Sanctions: Cuba
Key Facts
—Who. US Homeland Security Investigations (HSI), Customs and Border Protection (CBP) and the Commerce Department’s Bureau of Industry and Security (BIS), acting against fuel bound for ENETEC S.A., a Havana fuel wholesaler under US sanctions.
—What. 90 biodiesel shipments worth over US$2.8 million were seized or detained, about 615,000 gallons in total, as announced on Wednesday 7 October 2026.
—Where. 71 shipments (about 496,000 gallons) at Port Everglades, Florida, and 19 shipments (about 119,000 gallons) at the Port of Houston, Texas.
—US link. The cargo was set to leave from US ports, so the case is about US exporters. Agents cite suspected breaches of export law and the International Emergency Economic Powers Act (IEEPA).
—Status. The investigation is ongoing. The agencies have named no exporter and announced no charges.
—Prediction markets. Polymarket prices a US military action against Cuba by 31 December at 12.5% (about US$7.6 million traded). Prices are bets, not polls, read on 7 October 2026 at 7:50 p.m. ET.
—As of. 7 October 2026, 23:50 GMT.
US federal agents stopped 90 shipments of biodiesel worth more than US$2.8 million that were bound for ENETEC S.A., a Cuban fuel wholesaler under US sanctions. The announcement on Wednesday 7 October 2026 shows Washington enforcing its Cuba sanctions at American ports, not only on the sanctions list.
The cargo was headed out of two US ports, so the case turns on American exporters rather than on Cuba alone. That makes it a story about US trade compliance as much as about Havana.
What We Know
HSI Miami announced the seizures together with HSI Houston, CBP and BIS, according to a news release from US Immigration and Customs Enforcement (ICE), the agency that HSI belongs to. CBP identified the shipments in early September 2026 through intelligence and trade-data analysis.
Of the 90 shipments, 71 (about 496,000 gallons) were seized at Port Everglades in Florida, and 19 (about 119,000 gallons) are being detained at the Port of Houston in Texas. Together that is about 615,000 gallons, which some Miami-based outlets round to 620,000.
ICE says investigators developed information that the Cuban government used ENETEC S.A. to receive fuel exported illegally from the United States, and that the cargo was headed there. The seizures rest on suspected violations of federal export law, the Export Administration Regulations and IEEPA, the law behind most US sanctions.
“This seizure underscores HSI Miami’s commitment to stopping fuel and other goods from the United States from being illegally exported to Cuba through sanctioned entities or deceptive commercial networks,” said Jose R. Figueroa, the HSI Miami special agent in charge. WSVN, a Miami broadcaster, reports that Figueroa also said the actions are not meant to interfere with legitimate humanitarian assistance for Cuban families.
Who Is ENETEC S.A.?
The US Treasury’s Office of Foreign Assets Control (OFAC) added ENETEC S.A. to its sanctions list on 13 July 2026 under Executive Order 14404. OFAC’s entry describes it as a wholesaler of solid, liquid and gaseous fuels, based in Havana and established on 9 December 2019.
The State Department designated the company the same day for operating in the energy sector of the Cuban economy. Under sanctions, its assets under US jurisdiction are blocked, and US persons generally cannot deal with it without an OFAC licence.
In June, the State Department had already sanctioned Cuba’s state oil and gas company, Unión Cuba-Petróleo (Cupet). The seized cargo shows that the pressure now reaches fuel before it leaves US ports.
How Big Is the Seizure?
At 42 US gallons to the barrel, 615,000 gallons is about 14,600 barrels. The US Energy Information Administration (EIA) reported that the United States exported a record 3.22 million barrels of petroleum products to Cuba in July 2026, so the seized cargo equals roughly 0.5% of that single month.
That comparison is only a check on scale, because the seized fuel is biodiesel and the EIA series counts petroleum products. We covered the record July exports of US fuel to Cuba when the EIA data came out on 30 September.

Reported values differ slightly by outlet. ICE puts the 90 shipments at over US$2.8 million, while some Miami outlets say almost US$3 million.
What Is Not Known
ICE’s release does not name the exporters, and the agencies have not said whether anyone will be charged. HSI Miami, HSI Houston, CBP and BIS continue to investigate.
It is also unclear what happens to the cargo, including the 19 shipments still detained in Houston. The agencies have not said whether the fuel will be forfeited, returned or sold.
What Prediction Markets Say
Polymarket, an online prediction market, prices a US military action against Cuba by 31 December 2026 at 12.5%, with about US$7.6 million traded. Prices are bets, not polls, and they were read on 7 October 2026 at 7:50 p.m. ET.
The same platform prices a US-Cuba economic deal by 31 December at 12.0% (about US$442,000 traded) and Miguel Díaz-Canel out as president by that date at 13.0% (about US$375,000 traded). None of these markets is tied to the seizure itself.
Why we show this: prediction markets turn real-money bets into a live probability that moves within minutes of the news, which is why investors, campaigns and newsrooms in the United States now follow them closely. We show them next to polls and official results, never instead of them.
What It Means for US Readers and Investors
For US exporters, freight forwarders and port operators, the case shows that cargo bound for a sanctioned Cuban consignee can be stopped at Florida and Texas ports. The agencies cite export law and IEEPA, which can carry civil and criminal penalties.
The State Department has announced new Cuba sanctions in every month from June to September, and our earlier reporting on the sanctions push shows how the list has grown. Further rounds, and any charges against the exporters in this case, are the next signals to watch.
