Overview

• OFAC named Sumilab of Culiacán and a web of related companies that allegedly move chemical precursors and laboratory gear for the Sinaloa cartel’s Los Chapitos faction.
• Designations include members of the Favela López family — Víctor Andrés, Francisco, Jorge Luis and María Gabriela — along with Jairo Verdugo Araujo, Gilberto Gallardo García, Martha Emilia Conde Uraga and other operators.
• Targeted firms span chemicals, lab equipment, agriculture, cleaning, health and real estate, including Agrolaren, Viand, Favelab, Fagalab, Qui Lab, Storelab, Macerlab, Viosma, Prolimph, Salud and Roco.
• Treasury said Sumilab was first sanctioned in 2023 and that family members later pulled names from corporate records and used frontmen while remaining active in precursor supply.
• All U.S.-linked assets of the designated parties are blocked under OFAC rules, U.S. persons are barred from most dealings under the 50 percent rule, and violations can trigger civil or criminal penalties.
