Sea freight is the transport of goods, mostly grouped into containers, via Rotterdam, or another port, to other ports around the world. The carriage of goods by sea is in ratio of speed, volume and price very conveniently and economically.
The transport by truck is still one of the most important ways to transport goods. Regardless of the choice for the transport with other means of transport, e.g. sea freight or air freight, road transport still makes part of the logistics chain.
Under special transport, also called exceptional transport, fall goods that by their measurements not in a regular trailer or container can be transported. These must then be transported in a different way, with e.g. a (semi-) lowbed-trailer or open top container.
