Medical Device Parts. Built to ISO 13485 + QMSR

Medical Device Manufacturing FAQ

Q1: What is the difference between ISO 13485 and QMSR, and do you comply with both?

QMSR took effect February 2, 2026. It rewrites 21 CFR Part 820 by incorporating ISO 13485:2016 by reference, replacing the legacy QSR. A manufacturer running a current ISO 13485:2016 system with CNC machining explicitly in scope satisfies the QMSR framework. The two now point to the same requirements.

Suppliers who held the old QSR qualification without ISO 13485 have gaps to close, particularly around risk management documentation under ISO 14971 and Device History Record format. Our quality system runs under ISO 13485:2016 with CNC machining and injection molding in scope on the certificate. That scope covers the processes that produce your parts, not just design or assembly functions. If your qualification checklist asks for a QMSR gap assessment or transition documentation, request it from our quality team when you submit the RFQ. You can verify our ISO 13485:2016 certificate on the Quality & Certifications page

Q2: Can you supply parts for Class III devices, and what changes compared to Class I or Class II work?

Class I and Class II non-sterile, non-implantable components are standard scope. Select Class III programs are accepted after reviewing the specific device, the component function, and the regulatory submission pathway.

Documentation depth changes at each tier. Class I non-exempt parts ship with a Certificate of Conformance and dimensional report. Class II adds material traceability to heat and lot level, ISO 10993 biocompatibility documentation for patient-contact materials, and a full CMM dimensional layout tied to the first article. Class III implantables add process validation records covering IQ, OQ, and PQ, sterility packaging controls where applicable, and a Device History Record package auditable by FDA without gaps. If the device sits on the PMA pathway rather than 510(k), bring the DHF scope to the first conversation so tooling, process validation, and documentation costs go into the original quote

Q3: How do you handle material traceability, and how long are records retained?

Every material order arrives with a mill certificate tied to a specific heat number. That heat number gets logged on the work order at receiving, follows the stock through machining, and goes onto the container label or part marking at final inspection. Each lot shipped carries a Device History Record containing the FAI, in-process inspection records, the mill certificate, and any non-conformance reports.

Retention runs 7 years minimum from the manufacture date for standard medical device components, per ISO 13485. For implantable or life-sustaining device parts, retention extends to 10 years or beyond depending on device classification or customer quality agreement terms. Traceability requirements need to go into the RFQ at the start. Documentation setup, labeling format, and incoming inspection steps affect both cost and lead time. Defining those upfront avoids re-quotes later.

Q4: Which materials do you run for medical applications, and how is biocompatibility handled?

Standard machined stock: 316L stainless for fluid path parts, surgical instruments, and housings; Ti-6Al-4V ELI (Grade 23, ASTM F136) for implant-grade work where standard Grade 5 does not qualify under FDA guidance; PEEK for radiolucent housings, spinal components, and dental milling blanks; PC and PC/ABS in UL94 V-0, ISO 10993-5 and ISO 10993-10 tested grades for device enclosures and patient-adjacent housings.

Biocompatibility gets evaluated per ISO 10993-1 based on contact type (surface, externally communicating, implant) and duration (limited under 24 hours, prolonged up to 30 days, permanent). The same base polymer exists in both industrial and medical-certified formulations. We supply materials with the certifications your regulatory submission requires, but the Biological Evaluation Plan and Report sit inside your DHF. Under QMSR, biocompatibility cannot be treated as a late-stage submission task. It needs to be defined as a design input at the start of the program, which affects which material grade we order and what mill cert format ships with the stock.

Q5: What documentation ships with every medical device order?

Standard shipment package: Certificate of Conformance, CMM dimensional report, material mill certificate with heat and lot number, surface finish report where Ra is called out on the drawing. For Class II programs and above, the FAI gets built during the first production run and archived against the specific drawing revision.

On request: PFMEA and control plan documentation, Gage R&R study results, in-process SPC data on specified dimensions, passivation validation records for stainless parts, and IQ/OQ/PQ records for validated processes. The cleaner path is listing documentation requirements in the purchase order, not requesting them after parts ship. Post-ship documentation requests add cycle time and hold up your receiving acceptance.

Q6: My program has a tight design-freeze window. What lead times can you hold?

CNC prototype samples from an approved STEP file: 7 business days. That covers aluminum, 316L, and Ti-6Al-4V ELI across most geometries. PEEK and specialized medical-grade polymers add 2 to 5 days depending on stock availability.

For injection-molded housings, soft aluminum tooling with T1 samples runs 3 to 4 weeks. If the design is still moving, vacuum casting off a machined master gives you production-representative parts in medical-grade PC or polyurethane without tooling commitment. Once geometry is frozen, steel production tooling runs 8 to 12 weeks.

510(k) programs in 2024 hit a median FDA review time of 177 days. The manufacturing constraint that actually slips programs is not prototype lead time. It is FAI and documentation completeness at first article. We build the DHR documentation alongside first-article machining. That means your first article ships with a complete package ready for your records, not a follow-up email three weeks later
