NEW YORK —U.S. prosecutors are investigating whether companies linked to Indian billionaire Gautam Adani imported liquefied petroleum gas (LPG) from Iran into India via the Adani-operated Mundra Port, The Wall Street Journal (WSJ) reported on Monday.

According to the report, several tankers traveling between the Mundra Port in Gujarat and the Persian Gulf showed patterns typically associated with sanctions evasion. Experts cited by the WSJ noted that the ships in question exhibited behavior consistent with attempts to obscure their origins or destinations—tactics often employed to bypass international sanctions.

The U.S. Department of Justice (DOJ) is said to be examining the operations of specific LPG tankers that delivered shipments to Adani Enterprises, people familiar with the matter told the Journal. However, Reuters has not independently verified the report, and neither the DOJ nor the U.S. Attorney’s Office in Brooklyn responded to requests for comment.

In a statement to the WSJ, a spokesperson for the Adani Group firmly denied any wrongdoing:

“Adani categorically denies any deliberate engagement in sanctions evasion or trade involving Iranian-origin LPG. Furthermore, we are not aware of any investigation by U.S. authorities on this subject.”

The latest development comes against the backdrop of stringent U.S. sanctions prohibiting the purchase of Iranian oil and petrochemical products. Under a 2019 directive issued by then-President Donald Trump, any individuals or entities engaging in such trade could be subject to secondary sanctions.

This scrutiny also follows earlier allegations against Gautam Adani and his nephew, Sagar Adani, involving bribery to secure power supply contracts and allegedly misleading U.S. investors during fundraising efforts. The Adani Group has described those accusations as “baseless” and said it would pursue “all possible legal recourse.”
