The Strait of Hormuz may be thousands of miles from a U.S. warehouse, but the conflict surrounding this critical waterway can still show up on an importer’s freight invoice, fuel bill, and landed cost. Recent events are demonstrating just how quickly a regional conflict can become a global supply chain problem.
For U.S. importers, understanding that connection is becoming increasingly important.
ITC Diligence exists to bring clarity to importers and exporters around these complex market dynamics and how it affects their business.
Why Does the Strait of Hormuz Matter to U.S. Importers?
The answer starts with energy. Roughly 20% of global oil and LNG supply has historically moved through this narrow passage connecting the Persian Gulf with the Arabian Sea.
As conflict involving Iran has intensified, commercial shipping has faced growing uncertainty. On September 9, Reuters reported that only six commodity vessels passed through the waterway the previous day, compared with a 10-day average of 12. Brent crude also climbed above $100 per barrel as attacks on shipping and energy infrastructure raised concerns about supply.
An importer doesn’t need to purchase goods from the Middle East to feel that pressure.
The Cost Travels Far Beyond the Gulf
Think of global shipping like a highway network. Close one major bridge and traffic doesn’t simply disappear. Vehicles reroute, nearby roads become crowded, fuel consumption increases, and delivery times become less predictable.
Ocean freight works much the same way.
Current conditions are adding costs through:
- Higher marine insurance and war-risk premiums
- Emergency carrier surcharges
- More expensive bunker fuel
- Vessel rerouting and schedule changes
- Equipment and capacity imbalances
Reuters reported September 9 that insurance and war-risk expenses for some oil cargoes transiting the region have climbed dramatically. Maersk, meanwhile, announced emergency freight charges reaching $3,800 for certain containers moving through affected Upper Gulf markets, plus an additional $1,000 per container for vessels transiting the waterway.
Those are direct examples of global shipping costs reacting to geopolitical risk.
How Does That Reach a U.S. Importer?
The ripple effect is not limited to companies sourcing from Dubai, Saudi Arabia, or neighboring markets.
Higher oil prices can influence vessel operating expenses, trucking, airfreight, manufacturing, and inland transportation. At the same time, rerouting vessels changes capacity elsewhere in the network.
That means a company importing from Asia could encounter higher transportation costs even when its cargo never travels near the conflict.
This is how supply chain disruption becomes a landed-cost problem.
Build Flexibility Before the Next Headline
Importers cannot predict the next military escalation or shipping restriction. They can examine supplier concentration, routing alternatives, inventory levels, tariff exposure, and customs strategies before disruption forces a decision.
At ITC Diligence International, we connect customs planning with the realities of international logistics, giving companies greater visibility into where risk is building across the supply chain.
