Korea’s medical device regulatory framework is undergoing a significant transformation. With the introduction of MFDS Notice 2026-6, the Ministry of Food and Drug Safety has implemented one of its most comprehensive regulatory updates in recent years, revising the Regulation on Medical Device Approval, Notification, and Review.

Rather than serving as a routine procedural update, this notice reflects a broader shift toward international alignment, operational consistency, and regulatory transparency. By strengthening its connection to International Medical Device Regulators Forum (IMDRF) standards, MFDS aims to create a more predictable and globally compatible approval environment.

For manufacturers seeking access to the Korean market, understanding these changes is no longer optional. Classification rules, documentation standards, review pathways, and post-market obligations have all been refined. 

Together, these updates reshape how companies prepare, submit, and maintain regulatory approvals in Korea. This article provides a detailed comparison of the previous and updated requirements under MFDS Notice 2026-6 and explains what they mean in practical terms.

Why MFDS Introduced Notice 2026-6

Before this revision, Korea’s regulatory system faced persistent structural challenges. Interpretation often varied between reviewers, documentation expectations were not always consistent, and emerging technologies (particularly software-based and AI-enabled devices) were insufficiently addressed.

These gaps created uncertainty for manufacturers and, in some cases, led to prolonged review timelines and repeated requests for clarification.

MFDS Notice 2026-6 was designed to resolve these issues by:

  • Aligning national regulations with IMDRF frameworks
  • Clarifying ambiguous definitions and classification criteria
  • Standardizing documentation and review procedures
  • Improving transparency across approvals, inspections, and notifications
  • Supporting innovation through more flexible regulatory pathways

Collectively, these changes aim to strengthen regulatory rigor while reducing unnecessary friction for compliant manufacturers.

Clearer Definitions and Device Categorization

Previous Framework

Under the previous system, device categorization was only partially harmonized with international standards. Important distinctions, such as those between combination products, integrated systems, components, and accessories, were often open to interpretation.

Software-based technologies were particularly affected, as they lacked consistent classification rules and were frequently evaluated on a case-by-case basis.

Updated Requirements

Notice 2026-6 introduces standardized, IMDRF-aligned definitions that bring greater clarity and consistency to device classification.

The revised framework:

  • Clearly differentiates between combination, integrated, and single-use devices
  • Establishes explicit criteria for components and accessories
  • Formally defines Software as a Medical Device (SaMD)
  • Standardizes new device classification rules

As a result, manufacturers can now approach classification with greater confidence and fewer regulatory uncertainties.

Strengthened Oversight of Software as a Medical Device (SaMD)

Previous Framework

Historically, SaMD submissions in Korea were governed by fragmented guidance. Artificial intelligence and algorithm-based functions were not explicitly regulated, while expectations for software updates, cybersecurity, and data management remained unclear.

This lack of consistency made regulatory planning particularly challenging for digital health developers.

Updated Requirements

Under Notice 2026-6, software regulation has been substantially strengthened.

The revised framework now provides:

  • A formal, IMDRF-aligned SaMD definition
  • Explicit regulatory treatment of AI-driven functionality
  • Defined requirements for data transmission and storage
  • Standardized software documentation structures
  • Clear differentiation between embedded and standalone software

These changes establish a more predictable regulatory environment for digital technologies while reinforcing patient safety and data integrity.

Mandatory IMDRF STED Technical Documentation

Previous Framework

Previously, technical documentation formats varied widely. Although the IMDRF Summary Technical Documentation (STED) model was encouraged, its use was often optional, and safety and performance data were not always presented consistently.

Updated Requirements

Notice 2026-6 makes the IMDRF STED format mandatory for applicable submissions.

This transition introduces:

  • A uniform structure for technical files
  • Clear expectations for safety and performance evidence
  • Harmonized risk management and usability documentation
  • Enhanced labeling and packaging standards

By standardizing technical submissions, MFDS has reduced reviewer subjectivity and simplified regulatory preparation for multinational manufacturers.

Harmonized Performance and Safety Testing Standards

Previous Framework

Testing requirements previously differed by device type and reviewer interpretation. International standards were not always applied consistently, and software validation expectations were limited.

Updated Requirements

The revised regulation introduces harmonized testing protocols aligned with global benchmarks, including:

  • Defined criteria for mandatory testing
  • Expanded software validation requirements
  • Standardized biocompatibility and electrical safety protocols
  • Clearer clinical evaluation expectations

These updates improve consistency across conformity assessments and reduce approval delays caused by testing discrepancies.

Formalized Pre-Submission Review Procedures

Previous Framework

Pre-review processes were largely informal. Eligibility requirements were unclear, timelines were unpredictable, and feedback quality varied significantly.

Updated Requirements

Notice 2026-6 establishes a structured pre-submission framework that includes:

  • Clearly defined procedural steps
  • Standardized documentation requirements
  • Transparent eligibility criteria
  • Predictable review timelines
  • Consistent, documented feedback

This allows manufacturers to identify regulatory risks earlier and address them proactively.

Streamlined Approval and Certification Pathways

Previous Framework

Approval pathways often depended on individual reviewer interpretation, particularly for novel and hybrid devices. Exemption criteria were narrow, and review timelines lacked consistency.

Updated Requirements

The revised framework simplifies and standardizes market entry pathways by:

  • Clarifying procedures for innovative and hybrid products
  • Expanding exemption categories
  • Defining boundaries between approval and certification
  • Establishing standardized review timelines

These improvements support more reliable regulatory planning and commercialization strategies.

Improved Change Management and Notification Requirements

Previous Framework

Manufacturers frequently faced uncertainty about when design or manufacturing changes required re-notification. Documentation standards varied, and enforcement was inconsistent.

Updated Requirements

Notice 2026-6 introduces structured lifecycle management requirements, including:

  • Clear triggers for re-notification
  • Defined responsibilities for manufacturers and distributors
  • Standardized notification documentation
  • Formal change control reporting systems
  • Enhanced compliance monitoring

This strengthens regulatory traceability throughout the product lifecycle.

Standardized Inspection and Verification Procedures

Previous Framework

Inspection practices differed across regions and inspectors. Reporting formats were inconsistent, and follow-up timelines were not always clearly defined.

Updated Requirements

The revised regulation establishes unified inspection protocols that include:

  • Standardized evaluation criteria
  • Uniform inspection certificate formats
  • Transparent reporting processes
  • Defined corrective action timelines
  • Risk-based inspection frequencies

These measures promote greater consistency and accountability in regulatory oversight.

Clearer Same Product Group Criteria
