Container Shipping


Container Shipping

Shipping containers via rail freight.

Sizes of Containers

Container shipping uses standard sized containers of 20 foot (6.09 meters), 40 foot (12.18 meters), 45 foot (14.6 meters) and 53 foot (16.15 meters). TEU is twenty-foot equivalent unit, which is the standard measure. Containers are built to international standard making them interchangeable between shipping companies, rail and truck companies.

The different types of containers include open end, open side, open top, half height, flat rack, refrigerated, liquid build (tank), modular and standard dry cargo.


Container shipping began in its current form in 1956. In 1961, the International Organization for Standardization set standard sizes for all containers. Prior to standardized container shipping, a manufacturer packed their goods onto a ship. Those goods were then unpacked from the ship and packed onto a train or truck.


Container shipping services are important to global trade. Whether you are purchasing tennis shoes from China or leather goods from Australia, having an economical way to ship those goods is necessary. That is where container shipping services come into play.

Standardized Containers

By using standardized shipping containers ships, trains and trailers can be loaded and unloaded efficiently. This makes goods more affordable than if the containers were loaded and unloaded at each stop along the route.


When selecting a container shipping service, keep in mind what you are shipping. There is more to selection than the bottom line price. Are you shipping fruit, chocolate or seafood? If so, you want to choose a service that utilizes specialized reefer containers where temperature control is possible. If you are shipping machinery or odd sized equipment, you want a service that utilizes open top or flat rack containers. These more easily handle product that will not fit in a standard closed container.

Other examples of types of containers to use: open top is ideal for logs, machinery and odd sized items. Flat racks are ideal for boats, vehicles, machinery, industrial equipment. Open side are ideal for vegetables such as onions and potatoes. Tanks are used for chemicals, wine, vegetable oil.

Cargo Ships

Liner shipping is transport by ocean-going ships that ravel set routes on fixed schedules. According to World Shipping Council, there are "approximately 400 liner services."

Air Freight

Airplanes are faster but haul much less freight therefore are more expensive and less environmentally friendly.

Rail Freight

Rail is an efficient way to transport freight from a seaport to a destination across the country. Containers are moved by crane from the ship to a railroad car.

Truck Freight

A container may be loaded directly from a cargo ship or a railroad car to a tractor-trailer without having to physically touch the product.

How Freight is Shipped

Goods transported by ship can be loaded right at the manufacturer, be sealed and remain that way until arrive at the purchasers warehouse.

The manufacturer works with freight forwarder to arrange transport from manufacturer. The trucking company arrives at manufacturer and loads the product into a standardized container. Customs is the only one who may open a sealed container, for the purpose of inspection, until the container reaches its final destination. The freight forwarder decides the most cost effective port from which to ship.

How To Decide

Pricing is always going to be a key component in choosing a container shipping service. In addition to cost, it is important to choose a service that has a reputation for shipping successfully the type of product you are shipping.
