Many of the requirements to ship heavy machinery to Europe are the same as with transporting a car or small truck. There are several registration and customs items to be covered no matter the size of the cargo. In every case, the equipment owner should be sure to have up-to-date registration and insurance information, with original documents available for inspection when a customs agent or shipping official asks to see them.
It is generally less expensive to transport motorized vehicles with roll on/roll off service, so this may also be practical when you need to ship heavy machinery to Europe. If the machinery can be driven onto the ship and secured on an inner deck, this could save a considerable amount of money over container or flat rack shipping, for example. These are questions that can be answered by shipping and transport agents who make all the arrangements for you, as well as by the shipping company itself.
