Infographics | Arms Trafficking Across the US-Mexico Border

The United States and Mexico have grappled with increasing arms and drug trafficking for several years. In response to recent surges in violence, the Mexican Attorney General of the Republic (FGR) and the United States Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) undertook a joint effort to trace the origin and number of firearms in Mexico coming from or through the United States. Mexico’s Secretariat of Foreign Relations found that 70-90% of traced firearms originated from and passed through the US. ATF and the US Government Accountability Office (GAO) estimated a lower rate of 68%, comprising 50% domestically produced and 18% imported into the US, and ultimately found in Mexico.

ATF's data unveils compelling insights. Although pistols consistently topped the list of firearms found by the ATF, there was a 105% increase in rifles found in Mexico and reported from 2016 to 2022, meaning that cartels may be favoring this type of firearm. 

Specific US counties have been linked to weapons found across Mexican municipalities, spanning from the Pacific to the Atlantic Coasts, as highlighted by former Mexican Secretary of Foreign Affairs Marcelo Ebrard and the Office of the Attorney General of Mexico. Concurrently, the United Nations Office on Drugs and Crime (UNODC) has identified the presence of 'ant-trafficking,' the intentional diversion of firearms from legal channels, and straw purchases, where individuals buy guns on behalf of others, along these routes. These actions intensify the illegal transportation of firearms. The presence of guns in Mexico, as well as these two phenomena, demonstrate the connection of these trafficking routes, amplifying illegal firearm transportation. The increase in these practices necesitates enhanced collaborative efforts between the United States and Mexico to curb the unlawful flow of firearms.

"Ant-trafficking" is identified by UNODC as a cross-border firearm trafficking phenomenon that involves discreet movement of small quantities, often targeting localized demands. It is characterized by smaller batches and single straw purchases — a method where the intended buyer, either incapable of passing the mandatory federal background check or seeking to distance themselves from the transaction, employs another person who can successfully navigate the background check to acquire the firearm on their behalf— of larger quantities, suggesting an organized trade. Law enforcement data indicates that the majority of cross-border seizures involve fewer than five firearms, supporting the "ant trafficking" pattern (UNODC, 2020; ATF, 2021).

Moreover, the United States grapples with the persistent issue of firearms trafficking across both its northern and southern borders. Illegal purchase of firearms within the US, often orchestrated by straw purchasing cells at the direction of cartels, fuels trafficking into Mexico (ATF, 2021).
