How often do propane tanks need to be recertified

All propane cylinders must be recertified every 10 years. Dates can be verified on new cylinders by checking for a manufacturers 4 digit month/year stamped on the collar. Cylinders that have previously been recertified will have an aftermarket 6 or 8 alphanumeric stamp that will read like the following example: 02X07E or 07ABC07E. The first two digits are the month followed by the certification code followed by two digits representing the year. Once the 10 year cycle has passed, it is not legal to refill the cylinder until it has been inspected and certified.
