HOUSTON — U.S. Immigration and Customs Enforcement and U.S. Customs and Border Protection seized 50,000 kilograms of di-cumyl peroxide, a chemical precursor used by drug traffickers to produce methamphetamines and other illicit narcotics, May 30 at the Port of Long Beach, California.

The shipment, which originated in China and was destined for the Sinaloa Drug Cartel in Mexico, was identified as a result of an initiative launched by ICE in 2019 that leverages the agency’s extensive expertise in illicit cross-border trade and sophisticated analytical tools and techniques to identify suspicious shipments of chemical precursors from China, India and other source countries that are destined for the drug cartels in Mexico.

“For far too long, the Mexican drug cartels have raked in billions of dollars at the expense of our local communities leaving nothing but addiction, death and despair in their wake,” said ICE Homeland Security Investigations Houston Special Agent in Charge Chad Plantz. “This initiative provides HSI with a game-changing method to stay one step ahead of the cartels by disrupting the flow of chemicals that they depend on to produce illicit narcotics.”

Since the initiative first launched, it has led to the interdiction of more than 1,700,000 kilograms of chemicals used to manufacture methamphetamines and fentanyl. Just this past March, it led to the seizure of nearly 44,000 kilograms of glacial acetic acid at the Port of Houston, which was also destined for the Sinaloa Cartel. In addition to preventing the chemicals from reaching the cartels, the initiative has also helped expose the location of clandestine drug labs in Mexico. In conjunction with Mexican authorities, 13 drug labs operated by the Chapitos faction of the Sinaloa Cartel have been located and eliminated since January 2025 as a result of the initiative.
