ISO Tank Container: Dimensions, Types, and Feature Specifications

ISO tank container is a specialized intermodal container designed to transport liquid or gas in large volumes in compliance with International Organization for Standardization (ISO) standards and UN-IMO regulations for portable tanks. Its structure consists of a cylindrical stainless steel tank mounted within a standard steel frame fitted with corner fittings, allowing it to be lifted and moved using the same equipment as standard containers.

Transporting bulk liquid and gas cargo requires a vessel that is safe, efficient, and compatible with multiple modes of transport, from ocean vessels and railways to road trucks. ISO Tank Containers are widely used by petrochemical companies, the food and beverage industry, pharmaceutical manufacturers, and hazardous chemical producers that require internationally certified and safe transportation facilities.

Standard dimensions follow the 20-foot container format: approximately 6 meters in length, 2.4 meters in width, and 2.4 to 2.5 meters in height. ISO Tank Container capacity generally ranges from 21,000 to 40,000 liters, depending on the type.

What makes the ISO Tank Container the industry’s preferred choice is its intermodal capability. Cargo does not need to be transferred when the mode of transport changes. A single tank travels from the factory directly to the port and then onto a truck, with no risk of contamination or spillage.

ISO Tank Containers are available in a wide range of types and capacities, from food-grade liquid tanks to cryogenic gas tanks, making them adaptable to diverse operational requirements. Tradecorp, as a trusted container company, provides ISO Tank Container sales and rental services with a straightforward, transparent, and efficient process.

ISO Tank Container Dimensions

ISO Tank Container dimensions conform to internationally established standards set by ISO (International Organization for Standardization). The following are the standard dimensions commonly used:

The 20-foot ISO Tank Container is the most common size and the most widely available on the market. The identification code for a 20-foot ISO tank uses the prefix “22K” followed by a number or letter corresponding to its cargo type, per ISO 6346 standard.

The 40-foot ISO Tank Container offers significantly greater capacity and is better suited for heavy industrial shipping requirements or projects involving very high cargo volumes.

Understanding the correct ISO Tank Container dimensions allows companies to calculate fleet requirements more efficiently and substantially reduce logistics costs.

ISO Tank Container Types

ISO Tank Container types are differentiated by the type of cargo they carry, working pressure, and the inner lining material of the tank. This classification system is known as the T-Code, established under international regulations including the IMDG (International Maritime Dangerous Goods) Code.

The following table lists ISO Tank Container types and their functions:

Each ISO Tank Container type is engineered to meet specific safety standards. Selecting the right type is not merely a matter of capacity, it is a matter of safety, regulatory compliance, and cargo integrity throughout the shipping process.

ISO Tank Container Feature Specifications

ISO Tank Containers are equipped with a range of technical features that ensure cargo safety throughout the shipping process. The following are the key feature specifications to know:

• Tank Material. The primary tank is constructed from corrosion-resistant stainless steel, making it suitable for food-grade liquids as well as aggressive chemicals.
• Insulation Lining. Polyurethane or rockwool insulation options are available to maintain cargo temperature during transit, particularly for temperature-sensitive shipments.
• Valve System. Equipped with a bottom discharge valve, a top manhole for filling, and a safety relief valve to manage excess pressure.
• Corner Fittings. Conform to ISO standards, ensuring compatibility with spreader cranes, forklifts, and locking systems on vessels and trucks.
• Working Pressure. Depending on the type, design pressure ranges from 1.5 bar (for light liquids) to over 22.5 bar (for T50 gas tanks).
• Certification. ISO Tank Containers manufactured to standard carry a data plate listing the certificate number, design pressure, year of manufacture, and the cargo specifications permitted.
• Stacking Capability. Thanks to the standard steel frame and corner fittings, ISO Tank Containers can be stacked at ports and aboard vessels just like standard containers, optimizing storage space.

ISO Tank Container Capacity

ISO Tank Container capacity varies by type. The following table shows the capacity ranges commonly available:

Selecting the appropriate ISO Tank Container capacity requires consideration of shipment volume per period, cargo type, and vehicle weight regulations applicable along the intended distribution route.

Cargo That Can Be Transported in an ISO Tank Container

One of the primary advantages of the ISO Tank Container is its flexibility in transporting a wide range of cargo, from food-grade liquids to high-pressure hazardous gases.

• Food-Grade Liquids (Non-Hazardous): Food-grade or T1/T11 ISO Tank Containers are used to transport drinking water, juice, milk, wine, beer, cooking oil, and syrup. The smooth stainless steel tank surface ensures zero contamination during shipment.
• Industrial Chemicals: Non-hazardous chemical liquids such as industrial solvents and lubricating oils use T4 or T11 tanks. Strong acids such as hydrochloric acid (HCl) and other corrosive chemicals require T14 tanks or rubber-lined tanks.
• Liquefied and Cryogenic Gases: Liquefied gases, including LPG, propane, butane, and ammonia, are transported using T50 ISO tanks. Cryogenic gases, such as LNG, liquid oxygen, and liquid nitrogen, require T75 ISO tanks with dedicated insulation systems.
• Temperature-Sensitive Cargo: Products such as fresh dairy products, certain juices, and some pharmaceutical products require reefer ISO tanks capable of maintaining controlled temperatures throughout transit.

The type of cargo that may be transported is determined by the T-Code, the inner tank lining type, and the IMDG/ADR regulations applicable to hazardous materials. Always consult with your ISO Tank Container provider to confirm specifications appropriate for your cargo.
