Diesel, Tariffs And War: The Perfect Storm Battering U.S. Shipping

The U.S. shipping and freight industry is navigating one of its most turbulent periods in recent memory, squeezed simultaneously by surging fuel costs, an escalating tariff regime, and the knock-on effects of conflict in the Middle East.

Diesel prices have surged past $5.40 per gallon nationally, with California approaching $7.22 per gallon — a level that is distorting transportation economics across the entire western supply chain. The spike is cascading across every mode of freight movement. Amazon has introduced a new fulfilment surcharge of 3.5 percent on its FBA services, pushing per-unit costs higher for sellers as the e-commerce giant passes through elevated fuel and logistics expenses.

For small and mid-sized shippers, the arithmetic is brutal. Escalating surcharges across parcel and fulfilment networks are forcing them to absorb rapidly rising costs with little ability to push back.

The pain is not confined to trucks. The closure of the Strait of Hormuz has cut off a major source of global resin supply, rattling trans-Atlantic container trades and creating fresh procurement headaches for U.S. manufacturers. Major ocean carriers including CMA CGM, Hapag-Lloyd, and Maersk have been seeking emergency surcharges to recover war-driven cost increases — though regulators have been applying the brakes on rapid implementation.

Surging jet fuel prices are simultaneously compressing air cargo margins and reducing viable freighter capacity, increasing the risk of higher rates and constrained lift for time-sensitive shipments.

The tariff picture adds yet another layer of complexity. Revised U.S. metal tariffs now impose tiered rates based on product composition, creating additional sourcing headaches for importers already navigating an unpredictable trade environment.

With no swift resolution to the Iran conflict in sight and trade policy remaining in flux, logistics executives are warning that the industry has entered an extended period of structural disruption — one that will reward only those shippers nimble enough to redesign their networks on the fly.
