What steps to follow if the exports which are not accepted by the buyer are not returned physically?

There is an export company selling mines. During the delivery, some goods were not accepted by the receiver but they also can not be returned. What kind of a document the receiver can draft to reduce its debt to us, which would also reduce our receivables?

There is nothing to do for the goods that are not returned. There should be a legal transaction for the export price.
