Transnational Drug Trafficking: The Role of Mexican Cartels

Mexican cartels dominate opioid trafficking in the U.S. The Sinaloa Cartel and Jalisco New Generation Cartel (CJNG) control fentanyl, heroin, methamphetamine, and cocaine distribution. Sinaloa operates in 47 countries, while CJNG has a presence in all 50 U.S. states.

Fentanyl is the deadliest opioid, 50 times stronger than heroin. In 2024, over 21,000 pounds were smuggled from Mexico, compared to 50 pounds from Canada. Overdose deaths linked to fentanyl surpassed 110,000 in 2022. Cartels use chemicals from China to produce fentanyl in clandestine labs.

Cartels employ advanced smuggling techniques, disguising fentanyl precursors as legal shipments. Methods include hidden vehicle compartments, tunnels, and drones. In 2024, authorities seized 7,584 pounds of fentanyl precursors in Los Angeles alone.

Cartel violence has caused over 460,000 homicides in Mexico since 2006. Despite $3.5 billion in U.S. security aid, Mexico struggles to contain cartels due to corruption and the cartels’ military tactics. Law enforcement efforts remain hindered by internal compromises and cartel influence.

The U.S. has sanctioned 25 Chinese entities tied to fentanyl shipments. While Mexico faces pressure to crack down, internal challenges persist. Stopping transnational trafficking requires coordinated efforts between both nations.

Global Supply Chains: Importing Precursor Chemicals from China

The fentanyl crisis begins with chemical suppliers in China. These companies export precursor chemicals used by Mexican cartels to manufacture fentanyl.

Many of these chemicals are not classified as controlled substances. After China banned certain fentanyl analogs in 2019, traffickers switched to unregulated chemicals, sustaining the trade.

Cartels operate industrial-scale labs in remote areas to convert these chemicals into fentanyl. Major ports like Manzanillo and Lázaro Cárdenas serve as entry points for shipments before reaching these labs.

U.S. authorities sanctioned 24 Chinese firms in 2023 for exporting fentanyl precursors. In 2024, 7,500 pounds of precursors were seized at the Los Angeles port. Traffickers continue to adapt by shifting suppliers and smuggling routes.

China has tightened chemical regulations but enforcement remains inconsistent. Some suppliers operate through front companies and online platforms.

India is emerging as an alternative supplier of fentanyl precursors. As Chinese regulations increase, traffickers seek new sources to maintain production.

Trade Policies and Tariffs: Trump Administration's Measures to Disrupt Illicit Flows

In 2025, the Trump administration imposed tariffs targeting fentanyl supply chains. Policies included a 25% tariff on imports from Mexico and Canada and a 10% tariff on Chinese goods, affecting $1 trillion in trade. The tariffs aimed to disrupt illicit drug flows.

Most U.S. fentanyl originates in Mexico, where cartels use Chinese precursor chemicals. After China tightened fentanyl regulations in 2019, traffickers adapted, using alternative chemicals. The U.S. sanctioned 25 Chinese firms in 2023 to further disrupt these networks.

In 2023, authorities seized 21,100 pounds of fentanyl at the southwest border. Tariffs sought to increase costs for traffickers but raised concerns that cartels could bypass them through alternate routes.

Economic effects extended beyond drug enforcement. Mexico faced potential GDP losses of 4%. Canada responded with $155 billion in retaliatory tariffs. U.S. consumers saw increased costs, with car prices rising by $3,000 due to higher import expenses.

Some officials questioned whether tariffs could curb trafficking. Historically, enforcement has led traffickers to adopt new methods rather than stopping the drug flow. Cartel violence in Mexico persisted, with over 460,000 homicides linked to organized crime since 2006.

The Trump administration sought to elevate the Office of National Drug Control Policy (ONDCP) to cabinet status, signaling a stronger federal response. However, tariffs alone could not resolve the fentanyl crisis, which required international cooperation and domestic policy reforms.

International Cooperation and the Global Response to the Opioid Crisis

The opioid crisis demands global collaboration. The United Nations Office on Drugs and Crime (UNODC) and the World Health Organization (WHO) push for coordinated strategies to combat opioid misuse. Law enforcement agencies worldwide have partnered to dismantle trafficking networks.

China remains a focal point in fentanyl regulation. In 2019, Beijing imposed controls on fentanyl-related substances under U.S. pressure. However, traffickers adapted by modifying chemical structures. The U.S. sanctioned 25 Chinese firms in 2023-2024 for supplying fentanyl precursors. China has since engaged in discussions to enhance enforcement.

Mexico is central to the global fentanyl trade. The U.S. invested $3.5 billion in Mexican anti-narcotics programs, yet cartel violence continues. In 2024, Mexico extradited several cartel leaders to the U.S. Joint task forces have targeted major supply lines, but trafficking persists.

India plays a growing role in opioid production. While supplying legal medications, some shipments are diverted into illicit markets. In 2024, Indian authorities seized 560 kilograms of cocaine tied to international trafficking. India has strengthened regulations and increased cooperation with the UNODC.

Europe is also tackling synthetic opioids. Europol and Eurojust coordinated an operation in 2024 that arrested 44 people across 11 countries, disrupting fentanyl distribution networks. The European Union has boosted intelligence-sharing efforts to intercept shipments.

The Global Coalition Against Synthetic Drug Threats, led by the U.S., includes over 100 countries working to combat opioid-related deaths. The UNODC has strengthened border security in Central Asia to curb heroin trafficking. Japan funds customs training programs to detect opioid shipments. Africa balances restricting illicit opioids with maintaining access to medical pain relief.

Law enforcement alone is insufficient. Public health strategies are key to reducing demand. Canada and European nations have expanded harm reduction programs, including supervised consumption sites and naloxone distribution. In 2024, the U.S. increased funding for opioid treatment programs. Countries like Portugal advocate for integrating healthcare with law enforcement to tackle the crisis.

Despite ongoing efforts, traffickers exploit regulatory loopholes, shifting smuggling routes and introducing new synthetic opioids. A global, adaptive response is essential to combat the opioid crisis and prevent further devastation.
