The Difference Between Wind & Watertight Containers vs Cargo Worthy Containers

The Difference Between Wind & Watertight Containers vs Cargo Worthy Containers

When shopping for used shipping containers, sometimes the difference in container conditions is not as obvious as you would think. On the surface, Wind and Watertight (WWT) and Cargo Worthy (CW) containers are both used and have rust, dents, scratches, etc. Visually, a wind & watertight container can look just like a cargo worthy container. Here’s a little more information about the specifics of each condition, to help you determine which option works best for you.

Cargo Worthy:

These containers are mainly used for shipping overseas. In order to ship a container overseas, it typically requires an inspection from a marine/maritime surveyor. The surveyor will ensure that the unit meets the CSC (International Convention for Safe Containers) requirements for shipping. The owner of the container will be issued a certificate, stating that the unit is seaworthy or Cargo Worthy. This document is required by the port authority, prior to the unit being loaded on a vessel and shipped. Containers are stacked on a vessel for transport. They need to maintain certain structural standards, as to not compromise the integrity of the other containers in the stacks. You can expect the containers to range in age from 10-15 years old.

Wind and Watertight:

WWT containers are also guaranteed not to leak or have holes. However, they might have some patches or repairs, due to some damage that was sustained in shipping. These storage containers cannot be shipped overseas, as they do not meet the requirements of the CSC (referenced above). That does not mean they’re not adequate for general storage purposes. Most folks looking to store items on-site would go with this option. Your container doesn’t need to be Cargo Worthy if you’re not going to ship it overseas. A WWT container will usually cost a bit less as well, since they don’t need to be surveyed. They are simply inspected by the yard, to ensure they meet the requirements to be called WWT. These containers will also range in age from 10-15 years old.
