A collaborated group met the similar situation with FedEx before and they switched to World courier afterwards. When your shipping dewar is no longer leaking of course, maybe you would like to check out the following link below. According to our users, crystals stored in the CombiPuck seem to get less or no ice up after shipment, possibly because the vials inside the puck helped keep the LN2 temp well. The 16pins puck base format of the CombiPuck is the same format as the UniPuck. It is easy to switch from crystals stored in canes or any other formats of the pucks to the CombiPuck. It is also easy to retrieve the crystals from the CombiPuck back to the canes or any other pucks when needed. https://www.mitegen.com/product/combipuck-system/

That only explains everything we have seen with completely damaged samples, lost, flying around the dewar etc ...

I sent it to a company that specializes in repair and refurbishing of cryogenic tanks, and they told me it has an internal leak, and hence is not reparable. I was expecting that the valve had failed, so the internal leak diagnosis came as a surprise. Has anyone else had a similar experience? Any ideas about how an internal leak might come about? The dewar is (was) a Taylor/Wharton CX100, and it was traveling in its bespoke shipping case. Thanks for any insights that might satisfy my curiosity and/or prevent future mishaps of this sort.
