Two Chinese Chemical Company Executives Sentenced To 25 And 15 Years In Prison, Respectively, For Fentanyl Precursor Importation And Money Laundering Offenses

United States Attorney for the Southern District of New York, Jay Clayton, and Administrator of the U.S. Drug Enforcement Administration ("DEA"), Terrance C. Cole, announced that QINGZHOU WANG, a/k/a "Bruce," and YIYI CHEN, a/k/a "Chiron," were sentenced to 25 and 15 years in prison, respectively, for fentanyl precursor importation and money laundering offenses. WANG and CHEN, both nationals of China, were found guilty on February 3, 2025, following a two-week jury trial before U.S. District Judge Paul G. Gardephe, who imposed the sentences. WANG, who was also convicted of importing a methamphetamine precursor, was sentenced today, September 18, 2025, and CHEN was sentenced on August 22, 2025.

"American families are burying loved ones because of fentanyl and individuals like Qingzhou Wang and Yiyi Chen who unlawfully market and supply the ingredients to make it," said U.S. Attorney Jay Clayton. "There is no place to hide for those who callously fuel the fentanyl epidemic, and these sentences-which were only possible because of the extraordinary efforts of the career prosecutors in this Office and our partners at the DEA and abroad-prove it."

"These executives turned a Chinese chemical company into a pipeline of poison, shipping hundreds of kilos of fentanyl-related precursors into the United States, disguising them as everyday goods, and cashing in through cryptocurrency," said DEA Administrator Terrance Cole. "Americans were dying, but they kept selling. Thanks to DEA and our global partners, they now face justice, and this case sends a clear message: anyone, anywhere in the world who profits from American deaths will be found and held accountable."

As reflected in the Indictment, public filings, and the evidence presented at trial:

AMARVEL BIOTECH was a chemical manufacturer based in the city of Wuhan, in Hubei province, China, that exported vast quantities of the precursor chemicals used to manufacture fentanyl and its analogues.

During this investigation, AMARVEL BIOTECH and its principal executive, WANG, its marketing manager, CHEN, and a sales representative, FNU LNU, a/k/a "Er Yang," a/k/a "Anita" ("YANG"), shipped more than 200 kilograms of precursor chemicals used to make fentanyl and its analogues from China to the U.S. They shipped the precursors to the U.S. after being told that the chemicals would be used to produce fentanyl in New York, and then they agreed to supply multi-ton shipments of fentanyl precursors despite being told that Americans had died after consuming fentanyl made from the chemicals that the defendants had sold. In exchange, AMARVEL BIOTECH received tens of thousands of dollars in payment in cryptocurrency.

In or about November 2022, YANG began negotiating the sale of fentanyl and methamphetamine precursors to a DEA confidential source ("CS-1") posing as a fentanyl trafficker in Mexico with operations in the U.S. AMARVEL BIOTECH thereafter shipped from China to New York approximately 999.7 grams of the fentanyl precursor 1-boc-4-AP, approximately 1,002.6 grams of the fentanyl precursor 1-boc-4-piperidone, and approximately 893.6 grams of the methamphetamine precursor methylamine.

In or about March 2023, WANG and CHEN traveled from China to Bangkok, Thailand, to meet with an individual whom CS-1 represented was CS-1's boss but who was in fact another DEA confidential source ("CS-2"). During the meeting, WANG and CHEN discussed AMARVEL BIOTECH's ability to supply ton-quantities of fentanyl precursors to New York for CS-1 and CS-2's fentanyl manufacturing operation. After CS-2 stated that CS-2 wanted a different formula for manufacturing fentanyl and that several of CS-2's American customers had purportedly died, WANG and CHEN advised they had "a lot of customers in America and Mexico" who could provide technical assistance with fentanyl production.

After the March 2023 meeting in Bangkok, AMARVEL BIOTECH, WANG, CHEN, and YANG agreed to sell CS-1 and CS-2 approximately 210 kilograms of fentanyl precursors, again in exchange for payment in cryptocurrency. During an April 10, 2023, video call with WANG and CHEN, CS-2 stated that the approximately 210 kilograms of fentanyl precursors would be used to manufacture approximately 50 to 55 kilograms of fentanyl-an amount that, as noted above, could contain approximately 25 million deadly doses.

In or about May 2023, AMARVEL BIOTECH, WANG, CHEN, and YANG sent to the U.S. the shipment ordered by CS-1 and CS-2. On or about May 5, 2023, the DEA retrieved the precursor shipment from a warehouse near Los Angeles, California. Lab testing confirmed the presence of a precursor chemical for a fentanyl analogue. In an encrypted messaging group chat with CS-1, CS-2, WANG, and CHEN, YANG explained that "New York, the United States, has been strict in checking the precursors of the 'final product' some time ago, so for the sake of safety, this time it is sent to California."

In or about June 2023, WANG and CHEN traveled from China to Fiji to meet again with CS-2. During the meeting, WANG and CHEN discussed with CS-2 a multi-ton order of fentanyl precursor chemicals. WANG and CHEN also discussed the need to take additional measures to protect themselves from detection and interdiction of their shipments "because recently American government . . . seized some Mexican group and they followed the routes to China," where the U.S. Government found "our competitor in China"-an apparent reference to fentanyl-related charges filed in the Southern District of New York and announced in April 2023 against, among others, leadership of the Sinaloa Cartel and certain China-based precursor chemical company executives.

AMARVEL BIOTECH openly advertised online its sale of precursor chemicals for use in manufacturing fentanyl. Through its website and a host of other storefront sites, AMARVEL BIOTECH targeted precursor chemical customers in Mexico, where drug cartels operate clandestine laboratories and distribute finished fentanyl into and throughout the U.S., including by advertising fentanyl precursors as a "Mexico hot sale," guaranteeing "100% stealth shipping" abroad, and posting to its websites documentation of AMARVEL BIOTECH shipping chemicals to Culiacan, the home city of the Sinaloa Cartel, one of the dominant drug trafficking organizations in the Western Hemisphere and which is largely responsible for the massive influx of fentanyl into the U.S. in recent years.

AMARVEL BIOTECH also endeavored to thwart law enforcement interdiction of its precursor chemical shipments. AMARVEL BIOTECH advertised online the business's ability to use deceptive packaging-such as packaging indicating the contents are dog food, nuts, or motor oil-to ensure "safe" delivery of the illicit contents of such shipments. During this investigation, law enforcement seized approximately $900,000 in cryptocurrency from accounts tied to AMARVEL BIOTECH and domain names for 12 websites tied to AMARVEL BIOTECH.

In addition to their respective prison terms, WANG, 37, and CHEN, 33, both of China, were each sentenced to three years of supervised release. WANG was ordered to forfeit $67,168.25, and CHEN was ordered to forfeit internet domain names for 12 websites previously seized by law enforcement.

Mr. Clayton praised the outstanding efforts of the DEA's Special Operations Division Bilateral Investigations Unit. Mr. Clayton also thanked the DEA Bangkok Country Office, DEA Wellington Country Office, DEA Beijing Country Office, DEA Honolulu District Office, DEA New York Organized Crime Drug Enforcement Task Force Strike Force, DEA Riverside District Office, DEA Special Testing Laboratory, the DEA Southwest Laboratory, the Office of International Affairs of the Department of Justice's Criminal Division, the Royal Thai Police Narcotics Suppression Bureau, the Fiji Police Force Narcotic Bureau, the Fiji Office of the Director of Public Prosecutions, and the U.S. Attorney's Office for the District of Hawaii for their assistance.

This case is being handled by the Office's National Security and International Narcotics Unit. Assistant U.S. Attorneys Alexander Li and Kevin Sullivan are in charge of the prosecution, with assistance from Paralegal Specialist Sabrina Jim Munoz.
