Who pays the customs duties (import/export/exchange)?

Generally, customs duties are always to be paid by the buyer. It makes no difference whether import or export. However, if you request an exchange from us, you have the option of returning the item to be exchanged to us free of custom charges: The consignment must be handed over with a completed customs declaration of contents (CN23) and a copy of the original invoice or a return note as proof of the returned goods status. The required customs documents must always be securely attached outside of the package in an appropriate shipping bag. If the customs-relevant documents are missing, this may result in a cost-intensive forwarding to the inland customs office, as the consignment cannot be handled under customs law within the standard process.
