Like Thomas, I shipped my stocks across the Atlantic (Cambridge to
Dallas, in my case) on dry ice.  They were frozen in glycerol/soft
agar in the usual way.  I've used many of those tubes since -- they
survived fine.  That time I called the USDA in advance and got a
letter saying it was OK for me to take these across, had them shipped
by air, then flew over on the same plane.  I would advise, if you do
something like this, that you arrange for them to arrive in the
morning of a workday.  Mine were delayed and arrived late on a Friday,
and I had to arrange an overtime with a customs inspector to get them
out of bond.

I believe that since then the USDA ruled that C elegans can enter the
USA without special arrangements.  However, I would still give them a
call to check if it's a big shipment.  (Finding the right person to
ask may take some effort, though.)  For small shipments I figure what
they don't know won't hurt them, especially if it's something that can
easily be resent.
