International standards organization tanks (ISO tanks) are large, often customized tanks that hold water, foodstuffs, hydrogen peroxide, gases and other materials both hazardous and non-hazardous. For more volatile substances, refrigerated and heated ISO containers with specialized linings are available.

ISO tank manufacturers can help companies choose the right tank for the job. In fact, manufacturers rarely list their prices upfront. You will usually have to tell them precisely what you need to get a quote. ISO tanks pricing and costs depend on a variety of factors. You may need modified ISO containers, but there is also a large demand for cost saving options, such as:

1. Used ISO tanks for sale that are properly cleaned and repaired.

2. Tanks without heating or cooling functions for non-hazardous materials.

3. Materials to repair and replace existing ISO tanks.

Consider used ISO tanks for sale to save money

Many manufacturers buy used ISO tanks as well as new ones. A used tank can save you a lot of money. And if the used tank comes directly form a manufacturer, it will be thoroughly inspected, cleaned and repaired before you purchase it. Used tanks range in price from $10,000 to $15,000, depending on their size and the function. For $10,000, you can get a 20,000- to 30,000-gallon food grade model. Stainless steel tanks with refrigeration or heating capabilities are more expensive.

I recommend: Central Valley Tank of California offers new, used and custom ISO tanks for a variety of hazardous and non-hazardous materials. It will quote you a price on request. Quantum Tanks sells new and used ISO tanks available in as-is condition or refurbished.

Buy ISO tanks made to hold water or foodstuffs

ISO tanks for holding and transporting food are available through manufacturers. These tanks have a protective liner to prevent food or water contamination, and can also be fitted with heating and cooling capabilities. Non-hazardous ISO tanks cost $12,000 to $16,000 depending on their size, which can range from 3,000 to 20,000 gallons.

I recommend: ISOTanks WorldWide sells a variety of tanks that transport non-hazardous materials, including food and water. Dana Companies has equipment sales and leasing for a variety of food grade ISO tanks, with prices and leasing credit upon request.

Invest in an ISO tank for sale specified for hazardous materials

An ISO tank for hazardous materials is a safe, often necessary way to transport and store liquids and gases classified as hazarous materials. ISO tanks specifically for hazardous materials have special linings, heating or cooling capacity, and reinforced steel on the outside. A tank with all these specifications will cost $23,000 to $25,000, depending on the tank's capacity.

I recommend: General Industries offers ISO tanks with features for hazardous materials, including double-walled tanks and tanks with a flame shield. You can request a quote for all types of these tanks. Greensville Transport offers ISO tanks for a variety of hazardous materials, and offers transportation services for most sizes of ISO tanks.

ISO tanks are storage containers that meet International Shipping Organization regulations. Originally designed for marine shipping, they are tough and strong enough to withstand harsh temperatures and environments. ISO tanks were initially used primarily for shipping, but more recently have been used as back-up hot sites and telecommunication shelters.

ISO tank manufacturers sell heated ISO containers as well as custom ISO containers if your business has special needs that won't be met by international standards organization tanks. If you are considering obtaining ISO tanks, you will need to answer the following questions:

1. Heated ISO tanks or refrigerated ISO tanks?

2. Buy or rent your ISO tank?

3. Modified ISO containers or standard ISO containers?

Buy used ISO tanks

Many companies buy their ISO tanks used. Used industrial equipment must be fully inspected prior to purchase since many are sold 'as is,' which means if there is a problem that isn't detected until later, then it becomes your problem. Still, if you do your homework when looking at ISO tanks for sale, buying used ISO tanks can save you a lot of money compared to purchasing new.

I recommend: Central Valley Tank of California and Tank Service sell used ISO tanks. Network International is a broker for selling used equipment, including ISO tanks, through auctions and private sales.

Rent your ISO tank

Companies often choose to rent or lease their ISO tanks, especially if their tank needs are just temporary. Depending upon how often your business needs to transport goods, it may well make fiscal sense to rent rather than buy. You can lease one ISO tank, or an entire fleet, at a fraction of the price it would take to buy.

I recommend: GE Sea inspects all leased ISO tanks and guarantees the tanks are expertly maintained and tested. PriceWise Containers ensures that all tanks are in wind- and water-tight condition so you can feel confident in the equipment that you're renting.

Buy modified ISO containers

Standard ISO shipping containers come in 20' and 40' sizes and are made of steel or aluminum, but if you need larger or smaller sizes, ask for modifications. Containers can be outfitted with cabinet and storage systems, doors, windows, vents and electrical power supply.

I recommend: Visit Sea Box and The RCS Group to see examples of modified ISO containers. They will work with you to create a container to fit your needs and specifications. ISO Tanks Worldwide sells modified tanks as well as a selection of refrigerated tanks.

• •  Some companies will allow you to rent to own your ISO tanks. Renting allows you to see which containers work best for your needs before you make the decision to buy.

ISO tanks meet the specifications requirements set by the International Organization for Standardization for transporting freight by rail, truck and ship. Common types of ISO tanks include dry tanks, insulated or heated ISO containers, open-top and flat-rock ISO tanks.

Flat-rock ISO tanks come with collapsible end bulkheads that can be used for moving heavy machinery. These types of ISO tanks do not have side walls like the others. Open-top ISO tanks are shaped like boxes that you can load from the top or the end. Coal and grains are some items that are commonly loaded into open-top ISO containers. Insulated ISO tanks transport frozen goods, while a thermal, or heated, ISO container carries temperature-sensitive goods. Cube ISO tanks, also known as dry ISO tanks, are enclosed structures that can be front-loaded for general-purpose transportation of items. As for tank sizes, the common width for most containers is 8 feet, and length can be anywhere from 20 feet to 40 feet to 56 feet.

1. Pick ISO tanks for sale that match your business needs.

2. Look for International Organization for Standardization tanks that come in small or large sizes.

3. Browse publications and other resources related to ISO tanks types and styles.
