Chinese dual‑use exports to Iran surge after U.S. sea blockade, customs data show

Iranian customs data reviewed by The Wall Street Journal indicate about 1,300 shipments from Chinese suppliers to Iran’s Defense Ministry in the first half of the year, including electronics, motors, GPS gear and aircraft parts that can be used in drones and missiles. The flow picked up after U.S. moves to curb Iranian sea trade.

A sharp rise in Chinese dual‑use exports to Iran’s Defense Ministry is drawing attention to how Tehran is reconfiguring its procurement networks under U.S. pressure.

The Wall Street Journal reports that Iranian customs data show about 1,300 shipments from Chinese suppliers to entities tied to Iran’s Defense Ministry through June this year. The shipments included electronics, motors, GPS equipment and aircraft parts that can be used in drones and missiles.

According to the report, those deliveries accelerated after the United States moved to blockade Iranian sea trade, making it harder for Iran to export oil and import sensitive goods by ship. As maritime routes came under more strain, sanctioned Iranian airline Mahan Air sharply increased its cargo flights, shifting more of the supply chain into the air.

For countries already facing Iranian‑supplied drones and missiles, the nature of these components is worrying. Items such as electric motors and navigation systems can be built into loitering munitions, cruise missiles and long‑range drones that can reach airfields, energy sites and cities far from Iran’s borders.

The shipments sit in a legally grey area. Many of the listed goods have civilian as well as military uses. But their scale and their reported destination—the Defense Ministry—are likely to fuel calls in Washington and European capitals for tighter scrutiny of Chinese firms and intermediaries.

For Iran, turning to Chinese suppliers and to air cargo is a way to keep its defense industry supplied despite sanctions. Years of restrictions have already forced Iranian engineers to improvise and reverse‑engineer foreign technology. Chinese parts help fill remaining gaps and support weapons programs that Tehran uses both at home and through partners across the region.

The move from ship to air also creates new vulnerabilities. Air freight is easier to track through flight data and airport records, even if it is harder to intercept in transit. Western intelligence agencies are likely to watch Mahan Air’s routes and cargo patterns closely for signs of where and how these components move.

Next signals to watch include any public response from Beijing to the customs data, potential U.S. or EU steps to blacklist specific Chinese companies involved, and changes in Mahan Air’s flight volumes and destinations that might indicate either growing confidence or rising pressure on this supply line.
