IT hardware & components buyback glossary

A plain-English glossary of the IT-hardware and electronic-components buyback terms you'll meet when selling surplus equipment — from EOL and NIST SP 800-88 to MPN, MSL, NCNR and chain of custody. Clear definitions so you know exactly what a buyback desk is asking for and why it affects your offer.

A plain-English glossary of the IT-hardware and electronic-components buyback terms you'll meet when selling surplus equipment — from EOL and NIST SP 800-88 to MPN, MSL, NCNR and chain of custody. Clear definitions so you know exactly what a buyback desk is asking for and why it affects your offer.

EOL — end-of-life

The point at which a manufacturer stops producing or selling a product. EOL hardware is no longer made new, but is not worthless — installed-base demand keeps many EOL servers, storage and networking liquid on the secondary market.

EOS / EOSL — end-of-service-life

End-of-support or end-of-service-life: the manufacturer no longer provides updates, patches or support contracts. A model is often EOL for a while before it reaches EOS, and keeps real resale and parts value well beyond both.

NIST SP 800-88

The U.S. federal guideline for media sanitization. It defines three levels — Clear (logical overwrite), Purge (cryptographic erase or firmware sanitize) and Destroy (physical destruction). We sanitize every data-bearing device to NIST SP 800-88 before resale; we reference it as a methodology, not a held certification.

Data sanitization vs destruction

Sanitization renders data unrecoverable while keeping the device reusable (overwrite or cryptographic erase); destruction physically ruins the media (shred, degauss). Sanitization preserves resale value; destruction is used when a device is non-functional or the seller requires it.

ITAD — IT asset disposition

The managed, certified, compliance-reported retirement of IT assets. A bulk buyback trading desk overlaps ITAD only on data erasure; if you need a fully audited ITAD programme with formal reporting, that is a different service.

Buyback vs trade-in

Buyback is an outright cash purchase of your hardware at its resale value; trade-in credits the value against a new purchase. We buy outright and take title — no purchase required from you.

Bulk / wholesale lot

A quantity of hardware or components sold together to a single buyer — racks, pallets, reels or fleets — rather than unit by unit. Bulk lots are how a trading desk buys; single consumer units are out of scope.

Take title

To buy outright and assume ownership and resale risk, rather than selling on consignment. Because we take title, you get one clean transaction and the gear gone, not a slow pay-as-it-sells arrangement.

Residual value / value retention

The share of original value an asset still holds on the secondary market. It tracks generation, configuration, condition and live demand more than calendar age — see our resale value indexes for the patterns.

RDIMM vs LRDIMM

Registered and load-reduced server memory. LRDIMM buffers the data lines to support higher capacities and DIMM counts; the type and total capacity both affect a server's resale value, so list them.

DIMM population

How many memory slots are filled. A fully populated board carries meaningfully more value than a sparsely populated one — and in 2026 server DRAM is appreciating, so populated memory is worth flagging.

iDRAC / iLO

Dell's iDRAC and HPE's iLO are out-of-band server management controllers. Enterprise licensing (iDRAC Enterprise, iLO Advanced) adds value; keep it intact where possible and note it on your list.

Firmware / activation lock

A configuration or vendor lock that ties hardware to an account or licence. Cleared, unencumbered units sell better; locked devices need the lock resolved and are priced accordingly.

SXM vs PCIe (GPUs)

Two form factors for data-centre GPUs. SXM modules mount on a baseboard (HGX/DGX) and carry more secondary demand than air-cooled PCIe cards; matched node-level sets price best.

HGX / DGX

NVIDIA's multi-GPU platforms — HGX is the baseboard integrators build on; DGX is NVIDIA's complete system. Selling complete nodes or matched sets earns stronger per-unit pricing than loose modules.

MPN — manufacturer part number

The exact, full part number including its suffix. For components it is the single most important field — a part number without its suffix can't be quoted; with it, the desk can price the line.

Date code

A code marking when a component was made. Parts older than roughly two years may need solderability testing; don't mix date codes in one reel unless labelled, as it affects value and handling.

MSL — moisture sensitivity level

A rating (1–6) for how a component reacts to ambient moisture. MSL 2–6 parts live in vacuum-sealed moisture-barrier bags; an opened bag is "expired" until baked, so don't open sealed reels just to photograph them.

Reel / tape / tray / tube

Standard component packaging for automated assembly. Sealed full reels and trays hold more value than partial ("cut tape") or loose stock, because pick-and-place lines need intact, consistent packaging.

CoC — certificate of conformance

Documentation attesting a part's origin and authenticity. Original invoices and a CoC command a "paperwork premium" and move parts faster, because traceable stock is easier to trust than grey-market material.

NCNR — non-cancellable / non-returnable

Order terms under which parts can't be cancelled or returned, common on customised or allocated components. When the authorized channel is closed to returns, the secondary market is the only recovery path for NCNR excess.

Chain of custody

The documented handling of assets from pickup through processing and resale. A clear chain of custody, with NIST SP 800-88 sanitization on every drive, is what lets a seller release data-bearing hardware with confidence.

Decommission

Taking IT infrastructure out of service — from a single rack to a full data hall. Most decommissioned enterprise gear still has real resale value, so it is worth getting a buyback figure before recycling.

For-parts / as-is

Hardware sold without a working guarantee. For-parts and untested units still carry component value and are best bundled into a bulk lot rather than scrapped separately; we buy working and for-parts together.

FAQ

Questions sellers ask

What does end-of-life (EOL) mean for resale?

EOL means the manufacturer no longer makes the product — not that it's worthless. Installed-base demand keeps many EOL servers, storage and networking liquid; end-of-support (EOS) affects value more, but well-configured units still sell in bulk.

What is NIST SP 800-88?

The U.S. federal media-sanitization guideline, defining Clear, Purge and Destroy levels. We sanitize every data-bearing device to NIST SP 800-88 before resale — referenced as a methodology, not a certification we claim to hold.

Why do components need a full part number (MPN)?

Component value swings on the exact manufacturer part number, date code and packaging. A full MPN makes a line quotable; without it, a desk can't price the part.
