China’s Record US Ethane Imports Surge Amid Iran War Supply Disruptions China is set to import a record volume of US ethane in April 2026, driven by war-induced supply chain disruptions in the Middle East that have choked off traditional petrochemical feedstocks. According to industry analysts and trade data, shipments of US ethane are expected to reach an all-time high of 800,000 tons this month—approximately 60 percent above the monthly average—as Chinese manufacturers seek reliable alternatives to naphtha and liquefied petroleum gas (LPG) from the Persian Gulf. The surge follows the escalation of the Iran war in late February 2026, which led to the effective closure of the Strait of Hormuz, a critical maritime chokepoint for energy and chemical shipments bound for Asia. Prior to the conflict, Persian Gulf nations supplied more than half of China’s naphtha imports and about 40 percent of its LPG purchases. With those flows severely disrupted, petrochemical producers across China have rapidly pivoted to ethane as a substitute feedstock for ethylene production, a key building block in plastics manufacturing. Ethane, a natural gas liquid primarily used to produce ethylene, has become the preferred alternative for Chinese ethylene makers due to its stable supply and cost advantages. Analysts at JLC, a Chinese energy consultancy, noted that profits from producing ethylene using ethane were tenfold those from naphtha as of mid-April 2026, a disparity amplified by crude-linked pricing that has inflated naphtha costs. This economic incentive, combined with supply necessity, has accelerated the shift toward US-sourced ethane. China’s dependence on the United States for ethane is nearly total, making US exports a vital lifeline for its manufacturing sector during the crisis. The product previously became a flashpoint in Sino-US trade relations when Washington tightened export controls during a period of heightened tensions. However, current market dynamics have reversed that stance, with US ethane now serving as a stabilizing factor in China’s industrial supply chain. The record imports coincide with broader diplomatic engagement, as US officials prepare for an anticipated high-level visit to Beijing in mid-May 2026, where energy security is expected to feature prominently on the agenda. Analysts observe that while the reliance on a single supplier introduces strategic vulnerability, the immediate availability and reliability of US ethane have proven essential in mitigating production halts across China’s petrochemical industry. As downstream production capacity continues to expand, demand for ethane is projected to remain elevated, reinforcing the United States’ role as a critical supplier of niche energy feedstocks to global markets. For now, the surge in US ethane imports stands as a direct consequence of geopolitical disruption—and a testament to the speed with which global supply chains can adapt under pressure.
