Customs and Duties
Travelers from the United States should experience little difficulty clearing customs at any Italian airport. It may be more difficult to clear customs when returning to the United States, where residents are normally entitled to a duty-free exemption of $800 on items accompanying them. You'll have to pay a tax (most often a flat percentage) on the value of everything beyond that limit. When you shop in Italy, keep all your receipts handy, as customs inspectors may ask to see them as well as the items you purchased.
Fresh mushrooms, truffles, and fresh fruits and vegetables are forbidden. There are restrictions on the amount of alcohol allowed in duty-free, too. Generally, you can bring in one liter of wine, beer, or other alcohol without paying a customs duty; visit the travel area of the Customs and Border Patrol Travel website for complete information.
Italy requires documentation regarding the background of many antiques and antiquities before these items are taken out of the country. Under Italian law, some antiquities found on Italian soil are considered state property, and there are other restrictions on antique artwork. Even if purchased from a business in Italy, legal ownership of artifacts may be in question if brought into the United States. Therefore, although they don't necessarily confer ownership, documents such as export permits and receipts are required when importing such items into the United States.
