enforcement——the restriction precisely targets the “electroplating process” rather than the nickel element itself, meaning that non-electroplating nickel treatment methods such as mechanical polishing and laser cladding are temporarily not subject to restriction. Analysis shows, this amendment essentially extends the original medical device regulatory logic (EN 1811) to the industrial sensor field, and its signaling significance is greater than its immediate impact: it marks that the EU is treating “contact metal release” as one of the core evaluation dimensions of industrial product chemical safety. From an industry perspective, this is not an isolated provision, but may indicate a subsequent trend of similar regulation for housings of comparable contact-type instruments such as temperature sensors and flow meters.

Conclusion

This REACH amendment marks that the EU's chemical safety compliance requirements for industrial sensor products have entered a more refined stage. Its core impact lies not in a comprehensive ban on nickel, but in forcing companies to establish a verifiable and traceable process control system for surface treatment. At present, it is more appropriate to understand it as a compliance transition arrangement “driven by testing to promote process upgrading” rather than an insurmountable technical barrier; whether companies can respond smoothly depends on whether they have incorporated material safety data management into their routine R&D and supply chain processes.
