ISO 13485 Certification — Does it Substitute?
Japan's formal position
ISO 13485 certification issued by a third-party accredited certification body does not formally substitute for MO 169 compliance or for a PMDA QMS inspection. The legal requirement under the PMD Act is compliance with MO 169, verified through the PMDA inspection process.
MHLW has not issued a formal mutual recognition or equivalence decision between ISO 13485 and MO 169.
Practical use of ISO 13485 in PMDA inspections
In practice, ISO 13485:2016 certification provides significant practical advantages in PMDA inspections:
-
Demonstrates QMS maturity. PMDA inspectors view ISO 13485 certification favourably — it indicates that the site has had its QMS assessed by an independent third party.
-
Reduces audit duplication. PMDA inspectors typically review the ISO 13485 certificate and recent audit reports at the start of the inspection. For well-documented compliant sites, PMDA may focus its inspection on MO 169-specific requirements rather than re-auditing areas already well-covered by ISO 13485 audits.
-
Provides evidence for gap analysis. The audit non-conformances from ISO 13485 audits, and how they were resolved, are directly relevant to PMDA's assessment of the CAPA system.
Gaps to address even with ISO 13485 certification
Regardless of ISO 13485 certification status, sites supplying devices to Japan must specifically address:
- MAH quality oversight documentation — the manufacturer's contract with the MAH and the system for reporting post-market information to the MAH (MO 169-specific requirement)
- Japanese labelling controls — document control covering the approved Japanese labelling (Shonin/Ninsho approved text)
- GPSP interface — how the manufacturer receives and transmits complaint/adverse event information to the MAH for GPSP purposes
- Japanese regulatory documentation — FMR certificate, Japanese approval/certification documents, controlled as quality records
