US sanctions CJNG-linked fuel network as cartels expand beyond drug trafficking

The United States has sanctioned two Mexican nationals and nine companies accused of operating a cross-border fuel-smuggling network that generated tens of millions of dollars for the Cartel Jalisco Nueva Generación (CJNG).

The United States Department of the Treasury announced the measures on Tuesday, June 30, 2026, targeting Oscar Guillermo Juraidini Silva, J. Refugio Ruiz Villagomez and businesses operating across transportation, logistics, financial services and real estate. The department alleges that the network moved fuel from the United States into Mexico using false customs declarations, shell companies and intermediaries that helped avoid Mexican import taxes.

The sanctions freeze property belonging to the designated individuals and companies when it is located in the United States or controlled by United States persons. American businesses and financial institutions are generally prohibited from conducting transactions involving the sanctioned network unless the Office of Foreign Assets Control provides an exemption or licence.

The action highlights the growing importance of fuel theft and smuggling within Mexico’s organised-crime economy. United States authorities now regard stolen crude oil and illicit fuel trading as the largest non-drug revenue source for Mexican cartels and the second-largest cartel income stream after narcotics.

Who did the United States sanction over the alleged CJNG fuel-smuggling enterprise?

The United States Department of the Treasury designated Oscar Guillermo Juraidini Silva as a business facilitator accused of creating shell companies, falsifying customs documentation and importing fuel that was intentionally mislabelled to avoid Mexico’s Special Tax on Production and Services.

United States authorities described Oscar Guillermo Juraidini Silva as an accountant who managed financial operations benefiting the Cartel Jalisco Nueva Generación. The Treasury alleges that the activities generated tens of millions of dollars annually for the cartel-linked enterprise. These remain United States government allegations rather than findings reached after a criminal trial.

Seven businesses owned or controlled by Oscar Guillermo Juraidini Silva were also sanctioned. The Mexican entities are Centro Cambiario La Peseta, OJ Living Trust, RK Real King, Soma Transporte y Servicios, Ogui Fletes and OF Transportes. The United Kingdom-based company Cucumber Sweet Waves was also designated.

J. Refugio Ruiz Villagomez and two logistics businesses, Jomadi Logistics & Cargo and Ahavat Logistics Solution, were sanctioned separately. The Treasury alleges that J. Refugio Ruiz Villagomez knowingly moved fuel from the United States into Mexico without the required permits and paid fees to criminal organisations controlling border entry points.

The designated individuals and most companies could not immediately be reached for comment. Several businesses that received questions from Reuters did not respond, and the news agency was unable to identify public contact information for other sanctioned entities.

How does fuel move from United States suppliers into cartel-controlled Mexican markets?

The alleged scheme begins with Mexico’s continuing demand for imported petrol, diesel, naphtha and other refined products. Mexico produces substantial quantities of crude oil, but its ageing refinery system has often been unable to supply enough finished fuel for domestic consumption, creating a large and commercially legitimate import market.

Cartel-linked brokers can exploit that market by purchasing fuel from United States distributors through Mexican trading companies. The fuel may then pass through networks of transporters, intermediaries and shell companies before crossing the border by tanker truck, railcar or maritime vessel.

The central fraud involves customs classification. Diesel, petrol or naphtha can be described in documents as lubricants, waste oil or another product that receives different tax treatment. Mexico’s Special Tax on Production and Services places a substantial levy on imported motor fuel, making misclassification highly profitable.

The illicit fuel can subsequently be delivered to storage yards and sold through cartel-affiliated petrol stations, independent roadside outlets or distributors willing to purchase fuel below normal wholesale prices. False invoices and trading companies can make the product appear legitimate as it enters the Mexican retail system.

The United States Department of the Treasury alleges that some United States distributors knowingly participate, while others may be exploited by intermediaries. Established relationships with refineries and wholesalers can allow smaller trading businesses to purchase large quantities of fuel before diverting the product through less transparent counterparties.

Why is Mexico’s fuel-import tax central to the profitability of huachicol fiscal?

The cross-border tax-evasion model is commonly described in Mexico as huachicol fiscal. Traditional huachicol involves stealing fuel from pipelines, refineries or tanker trucks, while huachicol fiscal relies on importing refined products under false descriptions to avoid tax.

The savings can represent a substantial portion of a shipment’s value. A Reuters investigation found that approximately 120,000 barrels of diesel transported to Mexico aboard the tanker Torm Agnes were declared as lubricants, potentially avoiding around $7 million in Mexican duties.

Trade-document manipulation can be difficult to detect when the exporter and importer use matching product codes. Customs agencies cannot physically inspect every shipment, meaning coordinated false declarations on both sides of the border may appear consistent within automated systems.

The process becomes more sophisticated when legitimate companies, licensed distributors and established logistics providers appear at different stages of the transaction. A shipment may originate from a recognised refinery and travel aboard a conventional tanker before being delivered to an importer with little public presence or no appropriate fuel-import permit.

The Mexican government loses revenue that would otherwise support public spending, while cartel-linked sellers gain a pricing advantage over businesses paying the required tax. Legitimate petrol stations and distributors may consequently face competition from fuel sold at prices that cannot be matched through lawful imports.

How large has fuel smuggling become within Mexico’s organised-crime economy?

The United States Department of the Treasury estimates that fuel and oil crime has developed into the most significant non-drug revenue source for Mexican cartels. Public reporting cited by the department suggests that between one-quarter and one-third of fuel sold in Mexico may be illicit, although the precise national share is difficult to verify.

The illicit market includes several connected activities. Criminal groups steal refined products from Petróleos Mexicanos pipelines, remove crude oil from Mexican infrastructure, smuggle Mexican crude into the United States and move untaxed refined fuel in the opposite direction.

Cartels may bribe employees, threaten transport workers, drill illegal pipeline taps, hijack tanker trucks or gain influence inside ports and customs operations. Maritime smuggling demonstrates how the business has expanded beyond the small-scale roadside fuel theft historically associated with huachicol.

The United States Department of the Treasury said fuel-related activity has enabled the Cartel Jalisco Nueva Generación to finance narcotics trafficking, corruption and violence against Mexican authorities. The proceeds can also be laundered through real estate, luxury vehicles, jewellery, travel and investment assets.

The scale changes the policy response required from both countries. Fuel crime can no longer be treated only as theft from Petróleos Mexicanos or a Mexican tax-enforcement problem. It now involves international trade, banking, United States suppliers, shipping companies, ports and corporate due diligence.

What do suspicious bank transactions reveal about cartel-linked energy trading?

The Financial Crimes Enforcement Network issued additional guidance alongside the sanctions to help banks identify warning signs connected to cross-border fuel smuggling.

After an earlier alert on crude-oil smuggling, financial institutions filed more than 160 Suspicious Activity Reports describing over $7 billion in potentially suspicious activity during a 12-month period. Many reports involved transactions between the United States and Mexico and frequently referenced the Cartel Jalisco Nueva Generación.

Texas and Florida were among the United States locations most frequently appearing in the reports. In Texas, many subjects were located near the Mexican border in places including Brownsville, Mission, Eagle Pass and McAllen, with connections to transportation, oil and natural gas businesses.

Warning signs can include international transfers between companies with little obvious commercial presence, fuel payments made through unrelated shell businesses, inconsistent product descriptions and customers lacking normal energy-sector licences.

Digital-asset payments can also be used alongside conventional bank transfers. Cartel-linked brokers may route payments through pass-through accounts before funds reach a United States fuel distributor, making the economic purpose harder to identify.

The guidance increases pressure on banks, commodity traders and logistics companies to understand their counterparties. A commercially plausible invoice is no longer sufficient when the customer has no verifiable address, lacks import permits or repeatedly uses product classifications inconsistent with the cargo being shipped.

Why are American companies and international fuel traders exposed to greater legal risk?

The sanctions prohibit United States persons from dealing with the newly designated individuals and entities. Companies that continue processing transactions can face civil or criminal penalties, while foreign financial institutions may also face consequences for knowingly facilitating significant transactions involving persons sanctioned under counterterrorism authorities.

The Cartel Jalisco Nueva Generación was designated as a United States foreign terrorist organisation and specially designated global terrorist in February 2025. That classification increases the legal risk for businesses suspected of providing material support, financing, transportation or commercial services to cartel-linked entities.

Fuel companies may argue that they sold products to apparently ordinary wholesalers and had no knowledge of a cartel connection. Authorities will examine whether the company conducted reasonable due diligence, verified permits and investigated unusual payment patterns or inconsistencies in shipping documentation.

The United States investigation into Houston-based petroleum trader Ikon Midstream shows how quickly commercial relationships can attract regulatory scrutiny. Homeland Security Investigations executed a search warrant at the company’s Houston office in April 2026 as part of an investigation into suspected criminal activity.

Ikon Midstream has denied knowingly supporting the Cartel Jalisco Nueva Generación and has said that inaccuracies in its export filings were clerical mistakes. The company has not been charged in connection with the June 30 sanctions, and the businesses targeted by the latest Treasury action are separate from Ikon Midstream.

The broader lesson for the fuel industry is that counterparties must be examined beyond sanctions databases. Companies may need to verify physical addresses, import permissions, ownership, trade history and whether the customer has the operational capacity expected of a genuine wholesale fuel buyer.

How are the United States and Mexico coordinating against cartel fuel networks?

The June 30 action was coordinated with Mexico’s Financial Intelligence Unit and a South Texas Homeland Security Task Force investigation involving several United States agencies.

Participating authorities included the Drug Enforcement Administration, Homeland Security Investigations, the Federal Bureau of Investigation, Internal Revenue Service Criminal Investigation, United States Customs and Border Protection and the Bureau of Industry and Security.

Mexico has separately expanded investigations into suspected fuel smuggling at the ports of Guaymas, Tampico and Ensenada. Internal inquiries have examined possible misconduct involving port personnel, customs authorities and the Mexican Navy.

Mexican authorities previously arrested customs and naval officials accused of participating in an alleged criminal structure linked to illicit fuel imports. Those arrests underline the importance of official corruption to an operation requiring large cargoes to move through regulated ports and customs facilities.

Cooperation remains politically sensitive because Mexico is protective of its sovereignty and resists suggestions that United States agencies should conduct unilateral operations inside the country. Washington, meanwhile, views cartel revenue as directly connected to fentanyl trafficking and violence affecting United States citizens.

Financial sanctions offer a tool that can be applied without deploying forces or requesting extradition immediately. They isolate named businesses from the dollar system, alert banks and increase the cost of conducting international transactions.

Sanctions alone will not eliminate the trade. Networks can create replacement companies, recruit new intermediaries or alter routes. Lasting disruption will require criminal prosecutions, permit enforcement, customs reform and stronger inspection of both land and maritime shipments.

Could the fuel crackdown disrupt legitimate energy trade between Mexico and the United States?

Mexico remains a major purchaser of refined fuel from the United States, and most cross-border energy trade is lawful. Authorities must therefore distinguish suspicious networks from legitimate importers without delaying normal shipments or creating shortages.

Overly broad restrictions could raise compliance costs for distributors and transporters. Banks may become reluctant to process transactions involving smaller Mexican fuel buyers, particularly when ownership records or licensing systems are difficult to verify.

More intensive inspections at ports and border crossings could also slow cargo movement. However, continued criminal infiltration presents its own supply risk because cartel-controlled distribution undermines tax revenue, legitimate retailers and public confidence in the fuel market.

Improved traceability offers a possible middle path. Mexico has promoted systems intended to follow imported fuel from its point of origin through customs, transport, storage and retail sale. Effective implementation would make it harder for untaxed fuel to be mixed with legitimate supplies.

The June 30 sanctions signal that energy-security policy and organised-crime enforcement are becoming increasingly connected. The central challenge is to protect a valuable regional trade relationship while closing the tax and documentation gaps that turned fuel into one of Mexico’s most lucrative illicit commodities.

What are the key takeaways from the United States sanctions on the CJNG fuel network?

• The United States Department of the Treasury sanctioned two Mexican nationals and nine entities on June 30, 2026, over allegations that they facilitated fuel smuggling and tax evasion benefiting the Cartel Jalisco Nueva Generación.
• Oscar Guillermo Juraidini Silva was accused of creating shell companies, falsifying customs documentation and importing deliberately mislabelled fuel, while seven businesses under his ownership or control were also added to sanctions lists.
• J. Refugio Ruiz Villagomez, Jomadi Logistics & Cargo and Ahavat Logistics Solution were designated over alleged involvement in moving United States fuel into Mexico without the necessary permits and supporting cartel-linked operations.
• The alleged huachicol fiscal model involves falsely declaring petrol, diesel or naphtha as lubricants or other lower-tax products before selling the fuel through cartel-linked petrol stations and unregulated roadside outlets.
• United States authorities consider fuel and oil crime the largest non-drug source of cartel revenue, while public estimates suggest that a substantial portion of fuel sold in Mexico may come from illicit sources.
• Financial institutions submitted more than 160 Suspicious Activity Reports describing over $7 billion in potentially suspicious transactions after earlier United States guidance on cross-border cartel-linked oil and fuel activity.
• The sanctions freeze United States-linked assets and generally prohibit American transactions with the designated parties, while foreign financial institutions can also face exposure for knowingly facilitating significant business with sanctioned entities.
• The crackdown will require continued cooperation between United States and Mexican customs, financial-intelligence, law-enforcement and port authorities because sanctioned businesses can be replaced unless the underlying trade and corruption networks are dismantled.
