Recent investigations reveal a sophisticated network funneling Russian petroleum products through Moroccan ports, circumventing Western sanctions imposed following the Ukraine conflict. The North African kingdom has emerged as a critical transit hub, enabling Moscow to reach markets officially closed to its energy exports.

Geneva-based trader orchestrates covert oil shipments

Morocco solidified its role in 2025 as North Africa’s largest importer of Russian fuel, a position facilitated by Alvari SA, a discreet Geneva-based trading firm. The company orchestrated multimillion-dollar deliveries using vessels like Tranquil Sea, Duke II, and Eldia, which transported Russian petroleum products from Baltic terminals to Moroccan ports including Jorf Lasfar and Mohammedia.

The Tranquil Sea case exemplifies the evasion tactics employed. British sanctions lists included the vessel by October 2025 as it approached Moroccan waters, followed by EU and Swiss sanctions. Ukrainian defense authorities allege the ship previously served as a surveillance platform targeting NATO military and aerial operations, while Finnish authorities detained it on suspicion of damaging an undersea cable. Alvari SA, contacted for comment, denied any direct or indirect involvement in chartering or operating these ships through its legal representatives.

False origins: Turkmenistan labels mask Russian fuel

To obscure the true source of deliveries, Cypriot chambers of commerce issued certificates of origin falsely attributing diesel shipments to Turkmenistan. These operations occurred during at-sea transshipments near Gibraltar under Off Port Limits (OPL) protocols, which are typically reserved for minor logistical tasks rather than high-risk fuel transfers.

Financial records show dollar-denominated transactions between Morocco’s Attijariwafa Bank—controlled by the royal holding Al Mada—and the Tangier-based offshore branch of the Popular Central Bank acting as supplier. Moroccan distributors reportedly secured discounts of approximately seven dollars per metric ton compared to European benchmarks, while non-Russian products traded 15 dollars above these indices, yielding total savings of around 22 dollars per ton. These cost advantages were not passed on to consumers at the pump.

The diplomatic dimension adds further complexity. As Tranquil Sea approached Moroccan shores, Foreign Minister Nasser Bourita traveled to Moscow for high-level talks with Sergei Lavrov. Days later, during a critical UN Security Council vote on Western Sahara, Russia abstained—a decision favorable to Rabat’s interests.

Spain raises alarms over potential EU rerouting

Spanish media has documented a parallel concern: a surge in diesel imports from Morocco. Industry sources suspect Russian fuel may be entering the European Union through Moroccan ports, exploiting the North African country’s lack of refining capacity. Data from Kpler indicates Moroccan imports of Russian diesel reached 645,000 tons in 2025, climbing to 489,000 tons in early 2026—constituting 45% of total Moroccan fuel imports. Notably, Morocco exported no diesel to Spain before the 2022 Ukraine war and subsequent EU sanctions.

This revival coincides with escalating Middle East tensions and the closure of the Strait of Hormuz. Spanish strategic reserves data show 76,000 tons of Moroccan-origin diesel arriving in Spanish ports including Tarragona, Barcelona, and Bilbao between April and June 2026—after nearly a year of negligible flows. Spanish refiners, represented by the Spanish Fuel Industry Association (AICE), have expressed concerns over unfair competition from potentially illicit fuel sources.

Converging investigations reveal shadow trade routes

Together, these reports trace a suspected route: Russian oil products rebranded en route, transiting Morocco before potentially entering the European Union. While neither investigation claims definitive proof of every shipment following this exact path, both rely on strong circumstantial evidence including maritime tracking data (Kpler), customs documents, and industry testimonies. Proving the precise origin of refined products once blended into global supply chains remains structurally challenging.
