US Iran Sanctions: Operation Economic Outcast Targets Trade Network

Iran's Top Export Partners

Official customs figures, which exclude the unrecorded flows sustaining much of Iran's oil exports, reveal a heavily concentrated export base. China was Iran's largest buyer in 2024 at $14.58 billion, taking more than 80 percent of Iran's seaborne crude exports according to tanker-tracking analysts. Much of that oil is discounted and moved by shadow-fleet vessels, barely registering in either country's customs records.

Iraq ranked second at $11.7 billion, relying on Iranian gas for electricity generation and receiving direct electricity sales to southern provinces, along with food products, building materials and manufactured goods. The United Arab Emirates accounted for $7.16 billion, or 13 percent of Iran's exports, serving as a financial and re-export lifeline. Abu Dhabi imposed an indefinite trade embargo last week after accusing Iran of firing missiles at its territory, allegations Tehran has denied.

Turkiye received $6.1 billion in Iranian exports, including pipeline gas via the Tabriz-Ankara Pipeline, petrochemicals, food products and construction materials. Afghanistan followed at $2.3 billion, depending heavily on Iranian fuel, food, construction materials, ports and overland routes to reach wider markets.

Trade Data and Import Dependencies

The official customs figures compiled by Trade Data Monitor provide the clearest available picture of Iran's commercial relationships, though they exclude the shadow flows that sustain much of its oil exports. This limitation means the true scale of Iran's trade, particularly in energy, is likely higher than recorded figures suggest.

China's dominance is especially notable given that discounted Iranian crude moved by shadow-fleet vessels barely appears in either country's official customs records, underscoring the challenge Washington faces in enforcing sanctions against flows that already operate largely outside formal reporting channels.

What Happens Next

Bessent did not name specific countries or set a deadline for the diplomatic outreach, leaving the timeline and scope of enforcement uncertain. The effectiveness of Operation Economic Outcast will depend on whether Washington can persuade Iran's major partners, particularly China, Iraq, the UAE and Turkiye, to curtail their commercial ties.

Further details on the designated entities and any responses from Iran's trading partners have not yet been officially confirmed.
