About transportation and foreign trade

Cost of road transport
Road transport is more flexible than the other three modes. It is relatively easier to track your goods, secure consignments, schedule the transport and pay the relevant fees. On the other hand, long distances are not time-efficient especially if traffic is involved. Some countries may have high toll fee charges and the possibility of getting your goods damaged is high as well.
Where it comes to large quantities, road transportation costs around 3 to 7 US dollarcents per ton per kilometer. If you want to own your own trucks, the costs of having such a truck may be around 1300 to 1900 USD per day, excluding driver. If you just want to send a package of 50 kg over a distance of 300 km then in the US that may cost around 200 USD.
Cost of sea container transport
Transport by sea allows you to ship large volumes with lesser cost than the other three modes. Shipping containers could also be used when transporting goods by land. However, international transportation could be delayed due to the slow pace, weather shifts and inflexible routes and schedules. Typical rates for transport by sea container are:

Route	20 ft container	40 ft container
USA-Canada	600-800 USD	900-1100 USD
USA-China	1600-1800 USD	2400-2700 USD
UK-Spain	700-900 USD	1100-1300 USD
UK-Australia	2500-2800 USD	4000-4500 USD

Please note that these are the costs from port to port. There may be additional costs for land transportation. Rates for destinations with civil wars may also be much higher.
