Storing DEF

As DEF is not classified as a hazardous material and has less regulations when compared to fuel storage. However, DEF’s shelf life is easily affected by temperature changes, weather exposure or dusty climates, so it’s important to securely store your DEF to ensure your stock remains pure.

Introducing our DEF Storage Containers

Storage of DEF Fluid FAQs

How should DEF be stored securely?

Due to its corrosive nature DEF must be stored in high-density Polyethylene, polypropylene or stainless steel containers. This will enhance the shelf life of your asset by keeping it away from environmental conditions such as heat and dust.

How long can def fluid be stored in a tank?

This is largely dependant on the ambient storage temperature, DEF will degrade over time depending on temperature and exposure to sunlight. As a guide, non-contaminated DEF that conforms to ISO22241 standard and stored within the optimal temperature conditions, should have a shelf life of up to 2 years.

Do DEF tanks need secondary containment?

There is not a requirement for DEF storage to need secondary containment, however it is advised in order to reduce contamination risk and the risk to the environment as DEF is corrosive and a pollutant.
