US Citizen Duty & Customs

Exemptions

To sum it up for everyone, since our cruise stops at a U.S. insular 
possession (St.Thomas) US Citizens can bring back $1600 worth of duty free 
merchandise per person, AS LONG AS no more than $800 is from 
a NON U.S. insular possession.

You may bring back 1000 cigarettes as part of that $1600, 
AS LONG AS at least 800 of them are bought in a U.S. insular 
possession (St. Thomas).

Finally, you may bring back 5 liters of alcohol duty free, 
AS LONG AS at least 1 of them is from a U.S. insular possession 
(St. Thomas).
