How the deposit works
When buying an exchange part, the buyer pays a deposit on top of the part price. If he returns the removed used part within the deadline, the deposit is credited. This is how the remanufacturer secures his supply of cores. Deposits range from a few euros for starters to several hundred euros for EPS steering gears and turbochargers.
Why deposits are refused
- The used part does not match the exchange number supplied (different variant)
- The part is incomplete or opened
- Housing damage or transport damage
- Deadline exceeded, 30 to 90 days depending on the programme
- Wrong packaging; some programmes require the original box
Every programme has its own conditions. What one manufacturer accepts, the next one refuses.
What happens to parts that fit nowhere
Used parts from repairs with new parts, parts of other makes, parts past the deadline and parts whose deposit programme has ended are left at the workshop or the dealer. For these parts there is the core broker: we buy independently of deposit schemes and bring the parts to the remanufacturer who needs them.
Deposit or sale: which pays off?
| Situation | Recommendation |
|---|---|
| Exchange part bought, used part matches the number | Deposit return to the supplier |
| Exchange part bought, used part is a different variant | Sale to core broker |
| New part fitted, used part left over | Sale to core broker |
| Deadline passed | Sale to core broker |
| Lot of mixed returns in the trade | Sale to core broker |
Frequently asked questions
Can I sell deposit parts to STP-Parts instead of returning them?
You can, but the deposit is usually higher than the core price. Return the matching parts and sell us the rest.
Do you also buy parts for which the supplier refused the deposit?
Yes. The refusal relates to that supplier's programme. As a core, the part may still fit another remanufacturer.
