What "new" actually means
Almost all "new" containers are one-trip units: built at the factory, loaded once with cargo for the voyage, then sold. They have straight walls, fresh paint, clean floors and good door seals.
Used container condition grades
Sellers describe used containers in a few common ways:
- Cargo-worthy (CW) — structurally sound enough to ship cargo, normally with a valid CSC safety plate.
- Wind & watertight (WWT) — no holes, keeps out rain and wind; fine for storage but may not be certified to ship.
- As-is — sold with known damage; only worth it if the price reflects the repairs.
- Refurbished — a used unit repaired and repainted; check what was actually fixed.
Which should you buy?
| Use | Our suggestion |
|---|---|
| Storage (goods, equipment, farm) | Used — wind & watertight |
| Shop, kiosk, office, apartment | New / one-trip or refurbished |
| Shipping cargo abroad | Cargo-worthy with a valid CSC plate |
| Tight budget, any use | Used, inspected in person |
Whatever you choose, inspect it first — see the inspection checklist.
Frequently asked questions
Are used containers safe to buy?
Yes, if inspected. Check the floor, roof, doors and seals and look for structural rust. A good used container will last many years as storage.
How long does a shipping container last?
With basic maintenance — keeping the roof clear of standing water and treating rust spots — a container can last decades on land.
