CE Marking Labeling Requirements For Medical Devices In The Eu

1. Decide which CE-label rule applies before printing

Use intended purpose, manufacturer, risk class, sterile/measuring/reusable-surgical status, supply route and legacy status as the starting inputs. A box-ticking label cannot cure an incorrect legal classification.

An MDR device needs its valid conformity route completed before CE is affixed for market placement (MDR Articles 19, 20 and 52). For a fuller route sequence, see the MDR CE-marking process; this page owns the label-release decision.

2. CE mark: position, artwork and notified-body number

Under MDR Article 20(3), place the CE marking visibly, legibly and indelibly on the device or its sterile packaging; if that is impossible or unjustified because of the device’s nature, use its packaging. CE must also appear in any instructions for use and on sales packaging. Apply it before placing the device on the market.

Use the official Annex V proportions: the components must have substantially the same vertical dimension, generally at least 5 mm; Annex V allows the minimum to be waived for small-scale devices. Do not improvise a text-font “CE”, stretch the proportions, or assume every small label automatically qualifies for the waiver.

Where a notified body is responsible for the Article 52 conformity assessment, put its identification number after the CE mark; Article 20(5) also applies to promotional materials mentioning CE compliance. The number is not the manufacturer’s registration number, a UDI or a certification logo. A CE mark does not replace the signed EU declaration of conformity.

3. Annex I label-content matrix: what must be visible

Apply MDR Annex I, Chapter III, points 23.1–23.3 to each device and packaging layer. The first location for required label information is the device itself; when impracticable or inappropriate, some or all may appear on unit or multiple-device packaging. “Where applicable” items require a recorded reason, not automatic omission.

A packaging mock-up is not sufficient evidence on its own: match each claim, symbol, warning and intended-use statement to the risk file, device identification and technical documentation (MDR Annex II). Recognised symbols may be used under 23.1(h), but standards such as EN ISO 15223-1 support implementation; they do not replace the binding Regulation.

4. UDI is a separate carrier obligation — check the calendar

For newly MDR-compliant devices, a UDI generally includes UDI-DI and UDI-PI; its carrier goes on the device label and higher packaging levels, excluding shipping containers (Article 27; Annex VI Part C). The Basic UDI-DI is an identifier for regulatory documentation/database grouping, not the label barcode itself.

These dates concern MDR carrier placement, not a blanket requirement to re-label all eligible legacy devices. Annex VI Part C has specific exceptions for space-constrained unit packaging, individually packaged single-use class I/IIa devices and direct marking where unsafe or technologically infeasible. Record the applicable exception. Since 28 May 2026, EUDAMED’s UDI/Devices module is mandatory under the staged roll-out; database registration and a physical UDI carrier are different checks.

For a device model first placed on the EU market on or after 28 May 2026, check EUDAMED registration before that first placement. Under MDR Article 123(3)(e), as amended by Regulation (EU) 2024/1860, qualifying models first placed earlier but still being placed on the market after mandatory use began have a separate 12-month registration window. Check the precise conditions and applicable deadline; this database obligation neither replaces the physical UDI carrier nor automatically requires re-labelling eligible legacy devices.

The 12-month period is counted from publication of the functionality notice on 27 November 2025, not from the 28 May 2026 mandatory-use date. The Commission’s transition infographic indicates 28 November 2026 for qualifying continuing models; verify the applicable legal end date and whether the specific device meets the transition conditions before relying on that date.

5. Instructions, languages, symbols and electronic delivery

Annex I 23.4 defines IFU content, including intended purpose, users, contraindications, warnings, performance, preparation/reprocessing, incidents and revision identification as applicable. Exceptionally, an IFU may be omitted for class I and IIa devices safe to use without it, unless another rule requires one (23.1(d)). Article 10(11) requires information in the official EU language(s) determined by each destination Member State; check each market rather than assuming English works EU-wide.

Under Implementing Regulation (EU) 2021/2226 as amended by 2025/1234, eIFU instead of paper may be used for eligible devices intended for professional users, subject to a documented risk assessment, accessibility and the Regulation’s other conditions, including paper availability on request. Where lay use is reasonably foreseeable, the lay-user IFU must be supplied on paper. Software has a specific eIFU rule. A QR code alone does not waive label, language or IFU duties.

When electronic instructions replace paper, Article 6 of Implementing Regulation 2021/2226 separately requires a clear notice on the unit packaging (or, where appropriate, sales packaging) that the IFU is electronic and information on how to access it. If access details cannot practicably be placed there, provide them in a paper document with every device. Software has a specific placement rule at its access point. A QR code without the legally required notice and access information is insufficient.

If eligible eIFU replaces paper, the manufacturer must offer paper instructions free of additional charge, within the period justified in the eIFU risk assessment and no later than seven calendar days after the request, or upon device delivery if requested when ordering (Implementing Regulation 2021/2226, Article 5(3)).

6. Practical label-release evidence pack (manufacturer / importer / distributor)

Treat this as a release gate for each SKU, packaging level, destination language and label revision:

1. Approved intended purpose, MDR/IVDR determination, Annex VIII class and Article 52 route; recorded legacy/custom-made exception if claimed.
2. Signed EU declaration of conformity and applicable notified-body certificate/scope; CE artwork and correct four-digit notified-body identification where needed.
3. Controlled drawings/photos of device, sales pack, sterile barrier and IFU, with point-by-point Annex I 23.2–23.4 mapping and rationale for omissions.
4. UDI-DI/UDI-PI and package hierarchy, issuing-entity evidence, scan/legibility results, direct-marking assessment, Basic UDI-DI and applicable EUDAMED record.
5. Country-by-country translation approval, symbol meanings, controlled IFU version, eIFU risk analysis if used, and warnings aligned to the risk file.
6. Importer name/contact presentation, Article 13/14 verification, label-change approval, traceability and documented review after design, claims or operator changes.

The manufacturer owns the device information and conformity. An importer must verify CE, declaration, authorised representative, labels/IFU and applicable UDI; its name and contact address may be on the device, packaging or accompanying document (Article 13(3)). Distributors verify the Article 14 items. Translating or relabelling by an importer/distributor can trigger Article 16 conditions; do not cover original information with an additional label.

7. Exception and failure-mode decisions that stop release

Hold release if the CE mark is missing from a required location, the notified-body number is wrong or absent, no applicable conformity evidence exists, the manufacturer/representative is misidentified, a required warning/language/UDI carrier is missing, or a sterile barrier has an incomplete statement. Correct the deficiency and document re-approval; a declaration, barcode or catalogue listing cannot substitute for a missing label duty.

Check special paths: a compliant Article 22 system/procedure pack generally has no additional CE mark on the pack itself; if incompatible/non-CE components change its legal status, the pack may require device conformity assessment. Custom-made and investigational devices are not ordinary CE sales devices. Implantables may require an Article 18 implant card. Changing intended use, sterilisation, manufacturer/representative, warnings or package configuration requires a fresh assessment of affected artwork, technical documentation and any notified-body involvement.

For an Article 22-compliant system or procedure pack, the absence of an additional CE mark on the pack does not waive other duties: identify the person assembling the pack and their contact address, supply the prescribed user information, and assign the pack its own UDI under Annex VI Part C, point 6.3. Check the separate UDI carrier rules for its component devices.

Device-specific questions

Can I put the CE mark only on the outer carton?

Not as a default. Article 20(3) prioritises the device or sterile packaging; only where this is impossible or unjustified by the device’s nature may packaging be used. CE also belongs on sales packaging and any IFU.

Does a class I sterile product need CE plus four digits?

Not for every class I device, but class I sterile status triggers notified-body involvement limited to the relevant sterility aspects under Article 52(7). Verify the applicable assessment and follow Article 20(5) for the notified-body number.

Is an EU importer required to print its details on the original manufacturer label?

No single placement is compulsory: Article 13(3) permits the device, its packaging or an accompanying document, without hiding the manufacturer’s original label.

Can I replace the paper IFU with a QR code for home users?

Not on that basis. Professional-use eIFU is conditional under amended Regulation 2021/2226; reasonably foreseeable lay use requires paper instructions for those lay users.

Does the Basic UDI-DI go in the printed UDI barcode?

No. The carrier encodes UDI-DI/UDI-PI; Basic UDI-DI principally connects EU documentation and registration. Check Annex VI packaging and human-readable/AIDC requirements.
