Where is Matanzas in Cuba?: Matanzas province lies on Cuba's northern coast approximately 100 kilometres east of Havana. Its main city and Matanzas Bay industrial port make it a key industrial and agricultural hub and Cuba's primary oil import terminal.
Why is the Sovcomflot tanker Universal going to Matanzas?: Matanzas Bay is Cuba's primary oil-import terminal. The Universal (expected around 29 April 2026) will offload Russian crude there under OFAC GL 134B cover; the cargo then travels to the Camilo Cienfuegos refinery in Cienfuegos province for processing.Source: OFAC / Cuba Dispatch

Background

Matanzas province lies on Cuba's northern coast approximately 100 kilometres east of Havana. With a population of approximately one million, it is Cuba's third most populous province and an industrial and agricultural hub. The province hosts Varadero, Cuba's largest international resort zone, the Matanzas Bay industrial port — the primary Cuban oil-import terminal — and the former Supertanker Base, a major fuel storage facility badly damaged in a September 2022 explosion and fire that destroyed more than a million barrels of oil and killed at least 16 firefighters.

Matanzas Bay remains the intended unloading port for the Sovcomflot Universal, a 50,923 DWT tanker carrying 270,000 barrels of diesel from Russia. As of 18 May 2026 the vessel remains offshore: last AIS broadcast on 29 April at 2.2 knots west-south-west, roughly 1,000 to 1,600 kilometres from Cuba with no declared destination. OFAC's General Licence 134B expired on 16 May with no Cuba-specific successor licence under EO 14404, and the GL 134B operative text explicitly excluded transactions involving persons in or organised under the laws of Cuba. Matanzas's terminal therefore has no legal cargo to receive while the vessel sits in an authorisation envelope that never included Cuba. The Camilo Cienfuegos refinery in Cienfuegos province, the downstream waypoint that restarted on 17 April 2026 using Anatoly Kolodkin crude, is the operational backstop for any cargo that does land at Matanzas, though it has run on dwindling stock since the previous Sovcomflot delivery.

The province sits west of the 14 May SEN fragmentation point that cut off Granma, Santiago de Cuba and Guantánamo from central dispatch. Bloomberg satellite analysis of Cuban nighttime light identified Holguín and Santiago de Cuba as the worst-affected provinces; Matanzas was not named individually but the broader east-west spatial bias of the outage pattern suggests the western provinces retained partial priority. Matanzas was among the 8 provinces identified by the UN Resident Coordinator in April 2026 as having acute humanitarian needs.
