British Company Hits OFAC List in CJNG Fuel-Smuggling Designations

A UK-registered company now sits on the US sanctions list. Cucumber Sweet Waves Ltd is among nine entities blocked by the Office of Foreign Assets Control (OFAC) in a coordinated action against the fuel-smuggling network of Cartel de Jalisco Nueva Generacion (CJNG), issued alongside a supplemental Financial Crimes Enforcement Network (FinCEN) Alert on the laundering typologies that sustain it. For UK institutions, the British nexus is the immediate point of exposure: any counterparty relationship, beneficial-ownership link or dollar-clearing flow touching that entity warrants screening now, and the counterterrorism basis of the designation raises the stakes considerably.

The entity is one of six companies tied to Oscar Guillermo Juraidini Silva, described as the accountant who builds and runs shell companies for the cartel and falsifies customs documentation to move refined fuel from the United States into Mexico while evading the Impuesto Especial sobre Producción y Servicios (IEPS). His network spans transportation, financial services and real estate. A second individual, J Refugio Ruiz Villagomez, was designated with logistics firms Jomadi Logistics & Cargo and Ahavat Logistics Solution, which allegedly moved tens of millions of dollars through the US financial system in support of the cartel.

The reason this merits a compliance officer's attention is the shape of the scheme rather than the designations themselves. This is trade-based money laundering operating entirely within the appearance of legitimate commercial trade — and that is precisely what makes it hard to catch. Complicit US distributors divert genuine product to interconnected front and shell companies across freight and logistics; Mexican trading firms issue false invoices to legitimise the fuel domestically; and settlement flows back through international wires, digital-asset transfers and structured cash deposits, frequently commingled with narcotics proceeds. No single transaction looks anomalous in isolation. The risk surfaces only when invoice values are tested against physical fuel volumes, when logistics counterparties show revenue inconsistent with observable commercial activity, and when payment routing fails to match the ostensible trade.

The practical consequence is that this typology reframes customer segments a UK institution would ordinarily treat as unremarkable: fuel and hydrocarbon wholesalers, freight and logistics operators, commodity trading intermediaries, and any client whose documentary trade finance can be tested against real-world movement of goods. The maritime dimension sharpens this further. FinCEN identifies shadow fleets of vessels moving the product — the same opaque-ownership, AIS-manipulation and flag-hopping patterns compliance teams are already screening in Russia-related evasion work. Hydrocarbon logistics, obscure trading intermediaries and shell-company layering should be treated as a single connected typology, not as discrete risks sitting in separate parts of the framework.

The scale explains the regulatory focus. In the twelve months after FinCEN's May 2025 crude-oil Alert, institutions filed over 160 Suspicious Activity Reports capturing more than $7 billion in suspicious activity, with public estimates suggesting a quarter to a third of all fuel sold in Mexico may be illicit. This is not a marginal typology confined to counterparties with visible cartel links; it is embedded in ordinary energy and logistics commerce, which is exactly why the detection burden falls on transaction-level scrutiny rather than name screening alone.
