What is ENETEC, the company of the Cuban regime that received the fuel intercepted by the U.S.?

Until a few months ago, ENETEC S.A. was a virtually unknown state-owned company in Cuba outside the island's commercial circuits. 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 addressed to this company.

The operation, , brought attention to a company engaged in the import, export, and wholesale trade of fuels and lubricants that took on a much more prominent role in 2026.

ENETEC was established on December 9, 2019. The Office of Foreign Assets Control of the Department of the Treasury (OFAC) identifies it with the Cuban entity code 60631 and classifies it within the wholesale trade of solid, liquid, and gaseous fuels.

Its public address simply appears as Havana, and the available information about its internal structure is scarce.

The company's rise became more evident this year. Through Resolution 20/2026, signed on February 19, the Ministry of Foreign Trade and Foreign Investment included ENETEC as the 53rd authorized entity to conduct foreign trade operations with non-state management forms, including small and medium-sized enterprises, 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 the measure due to the company's activities in the Cuban energy sector. Following its designation, its assets and interests subject to U.S. jurisdiction were blocked, and U.S. persons are generally prohibited from engaging in transactions with it without authorization from the OFAC.

The company reemerged on the authorities' radar in September, when the Miami-Dade tax collector revoked the local business license of Lux Sky Cargo Inc. effective immediately, after receiving information from federal agencies indicating that the company was conducting business with ENETEC.

The most significant episode occurred this Wednesday.

National Security Investigators (HSI), Customs and Border Protection (CBP), and the Bureau of Industry and Security (BIS) reported that they had intercepted 71 tanks containing 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, the authorities intercepted more than 620,000 gallons of biodiesel, valued at around 2.8 million dollars, which was intended for ENETEC.

The agencies did not publicly identify the involved exporters nor announce any criminal charges. The investigation is related to possible violations of the International Emergency Economic Powers Act (IEEPA) and U.S. export control regulations.

The increasing attention on ENETEC comes amid Cuba's severe energy crisis, marked by fuel shortages and prolonged blackouts, while Havana relies on imports to meet a substantial portion of its needs.

When announcing the new round of sanctions against Cuban entities on July 13, the State Department recalled a statement made two days prior by Marco Rubio, in which the Secretary of State asserted that the United States would continue to use "all the tools" at its disposal to confront the threats it attributes to the Cuban regime and promote economic and political reforms on the island.
