The Whole World Uses the Same Shipping Box
Packed once in Kansas, it rides train, ship, and truck to Russia without being opened.
Wendover Productions · Containerization: The Most Influential Invention That You've Never Heard OfAcross the world, shippers use one size of steel shipping box.
A manufacturer packs the container once, and no hands touch the goods inside until it reaches the distributor, vendor, or shopper. In between, that same box fits the train to the port, the ship across the ocean, and the truck onward. A box loaded in Kansas can ride the rails to the dock, cross to China by sea, and finish by road in Russia. Some planes are now being built to fit these containers.
That common size is remarkable because countries cannot settle on a common currency, plug type, video-disc standard, or whether cars should keep left or right.
The system started April 26, 1956, when the Ideal-X left Newark with cargo packed in containers rather than loose in its holds. What had taken more than a week to load could then be done in hours, and shipping costs fell.
Questions people ask
How big is a standard shipping container?
The most common boxes are 20 feet and 40 feet long, both 8 feet wide and about 8 and a half feet high. Shipping lines price and count capacity in 20-foot units, called TEUs, so a 40-foot box counts as two TEUs.
Why does keeping the box sealed matter so much?
Before containers, dockworkers loaded ships piece by piece, and cargo was handled many times along the way. That made shipping slow and expensive, and theft was common because goods were exposed at every transfer. A sealed box that moves intact removes most of that handling, delay, and loss.
Who pushed the container system into use?
American trucking owner Malcolm McLean developed the modern system in the 1950s, using a strong corrugated steel box built to stack and transfer between trucks and ships. He sold much of what he owned to buy a ship and build the system around that box.
