A role-and-boundary explainer for US-market buyers and sellers of used medical devices, current as of September 2026. It is general information, not legal advice, and it does not determine your regulatory status ¡ª verify each point against the current FDA guidance and take advice on your own facts.
The question people actually ask is “is it legal to resell used medical devices?” That question cannot be answered as posed, because it has no single answer. The answerable question is narrower and much more useful: what activity am I performing on this device, and what role does that activity create for me? Once the activity is named, the obligations follow ¡ª and so do the questions worth asking a lawyer.
The question behind the question
Used-device transactions cover a wide span of activity. At one end, an entity buys a device and resells it in the condition it received it, sometimes described as selling “as is.” At the other end, an entity repairs, reconditions, updates software, replaces major assemblies or repackages the device before it goes back onto the market. Those two activities sit in different places in the regulatory framework, and the same company can do both without noticing that it has changed roles.
That is why “we only sell used equipment” is not a complete description of a business. The description has to include what happens to the device between purchase and sale.
Device, servicing and remanufacturing
FDA has been working on this boundary for decades. A 1997 proposed rule addressed refurbishers, rebuilders, reconditioners, servicers and “as is” remarketers of medical devices. In 2016, FDA published a series of Federal Register notices and proposed rules on refurbishing, reconditioning, rebuilding, remarketing, remanufacturing and servicing of medical devices performed by third-party entities and by original equipment manufacturers. The current anchor is a final guidance whose availability FDA announced on 10 May 2024, titled “Remanufacturing of Medical Devices.”
That final guidance is the practical place to start, because its stated purpose is to clarify whether activities performed on a device are likely to be “remanufacturing,” to clarify existing regulatory requirements for entities that remanufacture, and to recommend information that should appear in labeling for devices intended to be serviced over their useful life. Read it against what your organization actually does ¡ª not against what its marketing says it does.
| Activity | What it looks like in a used-device business | Why it matters here |
|---|---|---|
| Selling “as is” | Device is bought and resold in the condition received, with no work performed | This is the activity the framework treats most simply, and it depends on the device genuinely not being changed |
| Servicing | Maintenance or repair intended to keep the device performing as labeled | Keeping performance within the labeled specification keeps the entity in a servicing role |
| Reconditioning or rebuilding | Substantial restoration, replacement of major assemblies, or change of performance | Activities that significantly change the device’s performance, safety or intended use can move the entity into a manufacturing-style role |
| Software changes | Reinstalling, upgrading, resetting or modifying device software | Software can change device behavior, so it belongs in the same analysis, not in a separate technical box |
| Repacking or relabelling | New packaging, new labels, new instructions or a new brand name | Packaging and labeling actions carry their own requirements, and they also change how the device is presented to the market |
The line between the middle rows of that table is where most used-device businesses live, and it is a line that has to be drawn from what is done to the device rather than from what the invoice calls it.
Three situations, three role questions
Abstract discussions of roles become useful when they are applied to the situations that actually occur in this market. In each of the three below, one question decides which side of the boundary you are on.
| Situation | The question that decides your role | What to document |
|---|---|---|
| Buy and resell in the condition received | Did anything change between receipt and sale ¡ª including cleaning, repackaging, software state or configuration? | An intake condition record, the sales description, and a written statement of what was and was not done |
| Repair or service before resale | Did the work restore the device to its labeled performance, or change its performance, safety or intended use? | Work performed, parts fitted, software state before and after, and the verification results that followed |
| Import and resell | Which party is the importer of record, and what does that party owe before the device can be placed on the market? | Import documentation, an accurate device description, and the regulatory status of the device in the destination market |
In all three, the deciding fact is a record rather than an intention. A business that can produce an intake condition note, a work record and a description of what was sold is in a position to answer the role question with evidence. A business that cannot is relying on its own memory of what the invoice said.
What a reseller must and must not do
Without substituting for legal advice, three behaviors cause most of the avoidable trouble in this market. The first is describing work in words that do not match it ¡ª calling a rebuild a “refurbishment” or a spec change a “repair.” The second is assuming that the seller’s role automatically transfers with the goods. The third is treating any single published rule as a complete answer for a company whose activities span several rows of the table above.
The practical discipline is to document the condition of each device on intake, document exactly what was done to it, and keep the two records separate. If a device was received in one state and sold in another, the file should say what changed and who changed it. That record is what allows a competent adviser to tell you your role ¡ª and what allows you to show it later.
Labeling obligations
Labeling is where roles become visible to a regulator and to a buyer. A device should carry the labeling the manufacturer provided, and if a company repackages, relabels or alters the instructions, it should treat that action as one that may change its role rather than as a logistical detail. The 2024 final guidance’s labeling recommendations for devices intended to be serviced point in the same direction: the labeling is part of how the device’s continued safe use is communicated.
For buyers, labeling is also a due-diligence item. Confirm that the device you are purchasing carries intact, legible labeling that matches the model and configuration you believe you are buying ¡ª the same discipline that applies in any equipment purchase, with more consequence in a regulated market.
Importing used devices
Importing changes the picture again, because the entity bringing a device into the United States takes on obligations that a purely domestic reseller does not. The details depend on the device and the transaction, and the reliable next step is to identify which party is the importer of record for the shipment and what that party is required to do before the goods arrive.
Two habits reduce import problems. First, describe the device precisely on the customs documentation ¡ª model, condition, and the fact that it is used, where that is the case. Second, resolve the regulatory questions before shipping rather than after, because a device that cannot be entered cannot be sold, and storing it while the question is answered costs money.
Registration and listing roles
Establishment registration and device listing requirements attach to particular roles rather than to the device alone, and the roles that trigger them are not the same as the role of a party that only buys and resells. Because those requirements depend on what the entity does, the analysis begins with the activities documented in the previous sections: if a company’s activities place it in more than one role, it may hold more than one set of obligations.
The efficient way to resolve this is to bring a factual summary to an adviser: a list of the activities you perform, the device types you handle, and the markets you sell into. A role analysis takes minutes with those facts and much longer without them.
When to involve counsel
- Before you begin performing work on devices that will be returned to the market.
- Before repackaging, relabelling or rebranding a device.
- Before importing devices into a market you have not previously supplied.
- When your activities span more than one row of the activity table above.
- When a buyer, hospital or distributor asks you to confirm your regulatory status in writing.
Questions buyers ask
Is reselling used medical devices allowed?
Used-device transactions are part of the market, and the framework addresses them ¡ª but whether a particular transaction is straightforward depends on what is done to the device, not on the word “used.” The activity determines the answer.
When does servicing become remanufacturing?
That is exactly the question the final guidance published in May 2024 exists to clarify. Read it against the work your organization performs; do not infer the answer from the label your business uses.
Does a reseller need FDA registration?
Registration and listing obligations follow particular roles. A business that only buys and resells may not be in the same position as one that also imports, repacks, relabels or changes device performance ¡ª which is why the role analysis should come before the registration question.
Name the activity, document the condition, and keep the two records apart ¡ª that is what makes the regulatory question answerable. If you are buying or selling used devices and need the condition and service records that travel with a unit, ask HHG for the documentation on a specific item, or browse the current listings.
