How Often Does an IBC Tank Need Inspection?

An IBC tank that will hold liquids needs to be inspected every 2.5 years to ensure it is durable and still meets shipping/transport requirements. However, an internal IBC test is required every five years for durability. IBC tanks will also need to undergo other small inspections periodically. 

What is Looked at During Inspection

Numerous aspects are looked at during inspection. This includes checking the interior for leaks, that it can work with service equipment, and that it follows DOT requirements. Other aspects that will be looked at include ensuring the materials are not cracked or warped, all valves are plugged, and that the walls of the IBC meet the correct thickness measurement. Some will also need to undergo internal pressure testing. 

After being inspected, the tank is then marked with the date of inspection and is attached with a record of retention that states what was tested. This record will usually be engraved into the tank’s plate to ensure that the records are not lost. This also helps the tank to quickly move through inspections when being shipped to a new building.  

When an IBC Tank Does Not Pass Inspection

If an IBC tank does not pass its inspection it will either need to be discarded or repaired to meet the requirements. If the tank is repaired, it must follow its original design and pass both internal and external tests. If the tank still does not meet inspection requirements, it will be fully rejected from future inspections.
