How are the shipping containers delivered?

Interport shipping containers are delivered by truck, either tilt-bed or flatbed. A tilt-bed truck allows the container to be positioned on the ground at the delivery location. Delivery by flatbed truck generally costs less than by tilt-bed, but requires that you have the proper machinery to lift the shipping container off the truck at your site. For container purchases, Interport can arrange delivery through one of its third-party trucking providers or you can engage the trucking company of your choice to pick your container up at Interport’s depot. 

How should I prepare the ground for delivery?

Your shipping container should be placed on firm, dry, level ground, i.e. pavement, gravel, or hard dirt.

How much room is required for tilt-bed delivery?

For a 20-foot container: 60’ of straight running room; for a 40-foot container: 110’ of straight running room.

How can my shipping container be customized?

Interport can add personnel doors, roll-up doors, or windows, and can paint your container. Other container customization options are also available.

How is payment made?

Once you’ve ordered your shipping container, Interport will issue you an invoice. Once your invoice is paid via check, money order, wire transfer, cash, or credit card, Interport will release your container to you or to the trucking company making your delivery.
