Importing Intraoral Scanners into South Korea — A Practical Registration Guide

Key takeaway — A CE mark does not shorten the Korean path; the process starts over. Intraoral scanners are normally reviewed within the Class II range, and the review asks one question: "does this device scan the oral cavity accurately and safely?" In practice the bottleneck is rarely the testing itself — it is getting documents out of the Chinese manufacturer on time.

What class is an intraoral scanner?

An intraoral scanner (dental 3D scanner) captures the inside of the mouth optically and builds a three-dimensional impression dataset. Item classification and class are determined from the annex to the MFDS (Ministry of Food and Drug Safety, formerly KFDA) notification Regulation on Medical Device Items and Their Classes, and in Korea these devices are normally reviewed within the Class II range. The overall procedure follows the same shape as the Class II certification guide.

One caution, though. With identical hardware, what the software claims to do can change the scope of review. Go beyond simply capturing and displaying geometry — into caries detection, orthodontic analysis, or anything else that supports a diagnostic judgment — and the product may fall into a separate item or a higher review track. Fixing your intended-use wording early and locking down the classification is what governs the whole timeline.

There is a useful shortcut for the classification call: search the MFDS medical device database for already-registered products using the same technology and read across their item names, classes, and intended-use statements. Several intraoral scanners are already distributed in Korea, so placing those precedents next to your own specifications will filter out classification risk at the start.

The import roadmap: three gates

Import registration is not a queue — the key is designing it in parallel. There are three gates, and the more they overlap, the shorter the total timeline.

Gate	Content	Practical point
Import business license	Qualifying as an importer, appointing a quality manager	Can be started independently of the product — begin here
Product certification	Technical documentation review (Class II is normally delegated to a private review body)	Test reports are the critical path
KGMP	Import KGMP conformity assessment (including the overseas site)	Manufacturer cooperation and audit scheduling are the bottleneck

Class II certification typically takes around 3 to 4 months. Testing time and the KGMP audit sit on top of that, so the standard strategy is to have testing commissioned and KGMP preparation already running before you file for product certification. This matters most for import KGMP involving an overseas site, where the manufacturer's response speed dictates the schedule. "Let's start KGMP once the certificate is issued" is simply a decision to push your launch date back by that much.

Test data: the four axes the review looks at

1. Electrical/mechanical safety and EMC — IEC 60601-1 and IEC 60601-1-2 (EMC) are the baseline. Because the device is handpiece-shaped, the definition of the patient-contacting applied part and the insulation design become review points.

2. Software — 3D reconstruction software requires software lifecycle documentation per IEC 62304. Version control is especially critical here. Chinese manufacturers frequently push firmware and application updates, and if the version tested differs from the version filed, that discrepancy alone triggers a deficiency. If the device connects to a network or cloud service, assess the likelihood of cybersecurity documentation being requested as well.

3. Biological safety — The scanner tip contacts oral mucosa. You must classify contact site and duration under the ISO 10993 series and provide evaluation data such as cytotoxicity; if the tip is sterilized and reused, the scope widens to reprocessing (cleaning and disinfection) validation data. All of this rests on raw material information for the tip — and Chinese manufacturers frequently do not hold upstream supply chain documentation themselves, so confirm what they can actually produce before signing.

4. Optical safety — An intraoral scanner emits light inside the mouth, so photobiological safety evaluation may be required. The applicable standard and the depth of evaluation depend on the light source specification (wavelength, output, exposure mode), so obtain the manufacturer's light source datasheet early and settle the evaluation scope first. Of the four axes, this is the one practitioners miss most often.

Alongside these, ISO 14971 risk management documentation and IEC 62366-1 usability engineering documentation form the backbone of the technical documentation.

How far does CE documentation actually travel?

CE technical documentation is an excellent starting point, but it does not substitute for the Korean review. In practice the split looks like this.

• Likely usable — Internationally recognized test data, such as IEC 60601 series reports issued under the IECEE CB scheme and ISO 10993 series test reports. Acceptance conditions and validity management vary by product and by document, so check the screening criteria in the guide to using foreign test reports.
• Reference only — The CE certificate itself, the EU Declaration of Conformity (DoC), and clinical evaluation reports written solely to European requirements. These need to be rebuilt against Korean review requirements.

Building your schedule around "we have CE, so it's just paperwork" is how timelines slip. The first job is screening each report against Korean acceptance criteria. Doing that screening before you sign carries a second benefit: how many test items are missing determines your upfront investment, which gives you an evidence-based position when negotiating terms with the manufacturer (document supply obligations, how testing costs are shared).

What to get from your Chinese manufacturer

In imports from China, the point that most often collapses is not technical — it is communication. Four items belong in the contract in writing.

• Letter of authorization (LOA) — A manufacturer-signed document delegating Korean registration authority to the importer. Settle exclusive versus non-exclusive terms in the same document.
• ISO 13485 certificate — The baseline evidence of the site's quality system and the starting document for the KGMP audit.
• Raw technical documentation — Specifications, circuit and structural drawings, material information (including the tip contact surface), and original test reports. A manufacturer who says "we will only send summaries" is a manufacturer you will get stuck with mid-review.
• KGMP audit cooperation — A commitment to submit overseas site documentation and, where necessary, accommodate an on-site inspection. If cooperation stops at the audit stage, there is no fallback.

One more practical tip: make your document requests as a document list table. Ask a Chinese manufacturer to "send the technical data" and what arrives is usually catalog-grade material. Build a table of the exact document names, versions, and languages you need, attach it to the contract, and set response deadlines — that alone removes a large share of the gaps that surface during review. Customs clearance and distribution work after registration is covered in a separate article; this one stays focused on the path to obtaining the license.

Configuration design: how much to include in the registration

Intraoral scanners are never sold as a bare unit. Scanner tips (replaceable), calibration tools, cradles, dedicated cables, and operating software all move as one set. In an import project you need to decide early how much of that set goes into the registered configuration.

Bundled components can be imported and sold together with no separate procedure, but each one's specifications and test scope must be reflected in the technical documentation. Conversely, an accessory left out of the configuration may later require a change procedure or a separate review to bring in. This matters most for replaceable tips that touch the oral cavity directly: their material and reprocessing data are reviewed together with the main unit, so it is safer to register every tip variant in your sales plan from the outset. Whether to include general-purpose equipment such as PCs and monitors is another question to settle in line with how the manufacturer's manual defines the configuration.

Common reasons for rejection and deficiency notices

• Claimed functions inconsistent with the item classification (advertising analytical or diagnostic functions while filing as a simple scanner)
• Insufficient material information for the scanner tip contact surface; gaps in the scope of biological safety evaluation
• The standard version behind a CE test report not matching Korean acceptance criteria
• IEC 62304 software documentation inconsistent with the version and functional specifications (version tested ≠ version filed)
• Light source specification data too thin to define the scope of optical safety evaluation
• Manufacturer name and address inconsistent across the certificate, test reports, and LOA (mixed English transliterations of Chinese manufacturers)

Checklist before you start

• Item classification and class confirmed; software claim wording fixed
• Import business license status confirmed — if not held, start immediately
• List of the manufacturer's existing test reports obtained → screened against Korean acceptance scope
• LOA, ISO 13485, and raw technical documentation supply written into the contract
• Material and reprocessing documentation for the scanner tip secured
• Plan in place to commission domestic testing for the missing test items
• KGMP audit schedule and product certification filing designed to run in parallel
