A 20ft used tank container — also called a 20-foot ISO tank container — is a proven stainless-steel unit for sale designed for safe transport and storage of bulk liquids by road, rail, or sea. Built to ISO standards with a cylindrical tank secured within a durable steel frame, it delivers structural integrity and leak prevention you own outright at a lower cost than new.
What is a used ISO tank container? Previously in service, each unit has been inspected, tested, and certified for continued use. While cosmetic wear such as minor dents, scuffs, or surface rust may be present, all seals, valves, and internal linings remain fully functional for dependable liquid logistics.
Perfect for chemicals, food-grade liquids, industrial applications, and multi-modal bulk liquid transport where ISO-certified tank capacity and cost efficiency matter.
