Container ports are one of the most important parts of the supply chain. Due to high investment and operating costs, the structure and predictability of current and future demands are very important. To investigate this structure, this study aims to determine whether the shocks to the export and import container quantities handled in Turkish ports are temporary or permanent. Both standard unit root tests and unit root tests with structural breaks were applied to export and import container amounts. According to the results, when the structural breaks are considered, it has been determined that both export and import container quantities are stationary. This situation shows that the effects of the shocks to the container traffic are temporary, the applied policies lose their effect in a short time and the future container traffic can be predicted using historical data.
