A core charge is a down payment you'll make prior to the manufacturer receiving your used component. You must pay the core price if you don't already have the core at the time of purchasing. Some producers will rebuild or refurbish the component you send back for their upcoming client. Once you return the core, you will receive a refund for the core payment.
