Would be fun. If you plan to bring cigars/rum back, I believe there is a 48 stay required to use the duty free exemption. I could be wrong.
The duty-free exemptions ($200, $800, or $1,600) apply if:
- The items are for your personal or household use or intended to be given as gifts.
-They are in your possession, that is, they accompany you when you return to the United States. Items to be sent later may not be included in your $800 duty-free exemption. (Exceptions apply for goods sent from Guam or the U.S. Virgin Islands.)
- They are declared to CBP. If you do not declare something that should have been declared, you risk forfeiting it. If in doubt, declare it.
- You are returning from an overseas stay of at least 48 hours. For example, if you leave the United States at 1:30 p.m. on June 1, you would complete the 48-hour period at 1:30 p.m. on June 3. This time limit does not apply if you are returning from Mexico or from the U.S. Virgin Islands. (See also the section on the $200 exemption).
- You have not used all of your exemption allowance, or used any part of it, in the past 30 days. For example, if you go to England and bring back $150 worth of items, you must wait another 30 days before you are allowed another $800 exemption. (See the section on the $200 exemption.)
- The items are not prohibited or restricted as discussed in the section on Prohibited and Restricted Items in the "Know Before You Go" If you would like a hard copy of the publication, please order it through the Publications section of our Web site.
