What is transported in tank containers?
Tank containers, also known as ISO tanks, simply tanks or tanktainers, represent a key element of modern logistics and transportation of liquids, gases and bulk materials. These specially designed containers meet international ISO standards, making them universal and suitable for various types of transportation, including road, rail and maritime. In this article, we will take a detailed look at what can be transported in tank containers, their construction, types and advantages.
What is a tank container?
A container tank, also known as a tanktainer, is a type of intermodal container designed for transporting liquids, gases and some bulk materials. This cylindrical container is made of stainless steel and surrounded by an insulation layer, which is usually made of polyurethane and aluminum. These containers are constructed according to ISO standards, which ensures their compatibility with various types of transportation, such as road, rail and maritime transport.
Typical capacity of tank containers ranges between 17,500 and 26,000 liters, with larger units also available. Special containers for cryogenic substances or bulk materials may have specific design properties.
What is transported in tank containers?
1. Hazardous substances
One of the key uses of tank containers is the transportation of hazardous substances. For this purpose, containers must meet strict international standards, such as ADR, IMDG or RID. Typical hazardous substances include:
- Chemicals: acids (such as sulfuric, hydrochloric), bases, solvents, peroxides.
- Petroleum products: gasoline, diesel, lubricating oils.
- Liquefied gases: LPG (liquefied petroleum gas), ammonia, chlorine.
- Toxic and corrosive substances: oxides, hydroxides, toxic liquids.
2. Food products
Thanks to hygienic stainless steel construction and easy cleanability, tank containers are ideal for transporting food products, such as:
- Liquids: juices, milk, wine, edible oils.
- Alcoholic beverages: beer, spirits, wines.
- Sugar solutions or other liquid food raw materials.
3. Industrial liquids
Tank containers enable the transportation of industrial liquids, such as:
- Liquid fertilizers, such as ammonia.
- Lubricating oils and chemical additives.
- Special chemicals used in the manufacture of plastics and synthetic materials.
4. Bulk and powder materials
Special tank containers, such as silo tanks, are designed for transporting bulk materials, such as:
- Cement, lime, kaolin.
- Powder chemicals.
- Food powders, such as cocoa or dried milk.
5. Cryogenic substances
T75 ISO tanks are designed for transporting cryogenic substances, such as:
- Liquid oxygen (LOX).
- Liquid nitrogen (LIN).
- Liquid hydrogen (LH2).
Types of tank containers
1. Standard ISO tanks (T11)
The most common type of tanker, which is used for transporting a wide range of liquids, including hazardous ones.
2. Food-grade tanks
Certified tanks designed for transporting food products. These tanks require strict hygiene standards.
3. Reefer tanks
Tanks with temperature control capability, ideal for transporting temperature-sensitive liquids.
4. T50 tanks
Tanks designed for transporting liquefied gases under pressure.
5. T75 cryogenic tanks
Used for transporting substances at extremely low temperatures.
Advantages of transportation in tank containers
1. Safety
Thanks to highly resistant materials and construction, maximum transportation safety is ensured.
2. Versatility
Thanks to ISO standards, tanks are flexibly usable in various types of transportation.
3. Hygiene
Stainless steel construction and easy cleanability make these tanks ideal for transporting food and pharmaceutical substances.
4. Efficiency
Compared to traditional packaging, tanks allow for transporting larger volumes of substances.
5. Economic sustainability
Tanks have a lifespan of up to 30 years, which reduces costs in the long term.
How does transportation in tank containers proceed?
- Tank preparation: Thorough cleaning before loading.
- Loading: Filling by gravity or pumping system.
- Transport: Tanks are secured to road vehicles, railway wagons or ships.
- Unloading: By gravity or pressure system.
- Cleaning: After unloading, the tank is cleaned again.

Spare Parts for Shipping Containers Spain
Spare parts for shipping containers are an essential part of the global maritime logistics system. Without them, the thousands of containers that travel the world’s oceans and roads every day would not be able to be maintained in working order. Whether you’re looking for a replacement door handle, a new lock, a gasket or a complete floor, this guide will provide you with all the information you need to find the right parts, install them and maintain them — with a special focus on availability and suppliers in Spain and surrounding countries.
Container Units 20′ – 6m (Construction Unit)
20′ (6 meter) construction cells are one of the most important elements of modern construction and temporary project solutions. These mobile units, created from the conversion of shipping containers, have become an indispensable tool for builders, designers and construction managers around the world.
Demurrage: Port Storage Fees
Demurrage is a time-based fee charged when loaded shipping containers remain in a port or terminal longer than the allotted free time. The term comes from the French word demeurer, meaning “to remain or linger”, and originally arose in the context of ship chartering in the maritime trade. In modern container shipping, demurrage serves as a financial penalty and incentive mechanism to ensure the efficient movement of containers through ports and prevent their indefinite storage at terminals.
