The U.S. Department of the Treasury on Oct. 6 sanctioned Mexican companies and individuals accused of supplying precursor chemicals for fentanyl production to a Sinaloa Cartel faction.
The ingredients for fentanyl are produced in China and exported to Mexico, where syndicates such as the Sinaloa Cartel and the Jalisco New Generation Cartel (CJNG) manufacture the deadly product, which is shipped across the border for a customer base of U.S. addicts.
