A container may leave a British port carrying perfectly good machinery, food or components, yet the exporter can still lose money long before it reaches its destination. The disciplines involved in international trade extend far beyond finding a customer and arranging transport. They determine whether the seller is paid, whether the goods clear customs, whether the contract means what both parties think it means, and whether a promising overseas relationship survives its first difficulty.
That is why international trade has never been a single profession. It is a meeting place for commercial judgement, law, banking, transport, technical knowledge and human understanding. Digital systems have altered the speed of communication, but they have not removed the underlying risks. Indeed, a quicker transaction can expose poor preparation more rapidly.
