Is mail X-rayed?
Some of the mail that is sent through the United States Postal Service will pass through an X-Ray machine. There are no specific guidelines as to what may or may not be x-rayed, though mail sent to or through larger cities is likely to pass through an X-Ray machine.
Note: Marking a mailpiece "Do Not X-Ray" will not forgo the X-Raying of a mailpiece, and may result in the item being considered suspicious
If you have additional questions about X-Raying of items, contact your local Post Office.
SO - If you go by this, markig do not x-ray seems to be worse off in the end. Since they use the term x-ray I will err on the side of caution....
If/when I ever ship - I will be marking FRAGILE and that's it. I am also going to suggest any sent be marked as such also, maybe see if the results are better
