DAYTON, Ohio — In a landmark legal move for the Southern District of Ohio, a federal grand jury has returned a sweeping indictment against two Chinese pharmaceutical companies and six Chinese nationals. The charges allege a massive conspiracy to traffic fentanyl precursors and—for the first time in the region—attempting to provide material support to a Mexican drug cartel officially designated as a foreign terrorist organization.
The indictment, announced today by U.S. Attorney Dominick S. Gerace II, is a major strike under Operation Box Cutter, a Homeland Security Task Force initiative aimed at dismantling the global supply chains fueling the American opioid crisis.
Targeting the Source of the “Cut”
According to federal prosecutors, the defendants openly marketed and sold chemical precursors and “cutting” agents intended for the mass production of fentanyl. Specifically, the group is accused of trafficking medetomidine, an animal tranquilizer up to 200 times more powerful than morphine.
By “cutting” fentanyl with this potent sedative, traffickers can increase the volume of a single kilogram of fentanyl twenty-fold, creating millions of lethal doses for street-level sale.
A Historic Legal Shift
The case marks a significant escalation in how the U.S. government treats transnational criminal organizations. Three of the defendants are charged with attempting to provide material support to the Cártel del Golfo (Gulf Cartel).
“We are going after the entire chain of supply,” said U.S. Attorney Gerace II. “From Mexican cartels and Chinese pharmaceutical companies to the high-level distributors on our streets.”
The “terrorist organization” designation stems from executive orders and designations made early in 2025, allowing prosecutors to pursue stiffer penalties for those aiding these violent groups.
The Defendants and the Scheme
The indictment names the following entities and individuals:
- Companies: Shandong Believe Chemical Company Pte Ltd. and Shandong Ranhang Biotechnology Co. Ltd.
- Individuals: Hanson Zhao, Gao Yanpeng, Xia Yi, Zhang Jian, Wang Zhoalan, and Zhang Chunhai.
The defendants allegedly used cryptocurrency to mask payments from U.S. customers, funneling the digital assets into overseas bank accounts to avoid detection by traditional financial monitors.
Penalties and Next Steps
The charges carry severe consequences:
- Narcotics Conspiracy: Minimum of 10 years to life in prison.
- Material Support to Terrorists: Up to 20 years in prison.
- International Money Laundering: Up to 20 years in prison.
The FBI’s Cincinnati Division noted that critical intelligence for this investigation was provided by China’s Ministry of Public Security, highlighting a rare but vital moment of international cooperation in the “Whole-of-Government” approach to stopping the flow of synthetic opioids.
