EU MDR Article 22: Systems and Procedure Packs — Producer Obligations Guide
Complete guide to EU MDR Article 22 system and procedure pack producer obligations, the no-additional-CE-mark rule, Article 22(4) triggers, UDI, and the FDA convenience-kit comparison.
Does a System or Procedure Pack Get Its Own CE Marking?
No. Under EU MDR Article 22(5), a system or procedure pack assembled from individually CE-marked devices does not itself bear an additional CE marking. The entity that assembles the pack becomes a "system or procedure pack producer" — a role with specific but lighter obligations than a full manufacturer under Article 10. The producer verifies device compatibility, draws up a statement, applies internal quality methods, assigns the pack its own UDI and Basic UDI-DI, and runs post-market surveillance. This lighter-obligation "producer" role is unique to the EU MDR and has no direct equivalent under US FDA rules, where a convenience kit is simply another device subject to the same mainstream regulatory requirements.
However, three specific triggers under Article 22(4) can collapse the producer role into full manufacturer status: incorporating a non-CE-marked device, combining devices in an incompatible way, or sterilizing the pack in a manner that departs from the manufacturer's instructions. Understanding exactly where the line falls between a "producer" and a "manufacturer" is the central challenge of Article 22 compliance.
This guide covers the full scope of Article 22 obligations based on the consolidated text of Regulation (EU) 2017/745 (CELEX 02017R0745-20250110), the MDCG 2018-3 Rev.1 UDI guidance, and provides a side-by-side comparison with US FDA convenience-kit rules under 21 CFR 801.3.
What Is a System vs. a Procedure Pack Under the MDR?
Article 22(1) of the MDR defines two categories:
System: A combination of devices, and possibly other products, which are "intended to be interconnected or combined in order to achieve a specific medical purpose." A configured surgical system — for example, a powered instrument console combined with handpieces, cables, and footswitch — is a typical system.
Procedure pack: A combination of devices "packaged together and placed on the market for the purpose of being used for a specific medical procedure." The classic example is a custom surgical tray (also called a custom procedure pack or CPP) containing drapes, gowns, swabs, instruments, and other devices pre-assembled for a specific surgery.
Both categories share the same Article 22 regulatory framework. The critical condition is that each device in the system or procedure pack must already bear a valid CE marking for the relevant intended purpose under the MDR. If this condition is not met, Article 22(4) applies and the entire assembly becomes a "device in its own right."
Commercial Context
The custom procedure pack industry is substantial. Cardinal Health's Presource brand, which the company says "pioneered the procedural pack business more than 40 years ago," serves more than 4,000 hospitals and ambulatory surgery centers. Owens & Minor's SurgiTrack and Mölnlycke's ProcedurePak are other major examples. These companies operate as system/procedure pack producers under Article 22 — unless their assembly activities trigger Article 22(4).
What Obligations Does the System/Procedure Pack Producer Have Under Article 22?
Article 22 spreads the producer's obligations across paragraphs (1), (2), and (3). The central requirement is that the producer draws up a statement — a specific Article 22 document that is distinct from a manufacturer's EU Declaration of Conformity. The CE-marking precondition sits in paragraph (1), and the exact content the statement must declare is fixed by the three sub-points of paragraph (2).
Article 22(1) — The CE-Marking Precondition and the Statement
The producer may only combine devices that already bear a valid CE marking under the MDR — together, optionally, with CE-marked IVDs placed on the market under Regulation (EU) 2017/746, and with other non-device products that conform with the legislation applicable to them when used in a medical procedure. The combination must be compatible with the intended purpose of the devices and stay within the limits of use specified by their manufacturers. In practice this means verifying, for each component, that the CE marking is valid (not an expired MDD/AIMDD marking that has lost its transitional validity) and that the manufacturer's EU Declaration of Conformity is in place.
This is not a one-time check. The producer must have a process to detect when a component device's CE marking expires, when a manufacturer withdraws a Declaration of Conformity, or when a notified body certificate is suspended or restricted.
Article 22(2) — What the Statement Must Declare
In the statement, the producer must declare three things, in the exact terms the regulation sets out:
Article 22(2)(a) — Mutual compatibility verified. The producer verified the mutual compatibility of the devices (and other products, if any) in accordance with the manufacturers' instructions and carried out its activities in accordance with those instructions. In practice this covers physical and functional compatibility (electrical interfaces, mechanical connections, fluid pathways), mutual non-interference (electromagnetic compatibility, material interactions), and consistency with the manufacturers' IFUs, warnings, and contraindications. The compatibility verification must be documented and maintained as part of the producer's internal quality system.
Article 22(2)(b) — Packaging and user information supplied. The producer packaged the system or procedure pack and supplied relevant information to users, incorporating the information to be supplied by the manufacturers of the devices or other products that were put together. In other words, the producer is responsible for assembling the pack's labeling and documentation so that the user receives the relevant manufacturer instructions for each component.
Article 22(2)(c) — Appropriate methods of internal monitoring, verification and validation. The combining activity was subject to "appropriate methods of internal monitoring, verification and validation." This is deliberately lighter than the full manufacturer quality management system under Article 10(9) — the producer does not need the complete scope of an Article 10 manufacturer QMS. However, the internal quality system must be adequate to control incoming device inspection and CE-marking verification, compatibility assessment, packaging and labeling, traceability and documentation, and post-market surveillance data collection and analysis.
In practice, most system/procedure pack producers maintain an ISO 13485 quality management system — not because Article 22 strictly requires it, but because notified bodies, customers, and competent authorities expect a recognized quality standard, and ISO 13485 provides the framework for the "appropriate methods" that Article 22(2)(c) demands.
The Article 22 statement is distinct from — and does not replace — the individual manufacturer's EU Declaration of Conformity for each component device under Annex IV.
When Does Article 22(4) Turn a Pack Into a "Device in Its Own Right"?
Article 22(4) defines three triggers, each individually sufficient to reclassify the system or procedure pack as a "device in its own right" and impose full manufacturer obligations on the assembler:
Trigger 1: Non-CE-Marked Device
If the system or procedure pack includes a device that does not bear a valid CE marking — for example, a device whose notified body certificate has expired, a device still under MDD transitional provisions that have lapsed, or a non-medical accessory that should have been CE-marked — the entire assembly is treated as a device in its own right.
Trigger 2: Incompatible Combination
If the chosen combination of devices is not compatible within the system or procedure pack's intended purpose — for example, if electrical interfaces are mismatched, if the combination creates a hazard not addressed in any individual device's risk management, or if the intended use of one device contradicts the intended purpose of another — the assembly becomes a device in its own right.
Trigger 3: Non-Manufacturer Sterilization
If the sterilization of the system or procedure pack has not been carried out in accordance with the relevant manufacturer's instructions — for example, if the producer re-sterilizes a device using a method or cycle not validated by the device manufacturer, or sterilizes a device the manufacturer labeled as non-sterile — the assembly becomes a device in its own right.
Consequences of Article 22(4)
When any of the three triggers fires, the entity that assembled the system or procedure pack assumes the obligations incumbent on manufacturers under the relevant conformity assessment procedure. This means:
- Full Article 10 manufacturer obligations, including a comprehensive QMS
- Conformity assessment through a notified body (for Class IIa, IIb, and III devices)
- Technical documentation per Annexes II and III
- EU Declaration of Conformity per Annex IV
- CE marking per Article 20
- Registration in EUDAMED as a manufacturer
- Full post-market surveillance per Articles 83–86
The transition from "producer" to "manufacturer" is binary and automatic — there is no intermediate status.
What Happens If the Producer Sterilizes the Pack? Article 22(3)
Many procedure packs are supplied sterile. Article 22(3) addresses this scenario directly:
If the system or procedure pack producer sterilizes the pack (or has it sterilized), the producer must apply Annex IX or Annex XI Part A — but the notified body's involvement is "limited to the aspects of the procedure relating to ensuring sterility" until the system or procedure pack is opened or its packaging is damaged.
This means:
- The notified body audits and certifies the sterilization process (validation, environmental monitoring, bioburden testing, sterility assurance level)
- The notified body does not assess the individual devices within the pack (the device manufacturers' notified bodies have already done that)
- The producer does not need to submit the full technical documentation for each component device to the sterilization notified body
Critical Boundary
If the sterilization departs from the relevant manufacturer's instructions — for example, if a device manufacturer specifies EtO sterilization and the pack producer uses gamma irradiation — this triggers Article 22(4), and the pack becomes a device in its own right. The producer then assumes full manufacturer obligations for the entire assembly.
How Is UDI Handled for Systems and Procedure Packs?
The Unique Device Identification (UDI) system applies to systems and procedure packs at two levels:
Pack-Level UDI
Annex VI Part C, section 3.7 of the MDR states that systems and procedure packs "shall be assigned and bear their own UDI." This pack-level UDI is placed on the outer packaging of the system or procedure pack and identifies the pack as a whole.
Basic UDI-DI at the Pack Level
Article 29(2) requires that a Basic UDI-DI be assigned at the system or procedure pack level. The Basic UDI-DI is the primary identifier of a device model in EUDAMED and is used for linking regulatory information (certificates, vigilance reports, clinical investigations) to the system or procedure pack.
Component-Level UDI
Each component device within the system or procedure pack retains its own UDI, assigned by the device manufacturer. The pack-level UDI does not replace the component UDIs — it adds an additional identification layer for the assembled combination.
MDCG 2018-3 Rev.1 Guidance
The European Commission's MDCG 2018-3 Rev.1 provides detailed guidance on UDI assignment for systems and procedure packs, including:
- When to assign a new UDI-DI to the pack versus when to use the existing component UDI-DIs
- How to handle variable-composition packs (where the exact device mix may change per customer order)
- EUDAMED registration obligations for the system/procedure pack producer
Article 16 vs. Article 22: When Is the Assembler a Manufacturer Instead of a Producer?
The boundary between Article 22 (system/procedure pack producer) and Article 16 (manufacturer-equivalent) is one of the most practically important distinctions in the MDR.
Article 16(1) — Manufacturer-Equivalent Triggers
Under Article 16(1), any natural or legal person who carries out any of the following activities is considered a manufacturer and must assume full Article 10 obligations:
- Changes the intended purpose of a device already placed on the market or put into service
- Modifies a device already placed on the market in a way that affects compliance with applicable requirements
- Supplies a device under their own name, registered trade name, or registered trademark (except as a distributor or importer who adds their name to the label without changing the device or its intended purpose)
Article 22 — Producer Activities
The Article 22 producer assembles CE-marked devices without modification into a system or procedure pack. The producer does not:
- Change the intended purpose of any individual device
- Modify any device (other than opening and repacking, as appropriate for the pack)
- Market individual devices under the producer's own brand (the pack is identified as a system/procedure pack, not as a new device)
The Health-Institution Exception: Article 5(5)
Hospitals and other health institutions that assemble systems or procedure packs for internal clinical use may fall under the Article 5(5) health-institution exemption, provided they meet all of the following conditions:
- The system or procedure pack is not transferred to another legal entity
- The assembly is carried out under an appropriate quality management system
- The health institution draws up a declaration listing the devices and confirming compatibility
- The combination is not a device already commercially available
This exemption is narrow and heavily conditioned. Health institutions that assemble packs for sale or transfer to other entities are not covered by Article 5(5) and must comply with Article 22 (or Article 10/16 if Article 22(4) triggers apply).
How Does Article 22 Differ From FDA Convenience-Kit (21 CFR 801.3) Rules?
The EU MDR "system/procedure pack producer" concept has no direct US equivalent. Under FDA rules, a convenience kit is simply another device subject to mainstream regulatory requirements. The following table compares the two frameworks:
| Dimension | EU MDR Article 22 (System/Procedure Pack) | US FDA Convenience Kit (21 CFR 801.3) |
|---|---|---|
| Definition | Devices combined for a specific medical purpose (system) or specific procedure (pack) | "Two or more different medical devices packaged together for the convenience of the user" |
| CE/Clearance on the pack | No additional CE marking — Article 22(5) | The kit is a device; no separate 510(k) required if every component is legally marketed and the kit does not create new intended uses |
| Regulatory status of assembler | "Producer" with lighter obligations — unless Article 22(4) triggers ⟶ full manufacturer | Establishment registration and device listing under 21 CFR Part 807; specification developer or manufacturer |
| QMS obligation | "Appropriate methods of internal monitoring, verification and validation" — Article 22(2)(c) | Full 21 CFR Part 820 current good manufacturing practice (cGMP / QMSR) |
| UDI | Pack-level UDI + Basic UDI-DI; components keep their own UDI | Kit UDI on outer label; components excepted from individual UDI labeling per 21 CFR 801.30(a)(11) |
| Sterilization | Annex IX or XI Part A; NB involvement limited to sterility aspects | Full 21 CFR Part 820 sterilization process validation; no separate notified-body concept |
| Drug inclusion | Device pack with a medicinal product substance triggers additional requirements under Article 1(8)/(9) | Drug-device combination product ⟶ 21 CFR Part 4 |
| Key regulatory concept | Distinct "producer" role (Article 22) vs. "manufacturer" role (Article 10) | No separate "producer" concept; kit packer is a manufacturer or specification developer |
| Postmarket obligations | PMS (Articles 83–86) for the system/procedure pack | MDR / complaint handling under 21 CFR Part 803 and Part 820 |
Key Takeaway
The EU MDR creates a lighter regulatory pathway for assemblers of CE-marked devices through the "producer" concept, provided all Article 22 conditions are met. The FDA offers no equivalent lighter pathway — a convenience-kit packer is subject to the same registration, listing, QMS, and reporting requirements as any other device manufacturer or specification developer. For companies operating in both markets, this means that complying with the more demanding FDA requirements will generally satisfy the EU producer obligations, but not vice versa.

Practical Decision Tree for the Assembler
The following decision flow summarizes the Article 22 analysis:
Step 1. Are ALL component devices CE-marked under the MDR with valid certificates?
- No → Article 22(4) → You are a full manufacturer under Article 10. Go through the applicable conformity assessment procedure.
- Yes → Continue.
Step 2. Is the chosen combination compatible within the system or procedure pack's intended purpose?
- No → Article 22(4) → You are a full manufacturer.
- Yes → Continue.
Step 3. If the pack is sterilized, is sterilization carried out in accordance with each relevant manufacturer's instructions?
- No → Article 22(4) → You are a full manufacturer.
- Yes → Continue.
Step 4. You are a system/procedure pack producer under Article 22. Your obligations are:
- Combine only CE-marked devices (and eligible IVDs/other products) and draw up the Article 22 statement — Article 22(1)
- In the statement, declare mutual-compatibility verification, packaging/information supplied, and appropriate methods — Article 22(2)(a)-(c)
- Assign pack-level UDI and Basic UDI-DI — Annex VI Part C, Article 29(2)
- Conduct post-market surveillance for the system/procedure pack
Step 5. Is the producer sterilizing the pack?
- Yes → Notified-body involvement under Article 22(3), limited to sterilization aspects (Annex IX or Annex XI Part A).
- No → No notified-body involvement specifically for the pack (but each component device still has its own notified-body certificate where applicable).
Frequently Asked Questions
Does a Procedure Pack Producer Need a Full ISO 13485 / Article 10 QMS?
Article 22(2)(c) requires "appropriate methods of internal monitoring, verification and validation" — not the full Article 10(9) manufacturer QMS. In practice, most producers maintain an ISO 13485 system because (a) competent authorities and notified bodies expect a recognized quality standard, (b) customers and tenders require it, and (c) it provides the framework for the "appropriate methods" the regulation demands. However, the scope of the ISO 13485 system can be tailored to the producer's activities (assembly, packaging, labeling, sterilization oversight, PMS) rather than covering the full design and manufacturing scope of a device manufacturer.
If the Producer Sterilizes the Pack, Does That Change the Obligations?
Yes. Article 22(3) requires notified-body involvement for sterilization, but the involvement is "limited to the aspects of the procedure relating to ensuring sterility." The producer must apply Annex IX or Annex XI Part A for the sterilization process. Critically, if the sterilization method departs from the device manufacturer's validated instructions, Article 22(4) is triggered and the producer becomes a full manufacturer for the entire assembly.
Can a Hospital Assemble Procedure Packs Without Becoming a Manufacturer?
Potentially, under the Article 5(5) health-institution exemption. The hospital must meet all conditions: the pack is used only within the same legal entity (not transferred or sold), an appropriate quality management system is in place, the compatibility of devices is verified and documented, and the combination is not otherwise commercially available. If any condition is not met — particularly if the hospital sells or transfers the packs to another entity — the hospital must comply with Article 22 as a producer, or with Article 10 if Article 22(4) triggers apply.
Does the Procedure Pack Need a Declaration of Conformity?
Not a manufacturer's Declaration of Conformity. Under Article 22(1), the producer draws up an Article 22 statement whose content is defined by Article 22(2): it declares that mutual compatibility was verified per the manufacturers' instructions (22(2)(a)), that the pack was packaged and user information supplied (22(2)(b)), and that appropriate methods of internal monitoring, verification and validation were applied (22(2)(c)). This statement is not the manufacturer's EU Declaration of Conformity under Annex IV — it is a lighter, producer-specific document, and each component device still retains its own manufacturer-issued Declaration of Conformity.
What About Procedure Packs That Include a Medicinal Product?
If a system or procedure pack includes a medicinal product (not a device), additional requirements arise. The MDR Article 1(8) and (9) address device-drug combinations, and the classification rules in Annex VIII (particularly Rule 14) may apply. The medicinal product must be authorized under the relevant pharmaceutical legislation (Directive 2001/83/EC or Regulation (EC) No 726/2004). In most cases, the inclusion of a non-device product means the assembly goes beyond the scope of Article 22 and requires a more comprehensive regulatory strategy.
What Is the Relationship Between Article 22 and the EUDAMED Registration?
System/procedure pack producers must register as economic operators in EUDAMED and register their systems/procedure packs with the assigned UDI and Basic UDI-DI. The specific EUDAMED modules relevant to producers include the Actor Registration module and the UDI/Device Registration module. MDCG 2018-3 Rev.1 provides guidance on the UDI registration process for systems and procedure packs.
