What is an Intermodal ISO Tank?
Engineered to meet global ISO (International Organization for Standardization) standards, ISO tank containers are purpose-built for liquid and gas transportation. These cylindrical tanks deliver unmatched versatility, safety, and efficiency for businesses moving liquid cargo
An ISO tank container is essentially a cylindrical tank that is typically housed within a standardized 20-foot or 40-foot frame. Its design allows businesses to ship liquids without the need to unload and reload across sea, rail, and road. ISO tanks are built to withstand the rigors of different transportation modes while keeping the cargo safe, which reduces the potential downtime of transfer operations.
Features of ISO Tanks
To safely transport a variety of liquids (some of which can be hazardous) across multiple modes of shipping, ISO tanks need to be reliable, which include:
- Durable Material Composition: Built from stainless steel with protective layers to resist corrosion, ISO tanks maintain the integrity of even the most sensitive cargo.
- Flexible Capacity Options: These tanks come in various capacities, ranging from 14,000 to 26,000 liters, tailored to meet diverse volume needs.
- Designed for Versatile Cargo: Whether carrying hazardous chemicals, food-grade liquids, or non-hazardous materials, ISO tanks provide secure containment for a wide range of commodities.
- Cargo-Specific Functionality: For added flexibility, ISO tanks can be customized to suit specific cargo requirements, such as pressurization, heating, or refrigeration.
Intermodal ISO Tanks and Rail Shipping
Rail shipping is one of the most cost-effective and sustainable transportation modes over long distances. Pairing ISO tank containers with rail logistics maximizes efficiency by streamlining operations while minimizing risk. Their compatibility with intermodal systems (such as rail and truck) provides shippers with easier transitions, reducing the time and labor cost associated with manual handling.
Industry Applications for ISO Tanks
ISO tanks’ versatility and specialized design make them the go-to choice for shippers seeking a reliable solution. Here’s some examples of commodities and products ISO tanks excel at handling:
- Chemical Industry – Acids, solvents, and petrochemicals
- Food & Beverage – Wine, edible oils, fruit juices, and syrups
- Pharmaceuticals – Sterile or temperature-sensitive liquids
- Gases – Pressurized ISO tanks for industrial gases
Why Choose ISO Tanks Over Drums or Flexibags?
When compared to other methods of transporting liquid commodities, such as drums or flexibags, ISO tank containers offer superior efficiency, cost savings, safety, and sustainability.
ISO Tank Efficiency
A single ISO tank can carry up to 26,000 liters of liquid, equivalent to roughly 80 drums. This increased volume minimizes handling, accelerates supply chain optimization, and keeps operations moving.
ISO Tank Cost Savings
With ISO tanks, fewer containers mean fewer costs. By consolidating liquid shipments into one high-capacity tank, shippers reduce freight, handling, and storage expenses. The result is a more efficient supply chain at every stage, which reduces costs in every aspect of logistics.
ISO Tank Safety
ISO tanks are specifically engineered to safely transport corrosive or volatile substances with minimized risk of leaks or contamination. Their robust construction ensures regulatory compliance, while keeping the cargo safe from outside temperature, humidity, weather conditions, and more.
ISO Tank Sustainability
Reusable for up to 30 years, ISO tanks significantly reduce reliance on single-use alternatives like flexibags, which contribute to plastic waste.

Intermodal ISO Tank Advantages
Because ISO tanks comply with ISO dimensions, they can be transferred seamlessly between ships, trains and trucks without needing to manually transfer cargo. This specialized benefit provides benefits, including logistically and environmentally.
Reduced Handling Time and Risk
ISO tanks reduce the complexity and frequency of cargo handling. With fewer touchpoints, the potential for damage and contamination drops dramatically.
Streamlined Customs Processes
When it comes to international shipping, ISO tanks ease the burden of customs. Their standardized dimensions facilitate quicker and smoother customs clearance.
Reduced Emissions and Sustainability
ISO tanks support environmentally responsible logistics, particularly when it comes to cross-ocean supply chains. By enabling direct intermodal transport, they help optimize shipping routes, reducing unnecessary detours and handling. This efficiency translates to lower emissions in cross-ocean shipping, rail, and truck.
Reusability Reduces Waste
Unlike single-use containers, ISO tanks are built for repeated use, drastically cutting down landfill waste.
Fewer Empty Return Trips
Efficient intermodal logistics reduce the need for empty container repositioning. ISO tanks streamline route planning and minimize unnecessary travel, saving fuel and cutting emissions.
Designed for Green Logistics
ISO tanks integrate seamlessly with alternative fuel-powered transport and green logistics platforms.
