International Medical Device Regulators Forum
Voluntary forum of device regulators — the device counterpart to ICH; its guidance underpins modern QMS, software and post-market frameworks.
What this page does not claim
SPEQ curates and cross-references these bodies. It is not affiliated with, accredited by, or endorsed by any of them, and a count of decoded standards is a measure of SPEQ’s coverage, not of a body’s importance.
WHAT IMDRF COVERS
The International Medical Device Regulators Forum is a voluntary group of medical device regulators formed in 2011 to accelerate international harmonisation and convergence. Its management committee includes the authorities of Australia, Brazil, Canada, China, the European Union, Japan, Russia, Singapore, South Korea, the United Kingdom, and the United States, with the World Health Organization participating as an official observer. It succeeded the Global Harmonization Task Force, which had done the same work from 1992 until it was wound down in 2012.
WHAT IMDRF PUBLISHES
- 01Final documents numbered IMDRF/<working group>/N<nn> — including IMDRF/SaMD WG/N10 (key definitions) and N12 (the risk-categorisation framework)
- 02Adverse event terminology code sets used in device vigilance reporting across participating jurisdictions
- 03Table of Contents and Regulated Product Submission structures for market applications
- 04Working-group guidance on unique device identification, cybersecurity, personalised medical devices, and AI/ML-enabled devices
- 05Consultation drafts opened for public comment before a document is finalised
HOW ITS REQUIREMENTS BITE
IMDRF has no legal authority anywhere. It grants no approvals, issues no certificates, and conducts no inspections. Its documents acquire force only when a member regulator adopts or references them in its own framework — which is why an IMDRF final document is best treated as the shared technical vocabulary a submission is written in, while the binding requirement is always the national instrument. The clearest example is the Software as a Medical Device work, whose definitions and risk-categorisation logic now underpin how several regulators describe and classify software products.
What practitioners get wrong
- An IMDRF document is not law in any jurisdiction — cite the national instrument that adopted it alongside it, never on its own as the requirement.
- The N12 risk categorisation is driven by the significance of the information the software provides and the state of the healthcare situation it addresses, not by technical complexity; using that framing makes a risk argument legible to several regulators at once.
- Do not conflate IMDRF with MDSAP. The Medical Device Single Audit Program is a separate programme run by its participating authorities — Australia, Brazil, Canada, Japan, and the United States — and Health Canada has required MDSAP certification for Class II to IV devices since January 2019.
- Older Global Harmonization Task Force document numbers still circulate and are still cited in some national guidance; check whether an IMDRF document has superseded the GHTF text you are working from.
- Adoption is uneven across members, so the same IMDRF concept can carry different evidentiary weight in two markets — verify per jurisdiction rather than assuming a single harmonised expectation.
WHERE IT SITS INTERNATIONALLY
IMDRF is the device sector's analogue of ICH for medicines, though deliberately looser: it produces harmonised technical documents without a formal adoption pathway binding its members. Its work sits alongside the ISO/TC 210 standards that carry the operational requirements — ISO 13485 for the quality system and ISO 14971 for risk management — while the enforceable regimes remain national, principally EU MDR and IVDR, the FDA Quality Management System Regulation, and Health Canada's medical device regulations. WHO's observer role gives IMDRF outputs reach into markets that rely on reference-regulator decisions rather than running their own full assessments.

IMDRF: frequently asked questions
Reference answers on International Medical Device Regulators Forum’s mandate, what it publishes, and how its requirements acquire force.
What is the IMDRF?
The International Medical Device Regulators Forum is a voluntary group of medical device regulators formed in 2011 to accelerate international harmonisation. Its management committee includes the authorities of Australia, Brazil, Canada, China, the EU, Japan, Russia, Singapore, South Korea, the UK, and the US. It succeeded the Global Harmonization Task Force.
Are IMDRF documents legally binding?
No. IMDRF has no legal authority anywhere — it grants no approvals, issues no certificates, and conducts no inspections. Its documents acquire force only when a member regulator adopts or references them, so cite the national instrument that adopted a document alongside it, never on its own.
Is IMDRF the same as MDSAP?
No. The Medical Device Single Audit Program is a separate programme run by its participating authorities — Australia, Brazil, Canada, Japan, and the US. Health Canada has required MDSAP certification for Class II to IV devices since January 2019. IMDRF’s SaMD work (N10, N12) provides shared vocabulary and risk categorisation.
