ISO 13485 and FDA QMSR: what buyers should verify
Since 2 February 2026, FDA 21 CFR Part 820 is the Quality Management System Regulation (QMSR), incorporating ISO 13485:2016 by reference.
Related requirements, different evidence
ISO 13485 certification and FDA regulatory compliance are different claims. Incorporation of the standard does not turn an ISO certificate into FDA approval, registration or a guarantee of compliance with all applicable US requirements.
Check the role of the manufacturer
FDA describes QMSR applicability for finished device manufacturers. Establish whether the manufacturer is a component maker, finished device manufacturer or another regulated operator. Define the quality agreement and evidence needed for that role.
Ask for identifiable documents
Request the certificate holder, manufacturing site, scope, number, issuing body and validity status. For US supply, identify the applicable QMSR obligations and evidence. A single routine certification audit does not automatically replace FDA inspection or establish product authorization.
Before requesting a quote
Send the drawing revision, application, material preference, critical dimensions, annual quantity, delivery market and required evidence. Feasibility, testing, price and timing need written project review.
Buyer questions
Does EU MDR require every supplier to hold an ISO 13485 certificate?
Do not make that blanket claim. The European Commission describes use of harmonised standards as voluntary; applicable legal duties and contractual supplier requirements must be assessed separately.
