polish vodka from poland to either the USA/Canada?
Sounds like it could be difficult as you'd have to deal with the import/ export liquor laws in two lands. And in the US each state has its own Liquor Control Board (LCB) and as such the laws regulating booze vary wildly from state to state. Some liquor laws are downright archaic. Around here you can't even legally import a case of beer from a neighboring state, for crissake...
Maybe start by contacting the exporter in Poland and see what they say...
