The blockage surcharge means for the customer an increase in the price for the dispatch of goods, the so-called bulky goods shipment. The bulk transport is always associated with an additional effort for the parcel services. The workflows are designed to ship parcels of prescribed sizes and oversized shipments cannot take the normal shipping route on the parcel conveyors. The shipping of bulk goods, therefore, takes place manually by the staff and means more effort with which the Bulk surcharge is mostly justified. Also, you can not use the maximum transport space, because space is designed for the given package sizes.
