When evaluating a used shipping container, inspect the roof, walls, doors, seals, flooring, and underside for significant damage or corrosion. The doors should open, close, and latch properly, and the container’s condition grade should match how you plan to use it. Also confirm the size, delivery requirements, and available space at your site before purchasing.

One Trip Containers

- Structurally Sound – Inspected to ensure watertight integrity and fully operational doors.

If you plan to use a cargo-worthy container for international shipping, confirm that it has a valid CSC safety approval plate and meets all current inspection requirements.
Wind & Watertight Containers (WWT)
Wind- and watertight containers provide an economical solution for secure, on-site storage. These units are inspected to ensure that they do not have holes or leaks that would allow wind or water to enter under normal conditions.
- No Leaks – Container is sealed to prevent water intrusion.
- Properly Sealing Doors – Doors close and latch securely.
- Solid Flooring – Floors are intact and structurally sound.
- Ideal for Storage – Perfect for keeping equipment, inventory, or personal items safe and dry.
Wind- and watertight containers typically have visible cosmetic wear, including dents, scratches, surface rust, and faded paint. They are best suited for stationary storage and should not be assumed to meet international shipping requirements.
