Shipping container – a container with strength suitable to withstand shipment, storage, and handling. Shipping containers – large reusable steel boxes used for intermodal shipments. In the context of international shipping trade, “container” or “shipping container” usually means “(standard) intermodal freight container” (a container designed to be moved from one mode of transport to another without unloading and reloading).

Unit load device (ULD) – a container used to transport cargo on commercial aircraft. A ULD can be a pallet or container used to load luggage, freight, and mail on wide-body aircraft and specific narrow-body aircraft. It allows a large quantity of cargo to be bundled into a single unit. Since this leads to fewer units to load, it saves ground crews time and effort and helps prevent delayed flights. Each ULD has its own packing list, manifest, or tracking identification to improve control and tracking of contents.
