A due-diligence guide for buyers sourcing used medical equipment from dealers, brokers and marketplaces, current as of September 2026. It is not legal advice and cannot guarantee that any transaction is free of risk.
When you buy used equipment from a seller you have not dealt with before, you are buying two things at once: the equipment, and the seller’s ability to stand behind it. The second is harder to inspect, and it is the one that determines what happens when the crate arrives with the wrong model inside. Vetting is simply the process of turning that second question into evidence you can review before money moves.
What you are actually buying: trust or equipment
A used-equipment transaction combines a product purchase with a service relationship. Even a clean sale involves questions after delivery ¡ª a missing accessory, a documentation gap, a unit that behaves differently from its description. The seller’s ability to answer those questions depends on whether they hold the goods, know the device and remain contactable.
That is why vetting starts before the technical questions. A seller who is easy to verify as a business and difficult to verify as an equipment holder is a different risk from one who is the reverse, and the two cases call for different contract terms.
Verifying business identity
Identity checks are the cheapest part of due diligence and the most frequently skipped. The aim is to establish that the entity you are paying exists, is registered where it claims to be, and can be held to a contract.
- Match the trading name, the registered entity name, the bank account name and the name on the invoice. Mismatches between them are the most common early warning sign.
- Check the registration number against the public company register for the stated jurisdiction.
- Confirm the address resolves to a real operating location, and ask for a live video walkthrough if the value justifies it.
- Confirm that the person negotiating has authority to sell on behalf of that entity.
- Check that contact details ¡ª domain, email, phone ¡ª belong to the entity rather than to a disposable account.
Evidence of inventory and competence
Holding inventory and understanding it are different capabilities, and both matter. The seller should be able to show the specific unit, not a stock photograph, and to answer technical questions about it without consulting someone else.
| Check | What good looks like | What to treat as a warning |
|---|---|---|
| Unit identification | Serialized photographs of the exact unit, including labels and any defects, taken when you ask | Reused catalogue images, or images that clearly show different units |
| Inventory control | A stock list that matches what you are offered, with locations and quantities | Vague availability, or an offer that depends on “sourcing it” after you pay |
| Technical knowledge | Direct answers about configuration, accessories, documentation and known issues | Answers that only quote the listing back to you |
| Condition disclosure | Volunteered defects and their location, with photographs | Defects discovered only after you ask specifically |
Document and reference checks
Ask for the document pack before negotiating price, not after: service records, test or performance evidence where applicable, and the paperwork that identifies the unit. A seller who keeps these records routinely produces them quickly; a seller who does not will produce something partial.
References are worth the phone call. Ask two or three previous buyers the same three questions: did the goods match the description, did the seller respond when something needed fixing, and would they buy again. A reference that cannot describe an actual transaction is not a reference.
Payment and contract posture
The payment terms tell you how the seller expects risk to sit. Large advance payments to a newly verified entity, requests to pay a third party, or resistance to writing terms into the order all shift risk towards you. Where the value is significant, an escrow or staged payment arrangement aligned to inspection is the usual way to keep risk balanced between the parties ¡ª the mechanism matters more than the name it is given.
In the contract, confirm the basics: exact model and serial, what is included, the condition representation, the inspection window after delivery, what happens if inspection fails, and which law and forum govern a dispute.
Red flags checklist
- Name mismatches across invoice, bank account and registration.
- Urgency to close before documents can be produced.
- Payment requested outside the documented contract route.
- Unit photographs that cannot be reconciled into one physical device.
- Reluctance to state the serial number before payment.
- Terms that exclude inspection or remove return rights entirely.
- Price materially below comparable units with no explanation of condition.
Building the scorecard
Turn the checks into a scorecard and apply the same one to every seller: identity verified, inventory evidenced, documents available, references reachable, payment terms balanced, contract terms clear. Score each item as confirmed, partial or unverified, and let the pattern ¡ª rather than any single item ¡ª drive the decision. A single unverified item can be resolved with a contract term; a seller who is unverified across several categories is not a documentation problem.
Questions buyers ask
Is a registered company automatically a safe seller?
No. Registration establishes that the entity exists and can be contracted with; it says nothing about inventory, competence or how a dispute will be handled. Registration is the first checkpoint, not the conclusion.
Should I always use escrow?
The mechanism should match the value and the risk. Staged payment tied to inspection achieves a similar effect; the essential point is that the seller’s payment and your inspection are linked rather than sequential.
What if a seller cannot provide service records?
Treat the equipment as unverified for that aspect and price the consequence: an inspection on arrival, a service check before clinical use, or a condition of acceptance written into the order.
Vet the seller with the same discipline you apply to the equipment, and put the findings in the purchase file. If you want a second opinion on a transaction you are evaluating, send HHG the listing and the seller’s documents ¡ª the team can tell you which items still need evidence.
