KLH vs Distributor-as-License-Holder: Which Risks Your MFDS License?
Choosing your Korea License Holder is a regulatory decision with commercial consequences. The distributor-as-KLH default puts your MFDS license under their control — here's what that means.

The Core Problem
When a foreign manufacturer enters Korea, they face a structural reality: only Korean entities can hold MFDS licenses. The manufacturer must designate either:
Option A: Their Korean distributor as KLH (most common default) Option B: An independent regulatory partner as KLH (Leanabl's model)
Both are legal. The consequences differ significantly.
What Distributor-as-KLH Looks Like
The Korean distributor:
- Holds the MFDS Product License under their name
- Is the legal entity in MFDS records
- Handles all MFDS regulatory correspondence
- Submits change notifications, vigilance reports, renewals
- Negotiates with MFDS during inspections or investigations
This works smoothly until any of the following happens:
- Distributor relationship deteriorates
- Manufacturer wants to switch distributors
- Distributor goes out of business or is acquired
- Distributor demands renegotiated commercial terms
In any of these situations, the distributor holds the license — and the manufacturer faces a 3–6 month license transfer process to extract their own MFDS approval.
The Leverage Asymmetry
Consider a real-world scenario:
A European Class II IVD manufacturer enters Korea with Distributor A in 2022. By 2024, sales have grown 5x and Distributor A demands a 40% margin (up from 25%). The manufacturer wants to negotiate or switch distributors.
Without independent KLH: Distributor A holds the MFDS license. Switching requires: (1) finding new distributor, (2) executing license transfer to new KLH, (3) MFDS approval of transfer (3–6 months), (4) potential gap in market presence during transition.
With independent KLH: The KLH (regulatory partner) holds the license. Distributor changes do not affect MFDS standing. Manufacturer can negotiate freely or switch with minimal regulatory friction.
Comparison Table
| Dimension | Distributor-as-KLH | Independent KLH |
|---|---|---|
| Setup cost | Often "included" in distribution agreement | $5K–$15K initial + annual fee |
| Annual KLH fee | Typically bundled (hidden in margin) | $8K–$25K explicit |
| License transfer cost (if needed) | $15K–$40K + 3–6 months | Not needed |
| Distributor change friction | High (license transfer required) | Low |
| Post-market obligations control | Distributor controls | Manufacturer-directed via KLH |
| Adverse event reporting visibility | Distributor mediated | Manufacturer direct |
| MFDS correspondence access | Distributor mediated | Manufacturer direct |
| Conflict of interest risk | Yes (commercial vs regulatory) | Mitigated (separate roles) |
| M&A flexibility | Constrained (KLH transfer required) | Flexible |
When Distributor-as-KLH Is Acceptable
Distributor-as-KLH can work when:
- Single distributor relationship intended for 5+ years
- Distributor has proven regulatory capacity (vigilance, change management)
- Distributor agreement includes explicit KLH transfer clause favorable to manufacturer
- Manufacturer accepts commercial leverage as cost of market entry
For Class I devices with limited revenue potential, this is often acceptable.
When Independent KLH Is Strongly Recommended
| Scenario | Why Independent KLH |
|---|---|
| Multiple distributors planned | Single KLH covers all distribution relationships |
| Anticipated revenue >$1M/year | Cost of KLH << cost of distributor leverage |
| Class II+ device with growth runway | License is a strategic asset |
| Frequent product variants or changes | Direct MFDS correspondence speeds change notifications |
| M&A target or acquirer | KLH transfer at exit adds $50K+ to deal complexity |
| Multiple Korean markets (hospital + retail + e-commerce) | Single license, multiple distribution channels |
The Hidden Cost of "Free" KLH
Distributors offering "free" KLH service typically:
- Bundle KLH cost into commercial margin (effective cost: $20K–$60K/year for $1M revenue distributor)
- Reserve right to charge license transfer fee ($15K–$40K) if relationship ends
- Limit manufacturer's direct MFDS access (responses filtered through distributor)
- Receive MFDS correspondence first — manufacturer learns of issues days/weeks later
True cost analysis: For $1M+ annual revenue, independent KLH ($10K–$20K/year) is typically cheaper than distributor-bundled KLH.
How License Transfer Works (If You Need to Switch)
If you currently use distributor-as-KLH and want to transition to independent KLH:
- Pre-negotiation (2–4 weeks): Review existing distributor agreement for KLH transfer clauses, exit terms, and notice periods
- New KLH engagement (1–2 weeks): Execute services agreement with independent KLH (e.g., Leanabl)
- MFDS license transfer filing (4–6 weeks): KLH-to-KLH transfer submitted to MFDS
- MFDS review and approval (8–12 weeks): MFDS verifies new KLH capacity and approves transfer
- Post-transfer integration (2–4 weeks): Vigilance, change notification, and renewal workflows transition to new KLH
Total: 4–6 months. During this period, the device remains marketable under the existing license.
Frequently Asked Questions
Q: Can the manufacturer be the KLH directly?
A: No. Only Korean-registered entities can be KLH. Foreign manufacturers must appoint a Korean entity (distributor or independent service).
Q: Can we have multiple KLHs for different products?
A: Yes. Each MFDS Product License has one KLH, but a manufacturer can use different KLHs for different products or product lines.
Q: What's the typical Leanabl KLH annual fee?
A: $8K–$25K depending on product complexity, number of variants, and post-market obligations volume. Pricing is disclosed upfront with no margin bundling.
Q: If we switch from distributor-KLH to Leanabl-KLH, do we lose our distributor?
A: No. The KLH role (regulatory license holder) is separate from the distributor role (commercial seller). You can keep the distributor for sales while transferring KLH to Leanabl for regulatory standing.
Q: What happens to our MFDS license if Leanabl goes out of business?
A: Leanabl maintains a license-transfer succession plan. In the unlikely event of business cessation, your MFDS license transfers to a designated successor KLH or back to a manufacturer-designated entity. Specific terms are in the KLH services agreement.
