It's not a question of customs. It's a question of security. If your 2nd flight is from the same terminal then you do not have to go out of and then back through security. If you fly into terminal A then out of terminal B or C, for example, you will go out of then back through customs.
If you are flying with the same airline for both legs, this should not be a problem.
you will have to pack them into luggage
Alitalia and Delta are both part of skyteam and codeshare, in theory your luggage should be put straight through, Alitalia flies into terminal b and delta flies out of terminal b
Now, US customs works that everyone goes through customs at the port of entry so you would have to get your bags and you would have to recheck them and you would have to go through security again, and even if you dont have to go thru customs you would still go thru a security check where they take away ALL liquids INCLUDING duty free wrapped stuff
why?? cause they can........
