This Wednesday in Miami, U.S. federal authorities reported the interception of 90 shipments of biodiesel destined for Cuba, valued at nearly $3 million. The investigation into those responsible for this operation is still active, with no formal charges filed or identities disclosed.
As detailed in a CBS News report, the combined effort was conducted by Homeland Security Investigations (HSI), U.S. Customs and Border Protection (CBP), and the Department of Commerce's Bureau of Industry and Security.
The intended recipient of these shipments was ENETEC S.A., a state-owned Cuban fuel wholesaler based in Havana. This company, along with COREYDAN S.A., was sanctioned by the Office of Foreign Assets Control (OFAC) in July 2026 for its involvement in Cuba's energy sector.
In total, the agencies seized over 620,000 gallons of biodiesel: 71 storage tanks containing approximately 500,000 gallons at Port Everglades, Florida, and 19 additional shipments with around 120,000 gallons at the Port of Houston, Texas.
Agencies Uncover Fuel Smuggling Operation
In early September, after reviewing trade and intelligence data, CBP discovered that fuel exported from the U.S. was reaching a sanctioned entity, allegedly violating the International Emergency Economic Powers Act and Export Administration Regulations.
The agencies have yet to reveal the masterminds behind this scheme. At the announcement, authorities did not disclose the identities of the involved exporters nor confirm any criminal charges, leaving the investigation ongoing.
Jose Figueroa, the special agent in charge of HSI Miami, vowed to "continue identifying, disrupting, and investigating efforts to evade U.S. sanctions, safeguard export controls' integrity, and prevent the Cuban government from accessing resources obtained illegally."
Impact on Cuba's Energy Crisis
This land-based interception follows earlier maritime operations by the U.S. Coast Guard: on September 5, they boarded the cargo ship M/V Grace in the Caribbean between Cuba and Mexico, and in late June, they intercepted the Jaira Provider near Mayagüez, Puerto Rico, carrying over 200,000 gallons of diesel.
The Cuban regime, through Deputy Foreign Minister Carlos Fernández de Cossío, condemned Washington's actions as illegal and immoral, stating: "It is illegal, immoral, and criminal to subject an entire nation to economic suffocation as collective punishment for political purposes."
Cuba's energy crisis exacerbates the impact of these measures. The island produces about 40,000 barrels daily but requires between 90,000 and 110,000, relying on imports for roughly 60% of its demand.
In 2026, at least eight total collapses of the national electrical system have been recorded, with blackouts lasting up to 20 to 24 hours daily. These outages have disrupted water pumping for around 3.5 million people in Havana and caused interruptions in hospitals, transportation, and food storage.
The situation worsened following the suspension of Venezuelan oil shipments since November 2025 and the significant reduction in Mexican supplies, leaving Cuba without its main external crude sources.
Future Legal Ramifications
The ongoing investigation will determine whether the exporters who sent biodiesel to ENETEC were aware of the existing sanctions or were misled about the final destination of the cargo—an important distinction that could influence the severity of any charges eventually filed.
Key Questions Surrounding U.S. Fuel Seizure
What agencies were involved in the biodiesel interception operation?
The operation was a joint effort by Homeland Security Investigations (HSI), U.S. Customs and Border Protection (CBP), and the Department of Commerce's Bureau of Industry and Security.
What is the role of ENETEC S.A. in this operation?
ENETEC S.A. is the state-owned Cuban fuel wholesaler that was the intended recipient of the biodiesel shipments. It was sanctioned by the OFAC for operating in Cuba's energy sector.
How has Cuba's energy crisis been affected by these actions?
The interception of the shipments exacerbates Cuba's energy crisis, as the island heavily depends on fuel imports to meet its energy demands. This has led to frequent blackouts and disruptions in essential services.
