LONDON, August 20, 2025 — Ships are still sailing, containers are still moving, but the patterns are broken. New trade tariffs imposed this summer have forced freight companies to redraw their maps almost overnight.

In the U.S., cargo that used to head straight to Los Angeles is now landing in Mexico before crossing north by truck. Canadian ports are seeing similar surges. In Europe, importers of electronics and machinery are rerouting to southern gateways, avoiding the duties that hit traditional northern hubs.

Forwarders describe the change as chaotic. “We planned for volatility,” said a Hamburg operator, “but not for this speed of disruption. One week you think you’ve solved it, the next week the rules change again.”

The side effects are clear. Spot prices on secondary routes are climbing fast. Warehouses near free-trade zones are crammed with goods that were rerouted mid-voyage. Smaller exporters, without the resources to improvise, are holding shipments back altogether.

Analysts don’t expect the situation to calm quickly. They warn of longer transit times, higher insurance costs, and supply chains stretched to breaking point. Governments call tariffs a tool for protecting local industry. On the ground, logistics workers call them something else: another fire to put out in a year already full of them.
