The U.S. Treasury Department on Monday imposed sanctions on a network of Mexican companies and individuals accused of supplying precursor chemicals for fentanyl production to the notorious “Chapitos” wing of the Sinaloa cartel — a group led by the sons of jailed kingpin Joaquín “El Chapo” Guzmán.
In total, twelve Mexico-based businesses and eight individuals were blacklisted for allegedly using pharmaceutical, chemical, cleaning, laboratory, and real estate fronts to funnel key ingredients to cartel operations. Among those sanctioned is Sumilab, a company previously targeted by the Biden administration in 2023 but which, according to Treasury officials, evaded restrictions by restructuring under new front entities.
The sanctions freeze any assets held in the United States and prohibit American citizens or companies from conducting transactions with the named entities and individuals.
“These businesses were part of a sophisticated supply chain fueling the deadly fentanyl trade,” said Under Secretary for Terrorism and Financial Intelligence John K. Hurley. “President Trump has made it clear: stopping the flow of narcotics into the U.S. is a top national security priority.”
The action is part of a broader Trump administration strategy to designate powerful drug trafficking organizations — including factions of the Sinaloa cartel — as foreign terrorist organizations. The designation, typically reserved for politically motivated groups, is being applied to criminal enterprises that U.S. officials say are fueling the opioid crisis.
While groups like the Chapitos faction focus primarily on profit rather than ideology, Trump has insisted that their impact warrants harsher classification. “We are in an armed conflict with these cartels,” he said last week, referencing U.S. strikes on suspected drug vessels in the Caribbean — a move that has raised tensions across Latin America.
The sanctions reflect a continued escalation in Washington’s efforts to sever cartel financial networks, limit the flow of synthetic opioids, and pressure regional partners to cooperate more forcefully in combatting transnational organized crime.
