Iranian oil tanker diverts from India to China amid 'payment uncertainty'

An oil tanker, carrying Iranian crude, initially bound for India, has rerouted mid-voyage to China. If the USD-sanctioned tanker had continued on its original route, it would have marked the first such shipment of Iranian crude in nearly seven years.

The Aframax tanker Ping Shun, built in 2002 and sanctioned by the US in 2025, is currently signalling Dongying in China as its destination instead of the earlier Vadinar in Gujarat, stated ship-tracking firm Kpler.

No official confirmation

However, there is no official confirmation that the destination that the ship's Automatic Identification System (AIS) transponder - a tracking system mandated on most commercial vessels - is indicating is the final, and it may not change at any time during the transit.

"An Iranian crude vessel 'Ping Shun' that had been en route to Vadinar, India, over the past three days has dropped India as its declared destination near arrival and is now signalling China," said Sumit Ritolia, Lead Research Analyst, Refining and Modelling at commodity market analytic firm Kpler.

Settlement constraints?

Any crude aboard the Aframax tanker Ping Shun would have marked India’s first Iranian oil intake since 2019, reopening a trade corridor dormant since sanctions tightened. Indian refiners had recently begun exploring whether a few cargoes already at sea could be secured under a temporary US waiver.

The vessel’s apparent diversion suggests the constraint lies less with shipping than with settlement. According to Ritolia, the shift in destination points to tougher payment expectations, with sellers moving away from the earlier 30- 60 day credit window toward quicker settlement. The counterparties involved in the transaction remain unclear.

Vadinar, the tanker’s earlier destination, hosts a 20 million tonne-per-year refinery operated by Rosneft-backed Nayara Energy, a facility that previously processed Iranian grades.

Trade sensitivity

"While such mid-voyage destination changes are not unprecedented with Iranian crudes, they highlight the increasing sensitivity of trade flows to financial terms and counterparty risk," he said.

"If the payment issues are resolved, the cargo could still make its way to an Indian refinery. However, the episode underscores how commercial terms are becoming as critical as logistics in determining Iranian crude flows to other countries apart from China."

Policy and past trends

New Delhi has maintained that any decision to resume imports will hinge on techno-commercial viability.

Iran once held a notable share in India’s crude basket, with imports ceasing in May 2019 after US sanctions tightened. Prior to that, volumes had already fallen sharply and have not resumed since.

Despite the current waiver allowing limited transactions involving oil at sea, payment channels remain uncertain, with Iran still outside the SWIFT network and earlier workaround mechanisms no longer in place.
