Medical Device Labelling Regulatory Requirements
Regulators require manufacturers to ensure that device labels and instructions for use provide clear, accurate information that supports safe and effective use. Labelling also plays a key role in traceability, post-market surveillance, and regulatory compliance.
Under the European Union Medical Device Regulation, detailed labelling requirements are defined in Annex I of Regulation (EU) 2017/745. The full regulation can be reviewed through the official EU legal text for the EU MDR Regulation (EU) 2017/745.
In the United Kingdom, similar requirements apply under the UK medical device regulatory framework overseen by the Medicines and Healthcare products Regulatory Agency. Guidance on these requirements can be found on the UK government page for UK medical device regulations.
In the United States, medical device labelling is governed primarily by 21 CFR Part 801, which establishes labelling requirements for devices regulated by the Food and Drug Administration. The regulation is available through the FDA regulations portal for 21 CFR Part 801 Medical Device Labelling.
Understanding how these regulatory frameworks align is essential for manufacturers operating in global markets.

This article focuses on medical device labelling requirements under the EU MDR. If you're looking for a complete overview of the Medical Device Regulation, including classification, GSPRs, technical documentation, UDI, CE marking and post-market obligations, read our Complete Guide to the EU MDR.
What is medical device labelling?
Medical device labelling refers to the information provided with a device that identifies the product, explains its intended use, and provides instructions for safe operation.
Labelling may include several elements:
- product labels attached to the device or packaging
- instructions for use
- regulatory markings
- safety warnings and precautions
- traceability information such as Unique Device Identification codes
The EU MDR outlines general labelling expectations within Annex I of the regulation, which can be reviewed in the official EU MDR regulatory text.
The goal of labelling is to ensure that users, healthcare professionals, and regulators have the information needed to safely identify and operate the device.
EU MDR labelling requirements
Under the EU MDR, labelling requirements are defined within Annex I General Safety and Performance Requirements.
These requirements ensure that devices are accompanied by clear and comprehensive information.
Key EU MDR labelling elements typically include:
- device name and manufacturer details
- CE marking
- device model or catalogue number
- intended purpose
- storage and handling conditions
- warnings and precautions
- Unique Device Identification information
Manufacturers must ensure that labelling information is consistent with the device’s technical documentation and intended use.
Further guidance on MDR implementation can be found on the European Commission medical device resources page for MDCG guidance documents.
UK Medical device labelling requirements
Following Brexit, the United Kingdom introduced its own regulatory framework for medical devices.
Devices placed on the Great Britain market must typically carry the UKCA mark, demonstrating conformity with UK medical device regulations.
Guidance for manufacturers can be found on the UK government page for medical device conformity assessment and UKCA marking.
UK labelling requirements generally mirror many EU MDR principles but require specific UK regulatory identifiers.
Common UK label elements include:
- UKCA mark
- manufacturer information
- UK Responsible Person information for overseas manufacturers
- device identification information
- instructions for use and safety warnings
Manufacturers selling devices in both the EU and UK markets must ensure that labelling satisfies both regulatory frameworks.
FDA medical device labelling requirements
In the United States, medical device labelling requirements are defined in 21 CFR Part 801.
The FDA regulation outlines requirements for:
- device identification
- intended use statements
- warnings and precautions
- manufacturer information
- directions for use
The full regulatory text can be reviewed in the US Code of Federal Regulations for 21 CFR Part 801.
FDA labelling requirements also include Unique Device Identification (UDI) rules, which improve traceability across the device lifecycle.
Manufacturers must ensure that UDI information appears on device labels and is submitted to the FDA’s Global Unique Device Identification Database.
Unique Device Identification (UDI) requirements
UDI systems improve device traceability across supply chains and healthcare systems.
The EU MDR introduced mandatory UDI requirements for most devices, requiring manufacturers to assign a unique identifier to each device model and production batch.
UDI requirements in the United States are defined by FDA guidance.
A UDI typically includes two key elements:
- device identifier representing the model of the device
- production identifier representing batch or serial information
These identifiers help regulators and healthcare providers track devices during recalls, adverse event investigations, and post-market monitoring.
Required Information Under EU MDR Annex I
Annex I, Chapter III of the EU Medical Device Regulation (EU MDR 2017/745) specifies the information that manufacturers must supply with medical devices to ensure they can be identified, used safely and traced throughout their lifecycle.
Although the exact requirements vary depending on the device type and intended purpose, manufacturers should typically ensure that labels and accompanying Instructions for Use include:
- Manufacturer name and registered address.
- EU Authorised Representative details, where applicable.
- Device name and model.
- Catalogue or reference number.
- Batch number or serial number.
- Unique Device Identifier (UDI).
- Manufacturing and expiry dates where applicable.
- Sterility information.
- Storage and handling conditions.
- Warnings, precautions and contraindications.
- Intended purpose.
- Information necessary for safe installation, operation and maintenance.
Manufacturers should ensure that this information remains consistent across the device label, Instructions for Use, Technical Documentation and Declaration of Conformity. Any design or regulatory changes should trigger a review of all associated labelling documentation through the manufacturer’s change control process.
Instructions for use and safety information
Instructions for Use, often abbreviated as IFU, are a critical component of medical device labelling.
The IFU provides detailed information to ensure safe and effective device use.
Typical IFU content may include:
- device description and intended use
- step-by-step operating instructions
- contraindications and warnings
- maintenance and cleaning instructions
- troubleshooting information
Clear instructions help reduce the risk of user error and ensure that healthcare professionals understand how to use the device correctly.
Medical Device Symbols
Medical device labels frequently use internationally recognised symbols to communicate essential information without relying solely on written text.
The use of harmonised symbols helps reduce language barriers while improving consistency across international markets.
ISO 15223-1 specifies many of the symbols commonly used on medical device labels, including symbols relating to sterility, single-use devices, expiry dates, manufacturer information and storage conditions.
Manufacturers should avoid creating custom symbols unless permitted by applicable standards, as unrecognised symbols may lead to user confusion or regulatory findings.
For a detailed explanation of the latest symbol requirements, read our guide to ISO 15223-1:2025 Medical Device Symbols
Integration with risk management
Labelling requirements are closely linked with device risk management.
The medical device risk management standard ISO 14971 requires manufacturers to identify hazards and implement risk control measures. When risks cannot be fully eliminated through design, labelling may be used to communicate safety information to users.
The ISO risk management framework can be explored through the official overview of ISO 14971:2019.
This integration ensures that warnings and precautions included in device labelling directly reflect the device’s risk profile.
Labelling Review as Part of Change Control
Medical device labelling should not remain static throughout the product lifecycle.
Whenever significant changes are made to the device, manufacturers should assess whether updates to labels, Instructions for Use or regulatory symbols are required.
Examples include:
- Changes to intended purpose.
- Design modifications.
- New manufacturing sites.
- Supplier changes.
- Software updates.
- New warnings arising from post-market surveillance.
- Regulatory updates affecting labelling requirements.
A documented change control procedure helps ensure that all labelling remains accurate, consistent and compliant throughout the commercial life of the device.
Common medical device labelling challenges
Medical device labelling can be complex, particularly for manufacturers operating across multiple regulatory markets.
Common challenges include:
- inconsistent labelling across jurisdictions
- outdated instructions for use
- incomplete UDI implementation
- insufficient safety warnings
- misalignment between labelling and technical documentation
These issues are frequently identified during regulatory audits and conformity assessments.
Practical steps for labelling compliance
Manufacturers seeking to ensure labelling compliance should follow a structured approach.
Recommended steps include:
- Review applicable regulatory frameworks for each target market.
- Define labelling requirements during device design.
- Ensure consistency between labelling and technical documentation.
- Implement UDI requirements where applicable.
- Validate instructions for use through usability testing.
- Maintain documentation supporting regulatory submissions.
- Update labelling when design changes or new safety information emerges.
These steps help ensure that labelling supports regulatory compliance and patient safety.
