Any shipments outside of the European Union will be subject to possible customs taxes and duties. These are always borne by the recipient. They will need to pay the amount requested by the customs authorities in order to have the goods released.
It is important to remember that DPD has no influence over customs processes, the restrictions applied or the costs of customs duties. Each country has their own legislation and for this reason we advise you to look up the regulations concerning importing/exporting for the country in question before making your shipment.
