How the shipping container changed world trade

This piece for HubCage collects the advice that holds up in practice.

Before standard containers, cargo was loaded onto ships piece by piece, a slow process that could keep a vessel in port for a week or more. The steel box of standard dimensions changed that. Containers move directly between ships, trains and lorries without being unpacked, so loading that once took days now takes hours and goods suffer far less damage or theft.

Standardisation is the real innovation. Because every port, crane and trailer is built around the same sizes, a container can travel across continents with little handling. That efficiency lowered transport costs so much that it reshaped where things are manufactured. It also means a disruption at a single major port can ripple through supply chains worldwide.
