Its customers are electronics companies in the United States, including computer manufacturers and audior' visual product manufacturers. The company contracts to purchase components and parts from manufacturers in Istanbul, Turkey and it has them delivered to warehouses in three European ports, Gdansk, Hamburg, and Lisbon.

From me inland ports, the containers are transported to PoyrarTech's distribution centers in Fargo, Fort Wayne, Denver, Tucson, and Cleveland.
