Condition grades
Used containers aren't all the same. These are the terms you'll see on quotes, and what they mean for you.

Every container starts out shipping cargo. How many trips it has made, and how it was treated, decides the grade you see on a quote.
Grades aren't fully standardized between suppliers, so ask for photos of the actual unit.
The grades
New / one-trip
Built overseas and shipped once with cargo, then sold. Clean paint, few or no dents, tight doors. The right pick when looks matter or you plan to convert it.
Cargo-worthy (CW)
Used, but still sound enough to carry freight again. Expect dents, faded paint and surface rust on a solid frame. Some come with a survey or certificate if you ask.
Wind & water tight (WWT)
Keeps wind and rain out, but shows its age. Often the best value for plain storage where appearance doesn't matter.
As-is
Sold with known problems such as holes, heavy rust or damaged doors. Can work for parts or rough projects. Always see it or get photos first.
Refurbished
A used box that's been repaired and repainted. Quality depends on who did the work, so ask what was fixed.
Which grade should you pick?
- Plain storage, looks don't matter: WWT or cargo-worthy.
- Visible spot, HOA, or a finished build: one-trip.
- Shipping goods overseas: cargo-worthy, and ask about certification.
- Rough projects on a budget: as-is, after you've seen it.

Grade questions
What does cargo-worthy mean?
The container is considered structurally sound enough to carry freight again. It's a step above wind and water tight.
Is wind and water tight good enough for storage?
For most plain storage, yes. It should keep weather out, though it won't look new.
What is a one-trip container?
A new container that made a single trip with cargo from the factory before being sold.
