I have succesfully mailed frozen stocks from Boston
to Switzerland in dry ice. (I took it to the airport myself
and had someone pick it up when the plane arrived).
Just make sure that the samples are packed well within dry ice,
and make sure you have enough dry ice for the trip so that
they remain frozen.
