## What it is

Iran's oil sanctions-evasion system is a layered network of aging tankers, shell companies, and commodity brokers that allows Iran to sell crude oil on global markets despite comprehensive US and EU sanctions. The core mechanism works in stages: tankers load Iranian crude at Persian Gulf terminals under falsified paperwork showing a third-country origin; they transit to international waters for ship-to-ship transfers that blur the cargo's paper trail; the oil arrives at Chinese refineries documented as Malaysian, Iraqi, or Omani blend. The main Iranian state actor is the National Iranian Oil Company (NIOC), which coordinates export logistics. The primary buyers are independent Chinese refineries concentrated in Shandong province, commonly called "teapot" refiners, which absorb an estimated 90% of Iranian oil exports. Intermediaries, typically UAE-registered, Hong Kong-registered, or Singapore-registered shell companies, manage vessel charters and payment routing.

## History

US restrictions on Iran's oil sector date to 1995, when the Clinton administration barred US firms from Iranian energy investment. The UN Security Council imposed multilateral measures from 2006 onward following Iran's nuclear escalations. EU oil sanctions took effect in July 2012, cutting Iranian crude exports from roughly 2.5 million barrels per day to approximately 1 million bpd. The 2015 Joint Comprehensive Plan of Action (JCPOA) suspended nuclear-linked oil sanctions; Iran's exports recovered to around 2.3 million bpd by late 2017. In May 2018, the Trump administration withdrew from the JCPOA and reimposed full sanctions under a "maximum pressure" policy. Iranian exports collapsed to roughly 300,000-400,000 bpd by late 2019, the lowest level since the 1980s Iran-Iraq War. From 2021, under the Biden administration's less aggressive enforcement posture, Iran rebuilt exports using an expanding shadow fleet, reaching approximately 1.3-1.5 million bpd by 2023 and 1.5-1.7 million bpd by 2025.

## Current state

As of early 2026, Iran was shipping approximately 1.5-1.7 million barrels per day through the shadow network. China absorbed roughly 90% of those exports, with the bulk landing at Shandong teapot refineries that accept discounted sanctioned crude unavailable to larger, compliance-constrained buyers. By late 2025, more than 60% of vessels that had loaded Iranian crude in the prior 12 months carried OFAC designations, up from 38% a year earlier. The Trump administration, returning to office in January 2025, sanctioned over 180 vessels within its first 13 months. In October 2025, the US Treasury designated over 50 individuals, entities, and vessels, including a China-based crude oil terminal and a named Chinese refinery. In December 2025, Treasury sanctioned 29 additional shadow-fleet vessels and their management firms. In February 2026, the State Department identified a further 14 vessels as blocked property. The [June 2026 LPG action](/ar/n/iran-lpg-shadow-banking-sanctions-2026) extended this pattern to liquefied petroleum gas, targeting UAE and China front companies that relabelled Iranian LPG as Omani. Because sanctioned tankers face sharply higher insurance costs and vessel managers demand higher commissions, Iran has absorbed an estimated price discount of US$5-10 per barrel below Brent on each sanctioned cargo. From May 2026, an intensified US naval enforcement campaign significantly curtailed export volumes.

## Relationships

Iran's crude revenues fund the state budget directly and finance the Islamic Revolutionary Guard Corps (IRGC) indirectly through NIOC dividend flows and parallel IRGC-linked trading networks. The nuclear dispute is inseparable from the sanctions architecture: any progress toward a nuclear framework, as tracked in [Iran, Islamic Republic](/ar/n/iran-dossier), typically opens discussions of phased [الولايات المتحدة تُصدر استثناءً من عقوبات النفط الإيراني لمدة 60 يوماً](/ar/n/iran-oil-sanctions-relief), while diplomatic breakdowns accelerate OFAC designations. The shadow fleet depends on a parallel financial layer: payments route through UAE and Hong Kong accounts, with an increasing use of Chinese yuan settlement and cryptocurrency conversion to bypass US dollar clearing. North Korea operates a structurally comparable evasion architecture for coal and petroleum, with overlapping flag registries and vessel management firms, as seen in [North Korea's oil and coal shadow fleet runs on as the MSMT replaces the UN panel](/ar/n/north-korea-maritime-oil-evasion-2026).

## What to watch

Whether Chinese authorities tighten controls on Shandong teapot refineries will be the primary determinant of how much Iranian export volume survives US enforcement pressure. Any new nuclear framework would unwind shadow-fleet arrangements rapidly, since buyers prefer on-market crude at unencumbered prices and vessel managers prefer clean compliance records. The proliferation of AI-assisted vessel-tracking platforms at Kpler, Vortexa, and Lloyd's of London is shortening the lag between evasion and designation, making earlier ghost-fleet tactics, such as simple transponder disabling, increasingly costly and detectable.
