Start with what your products require
The right medical device 3PL is the one whose controls match your products, channels and quality system, not the one with the lowest pick fee. Before you send a single RFP, write down what your products actually require.
- Device classes and whether any items are sterile, implantable, serialized or expiry-dated
- Labeled storage conditions, including any refrigerated or controlled-room-temperature items
- Hazardous materials, most often lithium batteries in powered devices
- Channels: hospitals and health systems, clinics, distributors, DTC, marketplaces
- Activities beyond storage and shipping, such as kitting, relabeling or importing
That list becomes your requirements matrix. It also tells you early whether you need a provider with FDA-registered facilities, which depends on activities like relabeling and repackaging rather than on storage alone. Many brands skip this step, choose a general ecommerce warehouse, and discover the gaps during their first audit or their first recall.
Traceability is the non-negotiable
Ask every candidate to show you, live in their warehouse management system, how a single unit is traced from receipt to consignee. A medical device 3PL should capture lot, serial and expiration data at receiving, ideally by scanning the UDI barcode rather than keying it, and verify it again at picking and packing.
Then ask the question that matters most: if we called you today about lot 12345, how long would it take to give us every consignee who received it, with quantities and ship dates? A credible answer is a query that runs in minutes and a report delivered the same day. An answer that involves exporting orders and matching them against receiving logs means traceability lives at the SKU level, which is not good enough for devices.
Also confirm that the system supports FEFO allocation, minimum remaining shelf-life rules per customer, and system-enforced holds that physically block allocation.
Quality system fit and the quality agreement
FDA's Quality Management System Regulation, which incorporates ISO 13485:2016 by reference and took effect in February 2026, expects manufacturers to control the suppliers whose work affects product quality. For most device companies, a 3PL that stores and ships finished devices is one of those suppliers.
That makes the quality agreement the backbone of the relationship. It should define responsibilities for receiving inspection, storage conditions, holds and releases, nonconformance handling, deviations, change notification, complaint handoff, recall support, record retention and audits. Ask candidates for their standard quality agreement template, their written procedures and their training records approach. A provider that has never signed a quality agreement, or treats it as a formality, is telling you something.
Ask too whether they will host your supplier audits and how they handle findings. You want a partner that responds with corrective actions, not one that argues.
Storage conditions and monitoring
Verify that the provider can store every product within its labeled conditions in the markets you need. For ambient products, ask about temperature and humidity monitoring, pest control, cleanliness and how product is kept off the floor and away from heat sources. For temperature-sensitive products, ask for the monitoring system, alarm escalation, calibration schedule, mapping results and their excursion procedure.
The excursion procedure is the tell. A good one places affected stock on hold automatically, reports the zone, duration and readings to you, and waits for your quality team's disposition. A weak one lets a warehouse supervisor decide that a few hours over range is fine. Only the manufacturer has the stability data to make that call.
Finally, confirm which markets offer refrigerated storage. Cold-chain items often need to be concentrated in fewer locations than ambient items, and that affects your network design.
B2B healthcare shipping capability
If you sell to hospitals, surgery centers, clinics or distributors, test the provider's B2B capability as hard as their ecommerce capability. Health system receiving docks reject shipments without purchase order numbers, accurate packing lists and readable carton labels, and distributors often charge back for ASN errors.
Ask which EDI documents they support, such as 850, 855, 856 and 810, and whether they can carry lot and serial detail in the advance ship notice. Ask whether they print GS1 SSCC labels tied to ASNs, how they handle dock appointments and LTL, and whether they can deliver to clinics without docks using liftgate or inside delivery.
If your field sales team carries trunk stock or you run loaner kits, ask how those flows are tracked. Field inventory is where traceability most often breaks down, and the 3PL should be able to show you exactly which units each rep holds.
Returns, complaints and recalls
Medical device returns are where generic warehouses do the most damage. Ask how returns are received and whether they go to quarantine before inspection. Ask what criteria decide whether a unit can be restocked, and confirm that sterile or single-use products with any packaging compromise are never returned to stock.
Complaint handoff is equally important. When a customer returns a device and reports that it malfunctioned, that is potentially a complaint your team must evaluate, and possibly a Medical Device Report under 21 CFR Part 803. The 3PL must recognize it, flag it and send it to you with the order, lot, serial and photos.
For recalls, ask whether the provider will run a mock recall during onboarding. Timing their hold, consignee report and reconciliation steps on a real lot is the fastest way to separate claims from capability.
Questions to ask before you sign
Use this short list in your final round of conversations:
- Show me a consignee report for a lot or serial in your system right now.
- How are holds enforced, and who can release them?
- What is your excursion procedure, and who decides disposition?
- Which of your facilities are FDA-registered, and for which activities?
- Will you sign our quality agreement, and how do you notify us of changes?
- How do you route returns that report a malfunction?
- Which markets offer refrigerated storage?
- What EDI documents and label formats do you support?
- How do we get our records back if we leave?
The last question is easy to overlook. Your distribution records are part of your quality records, and you may need them for years. Agree on retention, export formats and transfer before you sign, so your data never becomes stranded.
Making the decision
Score each candidate against the requirements matrix you built at the start, weighting traceability, quality system fit and recall readiness above price. A provider that is cheaper per order but cannot produce a same-day consignee report, or will not sign a meaningful quality agreement, will cost far more the first time something goes wrong.
Then look at network fit. Medical customers are spread across the country, and positioning inventory in two or three well-chosen markets can bring most hospitals and patients within one to two days by ground. Ask candidates to model transit times from their markets to your actual customer addresses.
Finally, pressure-test onboarding. Ask for a written implementation plan covering item master setup, lot and serial rules, integrations, quality agreement execution, initial inventory receipt and a mock recall. A provider that can describe onboarding precisely usually runs operations the same way.
Frequently asked questions
What should I look for in a medical device 3PL?
Look for lot, serial and expiry capture at every touch, FEFO allocation, system-enforced holds and quarantine, storage per labeled conditions, a willingness to sign your quality agreement, B2B healthcare shipping capability and fast consignee reporting for recalls.
Is a 3PL a supplier under FDA's quality system rules?
Usually yes. Under the Quality Management System Regulation, manufacturers must control suppliers whose activities affect product quality, and a 3PL that stores and ships finished devices typically falls into that category.
Should I run a mock recall with a new 3PL?
Yes. A mock recall during onboarding tests how quickly the provider can place stock on hold, produce a consignee report and reconcile quantities, which is the best evidence of real recall readiness.
