Shipping Container Conditions Explained: One-Trip, Cargo Worthy, Wind- and Watertight, and As-Is

Comparison of one-trip, cargo-worthy, wind-and-watertight, and as-is shipping container conditions

Container Condition Guide

Condition labels are useful only when the seller explains what they mean.

There is no single universal retail grading system used exactly the same way by every container seller. Get the promised condition in writing and inspect the unit or request current photos.

One-Trip

One-trip containers have generally made one loaded trip from the manufacturer. They are usually the cleanest-looking option and offer a long expected service life. They may still show handling marks, small dents, scratches, or surface oxidation.

Cargo Worthy

A cargo-worthy container is structurally suitable for cargo transport after inspection. It may have dents, patches, surface rust, worn paint, and an older appearance. Cargo worthy describes structural transport suitability—not cosmetic quality.

Wind- and Watertight

A wind- and watertight container is generally intended for stationary storage and should keep out normal wind and rain. It may not have a current cargo inspection and may not qualify for international transport. The term does not guarantee attractive paint, odor-free flooring, easy doors, or a dent-free roof.

Used Storage Grade

Some sellers use this term for a functional used unit suited to ground-level storage. Because the phrase is not standardized, ask whether it includes leak protection, working doors, sound floors, structural integrity, and any repair warranty.

As-Is

An as-is container is sold in its present condition. It may need roof, floor, door, seal, rail, or structural repairs. Buyers should inspect carefully and understand that low price can be offset by repair and delivery costs.

Salvage

Salvage containers may have severe corrosion, structural damage, major holes, weak floors, damaged corner posts, or doors that do not function properly. They are generally best for parts, scrap, or specialized projects after professional evaluation.

What to Inspect

  • Roof bows, holes, patches, and standing-water areas
  • Corner posts, top and bottom rails, and underside crossmembers
  • Floor softness, rot, contamination, and strong odors
  • Door alignment, locking bars, hinges, gaskets, and lockbox
  • Daylight visible from inside with the doors closed
  • Whether photos show the exact unit or only a representative condition

Put the Condition on the Invoice

The written agreement should identify the condition, size, height, exact or representative unit, included repairs, delivery charge, and any leak or condition warranty. Verbal descriptions are difficult to enforce when the delivered unit does not match expectations.

Choose condition based on use—not appearance alone.
