United States Drug Enforcement Administration

WASHINGTON - China’s Ministry of Public Security last week announced scheduling controls on two fentanyl precursor chemicals - NPP and 4ANPP, substances that can be used to make illicit drugs. The scheduling controls will take effect on February 1, 2018 and is the result of the ongoing collaboration between the Drug Enforcement Administration and the Government of China and their shared commitment to countering illicit fentanyl-class substances.

“Fentanyl compounds significantly contribute to the current opioid crisis in the United States. By stemming the chemicals used to make these substances, this latest Chinese scheduling action will help save lives,” said DEA Acting Administrator Robert W. Patterson. “This scheduling action is an important step and a testament to the progress our countries are making together in addressing this epidemic.”

DEA and Chinese officials maintain frequent contact to collaborate and share data on the threat from fentanyl-class substances and their impact on the United States. Information-sharing includes scientific data, trafficking trends, and sample exchanges. This dialogue has resulted in improved methods for identifying and submitting deadly substances for government control.

The Chinese Government previously controlled four fentanyl-class substances - carfentanil, furanyl fentanyl, valeryl fentanyl, and acryl fentanyl - which took effect on March 1, 2017, and another four new psychoactive substances/fentanyl-class substances - U-47700, MT-45, PMMA, and 4,4’ DMAR - which took effect on July 1, 2017.
