Direct trade between Iran and the United States has been severely restricted for decades due to comprehensive sanctions regimes. However, limited humanitarian trade channels do exist under specific licensing frameworks.
Under U.S. Treasury Department licenses (particularly OFAC General Licenses and specific waivers), Iran may import:
Payment Channels: Transactions typically route through sanctioned-country humanitarian mechanisms—often involving European banks with specific OFAC licenses or the Swiss Humanitarian Trade Arrangement (SHTA) established in 2020.
Volume Reality: Actual import volumes remain minimal—hundreds of millions annually versus billions in pre-sanctions eras. Most "U.S.-origin" goods reach Iran via third-country re-exports rather than direct shipment.
Geopolitical Volatility: License availability shifts with nuclear negotiations (JCPOA talks), regional tensions, and U.S. administration policies. What's permitted one year may be restricted the next.
Virtually all other categories—energy technology, industrial machinery, consumer goods, financial services, dual-use items—remain prohibited. Iran sources these from China, EU, UAE, Turkey, and other partners.
For current specifics, consult the U.S. Treasury OFAC sanctions guidelines and Iran's Trade Promotion Organization, as regulations evolve rapidly.
