Thanks pismo923.
The only reference I find at all relative to country of origin is in the Q&A section where the question is asked: "Where does this film come from?"
The response from Heather, who is on the B&H Staff, is the the film originates in the Czech Republic.
I can't comment on the NAFTA designation only to say that it would appear that the rules allow this film to be NAFTA certified since it is distributed by Freestyle, which is a business existing in one of the North American Free Trade Agreement countries. Someone with more familiarity with the NAFTA rules may be able to comment on this more completely than I.
If this isn't what you want I would cancel if the order has not shipped. If it has shipped, B&H has some relatively reasonable return policies as far as I am aware.
However, I use quite a bit of AEU400 film myself and find it very usable, particularly if you expose at EI200, YMMV
