Europe's Device Register Went Live in May. Whether You Had to Be On It Depends on Who You Bought the Frames From.

On 28 May 2026, four modules of EUDAMED — the European database on medical devices — stopped being voluntary. Frames, spectacle lenses, ready-to-wear readers and contact lenses are medical devices under the EU Medical Device Regulation, so this is an optical story even though almost nothing written about it mentions eyewear. It is now four months later, and the part most stores have missed is not the database. It is that whether you had to be in it at all turns on a question that has nothing to do with your products, your size, your turnover or your country. It turns on who you bought the frames from.

Buy a pallet of frames from a wholesaler in Italy and you are a distributor. Buy the identical pallet from the factory in Shenzhen that made them, and you are an importer. Same frames, same warehouse, same customers, same invoice value. Different legal person, different duties, and one of them was supposed to be registered with Brussels before it sold its first pair.

What actually happened on 28 May, and the one-sentence reason it is not a proposal

EUDAMED has been "coming" for years, which is why the trade press stopped reporting it. The thing that changed is procedural and it is worth understanding, because it is the same mechanism that will switch on the remaining modules.

Regulation (EU) 2024/1860 rewrote Article 123(3) of the Medical Device Regulation so that the database's obligations are triggered not by a date in the legislation but by a notice. The replaced point (d) reads that the obligations relating to the electronic systems "shall apply from the date corresponding to 6 months from the date of publication of the notice referred to in Article 34(3), informing that the relevant electronic system is functional".

The Commission published that notice — Commission Decision (EU) 2025/2371 of 26 November 2025 — in the Official Journal on 27 November 2025, declaring four modules functional: Actor registration, UDI/Device registration, Notified Bodies and Certificates, and Market Surveillance. Six months later is 28 May 2026, and that is the date the Commission itself publishes as the mandatory-use date.

There was no vote, no transposition and no national implementing measure. A decision was published, and six months of clock ran out. If you are wondering why nobody sent you a letter: nobody sends letters. This is the same pattern we wrote about when a delegated act rewrote the scope of the deforestation regulation without anyone sitting in a chamber.

The line is drawn by where you bought it

The Medical Device Regulation defines the two roles in consecutive sentences, and the whole of this post hangs on the difference between them.

"'importer' means any natural or legal person established within the Union that places a device from a third country on the Union market"

"'distributor' means any natural or legal person in the supply chain, other than the manufacturer or the importer, that makes a device available on the market, up until the point of putting into service"

Note what is absent from both. There is no threshold. No turnover test, no unit count, no exemption for a store that sells forty pairs a month, no carve-out for online-only. The distinction is a single fact about the supply chain: did the goods come to the Union market through you, or had somebody already brought them in?

For an ordinary optical retailer this is not academic. A shop that buys house-brand acetate frames direct from a manufacturer in China is an importer of medical devices. A shop that buys the same frames through a European agent or distributor is not. Most stores of any size do both, for different lines, which means most stores are an importer for part of the catalogue and a distributor for the rest — and the duties attach line by line, not company-wide.

If you are the importer

The Commission's own EUDAMED guidance states the registration duty in plain terms:

"Every economic operator (EU and non-EU manufacturers, authorised representatives, system/procedure pack producers and importers) must register as an actor in EUDAMED before placing devices or Systems/Procedure Packs in the EU market."

Importers are on the list. Distributors are not. Registration is made to your national competent authority through EUDAMED, and once it is approved the system issues a Single Registration Number — an SRN — which is the identifier that follows you through the rest of the machinery. Since 28 May 2026 that registration is a precondition of placing devices on the market, not a nice-to-have.

The verification duty came first and is easy to fail quietly. Article 13(1) is one line: "Importers shall place on the Union market only devices that are in conformity with this Regulation." Article 13(2) then requires that, before placing a device on the market, importers verify all of the following:

"(a) the device has been CE marked and that the EU declaration of conformity of the device has been drawn up; (b) a manufacturer is identified and that an authorised representative in accordance with Article 11 has been designated by the manufacturer; (c) the device is labelled in accordance with this Regulation and accompanied by the required instructions for use; (d) where applicable, a UDI has been assigned by the manufacturer in accordance with Article 27."

Point (b) is the one that catches direct buyers. A manufacturer outside the Union must have designated an EU authorised representative. If your Shenzhen supplier has not, you cannot lawfully place the device on the market, and the practical consequence is that you either get them to appoint one or you stop buying direct.

Then Article 13(3), which is the duty with the most visible consequence:

"Importers shall indicate on the device or on its packaging or in a document accompanying the device their name, registered trade name or registered trade mark, their registered place of business and the address at which they can be contacted, so that their location can be established."

Your name goes on the box. Not the manufacturer's — yours, in addition. For a store that has spent money making its packaging look like the brand's packaging, this is an unwelcome sentence, and it is not optional.

If you are only a distributor, you are not off the hook — you are the checker

Article 14(2) gives distributors a verification duty of their own, and its third limb is the interesting one:

"Before making a device available on the market, distributors shall verify that all of the following requirements are met: (a) the device has been CE marked and that the EU declaration of conformity of the device has been drawn up; (b) the device is accompanied by the information to be supplied by the manufacturer in accordance with Article 10(11); (c) for imported devices, the importer has complied with the requirements set out in Article 13(3); (d) that, where applicable, a UDI has been assigned by the manufacturer."

Point (c) means that a European retailer buying imported frames from a European wholesaler must check that somebody else's name and address appear on the device, its packaging or an accompanying document. If no importer is identified anywhere in the chain on goods that plainly came from outside the Union, that is a finding about your supplier — and, once you have made the device available anyway, a finding about you.

This is the mirror image of the duty we described for connected eyewear under the Cyber Resilience Act, where distributors likewise have to verify upstream conformity rather than merely pass the box along.

The three things that turn a retailer into a manufacturer

Everything above assumes you resell devices as they arrive. Article 16(1) sets out when you stop being a reseller in the eyes of the Regulation:

"A distributor, importer or other natural or legal person shall assume the obligations incumbent on manufacturers if it does any of the following: (a) makes available on the market a device under its name, registered trade name or registered trade mark, except in cases where a distributor or importer enters into an agreement with a manufacturer whereby the manufacturer is identified as such on the label and is responsible for meeting the requirements placed on manufacturers in this Regulation; (b) changes the intended purpose of a device already placed on the market or put into service; (c) modifies a device already placed on the market or put into service in such a way that compliance with the applicable requirements may be affected."

"The first subparagraph shall not apply to any person who, while not considered a manufacturer as defined in point (30) of Article 2, assembles or adapts for an individual patient a device already on the market without changing its intended purpose."

Limb (a) is the private-label trap, and it has an exit written into it: an agreement under which the manufacturer is identified on the label and keeps the manufacturer's obligations. If you sell house-brand frames and you do not have that agreement in writing, the default position is that you are the manufacturer of them. Limb (c) is the glazing question we set out at length when Meta started selling smart glasses through opticians — and the final subparagraph is the carve-out that a dispensing optician relies on, which is drafted around adaptation "for an individual patient", not around fitting lenses generally.

The consequences of falling into Article 16 are not administrative. A manufacturer registers devices, not just itself; holds the technical documentation; signs the declaration of conformity; and under Article 10(15) must have liability cover proportionate to risk class and enterprise size. It also changes who the injured customer sues, which is the subject we covered in the new Product Liability Directive.

The duty nobody expects: relabelling, repackaging, and 28 days' notice

Article 16(2) says two ordinary retail activities are not modifications that make you a manufacturer: providing or translating the manufacturer's information, and

"changes to the outer packaging of a device already placed on the market, including a change of pack size, if the repackaging is necessary in order to market the device in the relevant Member State and if it is carried out in such conditions that the original condition of the device cannot be affected by it"

That is the relief. Article 16(3) and 16(4) are the price of it. A distributor or importer doing either of those things must indicate on the device or packaging what it did and who it is, must operate a quality management system covering the accuracy of the translation and the integrity of the repackaging, and:

"At least 28 days prior to making the relabelled or repackaged device available on the market, distributors or importers carrying out any of the activities mentioned in points (a) and (b) of paragraph 2 shall inform the manufacturer and the competent authority of the Member State in which they plan to make the device available of the intention to make the relabelled or repackaged device available"

— and must supply, on request, a certificate from a notified body attesting that the quality management system complies. Twenty-eight days' notice to a national authority, plus a notified body certificate, in order to translate an instruction leaflet into Dutch. That is what this Regulation does on an ordinary Tuesday, and it is why the sensible course for most stores is to have the manufacturer supply the market-ready pack rather than to build one yourself.

Two dates still ahead, and one of them is in your Q4

9 November 2026 — contact lenses. Commission Delegated Regulation (EU) 2023/2197 introduced the Master UDI-DI for contact lenses: instead of a separate identifier for every power, a single identifier covers lenses sharing design parameters including at least base curve and diameter. It was written to apply from 9 November 2025, and that is still what the act's own final article says if you read the original. It is wrong. Commission Delegated Regulation (EU) 2025/788 of 16 April 2025 replaced the second paragraph of that article with a single sentence: "It shall apply from 9 November 2026." The obligation falls on manufacturers, not on you — but it lands in the middle of the fourth quarter, and relabelled stock, changed barcodes and re-pointed catalogue data are a retail problem whoever owes the duty.

28 November 2026 — devices already on the shelf. Article 123(3)(e), as replaced by Regulation (EU) 2024/1860, gives twelve months from the same notice: "no later than 12 months from the date of publication of the notice referred to in Article 34(3) … manufacturers shall ensure that the information to be entered in Eudamed in accordance with Article 29 is entered in that electronic system." Twelve months from 27 November 2025, counted the way the Commission itself counted the six-month period to reach 28 May 2026, is 28 November 2026. Devices placed on the market before 28 May 2026 that continue to be sold afterwards have to be in the UDI/Device module by then.

The operative sentence says "manufacturers". Read strictly, this is not your filing. It is still your commercial problem: after that date, a line you stock whose manufacturer has not registered it is a line with no EUDAMED record behind it, and your own Article 13(2) and 14(2) verifications get harder to answer honestly.

And a date that is not in 2026 at all. The Master UDI-DI for spectacle frames, spectacle lenses and ready-to-wear reading spectacles comes from Commission Delegated Regulation (EU) 2025/1920 of 12 June 2025, which adds new sections to Part C of Annex VI of the MDR, and it applies from 1 November 2028. The accompanying guidance, MDCG 2025-8, is explicit that spectacles produced before that date are not required to carry it. If a supplier or consultant is invoicing you for spectacle Master UDI-DI readiness as a 2026 emergency, check that date.

What we are deliberately not asserting

• Whether a dropshipper is an importer. The definition catches a person "established within the Union that places a device from a third country on the Union market". Where a third-country supplier ships direct to the customer and the customer is the declarant, who "places" the device is genuinely contested, and we found no guidance addressing it for devices. This matters enormously to small optical stores and we are not going to invent an answer. It sits alongside the customs-side questions in our piece on the end of the €150 exemption.
• Whether putting frames into your own gift box is Article 16(2)(b) repackaging. The carve-out is conditioned on the repackaging being "necessary in order to market the device in the relevant Member State". A presentation box chosen for brand reasons is not obviously necessary. No guidance found either way.
• 27 or 28 November 2026. At least one well-regarded practitioner guide gives 27 November as the conservative reading of the twelve-month period. We think 28 November follows from the Commission's own counting of the six-month period, but the difference is one day and the sensible course is to be finished before the 27th.
• Whether the 28 November duty reaches importers. A widely read law-firm note describes it as falling on "manufacturers and importers". The operative sentence names manufacturers. If you are also the manufacturer under Article 16, it is yours; otherwise treat it as your supplier's deadline and your supply risk.
• The exact wording of Article 31. We were unable to render the text of the MDR's registration article from the Official Journal in this pass — the consolidated text truncates before it. The registration duty stated above is taken from the Commission's own EUDAMED guidance, quoted verbatim, and not from the article text. Check the article before relying on its precise terms.
• Any small-business exemption. We looked and found none in the importer, distributor or registration provisions. Absence of a finding is not proof of absence.

What to actually do this quarter

1. Split your catalogue in two. For every line, write down whether the goods entered the Union through you or through someone else. That single column decides which set of duties applies, and nobody can do it for you.
2. For anything in the "through us" column, check whether you have an SRN. If you have never heard of one, you do not have one, and the registration was due on 28 May 2026. Register with your national competent authority through EUDAMED.
3. Ask every third-country supplier for their EU authorised representative. Article 13(2)(b) makes their answer your problem. No authorised representative, no lawful placing on the market.
4. Look at a box. Physically. If you are the importer, your name, registered place of business and contact address must be on the device, the packaging or an accompanying document. If you are the distributor of imported goods, somebody's must be.
5. Find out, in writing, whether you are the manufacturer of your house brand. Article 16(1)(a) makes you one by default unless there is an agreement identifying the actual manufacturer on the label and keeping the obligations with them. Ask your supplier for that agreement before the question is asked by somebody else. The classification of the object is a theme we keep returning to — it decided the outcome in our piece on which eyewear counts as a medical device, and it decides this one too.
6. Stop translating leaflets yourself unless you mean it. If you are relabelling or repackaging, Articles 16(3) and 16(4) want a quality management system, 28 days' notice to a competent authority and a notified body certificate. Ask the manufacturer to supply market-ready packs instead.
7. Diary 9 November and 28 November 2026. The first is when contact lens Master UDI-DIs become mandatory for your suppliers. The second is when devices already on the shelf need a EUDAMED record.

The frames do not change. The law does not change. You change, in the eyes of the Regulation, when you buy the same thing from a different address.

This article is general information about European Union medical device law and is not legal advice. It does not describe VisioncarePro's own regulatory status. The Medical Device Regulation's registration timetable is driven by Commission notices and delegated acts that can move without a legislative procedure — the contact lens date in this article was itself moved by one year by a later delegated act — and national competent authorities differ in how they register and supervise economic operators. Check your own position with a qualified adviser and with your national authority.
