KLH vs Distributor-as-License-Holder: Which Risks Your MFDS License?

6 min read

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.

KLH vs Distributor-as-License-Holder: Which Risks Your MFDS License?

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.

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:

  1. Pre-negotiation (2–4 weeks): Review existing distributor agreement for KLH transfer clauses, exit terms, and notice periods
  2. New KLH engagement (1–2 weeks): Execute services agreement with independent KLH (e.g., Leanabl)
  3. MFDS license transfer filing (4–6 weeks): KLH-to-KLH transfer submitted to MFDS
  4. MFDS review and approval (8–12 weeks): MFDS verifies new KLH capacity and approves transfer
  5. 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.
