What is a Surveyed and Certified Container?

Containers must be inspected regularly if they are to be used for international, maritime transportation.  New containers are given a 5-year grace period.  After this grace period they must be inspected by a certified professional, who can validate a container for up to two years.  The purpose of the inspection is to maintain a high level of safety of human life in the transport and handling of containers, and to facilitate the international transport of containers by providing uniform international safety regulations.  You can learn more here.

Delivery, Warranty & General Questions

What is a New Shipping Container and what is considered a Used Shipping Container?

New Shipping Containers are manufactured in China.  They make a loaded trip to North America, which is why New Containers are often referred to as “One-Trippers.”  Used Shipping Containers come about for a variety of reasons, but by far the most common are due to more goods arriving North America than leaving, and Leasing Companies deciding to sell some of their older containers to make room for new containers.

How will my shipping container be transported and delivered?

You can choose whether you take care of the transportation of the shipping container yourself or you prefer us to deliver or pick up the shipping container for you.

If you decide to pick it up yourself:

We can load in onto your trailer at the shipping container yard. We have container loading machines that can put the shipping container on your trailer and there is no charge for this.

If we are taking care of the transportation for you:

the delivery and pick-up transportation costs will be charged according to the distance to the destination location, the type of truck used and the number of shipping containers delivered in the same run. If we can deliver the container(s) at the carrier’s convenience, he may be able to match up your order with another one to the same area, reducing your delivery rate.

The shipping containers will typically be delivered with a tilt-deck (in Alberta area) or a crane truck (in British Columbia) that will place the container on the ground for you at your site. Please feel free to inquire about the options available to your specific needs.

With the tilt-deck:

The trailer backs up to where you would like the shipping container placed and tilts it into the ground. The truck driver will need 13’ of clearance.

When we use a 40’-long deck, it can ship 2×20’, 1×40’, 4×10’ or any combination that makes 40′ length.


With a hiab crane truck:

The crane pulls up the container from the truck deck and places it on the ground, normally along side the truck. The trucker will need about 20′ to 30′  from the side of the truck or cleared space.

Warranty – What if I am not happy with the shipping container that I receive?

If the shipping container arrives with any damage that had not been cleared in advance, if the shipping container does not fit your space, if you changed your mind for any reason, please give us a call so that we can propose a solution for you.
