Chinese National Sentenced to 15 Years in Prison for Conspiring to Sell Oxycodone on the Darknet

PHILADELPHIA – United States Attorney David Metcalf announced that Zhengchang Huang, aka “chinodrug,” Chihwei Lim, and Yang Yong, 34, a Chinese national who had been legally residing in Kent, Washington, was sentenced today to 180 months’ imprisonment, three years of supervised release, and a $1 million fine by United States District Judge Michael M. Baylson for conspiracy to distribute oxycodone. Judge Baylson also ordered the forfeiture of nearly 200 Bitcoins, worth approximately $22 million as of today, deemed to constitute or derive from the proceeds of Huang’s criminal conduct.

The defendant was charged by indictment in April 2024 and pleaded guilty this February.

As detailed in court filings and statements, Huang led a conspiracy to operate as the drug vendor “chinodrug” from the U.S. and abroad. Through the darknet, encrypted peer to peer communications, and other means, Huang and his co-conspirators in Asia and the United States sold millions of dollars of Schedule II controlled substances, primarily oxycodone, to U.S. buyers. The drugs were smuggled in from China using Huang’s large international network. They were later advertised and sold on the dark web.

These illegal narcotics were shipped via U.S. mail to customers in multiple states, including the Eastern District of Pennsylvania, in exchange for virtual currency. Evidence in the case indicates that, from 2018 through early 2025, the “chinodrug” organization shipped more than 15,000 suspected opioid parcels from Washington State to U.S. customers across the country, generating millions in illicit revenue.

This case was investigated by Homeland Security Investigations, the United States Postal Inspection Service, and the Drug Enforcement Administration and prosecuted by Assistant United States Attorney Jason Grenell.
