Containerization is a system of intermodal freight transport using intermodal containers. Containerization, also referred as container stuffing or container loading, is the process of unitization of cargoes in exports. Containerization is the predominant form of unitization of export cargoes, as opposed to other systems such as the barge system or palletization. The containers have standardized dimensions. They can be loaded and unloaded, stacked, transported efficiently over long distances, and transferred from one mode of transport to another—container ships, rail transport flatcars, and semi-trailer trucks—without being opened. The handling system is mechanized so that all handling is done with cranes and special forklift trucks. All containers are numbered and tracked using computerized systems.
An intermodal container, often called a shipping container, or cargo container, (or simply “container”) is a large metal crate designed and built for intermodal freight transport, meaning these containers can be used across different modes of transport – such as from ships to trains to trucks – without unloading and reloading their cargo. Intermodal containers are primarily used to store and transport materials and products efficiently and securely in the global containerized intermodal freight transport system, but smaller numbers are in regional use as well. It is like a boxcar that does not have wheels. Based on size alone, up to 95% of intermodal containers comply with ISO standards, and can officially be called ISO containers. These containers are known by many names: freight container, sea container, ocean container, container van or sea van, sea can or C can, or MILVAN, or SEAVAN. The term CONEX (Box) is a technically incorrect carry-over usage of the name of an important predecessor of the ISO containers: the much smaller steel CONEX boxes used by the U.S. Army.
A container ship is a cargo ship that carries all of its load in truck-size intermodal containers, in a technique called containerization. Container ships are a common means of commercial intermodal freight transport and now carry most seagoing non-bulk cargo.
Intermodal freight transport involves the transportation of freight in an intermodal container or vehicle, using multiple modes of transportation, without any handling of the freight itself when changing modes. The method reduces cargo handling, and so improves security, reduces damage and loss, and allows freight to be transported faster. Reduced costs over road trucking is the key benefit for inter-continental use. This may be offset by reduced timings for road transport over shorter distances.

Hamburg Südamerikanische Dampfschifffahrts-Gesellschaft A/S & Co KG, widely known as Hamburg Süd, was a German container shipping company. Founded in 1871, Hamburg Süd was among the market leaders in the North–South trade. It also served all significant East–West trade lanes.
Malcom Purcell McLean was an American businessman who invented the modern intermodal shipping container, which revolutionized transport and international trade in the second half of the twentieth century. Containerization led to a significant reduction in the cost of freight transportation by eliminating the need for repeated handling of individual pieces of cargo, and also improved reliability, reduced cargo theft, and cut inventory costs by shortening transit time. Containerization is a major driver of globalization.
Seatrain Lines, officially the Over-Seas Shipping Company, was a shipping and transportation company conducting operations in the Americas and trans-Pacific regions. Seatrain Lines began intermodal freight transport in December 1928 by transporting entire loaded railroad freight cars between the United States and Cuba. The specially designed ship Seatrain, built in England, was followed in 1932 by two larger ships built in the United States and in 1939 by two additional ships. By the outbreak of World War II the company was operating five ships that became important in the war effort and basis for the design of fifty new ships for military use. A series of business setbacks amid the rise of containerized shipping left the company in perilous financial condition in the 1970s. Seatrain Lines shut down in 1981 after filing for bankruptcy.
SS Ideal X, a converted World War II T-2 oil tanker, was the first commercially successful container ship.

The CONEX box, a portmanteau of "Container, express", is a type of cargo container that was developed during the Korean War and was used to transport and store supplies during the Korean and Vietnam wars. It was reinvented by Malcom McLean to form the standard intermodal shipping container, often called an ISO box, after ISO 668/ISO 6346, that is used widely by container shipping companies today.

The Type C7 ship(Lancer Class) is a United States Maritime Administration (MARAD) designation for a cargo ship and the first US purpose-built container ship. The vessels were constructed in US shipyards and entered service starting in 1968. As US-built ships they were Jones Act qualified for shipments between US domestic ports. Under the Jones Act, domestic US maritime trade is restricted to US-built and flagged vessels of US owners and crewed by predominantly US-citizens. The last active Lancer container-configured ship was scrapped in 2019. Lancers of the vehicle Roll-on/Roll-off (RO/RO) configuration remain held in the Ready Reserve Force, National Defense Reserve Fleet and the US Navy Military Sealift Command. All are steam powered.
