The Operation in Houston Was the Largest Seizure of Such Chemicals Ever by U.S. Law Enforcement
More than 300,000 kilograms of chemicals used to produce methamphetamine and intended for clandestine labs controlled by the Sinaloa Drug Cartel in Mexico were seized this week by agents with the U.S. Department of Homeland Security’s Homeland Security Investigations (HSI) at the Port of Houston, announced U.S. Attorney for the District of Columbia Jeanine Ferris Pirro and Acting Director Todd Lyons of U.S. Immigration and Customs Enforcement.
“This is the largest seizure of precursor chemicals used to manufacture methamphetamine in U.S. history,” said U.S. Attorney Pirro. “China was sending over 700,000 lbs, on the high seas to the Sinaloa Cartel before my office seized them. Because President Trump and Secretary Rubio declared the Sinaloa Cartel a Foreign Terrorist Organization, we can now strike faster and hit harder.”
“These many barrels of precursor chemicals are directly linked to one of the most dangerous and deadly terrorist networks, the Sinaloa Cartel. It’s one of the most violent and brutal terrorist organizations in the world. They are responsible for countless deaths, devastation, and destruction of communities in the U.S. and abroad,” said Director of Field Operations Jud Murdock of Customs and Border Protection, Houston. “This represents one of the largest interdictions of its kind in history and highlights the critical role of collaboration and intel sharing in combating threats posed by drug trafficking organization and terrorist groups.”
The chemicals, which originated in and were sent from China, could have been used to produce nearly 190,000 kilos of methamphetamine – worth about $569 million if they had reached their intended destination. Instead, agents seized six shipping containers of benzyl alcohol, a solvent used in the manufacture of pharmaceuticals, weighing 164,880 kilos and six shipping containers of N-methyl formamide, another liquid organic solvent, weighing 151,560 kilos.
To put in perspective the impact of this seizure, in Fiscal Year 2024, U.S. Customs and Border Protection (CPB) seized a total 78,925 kilos of methamphetamine along the entire southwest border. In order to transport the chemicals from port to a secure HSI storage facility, it took twenty-four, 18-wheeler trucks to transport the sheer volume of precursor chemicals.

The U.S. Attorney’s Office for the District of Columbia obtained the seizure warrant that provided the legal authority to seize the chemicals. Because the Administration designated the Sinaloa Cartel as a Foreign Terrorist Organization on January 20, 2025, the designation provided federal prosecutors in the District the authority to execute the seizure under the terrorism forfeiture provision.
Joining in today’s announcement were Special Agent in Charge Chad Plantz of Homeland Security Investigations, Houston; Director of Field Operations Jud Murdock of Customs and Border Protection, Houston; Acting Special Agent in Charge William Kimbell of the Drug Enforcement Administration, Houston; and FBI Special Agent in Charge Douglas Williams of the Houston Field Office.
The matter is being prosecuted by the U.S. Attorney’s Office for the District of Columbia as part of its Cartel Elimination effort, a collaboration between the office’s National Security section’s Threat Finance Unit (TFU) and Violent Crime and Narcotics Trafficking (VCNT) section.
The effort is also a part of the Attorney General’s February 5, 2025 directive, calling for the total elimination of cartels and transnational criminal organizations by harnessing the resources of the Department of Justice and empowering federal prosecutors throughout the country to work urgently with the Department of Homeland Security and other parts of the government toward the goal of eliminating these threats to U.S. sovereignty.
