Why Material Selection Matters
The material of your IBC tank determines its chemical compatibility, temperature limits, durability, weight, cost, and regulatory compliance. Selecting the wrong material can lead to container failure, product contamination, safety hazards, or unnecessary expense.
This guide covers the five main IBC material types available today. For each material, we detail the advantages, disadvantages, chemical compatibility, temperature ratings, cost ranges, service life expectations, and ideal applications. Use this information alongside the comparison table to make an informed decision for your specific use case.
If you are unsure which material is right for your application, our team can help. We have experience across every major industry and can provide recommendations based on the specific chemicals, temperatures, and regulatory requirements you are working with.

HDPE (High-Density Polyethylene)
HDPE is the most widely used material for IBC tanks, accounting for the vast majority of all IBC containers in circulation. It is lightweight, cost-effective, and resistant to a broad range of chemicals. HDPE IBCs are typically constructed as a blow-molded bottle housed inside a galvanized steel cage with a steel or plastic pallet base. This material is the go-to choice for food and beverage, agricultural, and general industrial applications.

This design combines the chemical resistance of HDPE with the structural protection and stackability of a steel frame. The vast majority of IBC tanks on the market are composite type, making this the most universally available and compatible configuration.

How to Choose the Right Material
Follow these steps to narrow down the best IBC material for your application.
Identify Your Stored Product
Start with the chemical or product you plan to store. Check its Safety Data Sheet (SDS) for material compatibility recommendations. If the SDS specifies HDPE or stainless steel, that narrows your options immediately. For food products, ensure the container material is FDA-approved for food contact.
Determine Temperature Requirements
Will the product be stored at ambient temperature, or does it need to be heated, cooled, or maintained at a specific range? HDPE and composite max out at around 140F. Stainless steel handles extreme heat and cold. Carbon steel is a middle ground. If your product needs heating, stainless steel is often the best choice.
Check Regulatory Requirements
Food-grade, pharmaceutical, or hazardous material applications often have specific container material requirements. FDA, cGMP, UN/DOT, and OSHA regulations may dictate your choice. Pharmaceutical manufacturing almost always requires stainless steel with validated cleaning procedures.
Evaluate Your Budget
HDPE and composite are the most affordable. Stainless steel is a significant investment but lasts much longer. Consider total cost of ownership, including the number of reuse cycles, maintenance costs, and eventual disposal. A stainless steel IBC that lasts 20+ years may be more economical long-term than replacing HDPE every 5-7 years.
Consider the Full Lifecycle
Think about how the tank will be filled, transported, stored, dispensed from, and cleaned. Some materials are easier to clean, more forgiving during transport, or simpler to dispose of at end of life. Also consider whether used or reconditioned options are available and appropriate for your application.

Frequently Asked Questions
What is the most common IBC tank material?
HDPE composite (HDPE bottle in a steel cage) is by far the most common, accounting for the vast majority of all IBC tanks in circulation. This configuration is the industry standard for food, beverage, agricultural, and general industrial applications.
When should I choose stainless steel over HDPE?
Choose stainless steel when you need high-temperature capability (above 140F), solvent compatibility, pressure rating, autoclavability, or when regulatory requirements (such as cGMP for pharmaceuticals) mandate stainless steel. Also consider stainless when you need a very long service life (20+ years) to offset the higher upfront cost.
What is the difference between 304 and 316L stainless steel?
316L contains molybdenum which gives it superior resistance to pitting corrosion from chlorides and marine environments. The 'L' designation means low carbon, which prevents sensitization during welding. 316L is the premium choice for pharmaceutical, biotech, and aggressive chemical applications. For most other uses, 304 is perfectly adequate and more affordable.
Can I store solvents in an HDPE IBC tank?
It depends on the solvent. HDPE is compatible with many aqueous solutions, alcohols, and some organic chemicals. However, aromatic solvents (toluene, xylene), chlorinated solvents (methylene chloride), and ketones (acetone, MEK) can attack HDPE, causing swelling, softening, or failure. For these solvents, stainless steel is the appropriate choice.
Are carbon steel IBCs common?
Carbon steel IBCs are less common than HDPE or stainless steel but serve an important niche for petroleum products, lubricants, hydraulic fluids, and other non-corrosive industrial liquids. They are also used for high-temperature applications where HDPE would fail and stainless steel is not justified by the chemical requirements.
Can I use a reconditioned IBC for food products?
Yes, provided the tank is food-grade and has been properly cleaned to FDA standards. Reconditioned HDPE and composite IBCs with documented food-grade history are suitable for food contact applications. For the highest level of assurance, new virgin HDPE or stainless steel containers are recommended.
How do I check chemical compatibility for my specific product?
Start with the chemical's Safety Data Sheet (SDS), which often includes container material recommendations. You can also consult our chemical compatibility information on this page, or contact us at info@ibcsantaana.com with the specific chemical name, concentration, and temperature, and we will provide a compatibility assessment.
Do you carry all material types?
Yes. We stock HDPE composite tanks in both new and reconditioned. Stainless steel (304 and 316L) is available new with short lead times. Carbon steel tanks are available by special order. Contact us to discuss availability and pricing for any material type.
Important Disclaimers
The chemical compatibility information on this page is provided as general guidance only. Actual compatibility depends on chemical concentration, temperature, duration of contact, and other factors specific to your application.

Temperature ranges listed are for continuous exposure. Short-term exposure limits may be higher. Consult manufacturer specifications for exact ratings on specific tank models.
Pricing ranges are approximate and vary based on size, configuration, supplier, and market conditions. Contact us at info@ibcsantaana.com for current pricing on any material type.
Service life estimates assume proper use, storage, and maintenance. Actual service life may be shorter or longer depending on the specific application, stored chemicals, UV exposure, and physical handling conditions.
