The shipment arrived in Havana in December and is part of a series of hydrocarbon shipments documented in recent months to the island.
MADRID, Spain.- A ship from Mexico with approximately 14 million liters of fuel arrived at the port of Havana on December 23, 2025, in one of the most recent energy shipments made by Petróleos Mexicanos (Pemex) to Cuba, according to a research published by Mexican media based on foreign trade data and satellite monitoring of vessels.
The ship, identified as Ocean Mariner and under the flag of Liberia, it set sail from the Coatzacoalcos terminal, in the state of Veracruz, and transported a volume equivalent to more than 86,000 barrels of fuel. The shipment occurred in the middle of the Christmas season and was documented by the organization Mexicans Against Corruption and Impunity (MCCI), whose records served as the basis for journalistic reports.
According to the research, This shipment does not constitute an isolated event. During the months of November and December 2025, Mexico would have carried out several hydrocarbon exports destined for Cuba, some of them consigned to Cuban state companies. In official foreign trade records, for example, exports of automotive diesel worth more than 14 million dollars are reported.
He Ocean Mariner It has made multiple journeys between Mexican and Cuban ports throughout 2025, with stopovers in Havana, Cienfuegos and Moa, according to the tracking data cited. On January 5, 2026, the same vessel set sail again from Mexico bound for the Cuban capital, which would mark the first shipment of this type in the new year.
So far, Cuban authorities have not offered detailed public information on the commercial conditions of these shipments or their impact on the national energy system, marked by prolonged blackouts and fuel deficits.
In this context, the Mexican President Claudia Sheinbaum He assured this Wednesday that his country is not sending to Cuba “more oil than has been sent historically” and that there is “no particular shipment” that explains the rebound reported by international media in the supply to the Island.
The president said that asked Petróleos Mexicanos (PEMEX) for data to provide a “historical trend” of shipments and maintained that the current flow is part of contracts and humanitarian aid.

According to data from the monitoring firm Kpler cited by that medium, the Aztec country exported to the Island an average of 12,284 barrels of crude oil per day last year, equivalent to 44% of the Island’s total crude oil imports.
The same source indicates that Venezuela, historically the main supplier to Havana, came in second place with 9,528 barrels per day (34% of the total). Although this volume was similar to that of 2024, it was 63% below the level of 2023.
