KGMP Mock Audit: Top 10 Findings from 12 Foreign Manufacturer Sites

Study Context

Leanabl conducted KGMP mock audits at 12 foreign manufacturer sites in 2024:

Site Profile	Count
US-based (FDA QSR + ISO 13485)	5
EU-based (ISO 13485 + MDSAP)	4
Japan-based (PMDA + ISO 13485)	2
China-based (NMPA + ISO 13485)	1

Total findings across audits: 247. Top 10 recurring issues accounted for 192 findings (78%).

The Top 10 Findings

#1. Korean SOP Coverage Insufficient — 11/12 sites

Korean translations of inspection-critical SOPs missing or incomplete.

Typical gap: 8–15 SOPs in English only; KGMP requires 15–25 Korean SOPs.

Remediation: $15K–$25K translation cost, 4–6 weeks.

#2. Design History File Korean Summary Missing — 10/12 sites

DHF complete in English but lacking Korean executive summary required for inspection trace.

Typical gap: No Korean-language design output summary or design review minutes.

Remediation: $5K–$12K, 2–3 weeks.

#3. Change Control Records Not Tagged to KMD Numbers — 9/12 sites

Change records reference internal product codes without MFDS license cross-reference.

Typical gap: Inspectors cannot trace internal changes to Korean-marketed products.

Remediation: $3K–$8K (process update), 2 weeks.

#4. Open CAPAs Older Than 90 Days — 9/12 sites

Stale CAPAs signal ineffective corrective action to inspectors.

Typical gap: 5–15 open CAPAs older than 90 days at audit start.

Remediation: Close or restart all old CAPAs, 4–6 weeks.

#5. Supplier Quality Records Not Korean-Documented — 8/12 sites

Critical supplier audits and quality agreements in English only.

Typical gap: No Korean trail showing supplier accountability for Korean-marketed products.

Remediation: $4K–$10K, 2–3 weeks.

#6. Complaint Handling Without Korean Timeline Tracking — 8/12 sites

Generic complaint workflow does not flag Korean adverse event timelines (5/15/30 days).

Typical gap: Late adverse event reporting risk for Korean events.

Remediation: $3K–$6K (process update), 1–2 weeks.

#7. Management Review Missing Korean Section — 8/12 sites

Quarterly or annual management review without dedicated Korean market review.

Typical gap: Korean market performance, KLH effectiveness, Korean regulatory changes not reviewed at executive level.

Remediation: Update management review template, 1 week per cycle.

#8. KLH Interface Procedure Undocumented — 7/12 sites

Manufacturer-KLH interactions informal, not documented procedure.

Typical gap: Roles, decision authority, communication frequency not defined.

Remediation: $5K–$10K (procedure development), 2 weeks.

#9. Calibration Records Not Current — 7/12 sites

Equipment calibration overdue or records incomplete.

Typical gap: 3–10 instruments with overdue calibration at audit start.

Remediation: Calibration schedule update, $2K–$5K (per instrument), 1–2 weeks.

#10. Training Records Missing for Korean Documents — 6/12 sites

Staff training records do not cover Korean SOPs.

Typical gap: No training trail for Korean-language documentation users.

Remediation: $3K–$8K, 2 weeks.

Remediation Outcomes

Phase	Duration	Cost
Mock audit	2–3 days	$15K–$25K
Remediation planning	1 week	Included
Critical findings closure	4–6 weeks	$30K–$80K
Verification mock audit	1–2 days	$5K–$10K
Total	6–10 weeks	$50K–$115K

MFDS Inspection Results Post-Remediation

All 12 sites passed MFDS KGMP inspection on first attempt:

Outcome	Count
Passed with zero major findings	9/12
Passed with 1–2 minor findings	3/12
Failed (required re-inspection)	0/12

Compared to industry baseline for foreign sites without preparation:

• First-attempt pass rate without preparation: ~50%
• First-attempt pass rate with structured mock audit + remediation: 100% in this cohort

Cost-Benefit Analysis

Without mock audit:

• 50% probability of failure
• Failure cost: $30K–$80K (re-inspection + remediation + delay)
• Expected cost: $15K–$40K (50% × failure cost)

With mock audit + remediation:

• Mock audit + remediation: $50K–$115K
• ~95% probability of first-attempt pass
• Expected total cost: $52K–$120K

The cost difference is small ($12K–$80K), but the time-to-market benefit is 4–6 months. For products generating $500K+ Korean revenue, mock audit ROI is significant.

Patterns by Site Origin

Origin	Most Common Finding
US (FDA QSR)	#2 DHF Korean summary missing
EU (ISO 13485 + MDSAP)	#1 Korean SOPs insufficient
Japan	#6 Complaint handling Korean timeline
China	#7 Management review Korean section

US and EU manufacturers tend to over-document in English; Asian manufacturers tend to under-document Korean-specific items.

Frequently Asked Questions

Q: How long is a typical mock audit?

A: 2–3 days on-site for the audit + 1–2 days for findings documentation. Leanabl typically provides full report within 1 week of audit close.

Q: Can we use internal staff for mock audit?

A: Yes, if internal team has KGMP expertise (rare for foreign manufacturers). Most clients use external mock audit to get inspector-realistic perspective.

Q: What happens if mock audit finds critical issues?

A: Critical issues drive remediation timeline. For severe issues, KGMP application is delayed until remediation complete (typically 6–10 weeks).

Q: Does Leanabl guarantee inspection pass?

A: No guarantee, but track record speaks: 100% first-attempt pass rate among clients completing full mock audit + remediation program.

Q: When should we schedule mock audit?

A: 8–12 weeks before scheduled MFDS inspection. Allows time for remediation and verification.
