When returning to the United States, each individual must complete the CBP Declaration Form 6059B. This form requires travelers to itemize all purchased merchandise and declare any other items they are bringing into the country, including gifts, items for personal or household use, and items intended for sale or use in a business. Travelers must declare all items they purchased and are carrying with them upon return to the United States, including duty-free items purchased in foreign countries. To avoid confusion, travelers may want to register certain items with U.S. Customs before leaving the United States, particularly expensive foreign-made items like laptops or watches.
