The ATA Carnet, often referred to as the "Passport for goods", is an international customs document that permits the tax-free and duty-free temporary export and import of nonperishable goods for up to one year. It consists of unified customs declaration forms which are prepared ready to use at every border crossing point. It is a globally accepted guarantee for customs duties and taxes which can replace the security deposit required by each customs authority. It can be used in multiple countries in multiple trips up to its one-year validity. The acronym ATA is a combination of French and English terms "Admission Temporaire/Temporary Admission". The ATA carnet is now the document most widely used by the business community for international operations involving temporary admission of goods.

Customs is an authority or agency in a country responsible for collecting tariffs and for controlling the flow of goods, including animals, transports, personal effects, and hazardous items, into and out of a country. Traditionally, customs has been considered as the fiscal subject that charges customs duties and other taxes on import and export. In recent decades, the views on the functions of customs have considerably expanded and now covers three basic issues: taxation, security, and trade facilitation.
