Buying Remanufactured Parts: Process, Core Charges and Exchange Terms

Remanufactured, or reman, parts can offer another route when replacing a major machinery component. The purchase needs two checks: the process behind the finished product, and the commercial terms attached to any return of your old component.

A reman description should identify the organisation that carried out the work and the specification it applied. An exchange price should explain how the core deposit or credit works. Neither should be left for the buyer to infer.

What does remanufactured mean in an offer?

Ask the supplier for a documented process covering disassembly, cleaning, inspection, restoration or replacement, reassembly and testing against a stated specification.

Manufacturer programmes provide useful examples. Caterpillar describes its Cat Reman process as reclaiming used components and returning finished products to the OEM performance specifications of new Cat products. Komatsu states that its remanufactured components use its original equipment specifications, assembly processes and test procedures.

These are descriptions of those manufacturers' programmes. A separate seller's “reman” listing needs its own supporting evidence. Remanufactured does not automatically mean remanufactured by the original machine manufacturer.

Identify the programme and the actual component

Before comparing prices, request:

  • The remanufacturer's name and any programme or product reference.
  • The offered part number and confirmation of compatibility with your machine serial number.
  • An identification plate, serial number or other traceable unit reference.
  • The specification used and available process or inspection documentation.
  • Final test evidence, or programme testing information where individual results are not supplied.
  • The date completed, storage arrangements and commissioning requirements.
  • The warranty provider and full terms applicable to that item.

Ask whether the unit is complete for your application. Establish which ancillaries, controls or installation items you must transfer or purchase separately.

Understand the core exchange

The core is the old component returned for assessment and potential reuse in remanufacturing. An exchange offer may require a refundable deposit or make a credit conditional on returning an acceptable core. Other offers may be outright sales.

Obtain the actual terms for your quotation. Caterpillar, for example, makes clear in its Cat Reman information that advertised savings depend on core return and that core conditions apply. That does not establish the terms of a different remanufacturer or seller.

Ask these questions before placing the order:

  1. What is payable initially, and what amount could be refunded or credited?
  2. Which old part numbers or configurations are acceptable?
  3. What completeness and damage conditions apply?
  4. When does the return deadline start?
  5. Who arranges and pays for return packing and transport?
  6. Who assesses the core, and how are deductions documented?
  7. When will the credit be issued, and how can an assessment be queried?

If your old component is cracked, dismantled or missing parts, disclose that when requesting the quotation. Ask whether photographs can support an initial assessment, while recognising that final acceptance may require physical inspection.

Compare cash required with the eventual cost

A refundable deposit still affects the amount you must fund initially. Keep that separate from the anticipated cost after an accepted core return.

For illustration only, suppose a component costs £8,000, the refundable core deposit is £2,000 and agreed return freight is £400. Initial payment for the component and deposit would be £10,000. After a full £2,000 refund, the component plus core-return freight would cost £8,400. Forward freight, taxes and installation are excluded from this example.

If the core is rejected, or only partially credited, the result changes. Use the seller's actual figures and acceptance terms before deciding whether an exchange offer fits your budget.

Plan the return before the replacement arrives

Check whether you can retain the old component until the replacement is installed and working, and whether that fits the deadline. Ask about draining, capping, preservation, suitable packaging and any documentation the seller requires.

Agree who handles return transport. Confirm any cross-border requirements with the seller and your freight provider for the actual route, rather than assuming that the outward and return shipments will be identical.

An enquiry for an exchange component

Please quote reman [component/reference] for [make/model], serial [number]. Identify the remanufacturer and specification. Show the outright or exchange price, core deposit, acceptance conditions, return deadline and freight separately. Our available core is [condition]. Please include testing information, warranty terms and dispatch timing.

Common buyer questions

Is a reman part the same as a rebuilt part?

Do not treat the labels as interchangeable. Compare the stated process, specification and supporting records.

Does every reman purchase need a core?

Ask whether the offer is exchange or outright. The word reman alone does not establish the commercial arrangement.

Does reman always include a manufacturer warranty?

Check who made the product and who provides the cover. Request terms for the exact item and application.
