In the event of an effective revocation, the services received by both parties shall be returned and any benefits derived (e.g. interest) shall be surrendered. If the CONSUMER cannot return the received performance to HOECHSTMASS Balzer GmbH in whole or in part, or can only return it in a deteriorated condition, the CONSUMER may be required to pay compensation. This does not apply to the surrender of goods if the deterioration of the goods is exclusively due to their inspection - as it would have been possible in a retail store. The CONSUMER does not have to pay compensation for any deterioration caused by the intended use of the goods. Goods that can be sent by parcel are to be returned at the risk of HOECHSTMASS Balzer GmbH. The CONSUMER shall bear the costs of the return shipment if the delivered goods correspond to the ordered goods and if the price of the goods to be returned does not exceed an amount of 40 euros or if, in the case of a higher price of the goods, the CONSUMER has not yet rendered consideration or a contractually agreed partial payment at the time of the revocation. Otherwise, the return shipment is free of charge for the CONSUMER. Items that cannot be sent by parcel post will be collected from the CONSUMER. Obligations to refund payments must be fulfilled within 30 days. The period begins for the CONSUMER with the dispatch of his declaration of revocation or the item, for HOECHSTMASS Balzer GmbH with its receipt.
