The amount of your duty-free exemption depends on the country you are returning from. In most cases, each individual is allowed to bring back $400 worth of goods without being required to pay duty. Family members traveling together and living in the same home may combine their personal exemptions by filing a joint declaration. These exemptions apply if:
If you are returning directly from certain Caribbean Basin countries your customs exemption will be $600 and if you return directly or indirectly from the U.S Virgin Islands, American Samoa or Guam, you are allowed a $1200 exemption. If traveling to one of the countries mentioned above, you may wish to check in with your nearest Customs office for specific details.
