Deep Dive
One‑Trip
What it is — A container used once for export and then resold. Expect clean interiors, straight walls, and minimal wear. Why choose it — Best for conversions, retail displays, and long‑term storage where appearance and lifespan matter.
Cargo Worthy
What it is — Inspected and certified with a valid CSC plate for international shipping. Why choose it — Required for export and ideal when verified structural integrity is essential.
Wind and Water Tight
What it is — Guaranteed leak‑free with functioning doors but not automatically certified for shipping. Why choose it — Best value for secure on‑site storage and low‑cost conversions where export paperwork is not needed.
As‑Is
What it is — Sold without guarantees. The buyer assumes all repair and safety risk. Why choose it — Useful for salvage, parts, or projects when price is the overriding factor, but expect unknown repair costs.
Key Decision Guide
- Shipping internationally — Choose Cargo Worthy or One‑Trip with a CSC plate.
- Best appearance and longevity — Choose One‑Trip.
- Budget storage only — WWT is usually the sweet spot.

Risks, Red Flags, and Practical Tips
Mislabeling — Some sellers market WWT or As‑Is units as cargo worthy without documentation. Always verify the CSC plate and inspection records.
- Hidden costs — As‑Is units can hide floor rot, structural corrosion, or door seal failure. Budget for inspection and repairs.
- Transport and siting — Repairs and modifications increase delivery and placement costs. Get full delivery quotes that include site access and rigging.
- Inspection action — Request photos of the CSC plate, interior floor, door seals, and roof. Inspect in person or hire a local surveyor when possible.
