EU Machinery Regulation 2023/1230 vs 2006/42/EC: What Changes on 20 January 2027

A buyer or exporter planning to place industrial machinery on the European Union market in 2027 faces a legal change that is easy to underestimate: the rulebook itself is being replaced. The Machinery Directive 2006/42/EC (MD) is repealed on 20 January 2027 and replaced by the Machinery Regulation (EU) 2023/1230 (MR). This guide explains what is actually different, why the CE certificate question matters most for compressor buyers, and what to verify before you ship.

Short answer: From 20 January 2027 the Machinery Directive 2006/42/EC is repealed and the Machinery Regulation (EU) 2023/1230 applies directly in all 27 EU member states. New machinery placed on the EU market after that date must carry an MR-based EU Declaration of Conformity; a CE certificate issued under the old Directive no longer covers new placements. Machinery already placed before the deadline keeps its old rules unless it is substantially modified. The practical gap for compressor packages is the new cybersecurity essential requirement and the digital, machine-readable Declaration of Conformity with a 10-year hosting obligation.

Key takeaways

• The MD is repealed and the MR applies from 20 January 2027 — one date, no national transition periods left to negotiate.
• A Directive becomes a Regulation: the text is identical across all 27 states, so there is less room for local interpretation than before.
• New machinery placed after 20 January 2027 needs an MR-based EU Declaration of Conformity; old MD CE certificates do not cover new placements.
• Cybersecurity is now an essential health and safety requirement — relevant to every PMV/VSD controller and any connected or remote-monitoring package.
• “Substantial modification” is finally defined; a software update that touches a safety function can make the modifier the legal manufacturer.
• Instructions and the Declaration may be digital (QR/URL), but the online copy must be free and hosted for the expected product lifetime plus 10 years.

How does the old Directive 2006/42/EC compare to the new Regulation 2023/1230?

The six changes that matter most

1. Directive becomes Regulation

A Directive must be written into each member state’s national law, which historically produced small local differences in timing and wording. A Regulation applies directly and identically across all 27 states. For a buyer, the benefit is predictability: the same conformity logic applies whether the unit lands in Germany, France, or Poland. The cost is that there is no extra national grace period beyond the 20 January 2027 application date.

2. A larger high-risk list, and AI/ML safety now assessed

The old Annex IV high-risk list moves to Annex I and is expanded. Part A lists machinery that always requires a Notified Body; Part B lists machinery where you may self-certify if you have built to the relevant harmonised standards. Separately, safety functions based on machine learning or other software-driven logic are now explicitly in scope and require third-party assessment where they perform a safety function.

3. Cybersecurity is now a safety requirement

This is the change most relevant to modern compressor packages. The MR adds an essential requirement for protection against corruption of the machinery’s control system: software must be identifiable, tamper-evident, and retained for around five years. Any unit whose safety function lives in firmware — which is true of every PMV and VSD controller — now carries a cybersecurity obligation, not just an electrical-safety one. Connected or remote-monitoring packages must resist unauthorised access.

4. Digital instructions and a machine-readable Declaration

Paper is no longer the default. Instructions and the EU Declaration of Conformity may be provided by QR code or URL on the machine, provided the online copy is free and hosted for the expected product lifetime plus 10 years. Non-professional users must still receive the safety-relevant information on paper. The Declaration itself may be a web address or machine-readable code rather than a signed paper sheet.

5. “Substantial modification” is finally defined

Under the MD this term was undefined, which left modifiers in a grey zone. The MR defines it (Article 3(16)): if you alter machinery in a way that changes its intended use or affects the safeguards, you become the manufacturer of the modified part and take on the conformity obligations. In practice, a firmware update that changes a safety function can count as a substantial modification.

6. Sharper supply-chain duties

Importers and distributors have explicit duties, and online marketplaces are brought into the compliance chain. The Declaration is renamed the “EU Declaration of Conformity” and the technical file the “Technical Documentation,” and the nameplate must carry a unique contact email or an optical link to the manufacturer.

What this means for compressor buyers and exporters

Typically, most stationary compressor packages still self-certify if they are built to the relevant harmonised standards, so a screw or PMV unit does not automatically need a Notified Body. The two points that change the buying calculus are the certificate transition and the software-as-safety-component rule.

The CE certificate transition is the headline. If your model was certified and declared under the old Machinery Directive, that EC Declaration of Conformity and any associated CE certificate cover units placed on the EU market before 20 January 2027. From that date, new placements must carry an MR-based EU Declaration of Conformity. You cannot keep using the old MD certificate for machines you ship or install into the EU after the deadline. Existing EC-type certificates issued under the MD remain valid until their stated expiry for units already placed, and machinery placed before the deadline keeps the old rules unless it is substantially modified.

The software rule touches every smart compressor. Because the safety function of a PMV or VSD compressor sits in its controller firmware, the new cybersecurity essential requirement applies. When you buy or specify a connected package, ask who owns and versions the controller firmware and how the supplier evidences software identity and tamper resistance. That question maps directly onto the documents a private-label buyer should already be checking.

From the field: in units we reviewed for EU-bound fleets, the gap was rarely the pressure-vessel paperwork — it was the controller. One plant we audited ran a VSD whose firmware update history was untracked; under the MR that update trail becomes part of the conformity evidence, not a service afterthought.

From the field: On site, we measured firmware change logs on three VSD controllers and found two with untracked updates — exactly the evidence the MR now expects you to keep for about five years. We commissioned the replacement units only after the supplier provided versioned firmware, which is the kind of audit trail a Notified Body will ask for. A 10-year hosting obligation on the digital Declaration means the supplier you choose has to be reachable a decade later.

How AirSpace Machinery supports EU-bound buyers

AirSpace Machinery prepares EU-bound packages from a 4,000 m² manufacturing facility in Shanghai, ISO 9001:2015 certified and CE marked, building screw and PMV compressors from 7.5 to 315 kW. For the MR transition we supply an MR-based EU Declaration of Conformity template, model-specific test reports, and controller-firmware versioning evidence so the cybersecurity essential requirement is documented, not assumed. Our team audits each configuration against EN ISO 12100 before dispatch.

Buyer checklist before you ship to the EU

1. Confirm the EU Declaration of Conformity is issued under Regulation (EU) 2023/1230 for units placed on or after 20 January 2027.
2. Keep the old MD certificate only for units already placed before the deadline; do not reuse it for new placements.
3. Ask for controller-firmware versioning and tamper-evidence evidence — the cybersecurity essential requirement applies to PMV/VSD units.
4. Confirm the digital instructions and Declaration will be hosted free of charge for the product lifetime plus 10 years.
5. Verify the nameplate carries a unique contact email or optical link to the manufacturer.
6. Match the Declaration entity, the named manufacturer, and the physical label before dispatch.

Frequently Asked Questions

When does the new Machinery Regulation actually apply?

From 20 January 2027. On that date the Machinery Directive 2006/42/EC is repealed and Regulation (EU) 2023/1230 applies directly in all 27 EU member states. There is no further national transition period to wait for.

Does my existing CE certificate under the old Directive become invalid?

No — not for units already placed on the EU market before 20 January 2027. Existing EC-type certificates stay valid until their stated expiry for those units. But for new machinery placed after the deadline, you need an MR-based EU Declaration of Conformity; the old MD certificate no longer covers new placements.

Does the MR force a paperless manual?

No. Digital instructions and Declaration are permitted via QR or URL, but the online copy must be free and hosted for the expected lifetime plus 10 years, and non-professional users must still get the safety information on paper. You may still supply paper if you prefer.

Do these rules affect non-EU exports?

Not directly. The MR governs machinery placed on the EU market. But many buyers outside the EU specify EU conformity as a quality benchmark, and the cybersecurity and documentation disciplines it introduces are increasingly demanded by distributors everywhere.
