Shipping containers aid the transporting of items as they provide temporary storage for the goods. They are used for carrying various types of cargo in varying conditions, so they can be constructed out of one of several different materials. The dimensions of a typical shipping container are usually between 10 and 40 feet long. They are typically eight feed wide and can be between 8 feet 6 inches and 9 feet six inches high.

When looking at hiring or purchasing a container it is important to consider their rating, tare mass or weight, and payload. The rating is the top weight allowed to be carried, including the weight of the unit itself. The mass or tare weight relates to the weight of the empty container, albeit under normal conditions. The payload is the weight the unit is allowed to carry, though this figure may be affected according to local laws, especially when being transported by road. Rating, tare weights and payloads appear on stickers attached to the shipping container. Stickers with identification codes, showing details of the owner and its specific number, must also appear both on the inside and inside of the unit. This information is essential when tracing, and monitoring the movement of the cargo and the container.

There are basically two classifications of container, and these are relevant to the type of cargo being carried. The most common type is dry cargo or general purpose. These units are very strongly constructed and are also waterproofed. There may also be a door built into a side wall to give access to the container. The second grouping is for special cargoes, such as storage tanks for the transportation of liquids such as chemicals, or thermal containers for fruit, vegetables, meat, and other perishables.

The variety of unit you use will depend on the type of cargo you wish to transport. It is essential that you use only containers that are fit for the type of job required. While most shipping companies will be able to advise you accordingly, it is good practice to enquire about which kind of containers they have available. Knowledge about the different types and classifications of shipping containers will help you in making your decision.
