We Have CE Marking — Does That Cover Medical Device Registration in South Korea?

Key takeaway — There is no mutual recognition between CE marking and MFDS approval. Holding CE marking does not let you skip a single step of the Korean process. But while the regimes are separate, the documentation is reusable. How much of your CB reports, GLP reports, and CE technical file you can carry over determines most of your preparation time — and that judgment only comes out right if you work in this order: document inventory first, gap analysis second.

Separate regimes, reusable documentation — that one line is the whole story

This is the question importers ask most often: "Our manufacturer holds CE marking — can we start selling in Korea right away?" The answer is clear. No. CE marking is a European market-access requirement; selling in Korea requires separate notification, certification, or approval from the MFDS (Ministry of Food and Drug Safety, formerly KFDA). There is no agreement under which Europe or the United States and Korea recognize each other's medical device registrations. The same applies to FDA clearance or approval.

Not even the classification carries over automatically. A device that is Class IIa in the EU is not guaranteed to be Class II in Korea. Korean classification has to be re-confirmed against the MFDS product classification system, and the class then determines whether you file a Class I notification, a Class II certification, or a Class III / Class IV approval. The differences between the three routes are set out in the procedure overview guide.

The holder of the registration is different too. Under CE marking the manufacturer declares conformity and appoints a European authorized representative; in Korea, registration of an imported device is issued in the name of the Korean importer. In practice that difference bites hard, because the source documents the review requires mostly sit in the manufacturer's vault, and the importer is the party that has to extract them. Agreeing a documented framework for manufacturer cooperation early on sets the pace for every stage that follows.

None of which is cause for discouragement. Holding CE marking means the manufacturer has already been through a full round of testing and documentation built on international standards — IEC 60601-1, the ISO 10993 series, ISO 14971. The Korean review is built on the same international standards, so the question is never "will this be accepted" but "under what conditions is this accepted."

How far foreign test reports are accepted

Alongside reports from registered Korean testing laboratories, the MFDS accepts reports from two internationally recognized routes.

Test area	Accepted route	Practical conditions
Electrical and mechanical safety (IEC 60601-1)	CB test report issued by an NCB under the IECEE CB Scheme	The standard edition must align with the Korean common standards
Electromagnetic compatibility (IEC 60601-1-2)	CB test report	Same as above. Edition mismatches are especially common with EMC
Biological safety (ISO 10993 series)	Report from an OECD GLP test facility	Confirm the GLP compliance statement; contact type and duration categories must match the Korean assessment
Performance testing	Varies by product	Where a Korean product-specific standard exists, its test items and conditions must be met

One caution. "The reports we used for CE marking" and "CB test reports" are not the same thing. A test report that a European Notified Body accepted may fall outside the CB Scheme, and if so it may not be eligible for acceptance in Korea. Check the cover page for the CB mark and the issuing NCB first. The detailed acceptance requirements for each report type are covered separately in the guide to acceptance of foreign test reports.

Four patterns that generate additional testing

Run the gap analysis and additional testing almost always traces back to one of four situations.

1. Items unique to a Korean product-specific standard — For some product categories, the MFDS standard requires test items that do not exist in the international standard, or applies different acceptance criteria. No amount of existing reports closes this gap, so check it first.

2. Mismatch in test conditions or model — If the sample tested for CE marking differs from the model being imported into Korea — a derivative model, a different accessory configuration, a different rated voltage — the report's representativeness comes into question. Sometimes a written justification of the differences resolves it; sometimes difference testing is required.

3. Age of the report — For reports issued some time ago, the review typically also asks for documentation demonstrating that the product has not changed since testing. This is where the manufacturer's change control records earn their keep.

4. Standard edition differences — A report run against an older edition may require a difference analysis against the edition referenced by the Korean common standards, or difference testing. EMC is where this comes up most often.

If the product contains software, one more item attaches: software life cycle documentation based on IEC 62304, plus cybersecurity documentation where the device has communication functions. Even when documentation exists from the CE process, it typically has to be reorganized to match the Korean submission format and level of detail. For sterile products, sterilization validation documentation under ISO 11135 (EO sterilization) or ISO 11137 (radiation sterilization) and sterile barrier packaging documentation under ISO 11607 go through the same kind of review.

CE technical file to Korean technical documentation: reconstruction, not translation

The second common misconception lives here. "We can just translate the CE file, right?" — No. A CE technical file is a body of conformity evidence organized around the GSPR (General Safety and Performance Requirements) checklist. Korean technical documentation is a form-based document that fills in the items prescribed by the Regulation on Approval, Notification and Review of Medical Devices — intended use, principle of operation, performance, raw materials, directions for use, and so on. The structures are different, so map the items first, then rewrite to the Korean format.

In real projects, the time sink is not translation but locating information. The details the Korean format demands — raw material specifics (chemical names and specifications of patient-contacting materials), the rationale behind storage conditions and shelf life, the traceable link between each test standard and its report — are scattered across the CE technical file, or exist only in the manufacturer's internal design documents. Build a mapping table and you can see at a glance that "this item in the Korean form comes from that file, that page, in the CE documentation" — and every blank cell becomes a line on your document request list to the manufacturer. For item-by-item drafting guidance, see the practical guide to writing technical documentation.

The working sequence: inventory first, gap analysis second

Following the sequence is what makes it fast.

Step 1 — Document inventory. Tabulate everything the manufacturer holds: document title, issuing body, applicable standard and edition, issue date, and the model tested. "We have CE" is not an inventory; you have to go down to the individual document.

Step 2 — Korean requirements matrix. Fix the product classification and class, then pull the required test list from the applicable product-specific standard and the common standards.

Step 3 — Gap analysis. Compare the two tables and sort each item into "accepted as-is / needs supporting justification / requires retesting." Only once the retest items are fixed can you commission testing and build a schedule.

It is worth saying what happens when you run the sequence backwards. Commission testing before taking inventory and you either duplicate tests for items already covered by an acceptable CB report, or you enter the review missing the very Korea-specific item you needed and come back out on a deficiency letter. Both cost months, not weeks. The gap analysis is a day or two of desk work — and that day or two is what protects the entire testing schedule.

For an import project, you also need to run KGMP (import) preparation as a parallel track to compress the overall timeline. ISO 13485 certification makes KGMP (Korean Good Manufacturing Practice) preparation easier, but here too it is not an automatic acceptance.

Common reasons for rejection and deficiency letters

• The standard edition in the CB report does not match the edition referenced by the Korean common standards
• Biological safety reports submitted without a GLP compliance statement
• The model name on the test report does not match the model applied for, with no justification of the difference
• Submitting a translated CE technical file as-is, leaving mandatory items in the Korean format blank
• Missing no-change justification for older test reports
• Assuming the EU class carries over and choosing the wrong route (filing an approval for a certification item, or vice versa)

Checklist before you start

• Confirm the Korean product classification and class — do not take the EU class at face value
• Build an inventory of the manufacturer's test reports (standard edition, issuing body, issue date, model tested)
• Verify on the cover page whether each report is CB or GLP
• Check whether a Korean product-specific standard exists for the category, and what unique test items it carries
• Build a mapping table: CE technical file to Korean technical documentation, item by item
• List every difference between the tested model and the imported model (derivatives, accessories, ratings)
• Plan a parallel KGMP preparation track for the import license
