Until recently, ENETEC S.A. was a virtually unknown Cuban state enterprise outside the island's commercial circles. This Wednesday, it became the focus of a federal investigation in the United States: 90 shipments of biodiesel intercepted in Florida and Texas, valued at nearly three million dollars, were intended for this company.
The operation, unveiled by U.S. authorities, has spotlighted a business engaged in the import, export, and wholesale trading of fuels and lubricants, which took on a more prominent role in 2026.
ENETEC's Genesis and Expansion
ENETEC was established on December 9, 2019. The Office of Foreign Assets Control (OFAC) of the Department of the Treasury identifies it with the Cuban entity code 60631, classifying it within the wholesale trade of solid, liquid, and gaseous fuels.
The company's public address is simply listed as Havana, with scant information available on its internal structure.
U.S. Sanctions and Regulatory Actions
The rise of the company became more apparent this year. On February 19, through Resolution 20/2026, the Ministry of Foreign Trade and Foreign Investment incorporated ENETEC as the 53rd entity authorized to engage in foreign trade operations with non-state management forms, including micro, small, and medium enterprises (MSMEs), cooperatives, and self-employed workers.
Months later, on July 13, the United States added ENETEC to the list of Specially Designated Nationals and Blocked Persons (SDN) under Executive Order 14404. Washington justified this measure due to the company's activities in Cuba's energy sector. Following this designation, its assets and interests under U.S. jurisdiction were blocked, and U.S. persons were generally prohibited from conducting transactions with it without OFAC authorization.
Intercepted Fuel Shipments
The company once again caught the attention of authorities in September when the Miami-Dade tax collector immediately revoked the local business permit of Lux Sky Cargo Inc., after receiving information from federal agencies indicating the company conducted business with ENETEC.
The most significant episode occurred this Wednesday. Homeland Security Investigations (HSI), Customs and Border Protection (CBP), and the Bureau of Industry and Security (BIS) announced they had intercepted 71 tanks with approximately 500,000 gallons of biodiesel at Port Everglades, Florida, and another 19 shipments with about 120,000 gallons at the Port of Houston, Texas.
In total, authorities blocked over 620,000 gallons of biodiesel, valued at around 2.8 million dollars, intended for ENETEC. The agencies did not publicly identify the exporters involved nor announce any criminal charges. The investigation is related to potential violations of the International Emergency Economic Powers Act (IEEPA) and U.S. export control regulations.
Implications Amid Cuba's Energy Crisis
The growing scrutiny of ENETEC arises amid Cuba's severe energy crisis, characterized by fuel deficits and prolonged blackouts, while Havana relies heavily on imports to meet a substantial portion of its energy needs.
When announcing the new round of sanctions against Cuban entities on July 13, the State Department recalled a statement made two days earlier by Marco Rubio, in which the Secretary of State assured that the United States would continue using "all tools" at its disposal to counter threats attributed to the Cuban regime and promote economic and political reforms on the island.
