What are the Advantages of Using an ATA Carnet?

When using the international customs document, The Merchandise Passport, it:

• Reduces costs to the exporter. Eliminates value-added taxes (VAT), duties, and the posting of security normally required at the time of importation.
• Simplifies customs procedures. Allows a temporary exporter to use a single document for all customs transactions, make arrangements for entry to many countries in advance, and do so at a predetermined cost.
• Facilitates re-entry into the U.S. Eliminates the need to register goods with U.S. Customs at the time of departure.
