South Korea: An interesting market for medical device manufacturers

A German medical technology industry analysis from 2020 estimated the market for medical devices in South Korea at USD 6.7 billion. Due to an annual growth rate of imports of (estimated) 10% and the increasing aging of the population with a simultaneous increase in basic medical care, the South Korean market is expected to grow continuously.

This article highlights the regulatory framework that must be adhered to when selling medical devices in South Korea and the hurdles that must be overcome.

Regulatory framework

a) Responsibility

Since 2017, the MFDS (Ministry of Food and Drug) has been responsible for the regulation and approval of medical devices in South Korea. The MFDS is responsible for the registration of medical devices, the definition of regulations, and the issuance of certificates.

b) Regulations

The legal framework for the registration and distribution of foreign medical devices and in vitro diagnostic devices in South Korea is provided by the Medical Device Act and the Act on In vitro Diagnostic Medical Devices. The legal texts serve the following objective and purpose (taken from the English translation):

• The purpose of this Act [Medical Device Act] is to promote the efficient management of medical devices and further contribute to the improvement of public health by providing for matters concerning the manufacturing, import, distribution, etc. of medical devices. (Medical Device Act).
• The purpose of this Act [Diagnostic Medical Devices] is to improve public health and contribute to the advancement of in vitro diagnostic medical devices through ensuring safety, improving quality, and strengthening international competitiveness, of such devices by providing for matters necessary for handling, such as manufacturing and import, and management of, and support for the devices (Act On In Vitro Diagnostic Medical Devices).

c) Medical device qualification in South Korea

The definition of a medical device can be found in Article 2 of the Medical Device Act. This defines a medical device as follows:

For definitions of in vitro diagnostic devices, see the Act on In Vitro Diagnostic Medical Devices.

The steps to product registration in South Korea

The registration process for foreign medical devices in South Korea is shown in Fig. 1. The objective of this process is the approval or issuance of a pre-market approval license for your devices by the South Korean authorities and the associated possibility of importing and distributing your devices on the South Korean market.

Step 1: Designation of the Korean License Holder KLH

Before starting the registration process of their medical devices, manufacturers without a branch in South Korea must appoint a Korean License Holder (KLH) in the country and conclude a contract with him. The KLH acts as the legal representative to the Ministry (MFDS).

Korean License Holders must meet the following requirements:

• Be a resident of South Korea and have a registered office in South Korea
• Be registered as a KLH at MFDS with a license for medical devices and in vitro diagnostic devices
• Be registered as a quality manager at MFDS

Step 2: Classification of the medical device

The MFDS uses a four-level classification system for medical devices based on the risk to the human body. It follows the approach of the Global Harmonization Task Force (GHFT) Principles of Medical Devices Classification or the analogous IMDRF rules.

As a first aid for the classification of devices, the database Medical Device Products and their Assigned Classes of the MFDS can be used. At regular intervals, the MFDS publishes an updated overview of classifications of registered medical devices in the database, including examples, descriptions, and category numbers.

Step 3: Certification according to Korean Good Manufacturing Practices

Foreign manufacturers of medical devices (including in vitro diagnostics) must have their QM system certified with regard to KGMP (Korean Good Manufacturing Practices) before the start of the respective product registration.

KGMP certification is intended to ensure that medical devices are produced, controlled, and followed up in accordance with the requirements and quality standards of MFDS. Detailed information on the implementation of KGMP is provided in the Regulation on Good Manufacturing Practices (GMP) for Medicinal Products.

Class II to IV devices are affected by KGMP certification. Class I medical devices are exempt from this obligation.

The application for KGMP certification is submitted to the MFDS by the Korean License Holder (KLH) chosen and contracted by the foreign manufacturer of the medical device.

In the case of new registrations, the inspection is carried out as an on-site audit of the production facility. The costs range from USD 4,000 to USD 6,000, depending on the scope. A lead time of several months is to be expected here. 

In the case of product registration with a valid KGMP certificate or when the certificate is renewed, a document audit is carried out. The costs are between USD 1,000 and 1,500. A duration of several weeks is to be expected.

The KGMP certificate remains valid for three years and must then be renewed.

Step 4: Product registration

The "approval procedures" of medical devices in South Korea (also defined as registration or certification of medical devices) differ depending on the defined medical device class (I to IV). The different procedures are described in more detail below.

Registration of class I devices (4a)

Manufacturers of class I medical devices submit an application for product notification to the NIDS (National Institute of Medical Device Safety Information) for the registration of their devices.

After successfully uploading the complete application, including all information, the manufacturer can independently complete the product registration of its class I medical devices. There is a cost associated with this process of approximately USD 75.

Certification for class II devices (4b)

The approval or certification procedures of class II devices differ in terms of Substantial Equivalency (SE). According to the MFDS regulations, the devices are divided into four categories:

1. Recognized SE (Substantial Equivalency) Devices
2. SE (Substantial Equivalency) Devices
3. Modified Device
4. New Devices

Devices of categories 1 to 3 require a product certification by the NIDS. For this purpose, an application for product notification must be submitted to the NIDS (analogous to class I devices). This must be supplemented by additional documents.

For category 1 devices (Recognized SE Devices), a Test Report of Safety and Performance is required in addition to the application for Product Notification. A processing time of five days and a cost of approximately USD 120 for certification can be expected.

Category 2 (SE Devices) and category 3 (Modified Devices) devices undergo a detailed review of the documents to be submitted in addition to the application for Product Notification. For the review of the additional documents, a processing time of 25 days and costs of approx. USD 120 can be expected.

In the case of category 2 devices (SE Devices), an evaluation of comparison data with devices already on the market must be prepared in addition to the information on category 1 devices.

For category 3 devices (modified devices), documentation of the origin and development process, including the usage status overseas, must be prepared in addition to the information on category 2 devices.

Approval of devices in class II (New Devices) and classes III to IV (4c)

For class II medical devices in category 4 (New Devices) and class III and IV devices, an application for approval is submitted to the MFDS.

There are two options for manufacturers:

1. General review of the technical documentation
2. Inspection of the safety and effectiveness of the device (SER file)

For the review of the documents, a processing time of 60 to 80 days and costs of between USD 600 and 1,200 (depending on the medical device class) can be expected.

In addition to the approval application and the technical documentation or SER, further relevant information must be provided or submitted:

• All relevant test reports (Validation Documentation)
• Comparison data to devices on the market (Comparison Data)
• Description of the mode of action of the device (Mode of Action)
• Process descriptions of the safety and performance of a device (Safety & Performance Process)
• Reports on clinical investigations (except for devices undergoing SER inspection)
• Information on the status of use abroad

For class IV medical devices, manufacturers must submit the technical documentation in STED format. For classes II (New Devices) and III, submission in STED format is voluntary.

If the technical documentation does not show sufficient equivalence to a device on the market (Comparison Data), the device must undergo a Clinical Data Review (CDR) in addition to the review of the documentation.

Summary and conclusion

The South Korean market represents an interesting market for foreign manufacturers due to the annually growing import rate of medical devices. However, there are some hurdles to overcome:

• Foreign manufacturers need a locally based Korean Licence Holder (KLH) regardless of the medical device class.
• The requirements of KGMP (Korean Good Manufacturing Practices) must be met and certified.
• All necessary documents and files must be submitted in Korean.
• Foreign test reports are only partially accepted.

The level of hurdles depends on the class of the device and, for class II devices, the category of the device.
