The FBI announced indictments against two Chinese pharmaceutical companies and six Chinese citizens in connection with a fentanyl precursor smuggling operation targeting the United States. The charges stem from Operation Box Cutter, an FBI-led multi-agency investigation focused on disrupting the global supply chain of fentanyl manufacturing chemicals, the Justice Department said.
Indictments Detail Charges and Parties Involved
A federal grand jury in Dayton, Ohio charged Shandong Believe Chemical Company and Shandong Ranhang Biotechnology, along with individuals Hanson Zhao, Gao Yanpeng, Xia Yi, Zhang Jian, Wang Zhoalan, and Zhang Chunhai. The defendants are accused of soliciting, negotiating, and securing payments for precursor chemicals and cutting agents used to produce fentanyl.
According to prosecutors, from July 2025 through January 2026, these individuals openly marketed, sold, and delivered various chemical precursors to U.S. customers and foreign drug traffickers. The payments were made via cryptocurrency, which was transferred to digital wallets before being deposited into foreign financial institutions.
Three of the defendants are further charged with selling chemical precursors and medetomidine—a potent animal tranquilizer used to cut fentanyl—to members of the Gulf Cartel, a group designated as a foreign terrorist organization by the U.S. State Department. The conspiracy allegedly involved manufacturing and distributing 400 grams or more of fentanyl mixture.
International Cooperation and Enforcement Efforts
The investigation received intelligence support from China’s Ministry of Public Security, which collaborated with the FBI to enhance understanding of the companies’ activities. FBI Operations Director Joe Perez highlighted this cooperation as key to advancing the case and sending a message to those involved in similar schemes.
FBI Director Kash Patel described Operation Box Cutter as a historic success marked by unprecedented indictments linking fentanyl supply chains to material support for terrorism. Patel referenced a 2025 visit to China, where he engaged with Chinese counterparts to tighten controls on fentanyl precursors, reinforcing joint efforts to curb the flow of these substances.
The Justice Department noted that fentanyl is frequently cut with medetomidine, which can increase the yield of fentanyl doses substantially, intensifying risks associated with street-level sales.
