Custom ISO Tank

Tank Guru Q&A: How Old is Too Old?

Question: This question applies to regulations which specify the age of ISO tank containers. “My company wants to send a hazardous cargo (toxic & corrosive liquid) to the USA. Currently we are using old IMO1 (US DOT) tank containers for non-USA destinations.

  1. In specific reference to the USA, are there any regulations (US DOT or otherwise) that specify the age of ISO tank containers beyond which the tanks are not allowed to enter the USA?
  2. In general reference, for how many years a portable tank container can be kept in service for our type of cargo?”

Tank Guru:

There are no regulations that specify the age of tank containers.  And when properly maintained, tank containers can last indefinitely.

We have refurbished tanks that were built in the 1960s and they were as good as new once complete.  But we have also seen brand new tanks which were completely destroyed because of corrosive products.  It has everything to do with how well you maintain your equipment.  If you transport a product that is corrosive to stainless steel, then obviously the tank and its valves need to need to be lined.  Regular inspections should be carried out to ensure that the lining is not compromised.
