CE marking for U.S. machine builders

Your European customer asked for “the CE certificate.” There isn’t one — and that is the first thing worth understanding, because everything else follows from it.

CE marking is not a certificate you buy. It is a declaration you make, backed by a file you assemble, carrying liability you hold. For most machinery there is no third party involved at all. That is either very good news or very bad news, depending on whether anyone has told you before the machine shipped.

We can tell you which parts of your existing U.S. compliance work transfer, and which parts have to be done again.

What CE marking actually requires

Four things, in this order. Skip any of them and the marking is not valid, whatever is stamped on the machine.

  1. 1.Identify every directive that applies. Almost every machine falls under the Machinery Directive. Many fall under two or three more at the same time — electromagnetic compatibility, pressure equipment, explosive atmospheres. Each one you miss is a hole in the declaration you are about to sign.
  2. 2.Run a risk assessment, and design against it. This is the part that cannot be retrofitted cheaply. It is not a form; it is the engineering record of every hazard you identified and every measure you took. In a dispute it is the first document anyone asks for.
  3. 3.Assemble the technical file before the machine goes on the market. Not after. Not “we could put it together if asked.” Before.
  4. 4.Sign the EU Declaration of Conformity and affix the mark. You sign it. Not us, not a laboratory, not your distributor.

Do you need a Notified Body? Usually not

This is the single most expensive misunderstanding in the market, and it runs in both directions: some manufacturers pay for third-party assessment they never needed, and others discover far too late that they did.

The rule under the Machinery Directive in force today:

  • Your machine Not in Annex IV — most industrial machinery What you need Self-assessment. No Notified Body
  • Your machine In Annex IV, built fully to harmonised standards covering all the relevant requirements What you need Self-assessment is still allowed
  • Your machine In Annex IV, not built fully to those standards What you need Notified Body: EC type-examination, or a full quality assurance system

Read the middle row again — it is the one that is almost always reported wrong.

Fact — check it yourself

Being on the Annex IV list does not, by itself, force you to a Notified Body.

Directive 2006/42/EC, art. 12(3)(a)

This changes on 20 January 2027. Under the new Machinery Regulation, six categories move to a list where third-party assessment is mandatory regardless of which standards you built to. If your machine is in one of them, self-assessment stops being an option.

20 January 2027: the deadline that is already in your quotes

On that date the Machinery Directive is repealed and Regulation (EU) 2023/1230 applies. There is no overlap and no grandfathering for new machines. What decides which rules apply is the date the machine is placed on the EU market — not when you designed it, not when the order was signed.

A machine you are quoting today for 2027 delivery is a Regulation machine. The design decisions that determine whether it complies are being made right now.

One detail that tells you who has actually read the law.

Fact — check it yourself

The version published in the Official Journal says 14 January 2027.

That was a clerical error, corrected to 20 January by a corrigendum issued days later. The uncorrected date is still circulating — including in files served today from the EU’s own legislation portal.

If a supplier or a compliance checklist tells you 14 January, they are working from a superseded text, and it is worth asking what else they have not checked.

“Our panel is UL 508A listed” — what transfers and what doesn’t

Nothing transfers automatically. That is the short answer, and it surprises people who have built a genuinely excellent panel.

Europe asks a different set of questions about the electrical equipment of a machine, and answers them through EN 60204-1. A UL 508A listing is not evidence of conformity with it. The delta is a defined engineering task — short-circuit withstand demonstrated differently, disconnecting means, protective bonding, conductor identification, and a specific documentation set inside the technical file — but it is a task, and it has to be done before the machine ships, not after an inspector raises it.

Part of that task is analysis and part of it is hardware, and telling the two apart is the first job of the project. It matters commercially, not just technically: the analysis half is often mistaken for the hardware half, and a panel gets rebuilt when a calculation would have done.

This is the part where working with an engineering firm that operates on both sides is worth something concrete: we can tell you which of your existing drawings and test reports are reusable evidence and which are not, instead of starting the file from a blank page.

The directives we work in

Machinery — the Directive today, the Regulation from 2027. Risk assessment, user manuals, PL/SIL analysis, robotics and collaborative robotics, cybersecurity risk assessment, EC/EU type-examination support, substantial modification.

ATEX — Directive 2014/34/EU for equipment in potentially explosive atmospheres, and Directive 1999/92/EC for the workplace and area classification. Hazardous area classification for zones 0, 1, 2 and 20, 21, 22; equipment selection; risk assessment; Notified Body interface.

Pressure equipment — Directive 2014/68/EU. Classification by pressure, volume, fluid group and risk category; conformity assessment modules; design verification; Notified Body interface.

Functional safety — IEC 61508 as the generic framework, and for machinery the two harmonised routes: EN ISO 13849, based on Performance Levels, and EN 62061, based on Safety Integrity Levels and better suited to electrical, electronic and programmable electronic systems. Which one fits your architecture is a decision worth making at design stage, not at validation.

If you have no company in Europe, you need someone who does

A machine may be placed on the EU market only if there is an economic operator established in the Union responsible for a defined set of duties: keeping the Declaration of Conformity available to authorities, making sure the technical documentation can be produced on request, answering reasoned requests in a language the authority understands, and cooperating on corrective action.

That operator can be an EU manufacturer, an importer, an authorised representative with a written mandate, or an EU fulfilment service provider. If you sell direct, or through more than one channel, it should be an authorised representative — and their name and contact details must appear on the product, its packaging, the parcel or an accompanying document.

Fact — check it yourself

This requirement is not limited to machinery.

It applies to ATEX equipment and pressure equipment too, which is why it catches manufacturers who assumed it was a machinery-only formality.

How we work

We start from what exists. Send us drawings, an existing risk assessment, a manual, a UL file — whatever you have. The first deliverable is a gap list, not an invoice for starting from zero.

We tell you the route before you commit. Annex IV or not. Notified Body or not. Directive or Regulation. Those three answers determine your cost and your schedule, and you should have them before you sign anything.

You keep the signature, and the control. We build the file and the evidence. The Declaration is signed by you, because the law puts the responsibility on the manufacturer.

One relationship, both directions. European entity, U.S. entity, same engineers.

Common questions

Tell us the machine and the destination market. We will come back with the route — which directives apply, whether a Notified Body is in the loop, and what you already have that counts as evidence.
