MFDS Medical Device Certification Process

# MFDS Medical Device Certification Process

The Ministry of Food and Drug Safety (MFDS / 식품의약품안전처) is the regulatory authority responsible for medical device approval in South Korea. The MFDS certification process is rigorous, well-structured, and respected internationally — but it is also distinctly different from the regulatory pathways Canadian companies are familiar with at Health Canada or the US FDA. Understanding these differences is essential for planning realistic timelines, budgets, and market entry strategies.

This report provides a comprehensive guide to the MFDS medical device certification process, covering device classification, application requirements, Korea Good Manufacturing Practice (KGMP), the Korea License Holder (KLH) requirement, timelines, costs, and practical strategies for efficient approval.

Part 1: Device Classification System

The Four-Class Risk Framework

Korea classifies medical devices into four risk-based categories, aligned with international standards established by the International Medical Device Regulators Forum (IMDRF):

Class I — Low Risk

Examples: Bandages, tongue depressors, manual stethoscopes, basic surgical instruments, examination gloves.

Class I devices are subject to the lightest regulatory requirements. Most Class I devices are exempt from technical review and KGMP certification. Under the Notification Listing System, Class I device manufacturers can complete product registration by uploading registration information onto the MFDS electronic portal. No pre-market review of technical documentation is required.

Exception: Class I sterile devices and Class I measuring devices are regulated like Class II devices and require technical review and KGMP certification.

Class II — Moderate Risk

Examples: Powered surgical instruments, ultrasound imaging systems, infusion pumps, electrocardiographs, dental filling materials.

Class II devices require technical review (기술문서 심사) and KGMP certification. Technical review is conducted by the National Institute of Medical Device Safety Information (NIDS / 의료기기안전정보원), an agency under MFDS.

Class III — Substantial Risk

Examples: Artificial joints, cochlear implants, hemodialysis systems, absorbable sutures, drug-eluting stents.

Class III devices require both technical review and approval by MFDS itself (rather than NIDS). Clinical data requirements are significantly more extensive for Class III devices, and Korean clinical trial data may be required if the device has a novel mechanism of action or significantly different intended use from predicate devices.

Class IV — Highest Risk

Examples: Heart valves, implantable defibrillators, total artificial hearts, deep brain stimulators, Class III IVD devices for critical diagnoses.

Class IV devices undergo the most rigorous review process, comparable to the US FDA's Premarket Approval (PMA) pathway. Full clinical investigation data, including Korean clinical trial data in most cases, is required.
