Overview

• OFAC designated a network centered on Culiacán-based lab supplier Sumilab and affiliates linked to the Favela López family for providing precursors and equipment to the Sinaloa Cartel’s Los Chapitos faction.
• The measures block all property in the United States or held by U.S. persons and prohibit U.S. transactions with the listed parties, with the 50 percent ownership rule extending restrictions to controlled entities.
• Treasury says Sumilab stayed active after 2023 sanctions by using front companies and corporate changes, prompting a broader action that names additional firms including Agrolaren, Viand, Favelab, Qui Lab, and Storelab.
• Individuals designated include Jorge Luis, Francisco, and Víctor Andrés Favela López, as well as broker Martha Emilia Conde Uraga, who Treasury alleges used fraudulent invoicing to supply chemicals from sites in Culiacán.
• Officials describe the move as coordinated with Mexican authorities and part of a wider strategy that leverages the Sinaloa Cartel’s Foreign Terrorist Organization designation.
