Regulation (EU) 2023/1230, commonly known as the EU Machinery Regulation, is steadily approaching its full application date of 20 January 2027. We previously explored the Regulation’s main changes in our article explaining what truly differentiates it from the former Machinery Directive. In this article, we take stock of the latest developments, as the regulatory process has continued to evolve and several important updates deserve attention.
A quick reminder of the timeline
Before looking at the latest developments, it is worth briefly recalling the implementation schedule. The Regulation was published on 29 June 2023 in the Official Journal of the European Union, available on the EUR-Lex website, and entered into force twenty days later. Some provisions, including those concerning the notification of conformity assessment bodies, have already applied since 2024.
Most of the substantive obligations, however, will only become applicable on 20 January 2027, when the Machinery Directive 2006/42/EC will be fully repealed. With approximately six months remaining until that date, 2026 represents the final opportunity for companies to complete their compliance efforts, both from a technical and documentation perspective.
Harmonised standards: an issue still under development
One of the most closely monitored topics for manufacturers and compliance professionals is the status of the harmonised standards. The European standardisation organisations CEN and CENELEC are currently revising hundreds of technical standards to align them with the new requirements of the Regulation, particularly those relating to artificial intelligence, software, and cybersecurity resilience. According to the European Commission’s dedicated webpage, the objective is to adopt, by the end of 2026, an implementing decision containing the complete list of harmonised standards supporting the new Regulation.
In the meantime, the Commission has already adopted several implementing decisions updating the relevant standard references, with the latest published during the first months of 2026. Newly issued European standards will include not only the traditional Annex ZA, which relates to the former Machinery Directive, but also a new Annex ZB specifically addressing the Machinery Regulation. For companies, this means that much of their technical documentation will need to be reviewed, even where it is based on long-established standards that have been successfully applied for years.
This situation creates a degree of operational uncertainty. Many manufacturers are waiting for the final list of harmonised standards before carrying out a comprehensive revision of their technical files, in order to avoid having to repeat the process several times within the same year.
The Commission’s implementation guide
As was the case under the Machinery Directive, the new Regulation will also be accompanied by an official implementation guide designed to clarify its practical interpretation. The drafting working group met for the first time in January 2025, and work continued throughout the following year with the participation of national experts and industry associations.
The final guide is expected to be published by the end of 2026, in line with the Commission’s stated objective for the harmonised standards list, although draft versions may circulate informally before the official publication. This document will be particularly valuable in clarifying issues that remain open to interpretation, such as the treatment of substantial modifications to existing machinery and the application of the new requirements to partly completed machinery.
Companies involved in revamping and retrofitting production lines are closely following these developments, as the guidance will influence many practical decisions, including when modifications to an installation require a new conformity assessment.
The connection with the Cyber Resilience Act and NIS2
Among the most significant recent developments is the growing alignment between the Machinery Regulation and the EU’s broader cybersecurity legislation. The Cyber Resilience Act (Regulation (EU) 2024/2847) introduces horizontal cybersecurity requirements for products with digital elements, while the NIS2 Directive strengthens the resilience of information systems at organisational level.
The Machinery Regulation forms part of this wider legislative framework and follows the principles of the New Legislative Framework (NLF), the package of legislation adopted in 2008 (Regulation (EC) No 765/2008 and Decision No 768/2008/EC) establishing common rules for CE marking, accreditation of conformity assessment bodies and the obligations of economic operators across the EU’s product legislation.
This means that definitions such as manufacturer, authorised representative, importer, and distributor are harmonised across different regulations, together with a consistent approach to risk assessment. For manufacturers producing machinery with electronic components or embedded software, cybersecurity is therefore no longer a separate compliance issue but an integral part of the overall product safety strategy.
Machinery subject to mandatory third-party assessment
Another important update concerns the list of high-risk machinery contained in Annex I of the Regulation. Six categories of machinery and related products will require mandatory assessment by a notified body, regardless of whether harmonised standards have been applied:
- detachable mechanical transmission devices, including their guards;
- guards for detachable mechanical transmission devices;
- vehicle service lifts;
- portable cartridge-operated fixing and other impact machinery;
- safety components incorporating fully or partially self-evolving behaviour (machine learning) that perform safety functions;
- machinery integrating systems with the same type of self-evolving behaviour, where such systems are not placed on the market independently.
Under the previous Machinery Directive, compliance with harmonised standards could often be sufficient to demonstrate conformity. Under the new Regulation, this will no longer be the case for these specific categories.
This change will have a direct impact on certification timelines and costs for the manufacturers concerned. Companies will need to involve notified bodies much earlier in the conformity assessment process, particularly as their capacity is limited and demand is expected to increase significantly as the 2027 application date approaches.
What changes for technical documentation
Recent developments confirm a trend that had already emerged: the quality and consistency of technical documentation remain fundamental, but the scope of documentation requirements is expanding. Every document will need to accurately reflect the new provisions relating to artificial intelligence, cybersecurity, and substantial modifications, in line with the guidance that will be provided by the Commission’s implementation guide.
Language requirements also remain critical. Instruction manuals and EU declarations of conformity must continue to be translated into the official language(s) of every Member State where the machinery is placed on the market. However, the terminology involved is becoming increasingly sophisticated, covering areas such as artificial intelligence, cybersecurity, and self-evolving systems. In this context, an inaccurate translation is no longer merely a linguistic issue, it may directly affect the product’s compliance.
Companies that have already started reviewing their technical documentation should closely monitor the publication of both the final list of harmonised standards and the Commission’s official implementation guide, both expected, according to the Commission’s stated objectives, by the end of 2026. Updating and translating instruction manuals, declarations of conformity and internal procedures well in advance remains the most effective way to be fully prepared for 20 January 2027, avoiding last-minute compliance challenges.
