Beyond the CE Mark: What Changes for CNC Imports on 20 January 2027 — and What to Ask About Energy Now

Executive Summary

Snapshot

1 · The date that is missing from your quotation

Most machine tool quotations contain dozens of dates: order date, delivery window, payment milestones, warranty start. Almost none contain the one date that decides which law the machine is certified under, because the answer depends on when the machine is placed on the market or put into service — an event that happens months after the signature and is rarely written down.

Under Regulation (EU) 2023/1230, machinery placed on the market up to and including 19 January 2027 follows Directive 2006/42/EC. Machinery placed on the market from 20 January 2027 follows the Regulation. The cut-off is explicit and, as TÜV NORD and DGUV Test both state it, there is no period in which manufacturers may choose between the two texts. The Regulation was published in the Official Journal on 29 June 2023; a corrigendum published on 4 July 2023 moved the application date from 14 to 20 January 2027.

For a European buyer this matters in one specific way: a machine quoted in late 2026 with a normal lead time is likely to arrive under the new regime. If nobody has discussed which conformity path applies, the argument starts at commissioning, which is the worst possible moment to have it.

2 · What actually changes on 20 January 2027

The Regulation keeps the structure of essential health and safety requirements and adds substance in four places that are relevant to a CNC purchase.

Protection against external attack

Cybersecurity enters the essential requirements. A machine with remote service access, network connectivity or transferable programs now has to be assessed for the risk of external interference, not only for the mechanical hazards the old Directive covered.

Software, updates and integrity

Requirements on software safety and on the integrity and validation of updates are considerably more specific than under the Directive. For a buyer this is quietly important: a controller update that changes behaviour is now a conformity question, which means you should know in advance who is permitted to apply it and how it is documented.

Autonomous and AI-enabled functions

Safety requirements for autonomous systems and for AI systems used in safety functions are new, and where safety-related machine learning is involved a notified body is likely to be required. A conventional three-axis machining centre with no adaptive function is a different case from a cell with adaptive feed control; what matters is that the builder can tell you which requirements it assessed.

Documentation and economic operators

Digital operating instructions and digital declarations of conformity become permissible for professional users, while paper safety information remains required for non-professional use. Separately, the Regulation sets out the duties of manufacturers, authorised representatives, importers and distributors in its own articles, and non-EU manufacturers must have an economic operator established in the Union. If you import in your own name, some of those duties may be yours.

3 · From "saves power" to a number with a method

Energy has always been in the brochure and almost never in the comparison. The reason is simple: "low energy consumption" is an adjective, and adjectives do not survive contact with a spreadsheet. That is beginning to change, because there is now a method to hang the number on.

ISO 14955 is the International Organization for Standardization's first dedicated series on the environmental evaluation of machine tools. Developed by ISO/TC 39 and published between 2017 and 2020, it has five parts: Part 1 covers design methodology for energy-efficient machine tools, Part 2 the measurement of energy supplied to machine tools and their components, Part 3 the principles for testing metal-cutting machine tools with respect to energy efficiency, and Parts 4 and 5 the equivalent principles for metal-forming and laser processing machines and for woodworking machines.

The direction of travel is towards energy per output rather than power rating — the kWh consumed for a defined part and cycle, with the machine's auxiliary systems (coolant, compressed air, extraction, hydraulics) accounted for separately. That is the number a buyer can put next to an electricity tariff, and it is the reason the series matters more than any single "eco mode" feature.

Adoption is uneven, and that is the honest part. According to an analysis in Manufacturing Technology & Machine Tool, China adopted Part 1 as GB/T 40808.1-2021 (published 11 October 2021, in force 1 May 2022, identical to ISO 14955-1:2017), while Parts 2 and 3 were still at the draft-approval stage of adoption as of August 2025. In other words the design methodology is available internationally and in China; the agreed measurement methods for the machine as delivered are still catching up. Ask which part a supplier's figure was produced under.

Where functions are measured, they tend to be measured under stated conditions. A survey of energy-saving practice in the same journal records, for example, an idling-stop function on one Japanese builder's machines reported to cut energy by 74% when not cutting and 9% during cutting. Those are conditional results on specific machines, not a general specification — and that is exactly the point. A conditional number is usable. An unconditional one is not.

4 · China's side: two standards already in force

China has been building the same machinery from the standards side. The Industrial Mother Machine High-Quality Standards System Construction Plan set a target of no fewer than 300 standards formulated or revised by 2026, across six layers and 34 categories, and explicitly places green and low-carbon topics — energy saving, water saving, comprehensive resource use, green manufacturing evaluation, green design, green services, and carbon peak and neutrality — inside the basic and general layer. Separately, the Equipment Industry Development Centre of the Ministry of Industry and Information Technology listed "green manufacturing as a hard constraint" among its ten trends for intelligent machine tool transformation in 2026, noting that energy optimisation and carbon footprint tracking are becoming standard functions and that green indicators influence user selection.

The concrete instrument is JB/T 15087-2025, Green Design Product Evaluation Technical Specification — CNC Machine Tools. We verified it directly on the national standards information platform: published 2 July 2025, in force 1 February 2026, under the Ministry of Industry and Information Technology, developed by the national technical committee for metal-cutting machine tools with Hefei University of Technology, Beijing Machine Tool Research Institute, China National Institute of Standardization, Chongqing University, Chongqing Machine Tool Group, Wuhan Heavy Duty Machine Tool Group and Qiqihar No.2 Machine Tool among the drafting bodies. The standard sets out evaluation principles, methods and requirements together with how to prepare a product life cycle assessment report, and it combines indicator evaluation with life cycle evaluation across four attribute groups: resource, energy, environment and product.

Secondary summaries of the standard describe indicative baselines including a mass proportion of toxic and harmful substances below 8%, adoption of at least five energy-saving measures, a no-load noise sound pressure level of 81 dB(A) or less for machines up to 10 tonnes, and a remanufacturable parts proportion of at least 40%, with products that qualify able to use the green design product label under GB/T 32162-2015. We flag these as secondary — the full text is not freely available, so treat the numbers as indicative of the structure rather than as values you can hold a supplier to.

The useful consequence is not the certificate. It is that "green" now decomposes into questions you can ask: How loud is the machine at no load, measured how? What share of it can be remanufactured rather than scrapped? Which energy-saving measures are designed in, and what were they measured against? A related national standard, GB/T 40735-2021, covers evaluation of the inherent energy efficiency of CNC machine tools, and GB/T 28615-2012 gives guidance on remanufacturing metal-cutting machine tools.

One example of how partial published data usually is: Gree publishes an energy efficiency ratio of 4.0 or better for the chiller on its GA-LM540, alongside a ±0.1 °C coolant control figure. That is a genuine, checkable efficiency number — for one subsystem. We are not aware of Gree publishing a per-part energy figure for a complete machine. That gap is normal across the industry, and it is precisely why the question is worth asking in writing.

5 · A claim we could not verify, and why we are telling you

While checking the regulatory picture we repeatedly encountered a striking claim: that ISO had published, in May 2026, a technical report on life cycle carbon footprint calculation for CNC machine tools, and that verified carbon footprint declarations would be mandatory for machines placed on the EU market from 1 January 2027.

We could not confirm it. The claim appeared only on a single aggregator site, in several versions that disagree with one another on the publication date and on which ISO committee was responsible, and we found no matching entry in ISO's own catalogue. So we left it out of the analysis above and we would not advise anyone to plan around it.

We mention it because it is the most transferable thing in this report. Regulatory claims about 2027 are now circulating faster than the regulations themselves. The check is not difficult: ask for the exact standard or instrument number, the body that issued it, and the legal act that makes it mandatory — then look for it on that body's own site. A supplier or a newsletter that cannot produce all three has told you something useful.

6 · Twelve questions for your next RFQ

Conformity and documentation

1. Which conformity regime will this machine be declared under, and on what date is it expected to be placed on the market?
2. Is there an EU-type examination certificate or equivalent, what is its number, and when does it expire?
3. Who is the economic operator established in the Union, and who will hold the technical file and the declaration of conformity?
4. Which of the new requirements on cybersecurity, software integrity and update validation were assessed, and what was the conclusion?
5. If the machine has adaptive or AI-based functions, does that change the conformity path and does it require a notified body?
6. Will operating instructions and the declaration be supplied digitally, and in which languages?

Energy and environmental data

7. What is the energy per workpiece in kWh for a defined part and cycle, and which standard was it measured under (ISO 14955-2/-3, GB/T 40808.1, GB/T 40735, or an internal method)?
8. What is the idle power in kW, and what share of total energy do coolant, compressed air, hydraulics and extraction take?
9. What is the measured no-load noise level in dB(A), and at what machine mass or configuration?
10. Which energy-saving measures are designed in — and are they standard or optional, and is any of them switchable without affecting accuracy?
11. Is there a green design product evaluation against JB/T 15087-2025, and can the life cycle assessment report be seen?
12. What proportion of the machine is designed to be remanufactured, and are spare parts and remanufacturing services available in my market?

The point of these questions is not to collect certificates. It is to find out, before delivery, whether the supplier can answer them — because the ones who can tend to be the ones who have already done the work the 2027 date requires.

7 · Data Credibility Rating

8 · What this means if you buy or distribute machines

• Move the conformity question into the order. The regime that applies is decided by the placing-on-the-market date, which is decided by the delivery plan. Write the expected date and the regime into the contract and the ambiguity disappears.
• Treat documentation as a deliverable. Technical file, declaration of conformity, instructions in the right language, and a named holder. Machines do not fail because of missing paperwork; projects do.
• Convert energy into your own currency. Take kWh per part, multiply by your tariff and your annual volume, and compare. For many European shops the ten-year electricity line is comparable to a meaningful fraction of the purchase price.
• Do not over-read the cybersecurity and AI requirements. They apply to the functions a machine actually has. A connected cell with adaptive control is affected; a standalone machine is much less so. Asking which requirements were assessed tells you more than assuming.
• Decide deliberately who is the economic operator. For a distributor this is a service, not a formality: holding the technical file and being the contact point for authorities is exactly the role an established local partner should play, and it is worth asking who would do it if you bought direct.
• Check every "new rule" headline at source. One claim in this space failed our check this week. The habit costs five minutes.

9 · Limits of this analysis

• This is not legal advice and we are not a notified body. Conformity assessment decisions belong to the manufacturer and, where required, to a notified body. Use this as a list of questions, not as a determination.
• We are a Gree CNC distributor. We benefit from a narrative in which buying Chinese machine tools looks well-prepared rather than risky. Apply the same twelve questions to us, including the ones we cannot answer.
• Some sources are second-hand. The JB/T 15087 indicator baselines, the 300-standard plan and the MIIT ten trends come from summaries and media relays rather than the issuing bodies' own pages. They are labelled as such.
• The measurement gap is real. ISO 14955-2 and -3, the parts that say how to measure a delivered machine, were still being adopted in China as of August 2025. Until that is settled, per-part energy figures will come from mixed methods.
• Certificates and standards do not replace a run-off. A declaration of conformity says the machine met the essential requirements. It does not say it will hold tolerance on your part in your shop.
• Sometimes the right answer is to buy elsewhere. If you need a machine on the floor before the cut-off with no certification uncertainty, an EU-established supplier holding a current EU-type certificate is a rational choice — and if your work is regulated aerospace or medical process history, that consideration may outweigh everything on this page.
