Effective June 1, 2026, the EU will officially implement the detailed rules of the Ecodesign for Sustainable Products Regulation (ESPR), requiring all industrial sensors exported to the EU (including pressure, temperature and humidity, and flow types) to be accompanied by a 'Digital Product Passport' certified by a recognized third-party body and a full life-cycle carbon footprint declaration. This requirement is directly related to the CE compliance pathway, testing costs, and delivery lead times of Chinese sensor export enterprises, and will have a substantial impact on such segmented links as sensor manufacturing, foreign trade agencies, testing and certification services, and upstream key component supply.

Event Overview

On May 17, 2026, the European Commission officially issued the detailed rules of the Ecodesign for Sustainable Products Regulation (ESPR), clarifying that from June 1, 2026, all industrial sensors exported to the EU (including pressure sensors, temperature and humidity sensors, and flow sensors) must be accompanied by a 'Digital Product Passport' issued by an EU-recognized third-party body and a carbon footprint declaration covering the entire process of raw material sourcing, production and manufacturing, transportation and distribution, use phase, and end-of-life disposal. This requirement is a mandatory compliance condition. Those that fail to meet it may not affix the CE mark and may not enter the EU market.

Which Segmented Industries Will Be Affected

Direct Trading Enterprises

Foreign trade companies engaged in sensor exports to Europe and ODM/OEM export-oriented enterprises will be directly restricted. Since the carbon footprint declaration must be issued by an EU-recognized third-party body, the existing CE certification process will need to additionally incorporate the LCA (Life Cycle Assessment) stage, resulting in longer certification cycles and higher costs for each product batch. Some small and medium-sized enterprises may face the risk of incomplete export documentation and customs clearance obstacles.

Processing and Manufacturing Enterprises

Sensor complete-unit manufacturers need to systematically sort out their own supply chain carbon data collection capabilities. At present, most domestic manufacturers have not yet established carbon emission databases covering upstream materials (such as ceramic substrates, MEMS chips, PCB, packaging adhesives, etc.), and also lack mechanisms to collaboratively collect original energy consumption and logistics data with suppliers, making it difficult to independently complete LCA reports that meet EU requirements.

Supply Chain Service Enterprises

Business demand for third-party institutions providing testing, certification, LCA modeling, and digital passport generation services will rise in phases. However, it should be noted that institutions with only CNAS qualifications or domestic dual-carbon service experience do not automatically obtain EU recognition; enterprises must confirm whether their partners have been included in the 'List of Recognized Third-Party Bodies' officially published by the EU (EU Commission’s List of Notified Bodies for ESPR).

Raw Material Procurement Enterprises

Upstream suppliers that provide supporting materials such as sensitive components, housing structural parts, and cable assemblies for sensors may be required by downstream complete-unit manufacturers to provide material-level carbon data (such as aluminum smelting power consumption and PCB copper-clad laminate resin carbon intensity). At present, such data is generally lacking in domestic supply chains, which will force some tier-one suppliers to initiate carbon inventory and disclosure capability building.

What Key Points Should Relevant Enterprises or Practitioners Pay Attention To, and How Should They Respond at Present

Pay Attention to Updates to the Latest Official EU List of Recognized Third-Party Bodies

Although the detailed ESPR rules have now been issued, the European Commission has not yet simultaneously disclosed the first batch of third-party institutions authorized to carry out LCA verification and digital passport issuance for sensor products. Enterprises should continuously track the Official Journal of the European Union and the website information of the Ecodesign Coordination Centre to avoid commissioning unauthorized institutions that could result in invalid reports.

Differentiate Key Product Categories for Priority Adaptation Rather Than Blindly Covering the Entire Series for the Time Being

The new regulation clearly applies to 'industrial sensors', but it does not further define technical thresholds (such as measurement accuracy, operating temperature, communication protocols, etc.). From an industry perspective, pressure and flow sensors with high added value, long delivery cycles, and already included in key EU regulatory catalogs (such as the scope applicable under the EN 61000-6-4 electromagnetic compatibility directive) are more likely to become the first targets of customs inspection; general-purpose temperature and humidity sensors may have a transitional observation period. Enterprises may accordingly launch carbon footprint accounting preparations in batches.

Start Building Internal Data Interfaces in Advance Rather Than Relying Solely on External Report Procurement

Carbon footprint declarations must be based on real production data and cannot be estimated solely using industry default values (default values). Analysis shows that enterprises equipped with ERP/MES systems and already connected to energy metering instruments can complete the establishment of basic data links within 3–6 months; enterprises without a digital foundation need to reserve at least 6 months for the design of production-line energy consumption allocation models and the establishment of supplier data collaboration mechanisms. What deserves more attention at present is the granularity of internal data collection (such as aggregating electricity and steam consumption by model/work order/shift), rather than immediately purchasing a full set of LCA software.

Synchronize the Review of the CE Technical Documentation Update Rhythm to Avoid Compliance Gaps

The additional ESPR requirements do not replace the technical documentation under existing CE directives (such as EMC, LVD, and RoHS), but serve as supplementary annexes to them. Enterprises must ensure that in the updated technical documentation, the document numbers, version numbers, and issue dates of the carbon footprint declaration and digital passport are logically consistent with the CE Declaration of Conformity. If the original CE certificate is still within its validity period, the corresponding annexes must still be supplemented according to ESPR requirements; otherwise, it will be regarded as incomplete compliance.

Editorial Viewpoint / Industry Observation

Observably, this new regulation is currently better understood as a key signal that the EU is extending carbon regulation from the end-consumer side (such as batteries and textiles) to intermediate industrial products, rather than as a mature mechanism that has already been fully implemented. On the one hand, the detailed rules have just been issued, and supporting technical guidelines (such as the definition of LCA accounting boundaries for sensor categories, secondary data default value databases, and digital passport data format standards) have not yet been introduced; on the other hand, the actual enforcement details, sampling ratios, and penalty scales for violations by customs authorities of EU member states remain to be observed. Analysis shows that its short-term direct impact is concentrated on leading enterprises with relatively large export volumes and increasingly stringent customer audits, while for small and medium-sized exporters it is more reflected as pressure in compliance expectation management. The industry needs to continue paying attention to the first batch of assessment cases and notifications of common non-compliance items issued by market surveillance authorities of EU member states starting from the third quarter of 2026.

Conclusion: This new regulation marks that the EU is deeply embedding climate policy into the market access system for industrial products. Its core significance does not lie in immediately raising export barriers, but in driving the global sensor industry chain to accelerate the construction of verifiable, traceable, and mutually recognizable carbon data infrastructure. At present, it is more appropriate to understand it as a regulatory-driven process of systematic capability preparation—enterprises do not need to respond in haste, but must avoid simply equating carbon footprint work with 'doing one more report'; instead, they should regard it as a comprehensive test of supply chain transparency and manufacturing digitalization level.
