Container grades can be confusing, and the grade you choose has a direct effect on price. This guide explains each one in plain language.
One-trip containers
One-trip containers made a single voyage. They are nearly new, with clean paint and sound floors. They carry the highest price and are the best choice for homes, offices, and visible installations.
Cargo-worthy (CW)
A cargo-worthy container is certified to be structurally safe for shipping cargo. It may show dents and surface rust, but the frame, doors, and seals are sound. It sits in the middle on price and works well if you may ship or relocate the box later.
Wind and watertight (WWT)
WWT containers keep out wind and water but are not certified for ocean cargo. They cost less than CW and suit stationary storage on a farm, yard, or job site.
Quick comparison
- One-trip: best look, longest life, highest price.
- CW: certified structure, moderate price.
- WWT: weatherproof storage, lower price.
Which grade fits your project?
- Storage only: WWT or CW, see storage containers.
- Climate-controlled use: start with insulated containers.
- Modified space or home: one-trip, see one-bedroom container homes.
- Cold storage: reefer containers.
