The sectors “H502 sea and coastal freight water transport”, “H512 freight air transport and space transport”, “H521 warehousing and storage” and “H532 other postal and courier activities” hold similar figures, from 14 to 32 persons employed there per firm. For sea and coastal freight water transport, as well as freight air transport and space transport, the physical transportation requires very high investments, similar to the rail freight sector. Warehousing and storage firms need at least real estate or storage space to offer services. Other postal and courier activities are often carried by subcontractors with one vehicle. Investments here are very low in comparison.
The transportation via pipeline sector (H495) holds many gaps as not every country has pipeline transportation (“no comp.”) or values are not reported mainly due to confidentiality issues (“confidential”).
