The Main Categories of Shipping Container Conditions

Conditions of Different Conex Boxes / Sea Cans

Understanding the quality or shipping conditions of the container you are looking to purchase. Is quite important when trying to determine how it is going to be used. For example, a used lower grade container with rust & dents. May seem like a more affordable option, when using it for temporary storage. However, when building a prefab home or a temporary working space. There are many safety considerations to keep in mind.

Some of those considerations include; how many trips has the container made, what potential harmless consumer goods, or hazardous industrial materials may have been transported inside, is there rust or dents on the top of the container? etc. For those reasons, purchasing a new (one trip) container for a home or temporary working space, might be a better idea instead.

Below you will identify some of the more recognized industry standard container conditions you will find in the market today. This should give you a better idea, about what type of container will be most suited for your next project or task:

New (One Trip) Shipping Containers

One trip shipping containers are typically exactly what the name suggests. They are units that have withstood one shipment overseas carrying cargo, that are now ready for sale or for rent. Out of all the conditions, the “One Trip” is recognized as being one of the most popular and in demand. ⁽¹⁾

Although not really brand new. They are considered “As-New” and are pretty much some of the highest quality you will find (with some slight wear and tear from transport), when deciding to purchase. Excellent for use as storage, cargo transport or for anyone looking to build a prefab home, office, restaurant, tool shed etc.

Cargo Worthy (CW/CWO)

Cargo Worthy containers are units that abide by the the shipping industry ISO standards. This simply means that the container has been inspected by a quality professional inspector within the last year. These containers are considered to be very strong, durable and weather resistant enough to board a cargo container ship. While remaining high quality, these units usually show more wear and tear than New (One-Trip) containers.

Cargo Worthy boxes are suitable for most purposes such as; storage, cargo transport or building a prefab home, office or retail space (depending on the physical aesthetics and overall use). This is mostly due to their floors generally being in good condition. ⁽²⁾

Despite being durable enough to transport cargo. One thing to mention. Is that a Cargo Worthy container, does not necessarily have the valid CSC plates or documentation to be shipped overseas. If at any point you do plan on shipping your conex box overseas. You will be required to have an updated CSC survey completed beforehand.

Wind & Watertight Containers (WWT)

Generally, containers that are categorized as Wind & Watertight. Are meant for storage as opposed to cargo transport. As the name states, they are secure enough to protect from elements such as water and wind. Essentially there should be no holes, so you should be safe from leaks.

These containers have age and are usually somewhere around 10 years old or more. In many cases you will identify dents, scratches and rust along the exterior of the unit. If you’re looking for a cost-effective solution that can still secure your storage, for the short-term or the long-term. This might be one of your best options. WWT units can also work for those looking to modify or convert a project. ⁽³⁾

*Unlike Cargo Worthy containers. Wind & Watertight units do not need any formal inspection by a professional inspector or organization.

*CW & WWT containers can sometimes look similar from the exterior. However, Wind & Watertight containers are only suitable for cargo storage and not cargo transport.

Institute of International Container Lessors (IICL)

The IICL uses a review and grading process, to certify that used containers under their review system are in good condition. These used containers are roughly one step down from a new One Trip container, in terms of quality. Despite being used, these units usually don’t show many exterior markings. Not only are these units great for storage, but they can also be used to transport cargo as well. ^{(4, 5)}

As-Is Shipping Containers

These containers are pretty much how they sound. As they are. These units have no guarantee on their quality or overall functionality. These are the units that you can almost expect to identify rust, dents, holes etc. As-Is-Containers are probably some of the most affordable you will find on the market. However, without some form of maintenance. They are also some of the more unreliable / risky to work with.

If you’re willing to put in time or pay for the maintenance work. You just may be able to repair some of the damages undertaken by the container over the years. However, understand that it’s probably best suited for storage as opposed to cargo transport. Even after repairs. ⁽⁶⁾

CW / WWT Similarities & Differences

While being two of the more common conditions you will identify in the container market. Besides both having visible exterior damage and rust. There are some notable differences that you should be aware of, when deciding which type will work best for your needs. Some of those differences include but aren’t limited to;

Cargo worthy containers are usually a little more expensive than wind and watertight.
Though wind and water resistant. Wind & Watertight containers usually are not certified.
Cargo worthy containers are recognized as durable and secure enough to ship items.

One thing to mention, is that shipping container condition doesn’t always detail everything you need to know. The conditions mentioned above are great starting points. However, if you can. Schedule a visit or try to obtain photos. In most cases this is not feasible. Mainly due to demand and state of the supply chain. ⁽⁷⁾

*Many companies have guarantees about their containers and will offer money back if those parameters aren’t met. It varies from company to company, so it’s a good idea to inquire in advance, before placing an order and setting up delivery.

*You may notice grade levels associated to some containers. Keep in mind that these grade levels are not measured by any particular standard and can vary from each supplier.

Closing Thoughts

At the end of the day. Choosing the right container classification or condition. Comes down to your intent, personal preference, along with what you have available in your budget. It’s good to understand these conditions in advance. As it enables you to get a better idea of what projects or tasks are feasible, with the container condition you have selected.

For example, an “As-Is” shipping container may be well suited for storing furniture, or any unused items that you have in your possession. Although, due to the number of years it has been in use. Along with exterior dents, rust or other markings (eg. scratches or grafitti). It may not be the best solution when looking to put together a container home or office.

Whatever you’re intended use, we recommend not choosing a container just because it may be low priced. Especially if you plan to use it for more than temporary storage. Similar to purchasing a used vehicle. The last thing you want to do is purchase cheap. Only to find out that you have expensive recurring maintenance costs, that you weren’t prepared for after purchasing. A lower price doesn’t necessarily mean good quality. Although quality is one of the key aspects to look for when purchasing a shipping container. Especially for long term storage, reliable cargo transport, residential, commercial or industrial use.
