Which container is right for me?

Updated: Jun 24, 2022

At Superior Containers, we love helping our customers find the storage solution that meets their needs. Shipping containers come in a few different sizes, and different grades as well. Here is a handy guide to help you understand the difference between containers, and decide which one is right for you!

1. Wind and Water Tight

The WWT (wind and water tight) are your standard used shipping containers. They have been used by the shipper for 8-10+ years before they make their way to us. These boxes are no longer suitable for shipping and will not have a valid CSC plate on their exterior. However, just because a container has been retired from its shipping days does not mean that it would not be excellent for storage! WWT are our top selling boxes.

We readily carry wind and water tight in the following sizes:

20' Standard: 20' long x 8' wide x 8'6" tall

40' Standard: 40' long x 8' wide x 8'6" tall

40' High Cube: 40' long x 8' wide x 9'6" tall

These containers are used and will not be pretty- expect dings and rust on the exterior, but we do check them over to make sure there are not holes, the floors are intact, and they have working doors. Most containers have doors on one end only. Double door containers can be sourced, but are often found in one-trip condition (see below). If you're concerned about appearances, we can paint your container for an additional charge- you just pick the paint swatch color!

2. Cargo Worthy

Cargo worthy containers are a step above the WWT and have been deemed still worthy of sea travel. Containers receive their grade from a certified marine surveyor. The grades were created to categorize containers based on their sea worthiness and create consistency and safety in sea travel as governed by the ISO (International Standards Organization). If you are looking for storage for a farm, construction site, or your business, chances are your container does not need to meet ISO standards like a box that might have six others stacked on top of it and travel across the ocean. Though they are a step above in grade and typically newer, oftentimes, cargo worthy containers do not appear much different than WWT containers on the exterior.

3. One Trip/ New

"New" containers are called one-trippers because there is always that initial voyage across the sea to reach us. These containers are typically in fantastic shape with minimal dents, a nice paint job, easy open doors, and very good condition flooring. If you are interested in "nice" shipping container, a one tripper may be what you are wanting. Be prepared to spend a little more- you'll be getting a very nice product but these containers will carry a higher price tag than their used counterparts.

4. As Is

As-is containers are exactly what they sound like. They will not come with any guarantee of being water tight and typically have extensive damage from their shipping years. However, these boxes can come with a bargain price tag, so depending on your project, they could be an affordable option to consider. We do not stock As Is containers so this would be a special request for sourcing.
