The tanker Ping Shun, sanctioned by the US, was initially en route to Vadinar port in Gujarat, India, carrying about 600,000 barrels of Iranian crude oil, marking the first Indian purchase since 2019. However, it has now rerouted to Dongying, China, due to payment-related issues. According to Sumit Ritolia, a Lead Research Analyst at Kpler, the shift indicates tightening payment terms from sellers, moving from a 30-60 day credit window to upfront payments. This change in destination underscores the sensitivity of trade flows to financial terms amid US sanctions. In mid-March, the US eased sanctions temporarily, allowing the sale of about 140 million barrels of Iranian oil, which has implications for countries like India that were major buyers prior to the sanctions. The rerouting of Ping Shun could reflect broader challenges in Iranian oil sales, particularly as Tehran remains cut off from the SWIFT banking system, complicating payment processes.
