US Tariffs on Imports from Iran
Iran Import Tariff Overview
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's closure of the strait since early March 2026 and the US naval blockade announced April 12 affect ALL shipping through this critical chokepoint, regardless of origin or destination.
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 has caused Brent crude to surge from $61/bbl to over $118/bbl, with cascading effects on shipping costs, raw material prices, and import costs worldwide.
Key Products Imported from Iran
Direct imports from Iran are largely prohibited. The Hormuz disruption primarily affects crude oil, LNG, petrochemicals, aluminum, and fertilizers from Gulf states (Saudi Arabia, UAE, Kuwait, Qatar, Iraq, Bahrain). Rising oil prices also increase costs for petroleum-derived products (plastics, chemicals, synthetic textiles) manufactured anywhere in the world.
Recent Changes
February 28, 2026: US/Israel launch strikes on Iran. Iran effectively closes Strait of Hormuz. March 11: IEA releases 400M barrels from reserves. March 18: Qatar Ras Laffan LNG facility damaged. April 7: Two-week ceasefire announced but strait remains closed. April 12: Trump announces full US naval blockade of Hormuz.
Tips for Importers
The Hormuz crisis affects your imports even if you don't trade with Iran. Higher bunker fuel costs mean carrier surcharges on all ocean shipments. Petroleum-derived raw materials are more expensive at the factory level. Transit times from Asia to US East Coast are 10-15 days longer due to Cape of Good Hope rerouting. Review your cargo insurance for war risk exclusions. Build inventory buffers for critical components.
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.
