Duties and taxes are charged by Customs in the destination country and the receiver is responsible for paying them.
To make it simpler, DHL will pay the charges on the receiver's behalf and collect payment from the receiver either before or on delivery. Generally, we are unable to deliver parcels until these have been paid.
DHL Express does offer the opportunity for DHL account holders to pay for duties and taxes on behalf of the receiver.
In that case, after shipment delivery, DHL invoices customers for the duties and taxes we paid on their behalf at the destination, plus a small administration fee. This optional service is called Duties and Taxes Paid (DTP).
