Different laws exist for small propane tanks — such as those used for gas grills and portable stoves — and for larger tanks used to heat a home or other building. Adding to the confusion, some states have passed laws that differ from the federal mandate. In this post, we’ll attempt to shed some light on the situation.

How Long Are Small Propane Tanks Good For?

Propane tanks of 100 pounds capacity or less have an expiration date of 12 years from the date of manufacture. Once those 12 years are up, you can either exchange the tank for a replacement, or have it inspected for requalification for an additional five years of use. 

How Long Are  Home Propane Tanks Good For?

In most states, large propane tanks used for home heat and hot water are governed by federal container laws. These laws dictates that a propane tank can only be filled by its owner or someone authorized to act for them. In practice, this means most home propane users lease their tank from a fuel supplier, who assumes responsibility for keeping track of its expiry date.

Federal container laws, as well as other regulations governing smaller propane tank expiry dates, have been endorsed by leading industry groups such as the National Propane Gas Association. Given the specialized nature of propane fuel and the need for well-maintained, reliable tanks, these laws help enforce a standard of safety that protects all users.
