There is a TravelBuzz thread http://flyertalk.com/forum/showthread.php?t=316783 related to this but I am hoping to see more TSA actuall screener response here.

Would someone with some knowledge on this, please advise me on what the procedures are for dealing with ashes coming thru security?

On the other thread, it seemed that once the initial screener okay'd it with a supervisor, that could pass thru just fine without having to open the box. (Eventually, I'll have to do this anyway, but still.) The ashes I have are 20 yrs old and, while all the cemetary and death info is on a label on the wrapping paper of the parcel-like box, I have no death cert or cremation paperwork. Hopefully, this won't be needed?
