Imagine you’ve got a consignment order to ship bulk wine from Port of Livorno, Italy to Port of Hamburg, Germany. Considering that wine goes under perishable products, it requires the right temperature to retain its freshness and shelf life. Which container would you choose to transport this beverage?

The answer is an ISOtainer. It’s the easiest, safest, and most efficient way to transport your liquid items. It’s specially designed to carry bulk food, liquid, chemicals.

But before we use the term ISOtainer again, let’s understand what exactly it means.

What is an ISOtainer?

ISOtainers (or ISO tank containers) are special containers to transport hazardous and non-hazardous liquids in bulk. These containers follow the standards of the International Organization for Standardization (ISO) which give tanks the credibility of safety and performance.

ISOtainers are intermodal containers used to transport liquids, powders, and liquefied gases safely. Tanks are cost-effective and reduce shipping and handling costs. So, with this container type, you can rest assured that your cargo is loaded and unloaded hassle-free.

A tank is a cylindrical-shaped container, primarily made of stainless steel. There’s insulation and a protective layer of either aluminum or polyurethane to protect the container from corrosion and harsh weather conditions.

The fact that you can transport thousands of gallons of liquid in one shipment is a huge advantage, and of course, it’s a time saver! ISOtainer transports liquid hassle-free. You can learn more about ISO Tank containers and their types and uses in this separate blog.

Why choose ISOtainer? 

There are many reasons why ISOtainer makes for an ideal container for your bulk cargo, especially if you’re shipping liquids and powders. Moreover, the ISO certification gives tanks a seal of quality assurance. Let’s look at the 5 most common benefits of using an ISOtainer.

Reliability

When it comes to ISOtainer, reliability is the first advantage that comes to mind. If you’re transporting bulk liquids, it’s a given that you can rely on ISO tank containers the most. It’s spill-proof and a cost-effective option for your shipment. Tanks go through several tests and inspections before it gets to your doorstep. Thus, we recommend you check for the ISO mark when you buy or lease a tank container.

Safety

Safety is another big benefit of ISOtainers. Each tank type is designed for specific goods – chemicals, food, and liquids. The best part is; you can’t use a chemical-grade tank as food cargo — ensuring safety. An ISOtainer goes through deep cleaning and inspection before and after the cargo is loaded and unloaded.

Environment-friendly

The leakage-proof feature of ISO tanks makes these containers environment-friendly. This also means that if you are transporting hazardous chemicals, they’ll be safely stored and shipped. Moreover, ISOtainers have a long shelf life of at least 25-30 years. You can reuse it as many times as you want just with routine checks and inspections.

Efficiency

ISOtainers are easy to handle and maneuver. They require minimal manual effort during the loading and unloading process. Tanks can carry a large number of goods at a time too, which is a blessing. For example, a 20ft ISO tank can carry 24,000 liters of liquid as compared to a 20ft container with drums, which accommodates only 15,000 liters.

Security

Each tank comes with a unique BIC code making it easy for you to track these containers. They provide secure storage and can be transported by road, rail, and sea. The structural design of the ISOtainer helps resist harsh weather and road conditions.

Design and specifications of ISOtainer

Since ISOtainer follows the ISO-certified standards, the dimensions and specifications are universally accepted. The fixed set of specifications ensures efficiency, quality, safety, and consistency of every tank in the market.

So, whenever you’re getting a tank container, make sure to check for the ISO seal that guarantees reliability and stability to transport liquids, gases, and chemicals.

ISOtainer comes in 20ft and 40ft dimensions. However, the 20ft tank is the most common one. It has a carrying capacity of up to 26,000 liters.

Before we get into more details on it, let’s take a quick look at its design and specifications.

A standard ISOtainer is made with a stable steel frame to hold the tank in place and secure the cargo.

It’s 20ft (6.58m) long, 8ft (2.438m) wide and 8.6ft (2.59m) high. Below are the other specifications of an ISOtainer.

What kind of goods can an ISOtainer carry?

ISO tank containers come in a wide range of types, each suitable for a specific good. They can carry both hazardous and non-hazardous liquids. At large, this includes explosives, chemicals, flammable, and food/dairy products.

While we said this earlier, a tank makes a viable shipping option for your liquid goods (both hazardous and non-hazardous), it’s important to know the types of cargo certified to be transported in tanks.

Here is a list of products that you’re allowed to carry:

• Milk and milk products
• Alcoholic beverages
• Non-alcoholic
• Liquefied sugar
• Hydrogen peroxide
• Sulfur acid
• Chemicals
• Vegetable oils
• Flammable liquefied gases
• Liquid resins
• Molasses

What makes ISOtainer safe?

You’ve already read about the benefits of ISOtainers. But what makes them safe to use? Let’s find out.

There are different types of tank containers available in the market today. With a wide range of variety at your service, it’s easier to figure out which one suits your need the best.

One of the first points that come to mind when writing about tanks is that each tank type comes with a specific purpose.

For easy categorization of cargos, the International Maritime Dangerous Goods Code (IMO) originally classified tanks into IMO Type 1, Type 2, and Type 5. This was later replaced by the “T” code to include more specific details.

The classification of tanks helps to get more clarity on the types of liquid you can transport in a particular tank type.

As per ISO standards, if you’re using a chemical-grade tank, you can’t use the same container to carry food products. These tanks go through thorough inspections both before loading and after unloading. This ensures safety and hygiene at all levels.

You can read more about the different tank types here.

Benefits of shipping goods in an ISOtainer

ISOtainers are globally approved and come with an assurance of quality, safety and reliability. While handling ISOtainers, your priority is to ensure cleanliness. Make sure that your container is thoroughly cleaned and inspected before you pick it up. Ask for valid documents that stated this in writing.

Given that chemical-grade tanks can’t be used for food-grade cargo, it makes tank containers one level safer.

Let’s dive into a few other benefits of shipping goods in an ISOtainer:

• You can ship a huge quantity of bulk cargo, especially, liquid goods in a tank. This makes the shipping cost lesser than other container shipments.
• The loading and unloading process requires minimal labor. This cuts down your maintenance cost but increases your resale value.
• ISOtainers are great for your temperature-sensitive cargo and can be shipped by both road and ocean.
• If you’re the one who works towards a greener environment, ISOtainer is your safe bet. Their specially designed structure combats product spillage, saves more fuel, and reduces carbon dioxide emissions by up to 70 percent.
• Tanks have a longer shelf life. This means you can use and reuse your container with just minor annual inspections.
• You can transport both hazardous and non-hazardous goods without worrying about their safety. Tanks are designed for that.

Now that you’ve read about ISOtainer and its benefits, it’s time to get an understanding of flexitanks and how it’s different from tanks. We’ll also give you an insight into the best choice for you. Let’s dive in then.

ISOtainer vs Flexitank: Which one is for you?

ISOtainer and flexitank are both used to transport bulk liquids efficiently. However, how you choose to transport your cargo depends on your product type, origin, and destination locations.

Let’s take a look at some differences between both these types of containers. Flexitanks can turn out reasonable when your cargo is non-hazardous such as milk and milk products, vegetable oils, non-alcoholic beverages (juice), or liquefied sugar (depending on where you’re shipping to and from).

However, tanks are more accommodative for both non-hazardous and hazardous cargo. The structure of tank containers is suitable to maintain the required temperature for cargos and to provide a safer environment for storage and transportation.

Flexitank has a higher chance of spillage (which is very common) and can harm the environment. Tanks are more reliable that way. They are leakage-proof and cut down the environmental impact by 70%.

Having said that, keep in mind that tanks incur a high repositioning cost if there’s no two-way shipment. It can lead to an increased ocean freight rate. Flexitanks, however, have a better freight advantage here.

Choosing a tank or a flexitank depends on your requirements. You must understand your needs. We recommend you to weigh your long-term goals first – the time you need the container for, its environmental impact, product or cargo you’re shipping, and of course, reliability and safety before selecting either of them.

So, whether you choose a tank container or a flexitank, the most important point to keep in mind is the price. Getting your hands on a special container such as tanks at a price that doesn’t burn a hole in your pocket is essential. And we understand that. That’s why, at xChange, we help you get the container you want at the most competitive price with market transparency.

Let’s break it down together.

Step 1: Identify the Purpose

Start by asking yourself: What am I using this container for?

• Transport – Will it travel long distances? If yes, focus on standard dry containers or reefers for perishables.
• Storage – Is it staying in one location? Look into used ISO containers for cost savings.
• Modification – Planning a workshop, pop-up space, or remote office? Go for containers that are easy to customize like high-cube or side-door units.

Knowing the purpose helps you eliminate unnecessary options right away.

Step 2: Choose the Right Size

The most common sizes are 20ft and 40ft, but that doesn’t mean they’re the only ones.

• 10ft – Great for tight spaces or small storage needs
• 20ft – Ideal for general use, easy to transport
• 40ft – Best for bulk cargo or large-scale storage

If you’re moving heavy or high-volume loads, a 40ft ISO container will offer the most value per cubic foot.

Step 3: Consider Special Features

Think about any cargo-specific requirements:

• Does your cargo need ventilation? → Try ventilated containers.
• Need temperature control? → A reefer is the way to go.
• Need access from the side? → Side-door containers make loading much easier.
• Working in a tough environment? → Go with corrosion-resistant, reinforced steel builds.

These small details make a big difference in the container’s performance.

Step 4: Think About Portability and Handling

If you’ll be moving the container around regularly—or placing it in tight or uneven areas—handling becomes a key factor.
