67-455: The Albert Canal has a standard depth of 3.4 metres (11 ft) and an overhead clearance of 6.7 metres (22 ft). To allow four-stacked container traffic, bridges over the canal are currently being heightened to allow for a 9.1 metres (30 ft) overhead. Between Antwerp and Liège, there is a difference in elevation of 56 metres (184 ft), and six sets of canal locks were needed to overcome this difference. Five canal locks each have

134-477: A 40-ft unit than for a 1 TEU box. Although 20-ft units mostly have heavy cargo, and are useful for stabilizing both ships and revenue, carriers financially penalize 1 TEU boxes by comparison. For container manufacturers, 40-foot High-Cubes now dominate market demand both for dry and refrigerated units. Manufacturing prices for regular dry freight containers are typically in the range of $ 1750–$ 2000 U.S. per CEU (container equivalent unit), and about 90% of

201-560: A clause in the International Longshoremen's Association (ILA) contract stipulated that the work of "stuffing" (filling) or "stripping" (emptying) a container within 50 miles (80 km) of a port must be done by ILA workers, or if not done by ILA, that the shipper needed to pay royalties and penalties to the ILA. Unions for truckers and consolidators argued that the ILA rules were not valid work preservation clauses, because

268-597: A crane. However they frequently do not have the upper corner fittings of ISO containers, and are not stackable, nor can they be lifted and handled by the usual equipment like reach-stackers or straddle-carriers. They are generally more expensive to procure. Basic terminology of globally standardized intermodal shipping containers is set out in standard: From its inception, ISO standards on international shipping containers, consistently speak of them sofar as 'Series 1' containers – deliberately so conceived, to leave room for another such series of interrelated container standards in

335-542: A lift of 10 metres (33 ft), and these are located in Genk , Diepenbeek , Hasselt , Kwaadmechelen , and Olen, Belgium . The sixth lock at Wijnegem has a lift of 5.45 metres (17.9 ft). During most of the 1930s, before the completion of the Albert Canal, it took about seven days to travel from Antwerp to Liège by water. In the 21st century, that same distance can be covered in about 18 hours. The Albert Canal

402-438: A means to bundle cargo and goods into larger, unitized loads that can be easily handled, moved, and stacked, and that will pack tightly in a ship or yard. Intermodal containers share a number of construction features to withstand the stresses of intermodal shipping, to facilitate their handling, and to allow stacking. Each has a unique ISO 6346 reporting mark. In 2012, there were about 20.5 million intermodal containers in

469-403: A new 35 ft (10.67 m) x 8 ft (2.44 m) x 8 ft 6 in (2.59 m) Sea-Land container was developed, the length determined by the maximum length of trailers then allowed on Pennsylvanian highways. Each container had a frame with eight corner castings that could withstand stacking loads. Tantlinger also designed automatic spreaders for handling the containers, as well as

536-407: A sustainable consumption. Cooper (2005) proposed a model to demonstrate the crucial role of product life spans for sustainable production and consumption. Durability, as a characteristic relating to the quality of goods that can be demanded by consumers, was not clear until an amendment of the law in 1994 relating to the quality standards for supplied goods. The condition of the economy is one of

603-462: A typical internal width of 2.44 m ( 96 + 1 ⁄ 8  in), (a gain of ~ 10 centimetres ( 3 + 15 ⁄ 16  in) over the ISO-usual 2.34 m ( 92 + 1 ⁄ 8  in), gives pallet-wide containers a usable internal floor width of 2.40 m ( 94 + 1 ⁄ 2  in), compared to 2.00 m ( 78 + 3 ⁄ 4  in) in standard containers, because

670-478: 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

804-426: 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

871-557: Is the ability of a product to perform its required function over a lengthy period under normal conditions of use without excessive expenditure on maintenance or repair". Several units may be used to measure the durability of a product according to its field of application such as years of existence, hours of use and operational cycles. The life span of household goods is significant for sustainable consumption . The longer product life spans could contribute to eco-efficiency and sufficiency, thus slowing consumption in order to progress towards

938-550: The 13.6 m (44 ft 7 + 3 ⁄ 8  in) swap bodies that are common for truck transport in Europe. The EU has started a standardization for pallet wide containerization in the European Intermodal Loading Unit (EILU) initiative. Many sea shipping providers in Europe allow these on board, as their external width overhangs over standard containers are sufficiently minor that they fit in

1005-538: The Ideal X , started container shipping on the US East Coast, Matson Navigation followed suit between California and Hawaii. Just like Pan-Atlantic 's containers, Matson's were 8 ft (2.44 m) wide and 8 ft 6 in (2.59 m) high, but due to California's different traffic code Matson chose to make theirs 24 ft (7.32 m) long. In 1968, McLean began container service to South Vietnam for

1072-593: The Derby Canal , which Outram had also promoted. By the 1830s, railways were carrying containers that could be transferred to other modes of transport. The Liverpool and Manchester Railway in the UK was one of these, making use of "simple rectangular timber boxes" to convey coal from Lancashire collieries to Liverpool, where a crane transferred them to horse-drawn carriages. Originally used for moving coal on and off barges, "loose boxes" were used to containerize coal from

1139-590: The ISO 6346 standard classifies a broad spectrum of container types in great detail. Aside from different size options, the most important container types are: Containers for offshore use have a few different features, like pad eyes , and must meet additional strength and design requirements, standards and certification, such as the DNV2.7-1 by Det Norske Veritas , LRCCS by Lloyd's Register , Guide for Certification of Offshore Containers by American Bureau of Shipping and

1206-559: The International standard ISO10855 : Offshore containers and associated lifting sets , in support of IMO MSC/Circ. 860 A multitude of equipment, such as generators, has been installed in containers of different types to simplify logistics – see § Containerized equipment for more details. Swap body units usually have the same bottom corner fixtures as intermodal containers, and often have folding legs under their frame so that they can be moved between trucks without using

1273-662: The Marie Maersk no longer use separate stacks in their holds, and other stacks above deck – instead they maximize their capacity by stacking continuously from the bottom of the hull, to as much as 21 high. This requires automated planning to keep heavy containers at the bottom of the stack and light ones on top to stabilize the ship and to prevent crushing the bottom containers. Regional intermodal containers, such as European, Japanese and U.S. domestic units however, are mainly transported by road and rail, and can frequently only be stacked up to two or three laden units high. Although

1340-965: The Swiss Museum of Transport and the Bureau International des Containers (BIC) held demonstrations of container systems for representatives from a number of European countries, and from the United States. A system was selected for Western Europe, based on the Netherlands' system for consumer goods and waste transportation called Laadkisten (lit. "Loading chests"), in use since 1934. This system used roller containers for transport by rail, truck and ship, in various configurations up to 5,500 kg (12,100 lb) capacity, and up to 3.1 by 2.3 by 2 metres (10 ft 2 in × 7 ft 6 + 1 ⁄ 2  in × 6 ft 6 + 3 ⁄ 4  in) in size. This became

1407-467: The U.S. Army Transportation Corps developed the "Transporter", a rigid, corrugated steel container, able to carry 9,000 pounds (4,100 kg). It was 8 ft 6 in (2.59 m) long, 6 ft 3 in (1.91 m) wide, and 6 ft 10 in (2.08 m) high, with double doors on one end, was mounted on skids, and had lifting rings on the top four corners. After proving successful in Korea,

1474-483: The U.S. Army entered Belgium further to the east on its way to liberate the rest of Belgium, and Luxembourg , and then proceed east to invade Nazi Germany . Hence, Belgium was liberated from the south by three different armies, two of which needed to cross the Albert Canal. In 2002, the canal carried a record 43 million tons of goods of various kinds, amounting to more than half the Belgian waterway total. The canal

1541-597: The twistlock mechanism that connects with the corner castings. Containers in their modern 21st-century form first began to gain widespread use around 1956. Businesses began 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. Two years after McLean's first container ship,

1608-401: The 9 ft 6 in (2.9 m) tall high-cube, as well as 4-foot-3-inch half-height (1.3 m) 20-foot (6.1 m) containers are equally counted as one TEU. Similarly, extra long 45 ft (13.72 m) containers are commonly counted as just two TEU, no different from standard 40 feet (12.19 m) long units. Two TEU are equivalent to one forty-foot equivalent unit (FEU). In 2014

1675-703: The Box: How Globalization Changed from Moving Stuff to Spreading Ideas and The Box: How the Shipping Container Made the World Smaller and the World Economy Bigger , said in an interview: Because of delays in the process, it's taking a container longer to go from its origin to its final destination where it's unloaded, so the container is in use longer for each trip. You've just lost a big hunk of

1742-654: The Transporter was developed into the Container Express (CONEX) box system in late 1952. Based on the Transporter, the size and capacity of the Conex were about the same, but the system was made modular, by the addition of a smaller, half-size unit of 6 ft 3 in (1.91 m) long, 4 ft 3 in (1.30 m) wide and 6 ft 10 + 1 ⁄ 2  in (2.10 m) high. CONEXes could be stacked three high, and protected their contents from

1809-738: The U.S. nor Europe. In November 1932, the first container terminal in the world was opened by the Pennsylvania Rail Road Company in Enola, Pennsylvania . Containerization was developed in Europe and the US as a way to revitalize rail companies after the Wall Street Crash of 1929 , in New York, which resulted in economic collapse and a drop in all modes of transport. In April 1951 at Zürich Tiefenbrunnen railway station ,

1876-651: The US military with great success. ISO standards for containers were published between 1968 and 1970 by the International Maritime Organization. These standards allow for more consistent loading, transporting, and unloading of goods in ports throughout the world, thus saving time and resources. The International Convention for Safe Containers (CSC) is a 1972 regulation by the Inter-governmental Maritime Consultative Organization on

1943-881: The biggest factors as well as the philosophy of money. Consumers want to use their money effectively and essentially get what they paid for, and in the best-case scenario, get more than what they paid for. In the pursuit of durable goods through the lifespans of the products and consumption of those products money and price dictate two of the biggest factors other than supply and demand. “At some point, people will realize that they can trade more easily if they use some intermediate good—money. This intermediate good should ideally be easy to handle, store and transport (function i). It should be easy to measure and divide to facilitate calculations (function ii). And it should be difficult to destroy so that it lasts over time (function iii)” (de Bruin 2023). Durable good falls into this category since ease of commerce and convenience are key factors into making it

2010-812: The canal by the German forces and the destruction of Fort Eben-Emael on 11 May 1940 was a milestone in the German invasion of Belgium . During the Liberation of Belgium by the Allies in September 1944, the Second Canadian Division was the first Allied unit to cross the Albert Canal. The British Army also crossed the Albert Canal on its way north across Belgium and into the Netherlands and

2077-401: The container, to avoid axle weight violations. The maximum gross weights that U.S. railroads accept or deliver are 52,900 lb (24,000 kg) for 20-foot containers, and 67,200 lb (30,500 kg) for 40-foot containers, in contrast to the global ISO-standard gross weight for 20-footers having been raised to the same as 40-footers in the year 2005. In the U.S., containers loaded up to

2144-452: The corrugated sides cause aerodynamic drag, and up to 10% fuel economy loss in road or rail transport, compared to smooth-sided vans. Standard containers are 8 feet (2.44 m) wide by 8 ft 6 in (2.59 m) high, although the taller "High Cube" or "hi-cube" units measuring 9 feet 6 inches (2.90 m) have become very common in recent years . By the end of 2013, high-cube 40 ft containers represented almost 50% of

2211-427: The development of containers, as well as their handling and transportation equipment. In 1949, while at Brown Trailers Inc. of Spokane, Washington , he modified the design of their stressed skin aluminum 30-foot trailer, to fulfil an order of two-hundred 30 by 8 by 8.5 feet (9.14 m × 2.44 m × 2.59 m) containers that could be stacked two high, for Alaska-based Ocean Van Lines . Steel castings on

2278-484: The eight corners, to allow gripping the box from above, below, or the side, and they can be stacked up to ten units high. Although ISO standard 1496 of 1990 only required nine-high stacking, and only of containers rated at 24,000 kg (53,000 lb), current Ultra Large Container Vessels of the Post New Panamax and Maersk Triple E class are stacking them ten or eleven high. Moreover, vessels like

2345-453: The elements. By 1965 the US military used some 100,000 Conex boxes, and more than 200,000 in 1967, making this the first worldwide application of intermodal containers. 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. From 1949 onward, engineer Keith Tantlinger repeatedly contributed to

2412-435: The extra width enables their users to either load two Euro-pallets end on end across their width, or three of them side by side (providing the pallets were neatly stacked, without overspill), whereas in standard ISO containers, a strip of internal floor-width of about 33 centimetres (13 in) cannot be used by Euro-pallets. As a result, while being virtually interchangeable: Some pallet-wides are simply manufactured with

2479-564: The fact that personal expenditures on durables exceeded the total value of $ 800 billion in 2000. In the year 2000 itself, durable goods production composed of approximately 60 percent of aggregate production within the manufacturing sector in the United States. Examples of consumer durable goods include vehicles , books , household goods ( home appliances , consumer electronics , furniture , musical instruments , tools , etc.), sports equipment , jewelry , medical equipment , and toys . Nondurable goods or soft goods ( consumables ) are

2546-508: The first post World War II European railway standard of the International Union of Railways – UIC-590 , known as "pa-Behälter". It was implemented in the Netherlands, Belgium, Luxembourg, West Germany, Switzerland, Sweden and Denmark. The use of standardized steel shipping containers began during the late 1940s and early 1950s, when commercial shipping operators and the US military started developing such units. In 1948

2613-476: The future. Basic dimensions and permissible gross weights of intermodal containers are largely determined by two ISO standards: Weights and dimensions of the most common (standardized) types of containers are given below. Forty-eight foot and fifty-three foot containers have not yet been incorporated in the latest, 2020 edition of the ISO 668. ISO standard maximum gross mass for all standard sizes except 10-ft boxes

2680-462: The global container fleet grew to a volume of 36.6 million TEU, based on Drewry Shipping Consultants' Container Census. Moreover, in 2014 for the first time in history 40-foot High-Cube containers accounted for the majority of boxes in service, measured in TEU. In 2019 it was noted by global logistics data analysis startup Upply that China's role as 'factory of the world' is further incentivizing

2747-640: The late 1780s, at places like the Bridgewater Canal . By the 1840s, iron boxes were in use as well as wooden ones. The early 1900s saw the adoption of closed container boxes designed for movement between road and rail. The first international standard for containers was established by the Bureau International des Containers et du Transport Intermodal (B.I.C.) in 1933, and a second one in 1935, primarily for transport between European countries. American containers at this time were not standardized, and these early containers were not yet stackable – neither in

2814-601: The late 18th century. In 1766 James Brindley designed the box boat 'Starvationer' with ten wooden containers, to transport coal from Worsley Delph (quarry) to Manchester by Bridgewater Canal . In 1795, Benjamin Outram opened the Little Eaton Gangway, upon which coal was carried in wagons built at his Butterley Ironwork. The horse-drawn wheeled wagons on the gangway took the form of containers, which, loaded with coal, could be transshipped from canal barges on

2881-519: The latter are known as High Cube or Hi-Cube ( HC or HQ ) containers. Depending on the source, these containers may be termed TEUs (twenty-foot equivalent units), reflecting the 20- or 40-foot dimensions. Invented in the early 20th century, 40-foot intermodal containers proliferated during the 1960s and 1970s under the containerization innovations of the American shipping company SeaLand . Like cardboard boxes and pallets , these containers are

2948-497: The maximum width of road vehicles in the region but is 6 inches (15 cm) wider than ISO-standard containers, and they are often not built strong enough to endure the rigors of ocean transport. The first North American containers to come to market were 48 feet (15 m) long. This size was introduced by container shipping company American President Lines (APL) in 1986. The size of the containers matched new federal regulations passed in 1983 which prohibited states from outlawing

3015-681: The name of an important predecessor of the ISO containers: the much smaller steel CONEX boxes used by the U.S. Army . Intermodal containers exist in many types and standardized sizes, but 90 percent of the global container fleet are "dry freight" or "general purpose" containers: durable closed rectangular boxes, made of rust-retardant Corten steel ; almost all 8 feet (2.44 m) wide, and of either 20 or 40 feet (6.10 or 12.19 m) standard length, as defined by International Organization for Standardization (ISO) standard 668:2020 . The worldwide standard heights are 8 feet 6 inches (2.59 m) and 9 feet 6 inches (2.90 m) –

3082-425: The operation of single trailers shorter than 48 feet long or 102 inches wide. This size being 8 feet (2.44 m) longer and 6 inches (15 cm) wider has 29% more volume capacity than the standard 40-ft High-Cube, yet costs of moving it by truck or rail are almost the same. In the late 1980s, the federal government announced it would once again allow an increase in the length of trailers to 53 feet (16 m) at

3149-479: The opposite of durable goods. They may be defined either as goods that are immediately consumed in one use or ones that have a lifespan of less than three years. Examples of nondurable goods include fast-moving consumer goods such as food , cosmetics , cleaning products , medication , clothing , packaging and fuel . While durable goods can usually be rented as well as bought, nondurable goods generally are not rented. According to Cooper (1994, p5) " durability

3216-492: The process can easily cause major delays everywhere up and down the supply chain. The reliance on containers exacerbated some of the economic and societal damage from the 2021 global supply chain crisis of 2020 and 2021, and the resulting shortages related to the COVID-19 pandemic . In January 2021, for example, a shortage of shipping containers at ports caused shipping to be backlogged. Marc Levinson, author of Outside

3283-722: The rail cargo weight limit cannot move over the road, as they will exceed the U.S. 80,000 lb (36,000 kg) highway limit. Australian RACE containers are also slightly wider to optimise them for the use of Australia Standard Pallets , or are 41 ft (12.5 m) long and 2.5 m (8 ft 2 in) wide to be able to fit up to 40 pallets. European pallet wide (or PW) containers are minimally wider, and have shallow side corrugation, to offer just enough internal width, to allow common European Euro-pallets of 1.20 m ( 47 + 1 ⁄ 4  in) long by 0.80 m ( 31 + 1 ⁄ 2  in) wide, to be loaded with significantly greater efficiency and capacity. Having

3350-445: The safe handling and transport of containers. It decrees that every container traveling internationally be fitted with a CSC Safety-approval Plate. This holds essential information about the container, including age, registration number, dimensions and weights, as well as its strength and maximum stacking capability. Longshoremen and related unions around the world struggled with this revolution in shipping goods. For example, by 1971

3417-487: The same, ISO-standard floor structure, but with the side-panels welded in, such that the ribs/corrugations are embossed outwards, instead of indenting to the inside. This makes it possible for some pallet-wides to be just 2.462 m ( 96 + 7 ⁄ 8  in) wide, but others can be 2.50 m ( 98 + 3 ⁄ 8  in) wide. The 45 ft (13.72 m) pallet-wide high-cube container has gained particularly wide acceptance, as these containers can replace

3484-577: The ship lines want to ship them empty back to Asia, rather than letting them go to South Dakota and load over the course of several days. So we've had exporters in the United States complaining that they have a hard time finding a container that they can use to send their own goods abroad. Ninety percent of the global container fleet consists of "dry freight" or "general purpose" containers – both of standard and special sizes. And although lengths of containers vary from 8 to 56 feet (2.4 to 17.1 m), according to two 2012 container census reports about 80% of

3551-451: The standard, general purpose container, many variations exist for use with different cargoes. The most prominent of these are refrigerated containers (also called reefers ) for perishable goods, that make up 6% of the world's shipping boxes. Tanks in a frame, for bulk liquids, account for another 0.75% of the global container fleet. Although these variations are not of the standard type, they mostly are ISO standard containers – in fact

3618-451: The standards. Empty weight ( tare weight ) is not determined by the standards, but by the container's construction, and is therefore indicative, but necessary to calculate a net load figure, by subtracting it from the maximum permitted gross weight. The bottom row in the table gives the legal maximum cargo weights for U.S. highway transport, and those based on use of an industry common tri-axle chassis. Cargo must also be loaded evenly inside

3685-894: The start of 1990. Anticipating this change, 53 foot containers were introduced in 1989. These large boxes have 60% more capacity than 40' containers, enabling shippers to consolidate more cargo into fewer containers. Durable good In economics , a durable good or a hard good or consumer durable is a good that does not quickly wear out or, more specifically, one that yields utility over time rather than being completely consumed in one use. Items like bricks could be considered perfectly durable goods because they should theoretically never wear out. Highly durable goods such as refrigerators or cars usually continue to be useful for several years of use, so durable goods are typically characterized by long periods between successive purchases. Durable goods are known to form an imperative part of economic production. This can be exemplified from

3752-401: The top corners provided lifting and securing points. In 1955, trucking magnate Malcom McLean bought Pan-Atlantic Steamship Company , to form a container shipping enterprise, later known as Sea-Land . The first containers were supplied by Brown Trailers Inc, where McLean met Keith Tantlinger , and hired him as vice-president of engineering and research. Under the supervision of Tantlinger,

3819-418: The total capacity because the containers can't be used as intensively. We've had in the United States an additional problem, which is that the ship lines typically charge much higher rates on services from Asia to North America than from North America to Asia. This has resulted in complaints, for example, from farmers and agricultural companies, that it's hard to get containers in some parts of the country because

3886-404: The two ends are quite rigid, containers flex somewhat during transport. Container capacity is often expressed in twenty-foot equivalent units ( TEU , or sometimes teu ). A twenty-foot equivalent unit is a measure of containerized cargo capacity equal to one standard 20-foot (6.1 m) long container. This is an approximate measure, wherein the height of the box is not considered. For example,

3953-452: The use of 40-foot containers, and that the computational standard 1 TEU boxes only make up 20% of units on major east–west liner routes, and demand for shipping them keeps dropping. In the 21st century, the market has shifted to using 40-foot high-cube dry and refrigerated containers more and more predominantly. Forty-foot units have become the standard to such an extent that the sea freight industry now charges less than 30% more for moving

4020-641: The usual interlock spaces in ship's holds, as long as their corner-castings patterns (both in the floor and the top) still match with regular 40-foot units, for stacking and securing. The North American market has widely adopted containerization, especially for domestic shipments that need to move between road and rail transport. While they appear similar to the ISO-standard containers, there are several significant differences: they are considered High-Cubes based on their 9 ft 6 in (2.90 m) ISO-standard height, their 102-inch (2.6 m) width matches

4087-466: The work of stuffing and stripping containers away from the pier had not traditionally been done by ILA members. In 1980 the Supreme Court of the United States heard this case and ruled against the ILA. Some experts have said that the centralized, continuous shipping process made possible by containers has created dangerous liabilities: one bottleneck, delay, or other breakdown at any point in

4154-592: The world of varying types to suit different cargoes. Containers have largely supplanted the traditional break bulk cargo ; in 2010, containers accounted for 60% of the world's seaborne trade. The predominant alternative methods of transport carry bulk cargo , whether gaseous, liquid, or solid—e.g., by bulk carrier or tank ship , tank car , or truck . For air freight , the lighter weight IATA -defined unit load devices are used. Containerization has its origins in early coal mining regions in England beginning in

4221-486: The world's containers are either 20- or 40-foot standard-length boxes of the dry freight design. These typical containers are rectangular, closed box models, with doors fitted at one end, and made of corrugated weathering steel (commonly known as CorTen) with a plywood floor. Although corrugating the sheet metal used for the sides and roof contributes significantly to the container's rigidity and stacking strength, just like in corrugated iron or in cardboard boxes ,
