Chinese National and Las Vegas Man Charged With Importing Protonitazene
A federal grand jury in the Southern District of Florida indicted a Chinese national and a Las Vegas resident for conspiring to import protonitazene, a potent synthetic opioid, and distribute it disguised as counterfeit pills. The charges trigger mandatory minimum sentences and signal continued U.S.-China law enforcement cooperation on fentanyl-class substances.
koreaherald.comA Chinese national and a Las Vegas man face federal charges for their alleged roles in a scheme to import large quantities of protonitazene into the United States and distribute the synthetic opioid in counterfeit pills.
The indictment, returned in the U.S. District Court for the Southern District of Florida, names the two defendants in a conspiracy to import and distribute protonitazene, according to a May 11, 2026, press release from the U.S. Department of Justice. Protonitazene belongs to the nitazene class of synthetic opioids, which the DEA has identified as significantly more potent than fentanyl.
The charges stem from an investigation by the Drug Enforcement Administration and the U.S. Postal Inspection Service. The People’s Republic of China’s Ministry of Public Security provided assistance, the department said. The case forms part of the Heroin Signature and Trafficking Program, known as HSTF.
The indictment alleges the defendants arranged shipments of protonitazene that reached the United States and were pressed into pills designed to mimic legitimate prescription medications. Federal law sets a mandatory minimum sentence of five years and a maximum of 40 years for conspiracy to import a Schedule I controlled substance such as protonitazene.
Additional counts for distribution of the substance carry identical penalty ranges.
The charges change the legal status of the two named individuals from unindicted targets to federal defendants required to appear in the Southern District of Florida. If convicted, each faces potential fines up to $5 million in addition to prison time. The case now moves to pretrial proceedings, including possible extradition or transfer if either defendant is not already in custody.
Downstream, prosecutors must disclose evidence gathered through the postal service’s mail interdiction and any electronic surveillance. The DEA must continue tracking protonitazene supply chains that originate in chemical laboratories in China. The Ministry of Public Security’s involvement means U.S. agencies will likely request further cooperation on precursor chemical controls and suspect identification.
Sentencing guidelines will require the court to calculate drug quantities involved, directly affecting prison terms once any guilty pleas or verdicts occur.
This indictment follows repeated federal actions against nitazene-class substances. The DEA placed protonitazene and related nitazenes into Schedule I in 2022 after documenting their appearance in seized pills and overdose clusters. The HSTF program has produced similar indictments involving Chinese chemical exporters and U.S. distributors in the past three years.
Congress has separately required annual reporting on bilateral counternarcotics efforts with China under legislation passed in 2019.
