. In the import export business, time is one of the most important factors to consider. In importing products, the delivery process starts as soon as you buy the product and bring it to your warehouse or store. The time spent for these operations should be considered critically in order to avoid delays and extra expenses on the handling of these products. In the same manner, in exporting products to other countries, the delivery process starts as soon as you send the products to the receiving party. The delivery process is only concluded when the receiving party receives the products. Thus, any delay in the delivery process would mean extra handling expenses.
