ISO Tank Containers
Tank containers for liquid transport, including T11 requests. Separate from dry cargo boxes. Compare options and request pricing.
Choosing the right option
Specify the tank and the intended contents together. ISO tanks are a separate request from dry shipping containers; a T-code alone does not define every requirement.
| Option | What to compare | Include in your request |
|---|---|---|
| T11 requests | Use T11 as a starting reference, then identify the required tank configuration. | Intended contents, capacity, connections and documentation. |
| Other T-codes or configurations | State the required code or specification instead of substituting a different tank. | Known specification, process needs and any equipment constraints. |
| Condition and history | Request the history and documents for the particular tank offered. | Acceptable condition, prior-content restrictions and required records. |
Applications to discuss
- ISO tank sourcing against an existing specification
- Replacement tank-container requests
Before requesting your quote
- Identify contents and required capacity.
- Provide the required code/specification and fittings.
- List documentation, destination and timing requirements.
- Confirm the particular tank and application before accepting a quote.

An ISO tank container is a pressure vessel set inside a standard-size steel frame, built to carry bulk liquids by road, rail and sea. Wholesale Industry handles ISO tank container requests for T11 tanks and other specifications, including T14, T20 and T22, with the specific tank, its history and its records confirmed before you accept a quote.
What an ISO tank container is
ISO tanks combine a cylindrical tank with an ISO frame and corner castings, so the tank can be lifted, stacked and moved like any intermodal container. Where an IBC tote or rigid tank holds hundreds of gallons, an ISO tank carries a full bulk load in one unit. They are a separate request from dry shipping containers, even though both share the intermodal frame.
T11 and other T-codes
The T-code on a tank refers to a portable tank instruction in the hazardous materials regulations. Each instruction sets minimum requirements such as test pressure, shell thickness, bottom-opening arrangement and pressure relief. The substance you ship determines which instruction applies; your shipper or compliance team makes that call, and the regulations allow substitution only in specific cases.
| Request | When to use it | Include |
|---|---|---|
| T11 ISO tank | Your contents call for a T11 tank, or T11 is your starting reference for a general liquid | Contents, capacity, connections, heating or insulation, records |
| T14, T20, T22 or another specification | Your contents or process require a specific code or a technical specification | The exact code or spec, contents, fittings and equipment constraints |
T11 identifies a tank instruction, not a single capacity or a dry box. Do not substitute one code for another to save time; state the code you need and let the offered tank be reviewed against it.
What to specify
Contents
Name the product, its hazard class if any, density and loading temperature. Contents drive the tank code, lining or material needs and any prior-cargo restrictions.
Tank configuration
Capacity, top and bottom valves, manlid, connections, and whether you need steam heating, insulation or other temperature control.
History and records
Ask for the data plate details, inspection and test dates, and the prior-cargo and cleaning records for the particular tank offered.
Condition and prior cargo
For an ISO tank, history matters as much as condition. A tank that carried an incompatible product may need specialized cleaning or may be unsuitable for your contents altogether, and food or sensitive products often call for tanks with a documented prior-cargo record. Review the inspection status on the data plate: a tank due for its next periodic inspection may need that work done before it can be filled for transport. Request photos and documents for the specific tank before you accept a quote.
Handling, placement and loading
An ISO tank moves on a container chassis by road, on rail flatcars and on ships, and it is lifted by its corner castings with equipment rated for the loaded or empty weight. Before ordering, confirm how the tank will reach your site and how it will be set down: on a chassis, on the ground or on a stand. Check that your loading and unloading connections, hoses and pumps match the tank's valves and fittings, and that you have the venting, grounding and spill containment your process and site rules require. If your product must be kept warm, confirm the heating arrangement and that you have the steam or power supply to run it. Planning these details early avoids a tank that arrives on time but cannot be filled or discharged.
Common applications
- Chemical and industrial liquid transport between plants, terminals and ports.
- Replacing or adding tanks to an existing fleet built to a known specification.
- Food and beverage ingredients, where prior-cargo history is reviewed closely.
- On-site bulk liquid storage where the tank's frame and fittings suit the site.
ISO tank container checklist
- Contents, hazard information and required T-code or specification.
- Capacity, fittings, valves and temperature requirements.
- Acceptable condition and prior-cargo restrictions.
- Required inspection records and documentation.
- Destination, delivery or pickup arrangements, quantity and timing.
Every ISO tank request is a sourcing request. Confirm the particular tank and its suitability for your application before accepting the quote.

Frequently asked questions
What does T11 mean on an ISO tank container?
T11 is a portable tank instruction code from the hazardous materials regulations. It sets minimum requirements such as test pressure, shell thickness, bottom openings and pressure relief. It does not define a single capacity or every fitting, so state your contents and full configuration along with the code.
Can I use a T11 tank instead of a T14 or T22?
Not as a general rule. The required instruction is set by the substance being shipped, and the regulations allow substitution only in specific cases. Your shipper or compliance team should confirm the required code, and the offered tank is then reviewed against it before you accept a quote.
What records should I ask for with an ISO tank?
Ask for the data plate information, the dates of the most recent inspection and test, prior-cargo history and cleaning records for the specific tank. Request photos as well. These details are confirmed for the particular tank offered before you accept the quote.
Is an ISO tank the same as a shipping container?
No. Both use an intermodal frame with corner castings, but an ISO tank container is a pressure vessel for bulk liquids, while a dry shipping container is an enclosed steel box for general cargo and storage. They are requested, inspected and evaluated separately, with different records and condition checks.
Can an ISO tank be used for food products?
Some tanks are used for food and beverage liquids, but suitability depends on the tank's construction, prior cargo and cleaning history, and your own regulatory requirements. Tell us the product and the documentation you need, and confirm suitability for your application before accepting a quote.
