One of the calls we get most often starts the same way: an importer whose shipment has been stopped because customs asked for the CE declaration of conformity, and what they have is a photo of the CE mark printed on the box. We understand the confusion, but the mark on the box and the document are two different things, and only one of them is what an inspector wants to see. The mark is the visible claim; the declaration is the written, signed commitment behind it. When the second one is missing or wrong, the first one means nothing.
So let us start from what an importer actually needs to know, rather than from a dictionary entry. The CE declaration of conformity is the manufacturer’s own statement, signed under their sole responsibility, that the product meets every applicable EU requirement and is entitled to carry the CE mark. No authority issues it. No laboratory stamps it for you. It is a self-declaration, supported by technical documentation, and in higher-risk categories by a prior assessment from a Notified Body. That last distinction is where a lot of importers we work with assume far more comfort than the paper actually gives them.
Where the CE declaration of conformity comes from
The structure of the document is not improvised. It descends from Decision No 768/2008/EC, the text that built the New Legislative Framework and standardised both the conformity assessment modules and the model declaration that nearly every CE law adopted afterwards reuses. Why does that matter to you as an importer? Because once you have read one declaration properly, you can read almost any of them: a machine, a radio transmitter, a low-voltage power supply or a toy all follow the same backbone, even though each sector adds its own annex on top.
The sector layer is where precision starts to count. Take medical devices: Article 19 of Regulation (EU) 2017/745 spells out exactly what the declaration must carry, down to the Basic UDI-DI and the specific Annex of the assessment route followed. In vitro diagnostics answer to their own regulation. A pressure cooker answers to the Low Voltage and Machinery rules instead. There is no single template that fits everything, and in our experience the most expensive mistakes come from importers who reused a friendly-looking declaration from one product line on another that the law treats completely differently.
What a usable CE declaration of conformity actually contains
Whatever the sector, a declaration that survives an inspection identifies the product without ambiguity, names the manufacturer with a registered address, and adds the EU authorised representative when the manufacturer sits outside the Union. It lists every directive and regulation that applies, the harmonised standards used, and, where a Notified Body intervened, that body’s number and the certificate it issued.
We have seen far more declarations fail on small details than on big ones. The signatory must appear by name and position, not as an unreadable scrawl at the bottom of the page; a signature with no printed name is, strictly, non-compliant. Citing a regulation number while staying silent on which assessment route was followed is another gap that surveillance authorities now pick up almost reflexively. None of this is exotic. It is the part everyone assumes the factory got right, and the part the factory most often did not.
What the law puts on the importer, not the maker
Here is the point most factories will never explain to you, because it is not their problem. The duties attached to the CE declaration of conformity do not end when the supplier emails you a PDF. You are required to verify, before the goods reach the market, that the declaration exists, that it covers the exact model in the container, that the legislation cited is the right one, and that any Notified Body named still holds a live certificate for that category. A certificate that lapsed last quarter is a declaration resting on nothing.
Then you have to keep it. Ten years for medical devices, and as a rule ten years across the other CE regimes, available to market surveillance authorities whenever they ask. And if you find out, after the product is already selling, that the CE declaration of conformity was invalid, the obligation flips into action: tell the manufacturer, tell the competent authority (AEMPS, in Spain, for medical devices) and cooperate with whatever corrective measure or recall follows. An importer who keeps selling while knowing the declaration is broken is treated by EU law as the manufacturer, with the liability to match.
When you stop being only the importer
There is a line you can cross without meaning to. Put the product on the market under your own brand, or change it in a way that touches its compliance, and the law stops seeing you as an importer and starts seeing you as the manufacturer, declaration and all. Adding your name beside the original maker’s is usually fine. Erasing theirs is not. Reworking the intended purpose, opening a sterile barrier, or modifying the software of a device pushes you over the same edge. We have watched this clause turn a routine private-label project into a full conformity assessment from scratch, so it is worth a conversation before, not after, you tell the factory to drop their logo.
The factory sent me a photo of the CE mark. Is that enough?
No. The mark on the box is a claim; the declaration is the signed document behind it, and customs and market surveillance want the document. Ask for the full CE declaration of conformity as a signed file, then check it against the model you are actually importing.
If you would rather not guess whether a supplier’s paperwork holds up, that is exactly the review we do at ASC Services. We read the declaration, line it up against the right legislation and tell you where you stand as the importer.
