A vocabulary guide for buyers, sellers and biomedical teams trading used medical devices, current as of September 2026. It is general information, not legal advice, and it does not decide how any particular activity should be classified.
Three words get used interchangeably in used-equipment listings, and they do not mean the same thing: repair, refurbishing and remanufacturing. The difference is not linguistic. It decides who carries the obligations that come with a device, what the buyer can reasonably expect, and what the seller’s own paperwork has to be able to show. This page sets out the vocabulary and the evidence that reveals which activity actually took place.
Why the label matters
Most disputes about used equipment are not about whether the device works. They are about what was promised and what was done. A listing that says “fully refurbished” without saying what was replaced tells the buyer nothing verifiable, while a work record that lists the components replaced and the verification performed after the work tells them almost everything.
Regulators have approached the same question because the answer changes the obligations of the entity doing the work. In the United States, FDA addressed refurbishing, reconditioning, rebuilding, remarketing, remanufacturing and servicing as far back as a 1997 proposed rule, returned to the topic with a series of notices and proposed rules in 2016, and published a final guidance whose availability was announced on 10 May 2024 under the title “Remanufacturing of Medical Devices”. That guidance is intended to clarify whether activities performed on a device are likely to be remanufacturing, to clarify existing requirements for entities that remanufacture, and to recommend information that should appear in labeling for devices intended to be serviced. In the European Union, obligations attach under Regulation (EU) 2017/745 to the person who places a device on the market under their own name and to those who modify a device in a way that affects its compliance; the regulation’s text is the authority, and the specific provisions should be read there.
Repair
A repair restores a device that has failed, or is about to fail, to the performance it was designed to deliver. The device keeps its identity, its intended purpose and its labeling. Repair is the narrowest of the three activities, and it is the one most easily evidenced: a work order naming the fault, the part replaced and the verification performed afterwards describes a repair completely.
Refurbishing
Refurbishing is a commercial description more than a regulatory one. It generally covers cleaning, cosmetic restoration, replacement of worn components, and sometimes software updates, with the device returned to sale as a working unit of the same type. The ambiguity sits in how far the work went: replacing a worn seal is clearly refurbishing, while replacing core assemblies and changing configuration begins to look like something else.
That ambiguity is why an exact list of work performed is the only useful evidence. “Refurbished” is a conclusion; the work record is the fact.
| Term | What it implies | Evidence that supports it |
|---|---|---|
| Repair | Restores failed performance; identity, purpose and labeling unchanged | Work order with fault, part and post-repair verification |
| Refurbishing | Commercial restoration: cleaning, cosmetics, worn-part replacement, sometimes software update | Itemised work list, parts used, and verification against the manufacturer’s specification |
| Remanufacturing | Work that changes the device’s performance, safety or intended use enough that the entity may take on manufacturer-style obligations | Documented change of specification or configuration, with the regulatory analysis that followed it |
Remanufacturing
Remanufacturing describes activity substantial enough that the resulting device can no longer be treated simply as the original manufacturer’s product. The practical test that the 2024 FDA guidance is designed to help with is whether the work is likely to be remanufacturing: significant changes to performance, safety or intended use are the kind of thing that moves an entity into a different regulatory position.
Two consequences follow for anyone trading used equipment. First, the entity doing the work needs to know which side of the line it is on, because the obligations differ. Second, a buyer receiving a device that has been through substantial work needs the documentation that goes with it, not just an assurance that it was “done properly”.
Regulatory consequences by region
The vocabulary is not harmonised across markets, so the same activity can carry different obligations depending on where the device is placed on the market. In the United States, the starting point is the 2024 final guidance on remanufacturing, read together with the servicing context described above. In the European Union, the starting point is Regulation (EU) 2017/745 and the question of who places the device on the market and whether the work affects compliance.
Neither framework can be summarised accurately in a sentence, and the correct application depends on facts about a specific device and a specific activity. What can be said generally is that the more substantial the work, and the more it changes what the device is or does, the more likely it is to move the entity performing it into a different role ¡ª and the more important it becomes to obtain advice on the specific situation.
Evidence that shows what actually happened
Buyers cannot verify a word, but they can verify a record. Ask for these and compare them against one another:
- A work record listing each action performed, with dates and the person or organization responsible.
- Parts documentation: what was replaced, and whether the parts were the manufacturer’s or third-party.
- Verification evidence: the test or inspection performed after the work, with results.
- Software and configuration state, before and after.
- Labeling and instructions as supplied with the device, and whether they match the original manufacturer’s labeling.
Where those records disagree ¡ª a work list that mentions a part the verification record does not cover, or labeling that does not match the device’s configuration ¡ª the disagreement is the finding to resolve before purchase.
Questions buyers ask
Does “refurbished” have a legal definition?
Not one that applies uniformly across markets and device types. It is primarily a commercial description, which is exactly why the work record matters more than the word on the listing.
How do I know whether work crossed into remanufacturing?
By looking at what changed: performance, safety or intended use. That is the question FDA’s 2024 final guidance addresses. If the answer is unclear from the records, that is a reason to obtain advice before buying or selling.
Do the same words mean the same thing in every country?
No. The frameworks and their vocabulary differ, so a device described as refurbished in one market may sit differently in another. Check the rules that apply where the device will be placed on the market.
Use the words carefully in your own listings and documents, and read them carefully in someone else’s. If you are buying or selling a device and need to know what work was performed, ask HHG for the work and verification records, or browse the current listings.
