EU MDR Labelling Requirements — What Non-EU Manufacturers Must Know

One of the most common reasons medical devices from non-EU manufacturers get stopped at EU customs is incorrect or incomplete labelling. It is also one of the most avoidable problems. EU MDR has very specific labelling requirements — and getting them wrong does not just delay your shipment, it can result in the entire batch being rejected or recalled.

This guide covers everything your label must include to comply with EU MDR 2017/745, the language requirements, UDI labelling obligations, and the mistakes that most commonly catch non-EU manufacturers by surprise.

Why EU MDR labelling is different from other markets

Many non-EU manufacturers assume that if their product is labelled correctly for the US FDA or another market, the EU label is similar enough. It is not. EU MDR has its own specific mandatory elements, its own symbology requirements, and critically — it requires your EU Authorized Representative's name and address on every label. This single missing element is responsible for a significant proportion of EU customs rejections of medical devices from non-EU countries.

Most common customs rejection reason: Missing EU Authorized Representative details on the label or packaging. If your product does not show the name and address of your EU AR, it will be stopped at the EU border regardless of how well the device itself complies with technical requirements.

Mandatory label elements under EU MDR

EU MDR Annex I, Chapter III specifies the information that must appear on the label of every medical device placed on the EU market. All of the following are mandatory:

Required on every EU MDR label

Manufacturer name and addressYour full company name and registered address — even as a non-EU manufacturer

EU Authorized Representative name and addressMandatory for all non-EU manufacturers — must be shown with the EC REP symbol

Device name or trade nameAs registered in EUDAMED

Batch/lot number or serial numberUsing the standardised LOT or SN symbols

UDI carrierUnique Device Identifier — barcode or RFID as required by your device class

Manufacturing date or expiry dateUsing standardised symbols — MFG for manufacture date, EXP for expiry

CE markFollowed by the four-digit identification number of the Notified Body if applicable

Sterility and single-use indicatorsWhere applicable — using standardised ISO 15223 symbols

Warnings and precautionsAny information needed for safe use, storage conditions, handling requirements

Instructions for use referenceOr full IFU if the device is not implantable and the IFU fits on the label

Language requirements

EU MDR requires that labelling information is provided in the official language of the member state where the device is sold. If you are selling across multiple EU countries, your label must include all required languages for those markets — or you must use separate country-specific labels.

Standardised symbols from ISO 15223 can replace text on the label where the symbol is universally understood, but any text that remains on the label must be in the local language. For most non-EU manufacturers selling EU-wide, this means either a multilingual label or a modular packaging system with language-specific inserts.

Practical approach for multi-country sales: Use ISO 15223 symbols wherever possible to reduce text — this minimises the number of language variants you need. Include text only where symbols are insufficient, and produce language-specific Instructions for Use inserts separately rather than printing all languages on the device label itself.

UDI labelling requirements

The Unique Device Identifier (UDI) system is one of the most significant labelling changes introduced by EU MDR. Every medical device placed on the EU market must carry a UDI carrier on the label — a barcode, QR code, or RFID tag that encodes the device identifier.

The UDI system has two components:

UDI-DI (Device Identifier) — identifies the specific version or model of your device. This is the static part.
UDI-PI (Production Identifier) — identifies the specific unit, including lot number, serial number, manufacturing date, or expiry date. This changes per batch.

The UDI-DI must be registered in EUDAMED before the device can be placed on the market. Your EU Authorized Representative handles this registration on your behalf.

The EC REP symbol — what it is and where it goes

The EC REP symbol followed by your EU Authorized Representative's full name, company name, and address must appear on every label. This is not optional and it is not acceptable to include it only in the Instructions for Use. It must be on the device label or primary packaging itself.

The 5 most common EU MDR labelling mistakes

Missing EU AR details — the single most common customs rejection reason for non-EU manufacturers
Using non-EU symbols — FDA symbols are not the same as ISO 15223 EU symbols. Using the wrong symbol is a compliance failure even if the meaning is identical
Missing UDI carrier — required for all Class I devices from May 2025 and all other classes from earlier deadlines
Wrong language — selling into Germany with only English labelling is a compliance failure even if the product is otherwise perfect
Outdated CE mark format — the CE mark must meet the minimum size requirements and must not be combined with any other marking that could cause confusion
