Federal authorities announced Wednesday the seizure of more than 600,000 gallons of biodiesel in 90 shipments bound for Cuba, valued at over $2.8 million, as part of ongoing enforcement of U.S. sanctions against the island's regime.

Homeland Security Investigations Miami and Houston offices, working with Customs and Border Protection and the Commerce Department's Bureau of Industry and Security, detained the fuel at Port Everglades in Florida and the Port of Houston in Texas. The shipments were headed to ENETEC S.A., a Havana-based, state-owned fuel company sanctioned by the Treasury Department earlier this year.

Seventy-one shipments totaling approximately 496,000 gallons were seized at Port Everglades, while 19 additional shipments containing about 119,000 gallons remain detained in Houston. The biodiesel was transported in ISO tanks and identified through intelligence and trade data analysis beginning in early September.

José R. Figueroa, special agent in charge of HSI Miami, described the operation as a deliberate attempt to undermine U.S. sanctions. "An effort of this magnitude to undermine U.S. sanctions does not occur by accident," he said during a news conference in Miami.

The action aligns with the Trump administration's policy of restricting fuel exports to Cuba's government while permitting limited shipments to the private sector. ENETEC S.A. was sanctioned in July under measures aimed at blocking financing for the Cuban regime and restricting its energy sector.

This seizure follows a Coast Guard interdiction last week of vessels attempting to smuggle fuel to Cuba, underscoring continued federal efforts to enforce export controls and deny resources to the sanctioned entity.
