One year after US President Donald Trump returned to the White House and revived the "maximum pressure" sanctions on Iran from his first term, available data show the country’s energy exports remain largely intact.

Data from the commodity intelligence firm Kpler, seen by Iran International, show that in 2025 Iran delivered an average of 1.38 million barrels per day (bpd) of crude oil and gas condensate to China—a decline of just 7 percent compared with 2024.

After Iranian oil exports to Syria halted in December 2024, China effectively remained Tehran’s sole buyer of crude oil over the past year.

Unlike crude oil, Iran’s petroleum product exports—fuel oil (mazut), naphtha and liquefied petroleum gas (LPG)—are relatively diversified, with shipments mainly destined for China, the United Arab Emirates, Malaysia and Singapore.

According to Kpler, Iran exported an average of 190,000 bpd of naphtha and 256,000 bpd of fuel oil last year, a combined decline of about 13 percent compared with 2024.

The drop, however, was driven not by tighter US sanctions but by Iran’s worsening domestic gas shortages, which forced power plants and industrial facilities to burn more fuel oil, reducing volumes available for export.

Data from tanker-tracking firms Kpler and Vortexa show that the modest decline in crude oil exports was offset by increased shipments of natural gas and LPG.

Iran has also continued exporting natural gas to Turkey and Iraq.

Tehran and Baghdad don’t publish official figures, but data from Turkey’s energy ministry indicate that natural gas imports from Iran increased about 9 percent during the first 11 months of last year compared with the same period in 2024.

One reason US sanctions have struggled to significantly curb Iran’s energy exports has been the continued operation of the so-called shadow fleet—a network of oil tankers that transport sanctioned crude through flag changes, disabled tracking systems, ship-to-ship transfers, and opaque ownership structures.

According to estimates by TankerTrackers, roughly 1,500 oil tankers worldwide were involved in shadow fleet activity last year, with nearly 40 percent linked to Iranian oil shipments.
