EU Implementing Regulation 2026/977: Uniform Notified Body Requirements Under MDR and IVDR

Why This Regulation Matters

On May 4, 2026, the European Commission adopted Commission Implementing Regulation (EU) 2026/977 (published in the Official Journal on May 5, 2026) — one of the most consequential pieces of secondary legislation since the MDR and IVDR themselves. It directly addresses three problems that have caused manufacturers years of frustration: unpredictable Notified Body timelines, opaque pricing, and inconsistent re-certification practices across different Notified Bodies.

The regulation was introduced because Notified Bodies across the EU were applying Annex VII of the MDR and IVDR inconsistently. Some Notified Bodies took 180 days for a conformity assessment; others took 400. Some provided detailed quotations upfront; others did not. Some re-certified certificates efficiently; others created bottlenecks. The Commission exercised its power under MDR Article 36(3) and IVDR Article 32(3) to set uniform standards that every Notified Body in the EU must follow.

This guide covers every aspect of Implementing Regulation (EU) 2026/977: what it requires, how it changes the conformity assessment process, when it takes effect, and what manufacturers should do to prepare.

Background: Why the Commission Acted

The Problem of Inconsistent Practices

Since the MDR and IVDR came into force, the European Commission, MedTech Europe, and national Competent Authorities have documented significant inconsistencies in how Notified Bodies interpret and apply the conformity assessment procedures in Annex VII. Key problems included:

• Unpredictable timelines. Manufacturers could not reliably plan product launches because conformity assessment durations varied dramatically between Notified Bodies and even between similar products at the same Notified Body.
• Opaque quotations. Some Notified Bodies provided detailed cost breakdowns; others gave only lump-sum figures with no explanation of how fees were calculated.
• Divergent re-certification practices. When certificates came up for renewal, some Notified Bodies processed re-certification efficiently while others treated it as a de novo assessment, creating avoidable delays and costs.
• Inconsistent clock-stop rules. The rules for when the assessment "clock" could be paused (e.g., when waiting for manufacturer responses) were applied differently across Notified Bodies.

In a February 2026 statement, MedTech Europe emphasized that "predictable certification timelines and fees directly support timely patient access and continuity of supply. These are a bedrock for responsible investment decisions, particularly for small and medium-sized enterprises that rely on regulatory reliability to plan development and allocate resources."

The Legislative Response

The Commission published a draft Implementing Regulation on December 12, 2025, and opened a public consultation that closed in January 2026. Following the consultation, the final regulation was adopted on May 4, 2026, and published on May 5, 2026.

Key Provisions: What the Regulation Requires

Article 1 — Standardized Quotations

Notified Bodies must collect minimum information from manufacturers before issuing a quotation (Article 1(1)(a)-(j)). This includes device identification, classification, conformity assessment route, number of manufacturing sites, and other details that allow the NB to verify the device falls within its designation scope.

The quotation itself must include:

• Scope of assessment activities — a clear description of what will be assessed (QMS audit, technical documentation review, or both)
• Breakdown of fees — itemized costs for each assessment activity, including audit days, documentation review, travel expenses, and any other applicable charges
• Estimated timeline — the expected duration from application to certificate issuance, based on the maximum timelines in Article 2
• Conditions and assumptions — any factors that could affect the quotation (e.g., number of manufacturing sites, complexity of the device)

Fee increase protection (Article 1(4)): If the Notified Body needs to increase fees by more than 10% compared to the original quotation, the manufacturer must be informed in advance. This prevents unexpected cost escalation during an ongoing assessment.

The quotation must be provided within 30 days of receiving a complete application. This gives manufacturers the information needed to compare Notified Bodies and make informed decisions before committing.

Article 2 — Maximum Timelines for Conformity Assessment

This is the most impactful provision for manufacturers. The regulation establishes legally binding maximum timelines for each stage of the conformity assessment process:

Critical detail: The regulation confirms that where the conformity assessment procedure permits parallel running of QMS audit and product verification (as under Annex IX of MDR/IVDR), this parallel approach is explicitly allowed, provided the audit program reflects relevant input from the technical documentation assessment.

Article 3 — Interruption of Timelines (Clock-Stop Rules)

The regulation formalizes when the assessment clock can be stopped:

• Manufacturer-initiated interruptions. When the Notified Body requests additional information or documentation from the manufacturer, the clock stops until the manufacturer provides a complete response.
• Limits on interruptions. Each assessment stage has a maximum number of interruptions (see table above). Once the maximum is reached, the clock continues running regardless.
• No automatic refusal. The regulation explicitly states that expiry of the maximum timelines or use of the maximum number of interruptions is not grounds for the Notified Body to refuse to issue a certificate or approve a change.

This last point is significant. Previously, some manufacturers feared that exceeding timelines would lead to application rejection. The regulation makes clear that timeline expiry is a procedural matter, not a substantive one.

Article 4 — Monitoring and Annual Reporting

Notified Bodies must publish an annual report on their conformity assessment activities, including:

• Effective duration of conformity assessments (actual time, excluding clock-stops)
• Number of applications received, accepted, rejected, and pending
• Cost structures and fee ranges by device type and assessment procedure
• Comparison data across assessment categories

By April 30 each year, every Notified Body must draw up the annual report covering the previous year's activities, publish it on its website, and inform its designating authority and the Commission. The annual reporting requirement (Article 4(4)) takes effect on January 1, 2028.

For manufacturers, this means publicly comparable performance data on every Notified Body in the EU from 2028 onwards. For the first time, the choice between Notified Bodies will be informed by objective data rather than reputation alone. That comparability is likely to drive its own behavioral shift, ahead of any direct enforcement of the timelines.

Some Notified Body industry groups (TÜV Association, IG-NB) expressed concerns that public reporting of costs and timelines could create price pressure and compromise the professional integrity provisions of MDR Article 53(5) and IVDR Article 49(5), which require NBs to be free from financial pressures that might influence their assessment results. The Commission maintained the reporting requirement but framed it as a transparency measure.

Article 5 — Re-Certification of Product Certificates

The regulation introduces streamlined re-certification procedures:

1. Manufacturers must lodge a re-certification application and provide specified documentation before the current certificate expires.
2. The Notified Body must assess the application within 90 days of receipt.
3. The final re-certification decision must be made and the certificate re-issued within 20 days of the final review.

These provisions will not apply to re-certification reviews of certificates expiring before November 25, 2027.

Article 6 — Re-Certification of QMS Certificates

Similar streamlined procedures apply to QMS certificate re-certification, with the same 90-day assessment and 20-day re-issuance requirements.

Article 7 — Structured Dialogue

The regulation formally introduces a legal basis for structured dialogue between manufacturers and Notified Bodies. This allows pre-submission and post-submission discussions based on documented procedures, giving manufacturers an opportunity to clarify requirements, discuss classification questions, and understand assessment expectations before committing to a full application.

This was previously practiced informally by some Notified Bodies but is now a standardized requirement across all of them.

Article 8 — Transparency on Duration and Costs

Notified Bodies must provide manufacturers with:

• Effective duration data — the actual time taken for conformity assessments, excluding periods where the clock was stopped for manufacturer responses
• Cost breakdowns — itemized fees that allow manufacturers to compare pricing between Notified Bodies
• Fee structure explanations — how fees are calculated and what factors influence the final cost

When the Regulation Takes Effect

Articles 1–3 apply to conformity assessment procedures for which the Notified Body and manufacturer signed a written agreement on or after February 25, 2027. The monitoring provisions in Article 4(1)–(3) apply to contracts signed on or after May 25, 2027. Agreements signed before the relevant application date continue under the previous rules.

What This Means for Manufacturers

Immediate Benefits

1. Predictable timelines. You can now plan product launches with much greater certainty. The maximum 120-day QMS audit, 90-day product verification, and 30-day application review give you a clear framework for scheduling.

2. Transparent pricing. Standardized quotations with itemized fee breakdowns allow you to compare Notified Bodies on cost as well as capability, and budget more accurately for conformity assessment expenses.

3. Consistent re-certification. The 90-day re-certification window with a 20-day certificate re-issuance requirement eliminates the unpredictability that previously surrounded certificate renewal.

4. Formal structured dialogue. Pre-submission discussions are now a standardized right, not an informal courtesy. Use them to clarify classification questions, discuss technical documentation expectations, and align on assessment scope before committing.

5. Parallel processing confirmed. Where Annex IX allows it, QMS audits and product verification can run in parallel, potentially saving months of total assessment time.

Strategic Considerations

• Agreements signed before February 25, 2027 are not covered by the new timeline rules. If you are currently in the conformity assessment process, the old rules continue to apply to your existing agreement.
• The maximum timelines are ceilings, not targets. Well-prepared manufacturers with complete documentation should expect assessments to complete faster than the maximum. The timelines exist to prevent excessive delays, not to set the standard duration.
• The clock-stop rules work both ways. Manufacturers must respond promptly to Notified Body requests. Excessive delays in providing information will consume your available interruptions and could slow the process.

How to Prepare

For Manufacturers Currently Selecting a Notified Body

1. Request standardized quotations from multiple Notified Bodies. Compare not just price but also estimated effective duration, scope of assessment, and structured dialogue offerings.
2. Ask about parallel processing. If your device qualifies for Annex IX assessment, confirm that the Notified Body is prepared to run QMS and product verification in parallel.
3. Understand the clock-stop rules. Before signing an agreement, clarify how the Notified Body handles information requests and what constitutes a "complete response" from the manufacturer.

For Manufacturers Already in the Assessment Process

1. Check whether your agreement falls under the new rules. Agreements signed before February 25, 2027 continue under the old framework.
2. If your agreement is still being negotiated, consider timing the signature to fall on or after February 25, 2027 to benefit from the new timeline protections.
3. Prepare for re-certification under the new rules. If your certificate will be up for renewal after November 25, 2027, the streamlined re-certification process will apply.

For All Manufacturers

1. Use the structured dialogue mechanism. Before submitting your next application, request a structured dialogue to discuss classification, documentation expectations, and assessment scope.
2. Plan your responses to NB requests. Complete, well-organized responses to information requests minimize clock-stops and keep the assessment on track.
3. Monitor the annual reports. Starting in 2028, Notified Body annual reports will provide valuable data for comparing NBs on actual performance (not just promises).

Relationship to the Broader MDR/IVDR Reform

Implementing Regulation (EU) 2026/977 is part of a larger package of reforms. On the same day (May 5, 2026), MedTech Europe published its position paper on the MDR and IVDR revision, calling for a "simpler, more predictable framework for patient access and innovation." The implementing regulation addresses one critical piece of this puzzle — Notified Body consistency — while the broader legislative revision addresses structural issues like classification, clinical evidence requirements, and innovation pathways.

The Implementing Act on Annex VII should be viewed as complementary to the forthcoming targeted revisions of MDR and IVDR. Together, these measures aim to improve the predictability, transparency, and efficiency of the European regulatory framework for medical devices.

Key Takeaways

1. Implementing Regulation (EU) 2026/977 sets uniform quality management and procedural requirements for all Notified Bodies under the MDR and IVDR.
2. Maximum timelines are now legally binding: 30 days for application review, 120 days for QMS audit, 90 days for product verification, and 20 days for certificate re-issuance.
3. Standardized quotations with itemized fee breakdowns are mandatory, enabling meaningful comparison between Notified Bodies.
4. Streamlined re-certification must be completed within 90 days of receiving a complete application, with certificates re-issued within 20 days.
5. Structured dialogue between manufacturers and Notified Bodies is now a formalized right, not an informal courtesy.
6. Articles 1–3 take effect February 25, 2027 (monitoring provisions from May 25, 2027), applying to agreements signed on or after the respective dates.
7. Annual transparency reporting by Notified Bodies begins January 1, 2028.
8. Parallel QMS/product assessment is explicitly confirmed, potentially saving months in the overall conformity assessment timeline.
