Are you interested in knowing more about the world of intermodal freight? But does all the terminology overwhelm you? Well, there’s no need to panic, this blog has everything you need to know in simpler words. Read on to learn more about the wonderful world of ocean freight!
Sea containers are an integral part of intermodal freight shipping. Without these big metal boxes, there would be little to no cause for ocean shipping. There are various types of sea containers to choose from, but before we get into that, let’s start at the basics.
What are sea containers?
Sea containers are large boxes which are made of metal and used to store or ship different cargo. Containerization is the method of transporting freight by placing large amounts of cargo into containers and shipping it to the desired destination.
Each container type serves a unique purpose and is designed to carry specific cargo. Let’s go through a couple of sea containers and their dimensions.
11 common sea containers: dimensions and capacity
Just like there are many types of fish in the ocean, there are also many types of sea containers. Each one serves a unique purpose to the industry. You want to be as informed as possible when purchasing your container. It’s beneficial to know what’s what, and how you can utilize them to suit your needs best. Let’s go through a few and see which ones sound familiar to you.
20ft Standard container
A 20ft standard container is, in the simplest way, exactly as the name suggests. A standard dry shipping container comes with an external length of 20ft. This container-type is popular and most commonly purchased. It’s ideal for shipping any dry cargo.

What is the shipping process for intermodal sea containers?
After all the fishing is done for the types of sea containers you’ll need, there is a process to follow when it comes to cargo shipping. There are seven steps you should keep in mind:
Steps |
Process |
Export haulage | The process of transferring the desired cargo from the shipper’s premises to the forwarder’s warehouse. |
Export customs clearance | Required by the country of origin to allow your cargo to leave the country smoothly. Remember supporting documents! |
Origin handling | The cargo is unloaded and set up where it’s inspected very carefully. Usually handled by the freight forwarder. |
Sea freight | Sea freight is the method of transporting goods via ocean shipping. Typically handled by the shipping line under contract with freight forwarders. |
Import customs clearance | Required by authorities of the destination country for all cargo being shipped into their country. |
Destination handling | Necessary documentation is received and processed. The container is collected from the port and brought to the destination warehouse. It’s unpacked, checked and sent for collection or onward travel. |
Import haulage | Deliver the cargo to the consigneeWhat is a consignee? When transporting freight (by ocean, air, or land), there are two parties involved — one who is shipping and the other who is receiving the freight. The recipient of the goods b... More from the import warehouse. Usually done via the freight forwarder or a local delivery company. |
Knowing this process can help you understand how shipping works and perhaps even help you save on import haulage and customs clearance charges . There are some other ways you can save money by using sea freight, and that’s by considering used or second-hand sea containers.
Used sea containers: popularity and benefits
Second-hand sea containers come in handy when you’re on a tight budget. Used sea containers offer all the same advantages as a brand new one, at only a portion of the cost. They are easily modifiable which makes them versatile and highly popular. Consider these container types when you don’t need a brand new solution immediately, but remember that the cost of used sea containers also depends on condition.
