Authored by Dryad analyst **Scarlett Suarez**, the paper traces how sanctioned Iranian crude, Chinese buyers, and a growing “shadow fleet” are reshaping commercial risk across Asia and globally.   - **Sanctioned volumes remain high.** Iran exports an estimated **1.5–2.0 million bpd**, with **80–90%** heading to China—revenue that sustains proxy activity and procurement.  - **Aging tankers, higher incident risk.** A **~477-ship** shadow fleet—**~70%** of it **15+ years** old—moves much of this oil via AIS-dark legs and STS transfers.  - **Sanctions pressure vs. persistence.** Despite **19 rounds** of U.S. actions designating **250+ entities/vessels** in 2025, flows adapt via yuan payments, barter, front companies and paperwork fraud.  ### Complete this form to download your copy     ## **What’s new in this report**   **Direct oil-for-arms linkages.** The paper documents **October 2025** negotiations between IRGC/AFGS and Chinese firms (e.g., **Haokan**) that explicitly tie oil shipments to **missile/drone component** deliveries—escalating both compliance and security exposure for any vessel or counterparty touching these trades.  **Where the risk concentrates.** The analysis highlights deliveries into **Shandong “teapot” refineries** via terminals such as **Rizhao Shihua** and facilities around **Daya Bay** and **Dongying**, often after AIS-dark **STS** operations and origin relabelling (e.g., “Malaysian” crude).  **Governance erosion.** A parallel tanker “dark pool”—now **~10%** of global oil-tanker capacity—normalises non-compliance (AIS off, flags of convenience, falsified certs). That trend threatens to fragment maritime governance and increase spill, casualty and enforcement risk for legitimate actors.    ## **Why shipping should care now** - **Operational exposure:** Older hulls and frequent **STS** in busy sea lanes (South China Sea/Malacca approaches) increase collision and pollution risk—and associated uninsured liabilities.  - **Compliance complexity:** Fraudulent certifications and front-company networks raise the chance of **inadvertent sanctions breaches** for owners, charterers, financiers and insurers—even on seemingly routine legs.  - **Security knock-ons:** Persistent revenues fuel **proxy capabilities** (e.g., Houthis), driving route diversions, higher insurance/freight and wider supply-chain disruption.    ## **Who should read this** - **Owners & operators** screening voyages and counterparties - **Charterers & traders** managing origin risk and documentation chains - **P&I/insurers** assessing casualty, sanctions and ESG exposure - **Ports/terminals** refining pre-arrival checks and PSC posture ## **What you’ll take away** - A clear map of the **entities, ports and logistics** enabling the loop - Evidence of **AIS-dark tactics, STS hotspots, relabelling practices** - The latest on **sanctions rounds** and how evasion networks adapt - Practical implications for **due diligence, voyage screening, and audit trails**    **Metis Insights** is powered by real-time intelligence, human and AI-enhanced analysis, and global expertise, giving you the edge in maritime decision-making. 🛡️ Stay informed.
