A shipping container is a container with strength suitable to withstand shipment, storage, and handling. Shipping containers range from large reusable steel boxes used for intermodal shipments to the ubiquitous corrugated boxes. In the context of international shipping trade, "container" or "shipping container" is virtually synonymous with "intermodal freight container" (sometimes informally called a "sea can"), a container designed to be moved from one mode of transport to another without unloading and reloading.

Freight containers are a reusable transport and storage unit for moving products and raw materials between locations or countries. There are about seventeen million intermodal containers in the world, and a large proportion of the world's long-distance freight generated by international trade is transported in shipping containers. In addition, it is estimated that several million of these containers have now been discarded due to the shipping cost of sending them back to their port of origin. Their invention made a major contribution to the globalization of commerce in the second half of the 20th century, dramatically reducing the cost of transporting goods and hence of long-distance trade. [2] [3]
Specialized shipping containers include: high cube containers (providing an extra 1 ft (305 mm) in height to standard shipping containers), pallet wides, open tops, side loaders, double door or tunnel-tainers, and temperature controlled containers. Another specialized container, known as Transtainer, is a portable fuel and oil freight container. The hybrid bulk fuel tank is originally intended for the construction, mining, logging and farming sectors. The tank can be used to transport and store bulk fuels as well as dangerous liquids, by road, rail and sea. [4] Sea containers are crucial for modern logistics, offering a cost-effective storage and shipping solution. These durable containers, designed for international transportation, provide secure storage for goods with robust steel construction. Beyond shipping, they find applications in on-site storage and modular living or workspaces. Sea containers for sale provide an accessible and convenient solution, meeting diverse needs and promoting sustainability through their reuse.
Reusable steel boxes for use as truck-sized shipping containers first came into use around 1956. It took some time for businesses to devise a structured process to utilize and to get optimal benefits from the role and use of shipping containers. Over time, the invention of the modern telecommunications of the late 20th-century made it highly beneficial to have standardized shipping containers, and made these shipping processes more standardized, modular, easier to schedule and easier to manage. [5]
Corrugated boxes are commonly used as shipping containers [6] (more than 90% of all shipping containers are of this type). [6] [7] They are made of corrugated fiberboard which is lightweight, recyclable, and strong enough to ship a variety of products.
Wooden boxes are often used for shipping heavy and dense products. They are sometimes specified for shipments of government or military shipments.
A crate is a large container, often made of wood, used to transport large, heavy or awkward items. A crate has a self-supporting structure, with or without sheathing.
Reusable plastic versions include:
An intermediate bulk container (IBC, IBC Tote, IBC Tank) is a multi-use container employed for the general transport, storage, and handling of bulk fluids and materials. IBC tanks are compatible with, and resistant to, an extensive list of chemicals, acids, caustics, as well as inert materials and food grade consumables. IBCs are commonly manufactured from the following materials:
Some IBC engineering models are foldable (collapsible) for space-saving breakdown following use.
A flexible intermediate bulk container, FIBC, big bag, bulk bag, or super sack is a standardized container in large dimensions for storing and transporting granular products. It is often made of a woven synthetic material.
A bulk box, bulk bin, skid box, or tote box is a pallet size box used for storage and shipping of bulk quantities.
Drums are cylindrical shipping containers made of steel, plastic or fiber. They are often used for liquids and granular materials.
Insulated shipping containers are a type of packaging used to ship temperature sensitive products such as foods, pharmaceuticals, and chemicals. They are used as part of a cold chain to help maintain product freshness and efficacy.
Some pails are used as shipping containers. [8]
A Unit Load Device (ULD), is a container used to transport cargo on commercial aircraft. It 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
Custom containers are used for shipments of products such as scientific instruments, weapons and aviation components. [9] Customized cushioning, blocking and bracing, carrying handles, lift rings, locks, etc. are common to facilitate handling and to protect the contents. Often, these shipping containers are reusable.
The reusable ifco tray ("international fruit container") is used in Europe for transportation of fruit, vegetables, and fish.
Flight cases and transit cases are usually custom designed for shipping and carrying fragile equipment: audio visual, camera, instruments, etc. Although generally light in construction, they tend to have reinforced edges and corners.
Road cases are often used for shipping musical instruments and theater props.
Many types of shipping containers are reusable. Steel drums are frequently reconditioned and reused. Gas cylinders, transit cases and sometimes even corrugated boxes are reused.
The widespread availability and relative cheapness of used intermodal shipping containers meant that architects began to consider them as an alternative to traditional building materials. [10] Used shipping containers have been converted for use in housing, and as retail and office spaces. [11] [12] Examples of its use include the Cité A Docks student housing project in Le Havre, France; [13] the Wenckehof container village in Amsterdam; [14] the portable Puma City store in US cities; [15] [16] the food and retail Boxpark in London; [17] the Dordoy Bazaar in Bishkek, Kyrgyzstan; [18] the temporary mall Re:START in Christchurch, New Zealand built after the 2011 Christchurch earthquake, [19] and as intensive-care units in temporary hospitals during the COVID-19 pandemic. [20] The Smoky Park Supper Club in Asheville, North Carolina, opened in 2015, was constructed from 19 containers and is considered " "America's largest recycled shipping container restaurant." [21]
It has however been pointed out there are problems with recycling shipping containers, that it may not be as ecologically friendly or cheap an option as it might appear. The containers may be coated with harmful chemicals such as chromate, phosphorus, and lead-based paints, while its wooden floors may be treated with toxic insecticides, and some cost and effort are involved in modifying containers to make them habitable. [10] Others have noted various issues such as space constraint, insulation, and structural weakness if too much steel is cut out of the containers. [22] [23]
Shipping containers are used in the film and television industry for building temporary sets. Shipping containers can be stacked on top of each other and used as reinforced scaffold that large-scale film sets can be built against. An example can be seen at Leavesden Studios, England; an area of the studio backlot is allocated to spare containers when not in use.[ citation needed ]
Reefer containers or refrigerated containers are containers built to haul refrigerated or frozen products. These containers can be repurposed for container housing or prefabricated for housing purposes. The advantage is the insulation in the walls, ceiling, and floor compared to corrugated metal in standard shipping containers that can get very hot or cold from the weather outside. Prefabricated reefer containers with the wiring ran through the walls and the plumbing ran through the ceiling and floor before the insulation, interior walls, and floors are installed would be more practical than trying to do that with a repurposed used reefer container. [24]
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.
In transportation, freight refers to goods conveyed by land, water or air, while cargo refers specifically to freight when conveyed via water or air. In economics, freight refers to goods transported at a freight rate for commercial gain. The term cargo is also used in case of goods in the cold-chain, because the perishable inventory is always in transit towards a final end-use, even when it is held in cold storage or other similar climate-controlled facilities, including warehouses.
A box is a container with rigid sides used for the storage or transportation of its contents. Most boxes have flat, parallel, rectangular sides. Boxes can be very small or very large and can be used for a variety of purposes, from functional to decorative.
A drum is a cylindrical shipping container used for shipping bulk cargo. Drums can be made of steel, dense paperboard, or plastic, and are generally used for the transportation and storage of liquids and powders. Drums are often stackable, and have dimensions designed for efficient warehouse and logistics use. This type of packaging is frequently certified for transporting dangerous goods. Proper shipment requires the drum to comply with all applicable regulations.
A pallet is a flat transport structure, which supports goods in a stable fashion while being lifted by a forklift, a pallet jack, a front loader, a jacking device, or an erect crane. Many pallets can handle a load of 1,000 kg (2,200 lb). While most pallets are wooden, pallets can also be made of plastic, metal, paper, and recycled materials.
A refrigerator car is a refrigerated boxcar (U.S.), a piece of railroad rolling stock designed to carry perishable freight at specific temperatures. Refrigerator cars differ from simple insulated boxcars and ventilated boxcars, neither of which are fitted with cooling apparatus. Reefers can be ice-cooled, come equipped with any one of a variety of mechanical refrigeration systems, or use carbon dioxide or liquid nitrogen as a cooling agent. Milk cars may or may not include a cooling system, but are equipped with high-speed trucks and other modifications that allow them to travel with passenger trains.
A Slip sheet is “a corrugated, solid fiber, or plastic sheet onto which a unit load can be assembled. A protruding short panel can be grasped by the jaws of a pull-pack truck and the load pulled back onto the pull-pack platform.”
A distribution center for a set of products is a warehouse or other specialized building, often with refrigeration or air conditioning, which is stocked with products (goods) to be redistributed to retailers, to wholesalers, or directly to consumers. A distribution center is a principal part, the order processing element, of the entire order fulfillment process. Distribution centers are usually thought of as being demand driven. A distribution center can also be called a warehouse, a DC, a fulfillment center, a cross-dock facility, a bulk break center, and a package handling center. The name by which the distribution center is known is commonly based on the purpose of the operation. For example, a "retail distribution center" normally distributes goods to retail stores, an "order fulfillment center" commonly distributes goods directly to consumers, and a cross-dock facility stores little or no product but distributes goods to other destinations.
Truckload shipping is freight transport in which a semi-trailer or intermodal container is filled entirely with one type of cargo. It differs from less-than-truckload shipping (LTL) in which freight from multiple customers is combined in one trailer. A truckload carrier is a trucking company that contracts entire trailer-load to a single customer.
Less-than-truckload shipping or less than load (LTL) is the transportation of an amount of freight sized between individual parcels and full truckloads. Parcel carriers handle small packages and freight that can be broken down into units less than approximately 150 pounds (68 kg). Full truckload carriers move entire semi-trailers. Semi-trailers are typically between 26 and 53 feet and require a substantial amount of freight to make such transportation economical. The term LTL can refer to the freight itself, or to the carrier that transports the such freight.
Intermediate bulk containers are industrial-grade containers engineered for the mass handling, transport, and storage of liquids, semi-solids, pastes, or solids. The two main categories of IBC tanks are flexible IBCs and rigid IBCs. Many IBCs are reused or repurposed.
A containerized housing unit, usually abbreviated as CHU is an ISO shipping container pre-fabricated into a living quarters. Such containers can be transported by container ships, railroad cars, planes, and trucks that are capable of transporting intermodal freight transport cargo.
A bulk box, also known as a bulk bin, skid box, pallet box, bin box, gaylord, or octabin, is a pallet-size box used for storage and shipping of bulk or packaged goods. Bulk boxes can be designed to hold many different types of items such as plastic pellets, watermelons, electronic components, and even liquids; some bulk boxes are stackable.
The term unit load refers to the size of an assemblage into which a number of individual items are combined for ease of storage and handling, for example a pallet load represents a unit load which can be moved easily with a pallet jack or forklift truck, or a container load represents a unit for shipping purposes. A unit load can be packed tightly into a warehouse rack, intermodal container, truck or boxcars, yet can be easily broken apart at a distribution point, usually a distribution center, wholesaler, or retail store for sale to consumers or for use.
An ammunition box or cartridge box is a container designed for safe transport and storage of ammunition. It is typically made of metal, wood, and corrugated fiberboard, etc. Boxes are labelled with caliber, quantity, and manufacturing date, lot number, UN dangerous goods labels.
Load securing, also known as cargo securing, is the securing of cargo for transportation. According to the European Commission Transportation Department “it has been estimated that up to 25% of accidents involving trucks can be attributable to inadequate cargo securing”. Cargo that is improperly secured can cause severe accidents and lead to the loss of cargo, lives, and vehicles, or cause environmental hazards.
Corrugated box design is the process of matching design factors for corrugated fiberboard or corrugated plastic boxes with the functional physical, processing and end-use requirements. Packaging engineers work to meet the performance requirements of a box while controlling total costs throughout the system. Corrugated boxes are shipping containers used for transport packaging and have important functional and economic considerations.
Shelf-ready packaging (SRP) and retail-ready packaging (RRP) refers to the packaging of a product so that it is delivered to a retailer in packaging which is optimized for efficient stocking and sale.
Reusable packaging is manufactured of durable materials and is specifically designed for multiple trips and extended life. A reusable package or container is "designed for reuse without impairment of its protective function." The term returnable is sometimes used interchangeably but it can also include returning packages or components for other than reuse: recycling, disposal, incineration, etc. Typically, the materials used to make returnable packaging include steel, wood, polypropylene sheets or other plastic materials.
A banana box is a type of corrugated box for transportation of bananas. It often consists of a separate lower part and a telescoping lid. Carrying handles and vent holes allow banana respiration and permit access to processing gasses such as ethylene oxide for ripening. The hole in the bottom is usually covered with a thin sheet of paperboard or corrugated board so that the bananas do not fall out, and a layer of plastic is usually placed between the bananas and the box.
