A Carnet or ATA Carnet is an international customs and temporary export-import document that allows for temporary entry of goods on a duty-free and tax-free basis, whether shipped or hand-carried. It is often referred to as the "Passport for goods". The ATA Carnet system was established by the International ATA Conventions and is governed by the World Customs Organization and the International Chamber of Commerce’s World Chambers Federation.
The ATA Carnet allows the business traveler to use a single document for clearing certain categories of goods through customs in several countries without the deposit of import duties and taxes. The Carnet eliminates the need to purchase temporary import bonds. So long as the goods are re-exported within the allotted time frame, no duties or taxes are due. ATA Carnets cover most goods or merchandise, including commercial samples, professional equipment, and goods intended for use at trade shows and exhibitions. However, ATA Carnet is not recommended for goods intended for sale.
ATA Carnets are issued by chambers of commerce and are valid for up to one year. They cover the usual and unusual items such as computers, repair tools, photographic and film equipment, musical instruments, industrial machinery, etc.. A duplicate Carnet is issued to replace an existing Carnet in the case of the destruction, loss, or theft. The validity of which expires on the same date as that of the one being replaced. Some countries also accept replacement carnets.
