How to choose a used tank container

Tank containers are large, cylindrical vessels designed to transport or store bulk liquids, gases, or powders safely and efficiently. Unlike brand-new units, used containers have already been in service before being refurbished and given a second life, making them a cost-effective and sustainable choice. But “used” doesn’t mean “lower-quality”. In fact, these containers are built to last for decades, thanks to their robust construction and strict international standards.

Tank containers are often made from high-grade stainless steel, encased in a protective frame that fits standard ISO dimensions. This means they can be easily handled, stacked, and transported by road, rail, or sea, just like any other shipping container. The typical capacity ranges from 14,000 to 26,000 litres, making them suitable for a wide variety of cargo types. 

The key features you’ll often find when it comes to used tank containers include:

• Thorough repair and inspection process: A reliable supplier will ensure each used tank container is carefully inspected and repaired to make sure it meets safety standards. 
• Deep cleaning and cleanliness certificate: A used tank container provider should ensure thorough cleaning and remove any leftover residue from previous use. You can ask for a cleanliness certificate to confirm the refurbished container is ready for use and meets industry standards.
• Third-party inspection for full transparency: The best tank container suppliers will go further and arrange an independent third-party inspection at customer request, with a full report, for absolute confidence in its condition after refurbishment.

When considering a used tank container, it’s important to look at its maintenance history, previous cargo carried, and any modifications that may have been made. These factors can influence both the price and the suitability of the container for your specific needs. 

In our experience, a well-maintained used tank container can offer excellent value for money, especially for businesses looking to optimize their logistics budget without compromising on safety or efficiency.

Common applications of used Tank Containers

Used tank containers are incredibly versatile, which is why they’re a popular choice across a range of industries. Their primary function is to transport and store bulk products with maximum safety, but their applications go far beyond that. In the chemical industry, for example, used tank containers are often employed to move solvents, acids, and other hazardous materials. Food and beverage companies use them for logistics involving edible oils, juices, and even wine, thanks to the food-grade stainless steel interiors found in many units.

In the oil and gas sector, used tank containers are an economical solution for transporting fuels, lubricants, and other petroleum products. They’re also widely used in agriculture for storing and moving liquid fertilizers or pesticides. Some companies repurpose used tank containers for static storage on-site, turning them into mobile fuel stations or water reservoirs.

Another interesting trend is the use of used tank containers in modular construction projects. Their robust design and weather resistance make them ideal for converting them into portable offices, workshops, or even living spaces. For businesses with fluctuating storage needs, renting or buying used tank containers can provide the flexibility to scale up or down – without major capital investment.

Pros and cons of buying used Tank containers

Choosing a used tank container can be a smart move, but it’s important to weigh everything up before you make a decision. One of the biggest benefits is cost savings. Used containers are significantly less expensive than new ones, allowing your business to allocate resources elsewhere. This is especially valuable for startups or companies operating on tight margins.

Another advantage is that they’re more likely to be available immediately. New tank containers can have longer lead times, but used units are typically ready for delivery. This can be crucial when you need to respond quickly to market demands or unexpected logistics challenges.

Conversely, buying used means accepting some level of wear and tear. While reputable sellers refurbish and certify their containers, there may still be cosmetic imperfections or minor repairs needed. It’s also essential to verify the container’s history: what did it previously carry? How well-maintained was it?  And does it meet the current regulatory standards for your intended use?

There’s also the question of lifespan. While a well-maintained used tank container can serve as a trusty workhorse for many years, it may not last as long as a brand-new unit. Ultimately, the decision comes down to your specific needs, budget, and risk appetite.

Choosing the right Used tank container

Once you have found a trusted supplier, discuss your requirements to determine what kind of capacity and material your used tank container needs to have. Your container partner will work with you and look at specifications including a heating/cooling system, pressure rating, valves & fittings and certification.

It’s also wise to do some due diligence before making the final decision on your used tank container…

Start by reviewing the container’s documentation: This includes maintenance records, previous cargo, and any repair or modification history. This paperwork can reveal a lot about the container’s condition and suitability for your application.

Move on to a physical inspection: Check the exterior frame for signs of corrosion, dents, or structural damage. The tank shell itself should be free from cracks, deep scratches, or pitting, especially if you plan to transport food-grade or hazardous materials. Don’t forget to inspect the manhole, valves, and gaskets for leaks or excessive wear. If the container has insulation or heating systems, test these components to ensure they’re functioning properly.

Pay close attention to the certification plates and markings: These should be legible and up to date, confirming that the container complies with relevant international standards. If possible, request a pressure test or hydrostatic test report to verify the tank’s integrity. Remember, a thorough inspection not only protects your investment but also ensures the safety of your cargo and your people.

Inspection checklist

When evaluating a used tank container, having a clear checklist can make the process much more efficient and reliable. Here’s a practical guide to help you cover all the essential points:

• Documentation review: Confirm the container’s maintenance history, previous cargo, and certification status.
• Exterior condition: Inspect the frame for rust, dents, or structural issues. Check the paintwork for signs of corrosion or damage.
• Tank shell: Look for cracks, pitting, or other surface defects. Ensure the interior is clean and free from contamination.
• Valves and fittings: Test all valves, gaskets, and seals for leaks or excessive wear. Make sure all fittings operate smoothly.
• Manhole and access points: Check for secure closures and proper sealing. Inspect gaskets for flexibility and integrity.
• Insulation and heating/cooling (if applicable): Verify that insulation is intact and heating/cooling systems are operational.
• Certification plates: Ensure all regulatory markings are present and legible. Confirm that the container meets current standards.
• Pressure test results: Request recent test reports to confirm the tank’s structural integrity.

Taking the time to follow this checklist can help you avoid costly mistakes and ensure that your used tank container will perform reliably in your operations.

Key takeaways

Used tank containers offer a cost-effective, reliable solution for transporting and storing bulk liquids, gases, or powders.
