Stop Chinese Fentanyl Act of 2025

This bill amends U.S. sanctions law to target Chinese entities and officials involved in fentanyl trafficking. It redefines "foreign opioid trafficker" to include Chinese chemical companies or government officials (like those in the National Narcotics Control Commission) that fail to prevent fentanyl precursor trafficking or cooperate with U.S. efforts. Key mechanisms include requiring China to implement stricter chemical shipment labeling and "know-your-customer" procedures, extending sanctions periods from 5 to 10 years, and mandating annual presidential reports to Congress on drug trafficking emergencies. The bill explicitly excludes importation of goods from sanctions coverage.
