US efforts to curtail Iran's LPG exports may prove fruitless as Tehran's key trade with China is independent of the sanctioned firms, writes Ieva Paldaviciute
The US Treasury Department has for the first time imposed sanctions directly targeting Iran's LPG industry, as it looks to exert pressure on a sector involved in significant exports to China.
The US Treasury on 22 April announced sanctions on Iranian "LPG magnate" Seyed Asadoollah Emamjomeh, his son Meisam Emamjomeh, and his corporate network, which is "collectively responsible for shipping hundreds of millions of dollars worth of Iranian LPG and crude oil to foreign markets". This includes Emamjomeh's Tinos I — a 93,000m³ (55,000t) VLGC built in China in 2024, which allegedly attempted to load LPG from a terminal in Houston for export to China on its maiden voyage in June 2024.
Washington recognises that Iran's LPG industry is a major source of revenue for Tehran, funding the regime's nuclear and advanced conventional weapons programmes and its support for terrorist proxies in the Middle East. The US administration continues to impose new sanctions on Iran despite both sides attempting to ease tensions as they hold high-level talks on Iran's nuclear programme, after US president Donald Trump ordered his administration to exert "maximum pressure" on Tehran.
Yet the sanctions' impact on LPG trade may prove limited. "The nature of [Iran's LPG trade with China] is independent of Emamjomeh or his son and will continue pretty much as is," consultancy FGE's Middle East managing director Iman Nasseri says. "Sanctioning these companies only adds extra costs to the middlemen, who switch to other companies that they have or will set up, while changing the name or ownership of a vessel is also very easy."
Iran's LPG exports boomed during 2022-24, largely owing to less-stringent sanctions under former US president Joe Biden. China is the dominant buyer of Iranian LPG, taking 8.3mn t of the 10.7mn t exported from Iran in 2024, Kpler data show. This figure is an estimate as tracking Iran's exports is complicated by its use of a "shadow fleet" of LPG carriers.
"The illicit [Iranian LPG] network has many nodes, and it is more difficult to choke them all off, especially if the US is wary of undermining other trade with countries such as the UAE, Oman, Malaysia and others [that receive Iran's LPG]," US think-tank the Center for a New American Security's adjunct senior fellow Rachel Ziemba says. "At the same time, the US could now be less worried about undermining relationships with China as direct US-China trade is collapsing."
China's imports of US LPG, mainly propane, are on course to end from mid-May when Bejing's 125pc tariff kicks in. China is considering exemptions for ethane. But there has been no indication that US propane will also be given a reprieve, according to market participants — in spite of the Chinese petrochemical sector's dependence on it. China is increasingly turning to the Middle East for supplies, but these shipments largely come with butane in split cargoes.
