Standard ISO Tank Containers
A standard ISO tank container features a 316L stainless steel barrel inside a carbon steel frame, making it an ideal choice for transporting various liquid products safely. This strong combination ensures the container provides reliable protection. Compared to carbon steel, 316L stainless steel is more flexible, lighter, and safer. It offers the necessary protection for food, feed, and pharmaceutical products.
The frame’s corrosion-resistant paint also helps it last longer. Furthermore, the ISO-compatible dimensions allow the container to easily fit into standard logistics systems, making it more convenient to use.
Tank Container Codes and Certifications
Most standard ISO tank containers follow the T11 T code. This makes them suitable for food-grade, unclassified, and some classified products. For more demanding products like acids, you can upgrade the T11 container to a T14 model. The T14 is stronger and more durable, making it better for strong conditions.
In addition, each container meets important international standards like ISO, CSC, TIR, UIC, and UN Portable Tank codes (including US-DOT, IMDG, and ADR 6.7). Many containers also have dual certification, such as ADR TANK 6.8 (like L4BN), which ensures they meet various legal and safety requirements.
The Benefits of Using Standard ISO Tank Containers
Choosing a standard ISO tank container for transport has several key benefits. These containers are designed to be safe, reliable, and flexible, making them perfect for shipping many different types of liquid products.
The durable design of these containers lets them handle rough conditions, which helps keep the product safe during transport. Additionally, their compliance with international standards makes it easy to use them in global supply chains. As a result, they work efficiently across different shipping methods, offering a dependable solution for businesses.

Details of standard (ISO) Tank Containers
A 20”/DN500 manlid comes with 8 swing bolts. The manlid uses a standard PTFE braided gasket, which can be replaced with other gasket materials if needed
The Unportable tank T11 features a 3-closure bottom discharge supplied by a leading global manufacturer. The discharge valve includes: a high-lift internal valve that can be closed remotely via a cable on the side of the tank container, a butterfly valve as the second closure, and a 3” BSP spigot as the third closure.
We regularly modify connections upon customer request, offering a cleanflow version or changing the BSP connection to a quick-release coupling. Our team is here to assist.
Most tank containers are designed for future installation of a bottom cabinet (floor and door) for cleaner operations and easier fitting of TIR seals
A standard tank comes with a DN80/3” connection on top. Upon request, we can add a connection for easy filling or discharge from the top. A bottom-operated top discharge is one of the possibilities, and our team can assist with the installation.
A ball valve is fitted on the top to release air during loading and discharge. Standard size is 1,5”/DN40 with BSP connection. Upon request, we can change this connection to a flanged version, 2” valve, a bottom-operated version.
For full bottom operation, we can extend the airline to the bottom (GOVR), including: a bottom-operated airline valve, piping to the bottom/rear of the tank, manometer including an 2nd valve (dimension and connection to be discussed).
A T11 tank container includes a safety valve that opens at 4,4 bar (10% above the test pressure). In addition to the pressure-only version, there is also an optional pressure + vacuum version. Each tank container is designed for future fitment of a bursting disc. (needed for both T12 and T14 specification).
The frame is made of mild steel and meets the ISO dimensions of a 20ft box container. The barrel connects to the frame and forms part of the integral construction. Therefore, top rails are not needed but can be added upon request.
Each tank container comes with a stick-on analogue thermometer that reads from -20 to a maximum of 160 degrees C. Upon request, we can add a digital version or thermometers with a probe for more accurate readings of the product temperature.
Each tank container has an anti-slip ladder on the rear side for easy access to the top of the container
Each container is fitted with aluminum walkway to access the manlid, Safety relief valve and airline. The minimum layout has 1 longitudinal walkway and transverse sections between the spill boxes. On request additional walkway can be added as well as spill box covers for a clean operation and easier fitment of TIR seals.
On request one or 2 collapsible handrails can be fitted, top as well as bottom operated.
Each tank container is fitted with minimum 8 steam runs to be able to heat up the product with warm water or steel. The covered area is 8 SQM. On request the number of steam runs can be upgraded to 12 runs. In addition a water glycol heated system can be added.
A small part of the fleet is non insulated, the majority has 50mm insulation and cladding. The insulation material varies from PU, Rockwool, glass wool or a combination. The cladding material is either aluminum, GRP or Stainless steel.
