01What we do

The link between the market and remanufacturing

No cores, no reman. We make sure the right used parts reach the remanufacturer in the right quality at the right time.

All services

  • Sourcing & return flow

    Worldwide purchasing of OEM used parts through an established network of workshops, parts dealers, wholesalers and recycling companies.

  • Identification & inspection

    Every core is positively identified, checked for completeness and remanufacturability, and stored by type.

  • Supply ex stock

    Demand-driven supply to remanufacturers in Europe and worldwide, with the logistical advantages of the Rhine-Ruhr region.

02How we work

From offer to payment in three steps

Whether you sell cores or source them: the process is short and you always know where you stand.

  1. Offer

    You send part number, quantity and a photo. We evaluate per line and usually reply within one working day.

  2. Collection or delivery

    From pallet quantity our carrier collects, smaller quantities ship by parcel. Remanufacturers receive type-sorted deliveries aligned with their production cycle.

  3. Inspection and payment

    Every core is identified and inspected in Hilden. Suppliers get feedback per line and payment after receipt of goods.

04Sustainability

Remanufacturing is the circular economy in practice

A remanufactured part retains most of its material and the energy already invested in it. That conserves resources, cuts emissions and keeps OE-quality vehicle parts affordable.

For us, remanufacturing used parts is not simply a business. Our philosophy is driven by sustainability and continuous improvement. We see remanufacturing as an important element in preserving the environment and keeping mobility affordable.

  • 60–80%of the new-part price: typical market price of a reman part (European Remanufacturing Network)
  • Housings, shafts and castings stay in the product, only wear parts are new
  • Less energy and fewer emissions than casting and forging new parts
  • No new raw materials for the main bodies

“No cores, no reman.”

07FAQ

Frequently asked questions about cores and core brokers

Knowledge

What is a core?

A core is a used original part (OEM used part) that serves as the basis for industrial remanufacturing. After remanufacturing the part once again meets original-equipment quality and is sold as an exchange part.

What does a core broker do?

A core broker sources used parts on the market, identifies and inspects them, stores them by type and supplies them to remanufacturers as needed. STP-Parts thereby provides the security of supply that remanufacturers need for their production.

Which parts does STP-Parts buy?

Primarily steering gears, steering boxes, hydraulic and electric power steering pumps, starters, alternators, brake calipers, clutches and turbochargers from passenger cars, trucks and commercial vehicles. Other parts on request.

What condition must used parts be in?

Complete, not opened and without severe housing damage. Normal signs of use are no problem. For an assessment, the part number, quantity and a few photos are usually sufficient.

Does STP-Parts deliver internationally?

Yes. We are globally organised and supply remanufacturers in Europe and worldwide. Our main warehouse is located in Hilden near Düsseldorf, Germany.
