The Nitazene Sanctions Act aims to strengthen existing law by specifically addressing the trafficking of 2-benzylbenzimidazole opioids , known as nitazenes . These synthetic opioids are noted for their significant potency, often exceeding that of fentanyl, and can be produced globally using readily available precursor chemicals. The bill highlights concerns about chemical manufacturing companies in the People's Republic of China synthesizing these precursors and the potential for Mexican cartels to funnel them into the United States. To combat this threat, the Act requires the Secretary of State and the Attorney General to submit a report within 120 days. This report must detail China's role in nitazene precursor production, outline a plan for U.S. cooperation with China to reduce this production, and propose a strategy for working with European allies to stem the flow of nitazenes from China. The bill also explicitly amends the Fentanyl Sanctions Act to include nitazenes within its scope of targeted controlled substances. A significant provision expands the definition of "foreign opioid trafficker" under the Fentanyl Sanctions Act to include entities of the People's Republic of China that produce or distribute synthetic opioids and fail to prevent trafficking, as well as senior Chinese officials who aid such trafficking. The President is also empowered to impose sanctions on foreign government subdivisions, agencies, or financial institutions that knowingly contribute to opioid trafficking or support precursor industries. Finally, the Fentanyl Sanctions Act's duration is extended from five to ten years.
