So, I got this response back from the HR person when I asked if there was a company they preferred me to use for shipping:

"No we don't know any company would like you to use for the airfreight.
We advise you to use the cargo - door to door not express courier."

So, if I follow that advise, I will not be using Fed Ex or DHL. Anyone have any advice for me on which companies to use out of the U.S.?
