CW and WWT containers are similar in many ways. Both have experienced extensive use in maritime shipping service and are typically 5-10 years old. However, these two container types are actually of different quality grades, with Cargo Worthy containers being a Grade B, and WWT containers being a Grade C.
While both types typically have a substantial amount of dents, rust, scuffs and visible usage, WWT containers generally have a greater degree of usage and age markers with extensive rust, wear-and-tear of floors and doors, and previous repairs common by the time of resale.
Cargo-Worthy containers may also have a longer lifespan due to their considerably better condition. Of course, there may also be a significant price difference between the two for the same reason. While Cargo-Worthy containers are ready to be certified for international shipping service, WWT containers may require additional repairs before receiving certifications, while this is not always the case. Choosing between a Cargo-Worthy and a WWT container typically comes down to the budget, usage plans and longevity goals of the buyer.
