EU Machinery Regulation 2023/1230: what changes in January 2027 for integrators

On 20 January 2027, the EU Machinery Regulation (EU) 2023/1230 replaces the Machinery Directive 2006/42/EC. For system integrators — who routinely become the manufacturer of the assemblies they build — the change is less a revolution than a tightening: the core method stays, but several grey areas are now written into law.

This article covers what stays the same, what changes in practice for integrators, and what to put in place before your first project that is placed on the market after the deadline.

Key dates

Milestone	Date
Published in the Official Journal	29 June 2023
Entered into force	19 July 2023
Provisions on notified bodies apply	20 January 2024
Regulation applies; Directive 2006/42/EC repealed	20 January 2027

What counts is the date the machine — or the assembly — is placed on the market or put into service, not the date the contract was signed. A line ordered in 2026 and commissioned in February 2027 falls under the Regulation.

What stays the same

• Risk assessment remains the foundation. You still determine the limits of the machinery, identify hazards, estimate and evaluate risk and apply the three-step method. EN ISO 12100 remains the reference method.
• Assemblies of machinery. If you arrange and control machines so that they function as an integrated whole, you are the manufacturer of the assembly and responsible for its conformity assessment, technical documentation, Declaration of Conformity and CE marking.
• Partly completed machinery. Suppliers still provide a Declaration of Incorporation and assembly instructions. These remain key inputs to your risk assessment for the assembly.
• Harmonised standards still provide a presumption of conformity — once their references are published in the Official Journal under the Regulation.
• Technical documentation must still be kept for at least 10 years.

What changes for integrators

1. A Regulation, not a Directive

The Regulation is directly applicable in every member state. There is no national transposition, so the legal text is the same wherever your customer is. Northern Ireland generally continues to follow EU product rules under the Windsor Framework; Great Britain keeps its own supply legislation.

2. Substantial modification is now defined in law

Retrofits, line rebuilds and relocations are core integrator work, and under the Directive the threshold for “new machine” was mostly guidance. The Regulation defines a substantial modification as a physical or digital modification, not foreseen or planned by the original manufacturer, that affects safety by creating a new hazard or increasing an existing risk, so that new protective measures are needed.

Whoever carries out a substantial modification is treated as the manufacturer — for the part affected, or for the whole machine where the modification affects the safety of the whole. In practice that means a risk assessment, technical documentation and a Declaration of Conformity for the modification. Integrators need a documented, repeatable way to decide whether a change is substantial — and to evidence that decision.

3. Control systems and protection against corruption

Annex III updates the essential health and safety requirements. Two points matter for every integrator who connects machines to networks:

• Protection against corruption. Connecting another device or using remote access must not lead to a hazardous situation, and safety-related software and data must be protected against accidental or intentional corruption.
• Safety and reliability of control systems. Control systems must withstand the intended operating stresses and external influences — explicitly including reasonably foreseeable malicious attempts by third parties that could lead to a hazardous situation.

Network architecture, remote-access design and software version control now sit inside the safety case, not next to it.

4. High-risk machinery and self-evolving behaviour

Annex I lists high-risk machinery in two parts. Part A categories always need a notified body. These include safety components with fully or partially self-evolving behaviour using machine learning approaches that ensure safety functions, and machinery with such embedded systems. Part B categories may use internal production control if harmonised standards covering all relevant requirements are fully applied.

If you integrate AI-based vision or safety systems, check early whether they fall under Part A.

5. Digital instructions and declarations

Instructions may be supplied in digital form. A paper copy must be provided free of charge if the customer requests it at the time of purchase, and essential safety information must be provided on paper where machinery is intended for, or likely to be used by, non-professional users. The EU Declaration of Conformity follows the content set out in Annex V.

6. Importers and distributors have explicit obligations

The Regulation aligns machinery with the EU New Legislative Framework. If you import machines from outside the EU to integrate them, check whether you are acting as an importer and what that obliges you to verify.

A preparation checklist for integrators

• List every project that will be placed on the market or put into service on or after 20 January 2027.
• Update risk assessment templates for the revised Annex III requirements, including protection against corruption, control system reliability, and human–machine interaction.
• Review your list of applied standards against the references published under the Regulation.
• Write a procedure for deciding — and documenting — whether a retrofit or rebuild is a substantial modification.
• Update Declaration of Conformity and Declaration of Incorporation templates to the Regulation’s annexes.
• Decide how you will deliver instructions (digital, paper, or both) and how paper requests are handled.
• Ask suppliers when they will provide declarations that reference Regulation (EU) 2023/1230.
• Check whether any safety component you integrate falls under Annex I Part A.

Where MSA fits

The work above is mostly about keeping a large body of evidence consistent while requirements change. MSA keeps the risk assessment, PLr / SIL calculations, validation protocols, FAT/SAT test packs and CE Technical File in one traceable model, so one change regenerates every affected document. MSA is designed to be ready for the EU Machinery Regulation from 2027 and runs 100% offline.
