Iran is under comprehensive US sanctions. Most imports from Iran are prohibited under OFAC regulations. The primary relevance for US importers is the Strait of Hormuz crisis — Iran closed the strait from late February 2026 through April 17, 2026, when it reopened after a US naval blockade. The event affected ALL shipping through this critical chokepoint during the closure.
US-Iran trade is virtually nonexistent due to comprehensive sanctions. However, the Strait of Hormuz, which Iran borders, normally handles approximately 20% of the world's seaborne oil trade (~20 million barrels per day). The US-Iran military conflict that began February 28, 2026 and Iran's subsequent closure of the strait caused Brent crude to surge from $61/bbl to a peak of over $118/bbl during the closure. As of April 17, 2026, the strait has reopened and Brent has dropped to approximately $83/bbl, with shipping costs and raw material prices expected to begin easing.
Key Products Imported from Iran
Direct imports from Iran are largely prohibited. The Hormuz disruption primarily affected crude oil, LNG, petrochemicals, aluminum, and fertilizers from Gulf states (Saudi Arabia, UAE, Kuwait, Qatar, Iraq, Bahrain). The oil price spike also increased costs for petroleum-derived products (plastics, chemicals, synthetic textiles) manufactured worldwide; with the strait reopened, those feedstock costs should ease.
Recent Changes

April 7: Two-week ceasefire announced but strait remains closed. April 12: Trump announces full US naval blockade of Hormuz. April 15: Blockade declared 'fully implemented.' April 17: Iran reopens the strait; Brent crude drops from peak of $118/bbl to approximately $83/bbl.
Tips for Importers
The Hormuz crisis affected your imports even if you don't trade with Iran. During the closure, higher bunker fuel costs meant carrier surcharges on all ocean shipments, petroleum-derived raw materials were more expensive at the factory level, and transit times from Asia to US East Coast were 10-15 days longer due to Cape of Good Hope rerouting. With the strait reopened on April 17, 2026, these cost pressures should begin easing — renegotiate freight rates with your forwarders, check war risk insurance for potential premium adjustments, and request updated FOB quotes on petroleum-derived goods.
How US Tariffs on Iran Work
US import duties on goods from Iran are determined by multiple overlapping tariff authorities. The base layer is the Section 122 tariff at 10%, which applies to all countries and is set to expire around July 24, 2026. Section 232 tariffs of 50% on steel and 50% on aluminum apply to metals imports, regardless of the Section 122 rate.
