Container Grades & Conditions: What the Terms Mean
Container condition terms can sound similar but are used for different purposes. This guide provides a practical overview of common terms buyers may encounter when evaluating a shipping container for international freight, a project, or another qualified use.
The terms
Four terms buyers hear most
New One-Trip Containers
Newer containers commonly moved on an initial trip from the manufacturing region. They typically present in the best cosmetic condition available on the market, though condition, specification and availability still vary unit by unit.
Last-Trip Containers
A last-trip container is an older used container purchased for one final loaded international shipment. Unlike a one-tripper, which has carried cargo only once since manufacture, a last-tripper has spent years in active service and may show dents, surface rust, repairs, faded paint and other cosmetic wear. The container must still meet cargo-worthy standards and satisfy the carrier's certification, inspection, identification and booking requirements for its final voyage. After arrival, the container is typically retained for storage, repurposed or retired from international shipping service.
Cargo-Worthy Containers
Condition assessed as suitable for eligible international freight use. Depending on the shipment, documentation may be required, and carrier or shipment confirmation may be needed before loading.
Wind & Water Tight Containers
Generally refers to a container that is closed, structurally enclosed, and intended to keep out normal wind and rain. It indicates weather protection, but suitability for international ocean freight still requires confirmation.
Choosing
Matching the grade to the shipment
A container's grade or condition should be matched to the actual shipment, carrier, cargo, project, and documentation requirements. Ask Pro Box for help selecting the right option.
