Why device 3PL transitions go wrong
Most failed medical device 3PL transitions fail on data, not trucks. The pallets arrive fine, but lot and serial history stays behind in the old system, open holds get released by accident, and a hospital EDI connection goes quiet for a week because nobody re-tested it.
Treat the switch as three parallel moves: the physical inventory, the records that prove where every unit has been, and the commitments you have made to customers and regulators. If any one of the three lags, you end up with product you cannot sell, ship or trace. A good plan names an owner for each move and a single cutover date that all three converge on.
Qualify the new provider before you announce anything
Under a supplier controls approach, a 3PL that stores and ships finished devices is a supplier you must evaluate and approve before use. That means a documented assessment, a signed quality agreement and an approved-supplier record in your quality system before the first pallet moves.
Use the qualification to confirm the basics you are relying on: lot, serial and expiry capture at receiving, FEFO allocation, system-enforced holds, temperature monitoring where your labeling requires it, and complaint and return routing. If the new provider will perform any activity that requires FDA establishment registration, such as relabeling or kitting under your label, confirm that registration status before go-live, not after.
Build the data migration file
Your migration file is the single most important artifact in the project. At minimum, it should include, per unit or per lot:
- Item number, GTIN or device identifier and unit of measure
- Lot or batch, serial number where applicable, and expiration date
- Current status: available, on hold, quarantined, damaged or expired
- Open hold reasons and who can release them
Agree on formats up front. Expiry dates written as month-year in one system and full dates in another will silently break FEFO. Request a full transaction history export from the outgoing provider as well, because your recall obligations do not reset when you change warehouses. Archive it in your own records, not theirs.
Plan the physical move
Move inventory in controlled waves rather than one giant transfer. Many brands start with slow movers and long-dated stock, then move fast movers last so the outgoing site can keep shipping until cutover.
Every wave should ship with a packing list by lot and serial, travel under labeled storage conditions, and be received at the new site with full scanning, not a pallet count. Product requiring refrigeration needs qualified packaging or a temperature-controlled carrier and a data logger record for the transit. Anything that arrives with damage, an unreadable label or a temperature excursion goes to quarantine pending your disposition, exactly as it would on a normal inbound.
Reconnect every channel
Inventory that cannot receive orders is just expensive storage. List every order source and integration before the cutover date:
- Storefront and marketplace connections, including Amazon FBA prep flows
- EDI trading partners for hospitals, health systems and distributors, including 850, 856 and 810 transactions
- Your ERP or order management system, plus any customer-specific packing list or label rules
- Carrier accounts, LTL routing guides and dock appointment requirements
Each hospital or distributor trading partner may require its own testing cycle. Start those conversations early and ask whether they need advance notice of a new ship-from address.
Run a reconciliation before go-live
Before the old site stops shipping, reconcile the new site's on-hand inventory against the migration file and your ERP at the lot and serial level. Differences should be explained, documented and closed, not netted out.
Then run a mini mock recall at the new site: pick a lot that has moved and ask for a report of where it sits and what status it is in. If the new provider cannot answer quickly on day one, you have found the problem while it is still cheap to fix.
After cutover: the first 90 days
The first quarter at a new provider is when small process gaps surface. Hold weekly reviews of order accuracy issues, receiving discrepancies, short-dated shipments and any deviation reports. Close the loop on each one through the quality agreement process rather than email.
Plan a formal supplier review at roughly the 90-day mark. Confirm that complaint and return routing works as written, that quarantine releases are documented, and that the records you would need for a recall or audit are complete and retrievable.
Communicate with customers without alarming them
Customers mostly need to know three things: whether anything about their orders will change, when the ship-from address changes, and who to contact if something looks different. Hospitals and distributors may need an updated vendor or ship-from record, new dock contacts and confirmation that labels and ASNs will keep the same format.
Send that notice a few weeks before cutover, then again on the day itself. For DTC customers, there is usually nothing to announce, but watch for subscription orders scheduled around the cutover window. Pause or reroute them deliberately so no recurring order lands in a warehouse that has stopped shipping or one that is not ready to start.
Finally, agree on a short shipping blackout or reduced-volume window with both providers. A day or two of lower volume during the final wave is far easier to explain than a week of mis-picks caused by inventory that is physically in one building and systemically in another.
Frequently asked questions
How long does it take to switch medical device 3PLs?
A typical switch takes several weeks to a few months, depending on SKU count, the number of EDI trading partners to re-test, temperature-controlled inventory and how quickly the new provider can be qualified under your quality system.
Do I need to tell the FDA when I change 3PLs?
It depends on what the 3PL does. Storage and distribution of finished devices alone generally does not trigger new registration obligations, but if the provider performs activities like relabeling or repackaging, registration and listing information may need to change. Confirm with your regulatory team.
What records should I get from my old 3PL?
Get a full export of lot, serial and expiration data for on-hand stock, plus the complete shipment history by consignee, receiving records, hold and quarantine logs, and temperature records. You need that history to support recalls and audits after you leave.
