Background on Key Figures and Organizations

The US Department of the Treasury imposed sanctions on Monday against eight individuals and twelve companies based in Mexico for their alleged involvement in the trafficking of fentanyl through a faction of the Sinaloa Cartel known as “Los Chapitos.”

Who are the Key Players?

  • Joaquín ‘El Chapo’ Guzmán: A notorious Mexican drug lord, whose sons are central to the “Los Chapitos” faction.
  • Archivaldo Iván Guzmán and Jesús Alfredo Guzmán: Sons of Joaquín ‘El Chapo’ Guzmán, leading the “Los Chapitos” faction and controlling vast Mexican territories under the Sinaloa Cartel.
  • Favela López Family: A prominent Mexican family with business interests in various sectors, including pharmaceuticals and agriculture. The family is linked to the fentanyl trafficking operation through their companies.

Which Companies are Affected?

  • Sumilab: A company previously sanctioned and now targeted again, controlled by the Favela López family.
  • Agrolaren, Distribuidora de Productos y Servicios Viand, Favelab, Favela Pro, Qui Lab, and Storelab: Companies linked to the Favela López family and sanctioned due to their ties to the fentanyl trafficking operation.
  • Macerlab: A company sanctioned due to its connection with César Elías López Araujo, who is related to Víctor Andrés Favela López and involved in the family business.

Additional Sanctioned Individuals and Companies

  • Martha Emilia Conde Uraga: Linked to the Sinaloa Cartel and four sanctioned companies.
  • Comercial Viosma del Noroeste, Prolimph Quimicos en General, Proveedora de Servicios de Salud Mental del Pacífico, and Roco del Pacifico Inmobiliaria: Companies sanctioned alongside Martha Emilia Conde Uraga.

Rationale Behind the Sanctions

John K. Hurley, the Acting Assistant Secretary for Terrorism and Financial Intelligence at the US Department of the Treasury, stated that these sanctions target a network responsible for illicitly supplying chemical precursors used in fentanyl production to the Sinaloa Cartel’s “Los Chapitos” faction. The cartel is designated as a terrorist organization by the United States.

Hurley emphasized that over 500,000 Americans have died from fentanyl overdoses, highlighting the urgency of curbing the flow of these dangerous drugs. Under Secretary Scott Bessent’s leadership, the Treasury aims to dismantle the complex financial networks supporting these terrorist organizations.

Impact on Key Individuals and Companies

The sanctions imposed on the Favela López family members, including Víctor Andrés Favela López, Francisco Favela López, Jorge Luis Favela López, María Gabriela Favela López, Jairo Verdugo Araujo, and Gilberto Gallardo García, restrict their access to the US financial system. This limits their ability to conduct transactions and freeze any assets under US jurisdiction.

Similarly, the sanctions against companies like Sumilab, Agrolaren, Distribuidora de Productos y Servicios Viand, Favelab, Favela Pro, Qui Lab, Storelab, Macerlab, Comercial Viosma del Noroeste, Prolimph Quimicos en General, Proveedora de Servicios de Salud Mental del Pacífico, and Roco del Pacifico Inmobiliaria prevent them from engaging in transactions with US entities.
