I sent a beer to New Mexico, US customs opened it up and had a look at it and that was about it. I labelled it on the customs declaration as a "Malt Soda" no lying there
and said it was a gift. I know though that Florida is harder due to state taxes. NZ is pretty easy to get stuff in the country, there main worry is agriculture and environmental risks, along with the standard drug and weapon restrictions of course.
Would be keen to do a beer swap, I think I would have no issues sending from this side.
