What is ATA Carnet?


The dynamic nature of international trade requires certain standards and documents to facilitate the free flow of goods and services between different countries. One of these documents is the ATA Carnet. However, to fully understand what an ATA Carnet is and how it is used, it is important to grasp the operation of the Hiosis system, which provides this document. In this article, we will delve into what Hiosis and the ATA Carnet are, how they work, and their significance in international trade.

What is Hiosis?

Hiosis is a system developed by the Turkish Exporters Assembly (TİM) aimed at enhancing Turkey's competitiveness in international trade. Hiosis stands for "Hızlı İhracat ve Otomasyon Sistemi" which translates to "Fast Export and Automation System." This system is designed to facilitate, expedite, and minimize bureaucratic procedures in export operations. Hiosis enables the electronic issuance and tracking of various documents used in trade with other countries, allowing exporters to save time and costs.

What is an ATA Carnet?

An ATA Carnet is an international document used for temporary import and export operations. ATA, derived from the French and English abbreviations "Admission Temporaire/Temporary Admission," is a system that allows goods and equipment to enter and exit a country temporarily without payment of customs duties or other import formalities. The ATA Carnet is utilized for temporary trade purposes such as trade fairs, exhibitions, and professional equipment transportation.

Operation of Hiosis and ATA Carnet:

The Hiosis system enables the electronic issuance and tracking of documents like the ATA Carnet. An exporter applies for an ATA Carnet through Hiosis, providing details of the goods or equipment to be temporarily exported to a country. Upon application, the ATA Carnet is issued by TİM or other authorized organizations. The ATA Carnet is a document specifying the description, value, validity period, and other details of the goods or equipment to be temporarily imported or exported.

Goods or equipment marked with an ATA Carnet must be exported within the specified period and returned within the designated timeframe. Failure to export or return the goods or equipment within the specified period may result in customs duties and other penalties. The Hiosis system facilitates the tracking of this process, allowing exporters to manage ATA Carnet transactions easily.

Significance in International Trade:

Hiosis and ATA Carnet expedite the flow of international trade, contributing to its growth and development. These systems streamline exporters' operations while providing customs authorities with efficient tools for regulating and monitoring temporary import and export transactions. Additionally, documents like the ATA Carnet enable the showcasing and promotion of Turkish goods and services at international platforms such as trade fairs and events.


Hiosis and ATA Carnet are essential tools for enhancing Turkey's competitiveness in international trade and facilitating the flow of commerce. These systems expedite exporters' operations while enabling customs authorities to provide more efficient services.
