Maybe you’re snacking on a banana, sipping some espresso, or sitting in entrance of your pc and taking a break from work to learn this text. Most definitely, these items—in addition to your smartphone, fridge, and just about each different object in your house—as soon as have been loaded onto a big container in a foreign country and traveled 1000’s of miles by way of ships crossing the ocean earlier than finally arriving at your step.
At the moment, an estimated 90% of the world’s goods are transported by sea, with 60% of that—together with just about all your imported fruits, devices, and home equipment—packed in massive metal containers. The relaxation is principally commodities like oil or grains which are poured instantly into the hull. In complete, about $14 trillion of the world’s items spend a while inside an enormous steel field.
Briefly, with out the standardized container, the world provide chain that society relies upon upon—and that I study—wouldn’t exist.
A latest scarcity of those containers is raising costs and snarling supply chains of thousands of products throughout the world. The scenario highlights the significance of the easy but important cargo containers that, from a distance, resemble Lego blocks floating on the sea.

Commerce earlier than the container
Since the daybreak of commerce, people have been using containers, sacks, barrels, and containers of various sizes to move items over lengthy distances. Phoenicians in 1600 B.C. Egypt ferried wooden, materials, and glass to Arabia in sacks by way of camel-driven caravans. And a whole bunch of years later, the Greeks used ancient storage containers known as amphorae to move wine, olive oil, and grain on triremes that plied the Mediterranean and neighboring seas to different ports in the area.
Whilst commerce grew extra superior, the strategy of loading and unloading as items have been transferred from one methodology of transportation to a different remained very labor-intensive, time-consuming, and costly, partially as a result of containers got here in all styles and sizes. Containers from a ship being transferred onto a smaller rail automobile, for instance, typically needed to be opened up and repacked right into a boxcar.
Completely different-sized packages additionally meant house on a ship couldn’t be successfully utilized, and likewise created weight and steadiness challenges for a vessel. And items have been extra more likely to expertise injury from dealing with or theft as a result of publicity.
A commerce revolution
The U.S. navy started exploring the use of standardized small containers to extra effectively transport weapons, bombs, and different materials to the entrance strains throughout World Conflict II.
But it surely was not till the Fifties that American entrepreneur Malcolm McLean realized that by standardizing the measurement of the containers being utilized in world commerce, loading and unloading of ships and trains might be no less than partially mechanized, thereby making the switch from one mode of transportation to a different seamless. This fashion merchandise might stay of their containers from the level of manufacture to supply, leading to lowered prices by way of labor and potential injury.
In 1956 McLean created the standard cargo container, which is mainly nonetheless the customary right now. He initially constructed it at a size of 33 ft—quickly elevated to 35—and 8 feet wide and tall.
This technique dramatically lowered the price of loading and unloading a ship. In 1956, manually loading a ship cost $5.86 per ton; the standardized container lower that price to simply 16 cents a ton. Containers additionally made it a lot simpler to guard cargo from the parts or pirates, since they’re fabricated from sturdy metal and stay locked throughout transport.
The U.S. made nice use of this innovation during the Vietnam War to ship provides to troopers, who generally even used the containers as shelters.
At the moment, the standard container size is 20 feet long, 8 ft vast, and 9 ft tall—a measurement that’s develop into referred to as a “20-foot-equivalent container unit,” or TEU. There are literally a number of completely different customary sizes, resembling 40 ft lengthy or a bit taller, although all of them have the similar width. One in every of the key benefits is that no matter measurement a ship makes use of, all of them, like Lego blocks, match neatly along with just about no empty areas.
This innovation made the trendy globalized world attainable. The amount of goods carried by containers soared from 102 million metric tons in 1980 to about 1.83 billion metric tons as of 2017. Most of the container visitors flows across the Pacific Ocean or between Europe and Asia.
Ships get enormous
The standardization of container sizes has additionally led to a surge in ship measurement. The extra containers packed on a ship, the extra a shipping firm can earn on every journey.
In actual fact, the common measurement of a container ship has doubled in the past 20 years alone. The largest ships crusing right now are capable of hauling 24,000 containers—that’s a carrying capability equal to how a lot a freight train 44 miles long might maintain. Put one other method, a ship named the Globe with a capability of 19,100 20-foot containers could haul 156 million pairs of shoes, 300 million pill computer systems, or 900 million cans of baked beans—in case you’re feeling hungry.
The Ever Given, the ship that blocked visitors by means of the Suez Canal for nearly every week in March 2021, has the same capability, 20,000 containers.
When it comes to price, think about this: The typical pre-pandemic worth of transporting a 20-foot container carrying over 20 tons of cargo from Asia to Europe was about the same as an economic system ticket to fly the similar journey.
Price of success
However the rising measurement of ships has a value, as the Ever Given incident confirmed.
Maritime shipping has grown more and more vital to world provide chains and commerce, but it was slightly invisible till the logjam and blockage of the Suez Canal. As the Ever Given was traversing the slender 120-mile canal, fierce wind gusts blew it to the bank, and its 200,000 tons of weight acquired it caught in the muck.
About 12% of the world’s global shipping traffic passes by means of this canal. At one level throughout the blockage, at least 369 ships were stuck waiting to move by means of the canal from both facet, costing an estimated $9.6 billion a day. That interprets to $400 million an hour, or $6.7 million a minute.
