MFDS License Transfer in Medical Device M&A: 6-Month Reality Check
Acquiring a Korean medical device product line means inheriting MFDS license transfer timelines. Plan for 3–6 months between deal close and effective KMD control.

The M&A Regulatory Reality
When a medical device company acquires a Korean product line, three things must happen:
- Commercial transfer: Sales rights, distributor agreements, customer relationships (immediate at deal close)
- MFDS regulatory transfer: Product license transferred between KLHs (3–6 months)
- KGMP transfer: Manufacturing site KGMP certification transferred or re-issued (6–12 months if manufacturing site changes)
Many deals plan only for #1. The regulatory and KGMP timelines drive most post-close friction.
License Transfer Timeline Breakdown
| Phase | Duration | Activity |
|---|---|---|
| Pre-filing preparation | 2–4 weeks | Diligence on existing license, transfer agreement drafting |
| MFDS pre-consultation | 1–2 weeks | Optional but recommended for complex products |
| Filing | 1 week | Transfer application submitted via new KLH |
| MFDS administrative review | 2–4 weeks | Completeness check |
| MFDS substantive review | 6–12 weeks | License continuity verification |
| Approval and KMD update | 2–4 weeks | Updated KMD certificate issuance |
| Post-transfer integration | 2–4 weeks | Vigilance, change notification, renewal workflow transition |
| Total | 3–6 months |
Pre-Deal Regulatory Diligence
Before signing, acquirers should verify:
License Validity
- ✅ KMD number active and not under suspension
- ✅ License renewal date confirmed (3-year cycle)
- ✅ No outstanding MFDS deficiencies or warnings
- ✅ Change notifications up to date
- ✅ Vigilance reporting compliance verified
KGMP Status
- ✅ KGMP certificate valid for manufacturing site
- ✅ KGMP renewal date confirmed
- ✅ No outstanding KGMP findings
- ✅ Surveillance audit status current
KLH Capacity
- ✅ Current KLH legal entity status verified
- ✅ KLH service agreement transferability confirmed
- ✅ Post-market data accessibility post-transfer
- ✅ Distributor agreement KLH clauses identified
Documentation Status
- ✅ Korean STED current and accessible
- ✅ Korean labels and IFU in current format (MFDS Notice 2022-110 compliance)
- ✅ Clinical evidence files retained
- ✅ Adverse event records 5+ years retained per Korean law
Transition Service Agreement (TSA) Structure
For deals where regulatory transfer extends past commercial transfer, structure TSA covering:
Mandatory TSA Elements
| Element | Why |
|---|---|
| Existing KLH continues filing through transfer date | Maintains license validity |
| Vigilance reporting continues under seller's KLH | Avoids reporting gaps |
| Change notification freeze during transfer | Prevents complications |
| Adverse event escalation protocol | Defines responsibility during transition |
| MFDS correspondence routing | Ensures both parties informed |
| TSA termination triggers | Defines end of seller's obligations |
Typical TSA Duration
- Standard product transfer: 4–6 months TSA
- Complex portfolio (10+ products): 6–9 months TSA
- Manufacturing site change required: 12+ months TSA
Three Common M&A Mistakes
Mistake 1: Closing Without License Transfer Plan
Closing the commercial deal without an executed license transfer plan creates a regulatory limbo:
- Seller's KLH retains MFDS responsibilities
- Acquirer cannot file change notifications or vigilance reports
- Distributor relationships unclear
- Customer warranty claims confused
Fix: License transfer filing must be ready to submit within 30 days of close.
Mistake 2: Underestimating KGMP Implications
If acquirer plans to move manufacturing to a different site:
- New site requires KGMP inspection (6–12 months)
- Existing license tied to original site
- License modification required
- Possible market gap during site transition
Fix: Either keep manufacturing at original KGMP-certified site, or plan 12–18 months for KGMP transfer.
Mistake 3: Independent KLH vs Distributor KLH Confusion
If the seller used distributor-as-KLH (and is also selling the distributor relationship):
- License transfer is more complex
- Distributor agreement and KLH agreement intertwined
- Risk of distributor blocking or delaying transfer
Fix: Restructure to independent KLH before deal close, if possible.
Cost Estimates
| Cost Component | Range |
|---|---|
| Pre-deal regulatory diligence | $10K–$30K |
| License transfer filing (per product) | $8K–$20K |
| MFDS official fees (transfer) | $500–$2K per license |
| New KLH setup (if changing) | $5K–$15K |
| Korean legal counsel | $15K–$50K |
| TSA management | $5K–$15K/month |
| Total (single product) | $50K–$150K |
| Total (portfolio of 10 products) | $150K–$500K |
Deal Structuring Recommendations
For Acquirers
- Diligence early: 6–8 weeks of regulatory diligence before LOI
- Quantify KGMP implications: Manufacturing site changes drive 12-month timelines
- TSA budgeting: Plan 6–9 months of TSA costs into deal economics
- Engage Korean regulatory counsel: Korean lawyers + regulatory consultants are essential
- Independent KLH transition: If seller uses distributor-KLH, plan to transition to independent KLH at close
For Sellers
- Pre-clean regulatory status: Resolve outstanding deficiencies before listing
- Structure to independent KLH: Maximizes transferability and deal value
- Document Korean operations: Korean records often informal; formalize before diligence
- License renewal timing: Avoid selling within 6 months of renewal date
- Transition cost transparency: TSA costs are negotiable; underwrite them in valuation
Frequently Asked Questions
Q: Can we sell devices in Korea immediately after deal close?
A: Yes, under the seller's KLH during the transition period. The license remains valid; only the KLH role transfers later.
Q: What if MFDS denies the license transfer?
A: Denials are rare (<5% of cases) when filing is complete. Most denials trace to incomplete diligence (outstanding deficiencies, KGMP issues). If denied, the existing license remains under seller's KLH until corrective action.
Q: Does Leanabl handle license transfers?
A: Yes. Leanabl's License Transfer & RA Due Diligence service covers pre-deal diligence through post-transfer integration.
Q: Can we transfer KGMP if we keep the same manufacturing site?
A: Yes, KGMP certificates transfer with site control. If acquirer takes operational control of the manufacturing site, the KGMP certificate transfers as part of the asset.
Q: How does Leanabl charge for portfolio transfers?
A: Per-product fixed-fee plus optional TSA management. For 10+ product portfolios, volume discounts apply. Typical 10-product transfer runs $150K–$300K all-in.
