A machinery upgrade, automation project or control-software change does not automatically require a new CE route. Equally, calling work a “retrofit” does not by itself settle the compliance responsibility. Regulation (EU) 2023/1230 is already in force and will generally apply from 20 January 2027. Where an alteration meets its test for a substantial modification, the party making that alteration may become the manufacturer of the machinery concerned, or of the affected part.
This is a transition-readiness note, not a claim that the new Regulation is universally applicable today. The European Commission states that machinery placed on the EU market before 20 January 2027 must still comply with the current Machinery Directive 2006/42/EC.
The legal test is narrower than “any upgrade”
Article 3(16) of the Machinery Regulation does not treat maintenance, refurbishment, software work and production-line upgrades as interchangeable labels. Its definition calls for a structured review. Teams should consider whether the change:
- takes place after the machinery or related product has been placed on the market or put into service;
- is physical or digital, and was not foreseen or planned by the original manufacturer;
- creates a new hazard or increases an existing risk; and
- requires protective measures involving the safety control system, or additional measures to ensure stability or mechanical strength.
The facts matter. An additional station, for example, may have a very different compliance impact depending on changes to guarded areas, speed, access, interlocks and control logic. Conversely, a replaced component is not, on its own, proof of a substantial modification.
When the modifier may be treated as the manufacturer
Article 18 creates a defined responsibility route. A natural or legal person that carries out a substantial modification is deemed to be the manufacturer of the machinery or related product concerned, and must meet the relevant manufacturer obligations in Article 10 and use the applicable conformity-assessment procedure under Article 25.
That route depends on the Article 3(16) test being met; it is not a blanket rule that makes every service provider, equipment owner or integrator the manufacturer. Article 18 also sets a boundary for a non-professional user making a substantial modification for that user’s own use. For commercial projects, a conclusion on legal role and responsibility should be based on the full facts and, where appropriate, EU legal advice.
Build an evidence file before the work begins
Before changing machinery that will continue to be used, supplied or placed on the EU market, teams can build a practical modification record. It should connect the original machine to the altered configuration rather than merely state an outcome.
- Preserve the original risk assessment, drawings, instructions, declarations and control-programme versions.
- Describe the purpose of the change, the hardware and software delta, and what the original manufacturer anticipated.
- Record newly introduced hazards, risk-reduction measures, safety-control changes and validation activities.
- Identify the machinery or assembly affected, relevant standards and the records that must remain consistent.
Documentation does not replace the legal assessment. It does, however, give engineering, quality, procurement and compliance teams a common factual basis for selecting technical verification and assessing the next conformity steps.
A practical 2027 transition plan
20 January 2027 should not be treated as a last-minute paperwork date. Manufacturers, operators and integrators with an alteration pipeline can start by separating routine maintenance from projects that change functions, hazardous areas, safety logic or load-bearing structures. For higher-impact projects, check whether the original technical file is available and identify who will control the change history and validation evidence. Cross-border transfers, resale, integration projects and work split among contractors deserve particular attention.
The European Commission’s machinery page confirms that Regulation (EU) 2023/1230 applies on a mandatory basis from 20 January 2027. The operative wording is available in the current EUR-Lex consolidated text. Each case remains dependent on product scope, the actual modification and applicable law.
How Qianxin can support technical preparation
Within a written scope of work and verified capability, Qianxin can help teams identify relevant test standards, structure a validation plan and review technical-document consistency before testing. We do not determine legal manufacturer status or whether a change is substantial, act as a notified body, or guarantee a particular CE route or market-access result. Technical preparation and case-specific legal advice are often best progressed in parallel.
