One-trip vs cargo-worthy vs WWT.
BY XIVSTORAGE · PUBLISHED JULY 14, 2026 · UPDATED JULY 14, 2026
Container grades answer different questions. One-trip speaks largely to age and use history, cargo-worthy to cargo-service condition when documented, and WWT to stationary weather-resistant storage. None is a complete inspection report by itself.
Side by side
| One-trip | Cargo-worthy | WWT | |
|---|---|---|---|
| HISTORY | Generally one cargo journey | Used, typically 10–15 years | Used, often older |
| COSMETICS | Minor handling wear | Dents, patches, surface rust normal | More wear than CW |
| CARGO USE | Usually eligible with current documents | Eligible when unit-specific documentation is current | Not represented for cargo |
| WARRANTY (XIVSTORAGE) | 5-yr limited structural | 30-day leak-free | 30-day leak-free |
| BEST FOR | Appearance, conversions, long ownership | Working storage, documented cargo | Stationary dry storage value |
Photos to request
Ask whether photos are exact-unit or representative, and request door, roof, floor, and interior light-leak shots for used units.
Common misleading phrases
“Like new” for used stock, “certified” without a current document, and “watertight” presented as flood-proof. The written grade standard controls — our definitions are published here.
Decide by use
Conversion or resale: one-trip. Export or documented cargo: cargo-worthy with current papers. Dry stationary storage on a budget: WWT.
