I am shipping them in our HAZMAT tricon.
Excellent. It's good that they've provided you with a way to get them there.
Have fun in the heat -- I worked at FLIR Systems up to the early 2000's, where Saudi runways taught us some lessons in thermal management. It can get brutal, particularly when your equipment is painted black, and hanging off the bottom of a helicopter, right over black pavement, in the middle of the day. Thankfully it was a mostly a spectator sport for me -- I was designing software and systems architectures. It was the mechanical guys who got to take the brunt of the effort -- I just got to make suggestions about how to make boards use less power, or justify why they couldn't.
