One-Trip Containers
One-trip containers are generally newer units that have made limited cargo trips before resale. They can still have handling marks, dents or paint wear.
Wind & Watertight (WWT)
WWT is commonly used for used containers intended for stationary storage. A WWT unit is generally expected to keep normal wind and rain out when properly closed, but cosmetic wear, surface rust, patches and previous repairs can be present.
Cargo-Worthy
Cargo-worthy is commonly used for containers considered suitable for cargo transport, but transport use may require current inspection/certification and carrier acceptance. If you need to ship the unit internationally, tell the supplier rather than relying on a condition label alone.
Compare the Actual Quote
Ask whether the quote is for a representative grade or a specific unit, whether photos are available, what door/seal condition is expected, and what remedy applies if the delivered unit materially differs from the description.
