The primary difference between Cargo Worthy (CWO) and Wind and Water Tight (WWT) containers lies in their ability to pass a CSC Survey for secure stacking during cargo shipment. Both types may exhibit similar wear, including surface rust and dings. Whether choosing WWT or CWO, the used shipping container's appearance will reflect typical signs of use, with WWT units potentially showing more cosmetic issues due to age. Regardless of the option, a leak-free container with sealing doors and hole-free floors is guaranteed. Pressure washing and painting can address aesthetic concerns. One Trip containers, essentially CWO units within 1-2 years of manufacture, typically have minimal cosmetic issues.
