The intermodal container has been a fixture in the shipping industry for decades. Being one of the pillars of the success of intermodal shipping seen as the best way to transport goods over long distances, intermodal freight containers are now being used more than ever!
Even though there are many different types of intermodal containers, they all serve one purpose: to make transporting goods easier and more cost-effective.
In this blog post, we’ll discuss what is an intermodal container, its average lifespan, intermodal shipping container specifications, the different intermodal containers, and much more!
The Container Industry: Growth and Evolution
The industry has been rapidly expanding over the past few years.
What was once a laborious and slow shipping process, intermodal container shipping is now streamlined and efficient, spreading across industries including automotive, food and beverage, retail goods, manufacturers, and much more.
Invention of the intermodal freight container
The first successful intermodal shipping container is said to have been designed in 1956 by an American trucking entrepreneur named Malcom McLean.
One morning in the late 1930s, after driving his truck from Fayetteville, North Carolina, to Hoboken, New Jersey, McLean was informed that he would have to wait until the terminal crew would unstack the pallets from his truck.
Why? Because they first had to unload all of the trucks that arrived before him.
Malcom soon recognized that he was watching both time and money wasting away, and the idea of containerization was born. But, it would still take McLean nearly 20 years to start seeing the first intermodal containers in action.
The evolution of containerization
Since its modernization, intermodal transport has been a leading industry in the country and across borders.
The use of intermodal containers has revolutionized global trade and transportation by allowing cargo to be transferred seamlessly between different modes of transportation, such as trucks, trains, and ships, without repackaging the goods.
In 2012, 20.5 million intermodal containers were in existence. Today, there are said to be 600 million shipping containers in use at any given time.
What Is an Intermodal Container?
The intermodal container (or cargo container) is an intermodal freight transport system used primarily in international trade. They are built to ISO standards for seamless use across various transportation methods.
So, what is an intermodal container? They are durable, standardized containers that can hold anything from goods to liquids to heavy machinery, enabling efficient transportation through intermodal shipping.
What is intermodal containerization?
Containerization, in short, is the process of transporting goods in ISO-standard containers.
The rise of International shipping containers with the ISO standardization
The ISO standardization for intermodal cargo containers considerably improved the importation and exportation process through the seamless international shipping of goods.
Indeed, intermodal ISO containers respect specific international standardized sizes fixed by the International Organization for Standardization. This system helped the carriers optimize their fleets and transport containers for several logistics industry sectors.
Container characteristics and regulations
The most common type, dry freight containers, is commonly referred to as intermodal or shipping containers. They are usually 8 feet wide by 8.6 feet in height.
However, in recent years, high cube containers measuring 9.6 feet high have become more popular.
Containers come with a door at either end to be quickly loaded and offer weather protection and security against theft.
The average life span of an intermodal container is 25 years.
8 Different Types of Intermodal Containers
To answer the question, “what are the two types of intermodal containers?”, it’s important to note that intermodal containers can be broadly classified into standard containers and specialized containers. Below are key intermodal container types:
Dry freight container
The most common type makes up 90% of modern intermodal shipping containers.
Refrigerated containers
Intermodal cargo containers with refrigeration systems make up 6% of the world’s cargo shipments.
Open-top container
Compared to a solid roof, open-top containers have an open-top covered by a tarpaulin. This allows big and bulky items to be shipped and loaded from the top by a crane.
Flat rack container
A flat rack container is used to transport or store goods that have a specific size. The container, as the name implies, is flat, and cargo is loaded from the top or side.
Tank container
Intermodal tank containers are used to safely store and transport liquids and gases, including corrosive or flammable liquids, such as acids and gasoline.
Heated Intermodal Shipping Container
Heated containers are temperature-controlled intermodal containers designed to carry temperature-sensitive goods, offering better protection in severe weather/climate situations.
Insulated containers
Intermodal containers are insulated to protect the cargo from external elements and maintain the initial temperature.
Ventilated Containers
Ventilated intermodal containers are designed with a special ventilation system that prevents the buildup of condensation/moisture inside.
These intermodal freight containers cater to various industries with their specialized features.
Shipping Container Specifications
What is the standard size of a shipping container?
The standard intermodal container is a 20-foot long shipping container
Note that a standardized unit was born out of that standard: The Twenty-foot Equivalent Unit or TEU. It’s used as an inexact size reference for any container ship or intermodal container. One could say, “It is a 1 TEU or a 2 TEU”.
The twenty-foot containers have an internal floor area of 146 sq. ft. and 1,172 cubic ft. of volume and are either 8.6 feet to 9.6 in height.
The weight capacity for this size of intermodal container is approximately 55,126.9 lbs or 25,000 kg.
What is the biggest shipping container size?
The largest container you can find on the market is the 53-foot High Cube Container.
Those fifty-three-foot containers are made for general purposes and specifically for international trade.
Indeed, these larger-sized shipping containers have 60% more capacity than standard 40-foot containers. Especially among rail and intermodal marine container transportation, this gain represents a significant advantage when shipping merchandise abroad.
Knowing the intermodal shipping container specifications helps businesses choose the best container for their needs.
The pallet-wide containers’ sizing
You might have also heard of “pallet-wide” containers.
These are primarily European freight containers that are slightly wider than the ISO containers, built for optimal use of the internal capacity.
Indeed, the standard size of Euro-pallets is different from the ones in North America. Depending on the dimensions of the container (20-foot, 40-foot, or 45-foot), these might carry up to 7 extra Euro-pallets, representing a significant benefit for the haulers.

The basics of intermodal transportation pricing
The price of intermodal transport is generally characterized by the linehaul charges and fuel costs. Intermodal carriers determine pricing by breaking them down into these two main components.
Fuel Surcharge – This is the cost of fuel incorporated into intermodal transportation pricing and is subject to change due to fluctuations in oil prices.
Drayage – This is the cost of moving intermodal containers from short distances and includes accessorial services and costs such as receiving, unloading, loading, and other transport terminal charges.
How do I manage intermodal container costs and shipping?
Intermodal transportation rates are generally negotiated on a per-move/ per project, on-the-spot one-off, or pre-determined contracted rates. Contact us for more information about intermodal pricing or to get a quote.
