Condition Options at a Glance

Wind and Watertight (WWT)

Common use: On-site storage.

Cargo Worthy

Common use: Cargo transportation or storage where structural condition matters.

IICL

Common use: Buyers seeking a higher used-container inspection standard.

Export: Confirm current documentation for the intended shipment.

One-Trip

Common use: Storage or projects where a newer appearance is preferred.

Export: Requirements still depend on the intended shipment.

Relative position: Commonly priced above used options.

Wind and Watertight (WWT)

Wind and Watertight (WWT) is commonly discussed for used containers intended for on-site storage. The practical focus is whether the container closes properly and helps keep ordinary wind and rain from entering. It does not mean cosmetically new, damage-free, or currently certified for export.

Expect possible dents, faded paint, scratches, surface rust, patches, repairs, and shipping markings. Door operation, seals, roof and wall condition, floors, visible openings, and intended use all matter.

Cargo Worthy

Cargo Worthy describes a container considered structurally suitable for cargo transportation when supported by the appropriate current inspection and documentation. Cosmetic wear can still be present. If export use is planned, confirm exactly which inspection and documents are required for the shipment.

IICL

IICL refers to an inspection standard commonly associated with the container-leasing industry. These containers may be held to higher repair criteria than other used categories. Availability varies, and the label should not replace confirmation of the specific unit, intended use, and required documentation.

One-Trip Containers

A one-trip container has generally completed one cargo trip from its manufacturing region. It is usually newer and cleaner in appearance than a typical used container, but it may still show minor scratches, rub marks, small dents, or handling marks. Color, size, height, doors, vents, and other configurations depend on current availability.

Which Shipping Container Is Right for Me?

The intended use, appearance expectations, required documentation, budget priorities, size, configuration, and delivery site should guide the decision.
