The parcel services usually have a predetermined maximum size for parcel shipments. The package classes are defined differently in terms of permissible weight and size to ensure easy handling of the packages. But sending big packages is not a problem. The bulky goods shipment is possible with almost all service providers. If the shipments exceed the maximum size, they are considered bulky goods and will be handled with other shipping terms. The sorting system can not process these packages, so they are sorted by hand. The vehicles are also adapted to the predefined package classes in order to achieve optimal use of the storage space. The bulky goods transport but usually has unusually large dimensions and due to the expense is required for many companies a surcharge for bulk shipping.
