These words get used as if they mean the same thing. They don't. Only one of them, remanufacturing, has a formal definition in FDA regulation. "Refurbished" and "re-certified" are market terms, and each seller decides what they cover. So the label alone won't tell you what was done to a device, but it does tell you which questions to ask.
Servicing and remanufacturing: the line FDA draws
FDA describes servicing as the repair or preventive and routine maintenance of parts in a finished device. The aim is to return the device to the original manufacturer's specifications.
Remanufacturing is any processing, conditioning, renovating, repackaging, restoring or similar act that significantly changes a finished device's performance or safety specifications, or its intended use. FDA's servicing and remanufacturing page sets out both definitions and links to its 2024 guidance on telling them apart.
The distinction turns on the result, not the name of the activity. Replacing a worn part with an equivalent one to restore original performance is generally servicing. Changing what the device can do, or how safely it does it, moves toward remanufacturing, and a remanufacturer takes on manufacturer-level regulatory obligations. That's why a company's own description of its work doesn't settle the question.
The market terms
| Term | What it usually means | What to ask |
|---|---|---|
| Used | Previously owned. May be sold as found, with little or no testing. | Has it been tested at all? Is it sold as-is? |
| Refurbished | Cleaned, repaired and tested, to a standard set by the seller. | What was tested and replaced? Is there a written record? |
| Re-certified | Tested and documented as meeting a stated specification, usually with a certificate. | Certified by whom, against what specification? |
| Remanufactured | Changed significantly enough to meet the FDA definition above. | Who is the legal manufacturer now? What is its FDA status? |
| New | Unused, sold with the original manufacturer's warranty. | Is the warranty transferable through this seller? |
What "re-certified" means at Precision MedLab
When we call a unit re-certified, we mean it was inspected, repaired where needed, calibrated and biomed-tested to manufacturer specification, and that it ships with a certificate of conformance. That certificate also lists what our warranty covers on that unit. Our process page walks through the steps.
Five questions that cut through the label
- What specification was the unit restored to, and does it match the original manufacturer's?
- Which parts were replaced, and were they OEM or equivalent?
- Was any software, hardware or labeling changed?
- What test results can you give me for this serial number?
- Who stands behind the unit if it fails, and for how long?
A seller who does this work properly can answer all five without hesitation. Vague answers are useful information too.
