Then came the Ping Shun.
A US-sanctioned Aframax tanker, carrying roughly 600,000 barrels of Iranian crude loaded from Kharg Island in early March, had spent days signalling Vadinar, Gujarat, as its destination. It was on course to dock at the Rosneft-backed Nayara Energy refinery — and it would have been India's first Iranian crude delivery since May 2019. Instead, the vessel made a sharp southward turn near Gujarat and started pointing its AIS transponder toward Dongying, China.
That one course correction made official statements and on-the-ground reality look very different.
Why India Stopped Buying Iranian Oil in the First Place
The backstory matters. Before 2018, Iran was a cornerstone supplier for India's refiners. At peak, Iran supplied roughly 11.5% of all Indian crude imports — around 518,000 barrels per day in 2018. Indian refiners specifically valued Iran's "Iran Light" and "Iran Heavy" grades for their competitive pricing and compatibility with domestic refining configurations.That changed when the US reimposed sweeping sanctions on Tehran. Washington offered temporary waivers allowing key buyers, including India, to continue purchasing Iranian crude during a transition period — but by May 2019, those waivers expired and were not renewed. India, unwilling to risk access to the US financial system, stopped Iranian oil imports entirely.
For nearly seven years, the trade relationship went dark.
What Changed in 2026: The War, the Waiver, and the Window
The conflict that erupted on February 28, 2026, when the United States and Israel launched a large-scale air offensive against Iran, fundamentally disrupted global energy supply chains. Iran's Supreme Leader Ayatollah Ali Khamenei was among the over 1,340 people killed. Tehran responded with drone and missile strikes targeting Israel, Jordan, Iraq, and Gulf states hosting US military assets. The Strait of Hormuz — through which a significant portion of the world's seaborne oil passes — was effectively choked, pushing prices sharply higher.India felt the squeeze hard. As the world's third-largest oil importer and consumer, the country sources nearly 50% of its energy needs from the Middle East, representing approximately $180 billion in annual imports as of 2024. With traditional supply lanes disrupted, New Delhi needed options.
Washington responded with a pragmatic, if temporary, measure: a 30-day sanctions waiver on Iranian oil and refined products already loaded onto vessels as of March 20, 2026. The window closes April 19. It was intended to relieve some of the pressure on global markets by allowing buyers to move stranded Iranian barrels.
India moved quickly — at least officially. The petroleum ministry's statement on April 4 was unambiguous: "Amid Middle East supply disruptions, Indian refiners have secured their crude oil requirements, including from Iran; and there is no payment hurdle for Iranian crude imports." The ministry reinforced that India's crude requirements are fully secured for the coming months and that its refiners retain flexibility to source from over 40 countries.
The government also confirmed that 44,000 metric tons of Iranian LPG had arrived aboard a sanctioned vessel at Mangaluru port, where it was actively being discharged.
The Ping Shun Problem: When a Tanker Tells a Different Story
While the ministry's statement was making rounds on X (formerly Twitter), ship-tracking firm Kpler was watching the Ping Shun complete a different kind of headline.The Aframax tanker, built in 2002 and placed under US sanctions in 2025 for its involvement in Iranian crude trade, had been signalling Vadinar as its destination for three consecutive days. With an estimated arrival of April 4 at Nayara Energy's 20-million-tonne-per-year refinery, it looked like the historic first delivery was imminent.
Then it wasn't.
The vessel pivoted mid-voyage, and its AIS transponder began pointing toward Dongying, a port in China's Shandong province. Commodity market analyst Sumit Ritolia of Kpler summarized the situation directly: the destination shift appeared to be payment-related, with Iranian sellers tightening their terms and moving away from 30-to-60-day credit windows toward upfront or near-term settlement demands.
That distinction is critical. Iran remains cut off from SWIFT — the global banking messaging network through which most international financial transactions are cleared — after being disconnected in 2012 following European Union sanctions. The previous workaround, which involved conducting transactions in euros through a Turkish bank, no longer exists. Indian state refiners, many of which rely on dollar-denominated transactions through Asian banks, have found that those financial institutions are declining to process payments tied to Iranian crude even under the temporary waiver, fearing long-term compliance risk.
The result: a 600,000-barrel cargo that may have been destined for India ended up heading to China, the one large buyer whose financial infrastructure has been specifically calibrated to handle exactly this kind of transaction.
Between Policy and Practice: India's Real Dilemma
This is not a situation unique to India. Iranian crude has remained heavily discounted compared to benchmark grades precisely because the pool of buyers willing and able to process the payments is limited. China has developed what amounts to a parallel financial infrastructure for this purpose — using yuan-denominated trades, alternative banking networks, and opaque intermediaries to absorb Iranian barrels that the rest of the world struggles to touch.India's state refiners — including Indian Oil Corporation and Bharat Petroleum — have historically been cautious about this territory because they rely on international banking relationships that could be jeopardized by sanctioned transactions. Private refiners like Reliance have more flexibility but have their own exposure to US capital markets.
What's clear is that the ministry's optimism about "no payment hurdle" reflects a policy aspiration more than a fully resolved operational reality. Indian companies do appear to be working through some of these channels — the LPG cargo at Mangaluru is real, and the government's statement is not without basis — but the Ping Shun episode shows that completing such transactions involves layers of commercial negotiation that can collapse at the final hour.
For India, the stakes are not abstract. The Essential Commodities Act has already been invoked to conduct thousands of raids against hoarding and black-market LPG sales. Domestic LPG cylinders that normally retail between Rs 900 and Rs 1,000 are reportedly being sold illegally for Rs 1,800 to Rs 2,500 in some localities. The pressure on the government to stabilize energy supply is intense.
What History Says — and What It Doesn't
Before 2019, India's reliance on Iran provided more than just volume. It provided pricing leverage. Iranian crude was competitively priced, and the credit terms Iran traditionally offered Indian refiners — 60-day windows, sometimes in rupees — gave Indian buyers cost advantages unavailable from other suppliers.Recreating those terms in the current environment, with Iran under SWIFT restrictions and US sanctions still technically active outside the 30-day window, is a fundamentally different challenge. Analysts note that while the waiver allowed the movement of barrels already loaded, it did not resolve the underlying payment infrastructure problem. And with the waiver expiring April 19, the clock is ticking.
If the Ping Shun's cargo does eventually reach an Indian refinery — which remains possible if payment terms are resolved — it would mark a genuine milestone. If it doesn't, it will serve as a reminder that energy diplomacy and tanker logistics are two very different things.
The Bigger Picture: India Balancing Washington and Tehran
India has long operated a careful balancing act in its foreign energy policy. It maintained oil imports from Russia even as Western nations applied pressure following the 2022 invasion of Ukraine, and it has consistently argued that its energy needs require pragmatism over political alignment. That approach has served New Delhi well — Russian crude now comprises a substantial share of Indian imports at deeply discounted prices.The Iran question is trickier. Unlike Russia, which has its own financial workarounds and can transact in rupees and dirhams, Iran's banking isolation is far more severe. And unlike the Russia situation, where the US eventually accepted India's position, any large-scale resumption of Iranian crude imports could directly test India's relationship with Washington at a time when the broader US-Iran conflict is still actively unfolding.
India's government is threading that needle carefully — confirming purchases without committing to scale, citing commercial flexibility while watching how far the waiver window takes them.
