If you consider freight charges for both air freight and sea freight, no doubt the former appears much more expensive. However, one needs to consider that charges apply differently for both modes of transport.
While air freight charges go by weight, sea freight also adds the dimension of volume and container. So, going for sea freight makes cost-effective sense when applied to larger and heavier shipments that would otherwise not fit air transport.
Also to be considered are differences in warehousing fees, with seaports significantly costlier than at most airports.
What are the types of road transport?
The type of road transportation a company chooses depends on the type of cargo- (dry, liquid, gaseous, perishable, high value, hazardous, palletized or oversized and so on).
Trucks and semi-trailers like 53-foot dry vans, flatbeds, and reefers all carry particular goods.
Two types of road transport
- Non-motorized transport (walking, cycling and use of domestic animals)
- Motorized transport (all type of engine-enabled transportation modes- like semi-trailers and heavy haul trucks),
What are the types of cargo?
Cargo can fall into five key types, with the specific type of cargo determining the best mode of transportation.
The four types of cargo are:
Dry bulk cargo refers to all items shipped dry and in large quantities. They include cereals/grain, iron ore, and coal among others.
This type of cargo includes items transported in bulk but in parts that can easily break (breakbulk!). Examples are wood products, cocoa, steel rolls.
‘Roll-on / roll-off’ (ro-ro) cargo go in ferries and other vessels – on at a point and off at the destination. The ro-ro cargo includes cars, buses, and trailer trucks.
Such cargo includes crude oil, petroleum, vegetable oils and other items transported in liquid form. Liquid cargo is moved using tankers or pipelines.
