How much crude oil does the US get from Iran? A quick breakdown

In 2023, the United States imported roughly 150,000 barrels per day of crude oil from Iran—down from over 200,000 barrels per day just a few years earlier. That’s less than 2% of total U.S. oil imports, making Iran a minor supplier compared to Canada, Mexico, or Saudi Arabia. The drop reflects U.S. sanctions and shifting global trade patterns, but it also raises questions about energy security and alternative supply routes.

Where does the oil actually go?

Most of the crude oil that reaches the U.S. from Iran arrives indirectly, often through third countries like China or the United Arab Emirates. Sanctions imposed by the U.S. in 2018 effectively block direct imports, so any oil that arrives is technically “re-exported” rather than shipped straight from Iran. This makes tracking exact volumes tricky, but customs data and industry reports suggest the numbers remain small but persistent.

Why such low volumes?

Two main factors keep U.S. imports from Iran at a fraction of their 2010s peak. First, U.S. sanctions have made it illegal for American companies to buy Iranian oil without special waivers, which are rarely granted. Second, Iran’s oil exports have been redirected to other markets—especially China, India, and Syria—where demand remains strong despite international pressure. For U.S. refiners, switching suppliers is usually easier than navigating legal risks.

What does this mean for U.S. energy?

Even at low levels, every barrel counts when global markets tighten. The U.S. still imports about 6 to 7 million barrels per day of crude oil, so Iran’s contribution is negligible in the grand scheme. However, the symbolic weight matters: every barrel from Iran represents a crack in the sanctions regime and a potential loophole for future enforcement. For energy planners, the bigger concern is disruptions elsewhere—like Russia’s war in Ukraine or OPEC production cuts—rather than Iranian oil specifically.

Could imports rise again?

Unlikely in the near term. The Biden administration has maintained the core sanctions structure, and Iran’s oil exports are tied to broader geopolitical deals—not just energy economics. Any increase would likely require a major shift in U.S.-Iran relations or a new round of sanctions waivers, neither of which appears imminent. For now, U.S. refiners have adapted to life without Iranian crude, sourcing more from domestic shale, Canada, and Latin America.

Bottom line for energy buyers

If you’re tracking U.S. oil supplies, Iran isn’t the first place to look. Focus instead on OPEC+ production decisions, U.S. shale output, and pipeline capacity from Canada. Iranian oil remains a niche factor—one that’s more relevant for sanctions watchers than for day-to-day energy buyers. Still, in a volatile market, even small supply sources can become unexpectedly important.
