Grade A (IICL5)
These are the highest grade within the shipping industry for used containers. They are of high enough quality that they are still certified to be used in the shipping industry. They will have minimal rust and dents, be wind and water tight, and will have doors/floors/seals still in great condition.

Grade B (CW)
Similar to our grade A containers in that they are still certified to be used in the shipping industry. They have no defects or major damage to the structural integrity of the container. These are superior shape cosmetically to our grade C or grade D containers, and will cost less than a grade A container, making it a great option for a used container.

Grade C (WWT)
These are the most common container on the market, and are the cheapest option if you are looking for a container that is guaranteed to be weather proof and rodent proof. These containers are between 10-15 years old and have been retired by the shipping line so they can show considerable wear and tear. If you are on a tight budget and do not care as much about the cosmetics of the container this may be the best option for you.

Grade D (As Is)
These have been damaged in one way or another and are sold “as is”. These containers have been taken out of commission in the shipping industry and are not suitable for storage. They could have majority damage on the roof or walls, damaged floors, bad seals, doors that are difficult to open, or structural damage.

Acronyms / Keys:

 CWCargo Worthy – Criterion under which a used shipping container is deemed suitable for the transport of cargo under TIR / UIC / CSC, and meets all the standards laid out in its original specification. The CW Cargo worthy standard generally implies that the container has a valid CSC. Cargo Worthiness can be certified by a third party container surveyor pursuant to a physical inspection of the used shipping container.

 WWTWind & Water Tight – a criterion under which containers are literally “wind and water tight”. In short, if you lock yourself inside the container, you should not see any light coming through the panels or roof. It should be noted that this criterion however makes no reference to the quality of the understructure. A WWT container should therefore not be considered safe for the transport of cargo; unless it is explicitly confirmed it meets the CSC. WWT is commonly used to describe and qualify used storage containers. WWT + CSC = CW !

 IICLInstitute of International Container Lessors – an organization which groups the largest container and chassis leasing companies worldwide. The IICL sets repair standards, by which all repairs are carried out, for its members when containers are off hired. IICL is the strictest criterion out there for used containers.

CSCConvention for Safe Containers – established in 1972 to promote and maintain a high level of safety of human life in the transport and handling of containers by providing generally acceptable test procedures and related strength requirements. This has helped facilitate the international transport of containers by providing uniform international safety regulations.

ISOInternational Standardization Organization – International organization based in Geneva working towards harmonizing worldwide technical standards; including those governing the construction of shipping containers.
