I did a search using Ask Jeeves and one of the sites said this....
"U.S. Customs codes state "The importation of Absinthe and any
other liquors or liqueurs that contain an excess of artemisia
absinthium is prohibited."
In real world practice it is illegal to import any liquor that contains
a detectable concentration of artemisia absinthium.
U.S. Customs can seize anything labeled as absinthe. If they do
or don't, that depends on the knowledge and discretion of the
agent.
If absinthe does not contain artemisia absinthium, and there are
several brands available, the product is fully legal in the US. Most
companies that sell non artemisia absinthium absinthe guarantee
no U.S. customs problems."
(sorry don't know the real link cos of how ask jeeves works)
anyway, it depends whether it actually has artemisia absinthium (wormwood) in it. if it doesn't it's legal, but it's not worth getting, it'll just be like 4x strength vodka or something.
your poor thing being in the US... it's all perfectly legal here in the UK - i've got a bottle in my cupboard!
