How Long Does MFDS Approval Take? Medical Device Timeline in South Korea

One of the most common questions from medical device manufacturers is:

👉 “How long does it take to get MFDS approval in South Korea?”

The answer depends on several factors, including: --> Device classification (Class I–IV) --> KGMP certification status --> Clinical data requirements --> Documentation quality

In this guide, we provide a detailed, real-world breakdown of MFDS approval timelines, including hidden delays and strategies to accelerate market entry.

MFDS Approval Timeline – Quick Overview

👉 These are ideal timelines — real timelines may vary based on multiple factors.

Key Factors Affecting MFDS Timeline

1. Device Classification (Primary Driver)

Higher classification = more requirements: --> Class I → Minimal review --> Class II → Moderate review --> Class III/IV → Full technical + clinical review

2. KGMP Certification Status

KGMP is often the biggest bottleneck.

Scenarios: --> Already KGMP certified → Faster approval --> Not certified → Adds 6–16 weeks

3. Clinical Data Requirements --> Not required → Faster approval --> Required → Adds months

4. Technical Documentation Quality --> Well-prepared file → smooth review --> Poor documentation → multiple queries

5. Korea License Holder (KLH) Efficiency --> Experienced KLH → faster communication --> Weak KLH → delays in responses

Detailed Timeline Breakdown (Step-by-Step)

Phase 1: Preparation Stage

👉 Total: 4–8 weeks

Phase 2: KGMP Certification (If Required)

👉 Total: 6–16 weeks

Phase 3: MFDS Review Process

👉 Total: 6–12 weeks

Timeline with Clinical Trials (Advanced Scenario)

For high-risk or innovative devices:

👉 Adds 6–18 months to timeline

Real-World Timeline Scenarios

Scenario 1: Class II Device (No Clinical Data) Documentation ready KGMP completed

👉 Timeline: 3–5 months

Scenario 2: Class III Device (With Clinical Data) Clinical evidence required Moderate audit findings

👉 Timeline: 8–12 months

Scenario 3: Class IV Implantable Device Full clinical trials Strict review

👉 Timeline: 12–24 months

Hidden Delays (Most Companies Ignore)

1. MFDS Deficiency Letters Missing documents Clarifications required

👉 Each round adds 2–6 weeks

2. Translation Issues Incorrect Korean translation Inconsistent terminology

👉 Leads to re-submission

3. Poor CAPA Management Weak corrective actions Delayed responses

4. Incorrect Classification

👉 Can restart the entire process

How to Reduce MFDS Approval Time

1. Start KGMP Early - Parallel processing saves months

2. Prepare High-Quality Technical File - Avoids multiple review cycles

3. Use Experienced KLH - Ensures faster communication

4. Conduct Pre-Submission Review - Identify gaps early

5. Align Documentation Globally - Reuse FDA/EU data strategically
