Your statutory rights
Warranty coverage is as described on this page and in your product listing or written order confirmation. Nothing in these warranty terms limits rights or remedies that cannot be waived under applicable law.
Container condition grades
Understanding these terms before you buy avoids disappointment on delivery.
| Grade | What it means | Watertight warranty |
|---|---|---|
| New / One Trip | Manufactured recently, used for a single cargo voyage. Near-new with minimal marking. | Yes |
| Cargo Worthy (CW) | Structurally sound and certified to Cargo Worthy standard for sea freight use. Expect surface rust, dents and previous repairs. This grade describes condition; it is not an offer of overseas delivery. | Yes |
| Wind & Watertight (WWT) | No longer certified for shipping but sound for storage. Cosmetic wear, rust and repairs are normal. | Yes |
| As Is | Sold in current condition with faults disclosed, priced accordingly. | No |
Surface rust, dents, patch repairs, mismatched paintwork and residual shipping-line markings are normal characteristics of used containers and are not defects.
