Wow, this one was actually a tough one to figure out... Now, there is no set answer I can offer you, but here goes it!!!
What is the allowance for alcoholic beverages brought into the United States?
Adults may bring in, free of duty and internal revenue tax, not more than one liter of alcoholic beverages - beer, wine, liquor - for personal use. Quantities above the one-liter limitation are subject to duty and internal revenue tax.
--> Of course, you know that you are allowed 1L. However, they must be satisfied that your importation is for PERSONAL USE ONLY; otherwise, it can get complicated.
--> Each state has its own rules regarding importation of alcohol into the State, which are usually 'more restrictive' than federal liquor laws.
--> These are some sample rates, according to CBP:
DUTY AND TAX RATES SAMPLES (Approximate):
Beer - 15 cents per liter
Still Wine - 34 cents per liter
86 Proof Scotch - $3.06 per liter
--> My suggestion would be to contact CBP or maybe even ATF (they are responsible for setting these laws) and ask the rates regarding importation into your specific state.
Sorry that I can't help further. I'm not American so I don't know these laws extremely well, but best of luck. Heck, $95 for Blue Label is a great deal!
