The MAPS Act (Mapping America's Pharmaceutical Supply Act) is designed to protect America's health and national security by creating a comprehensive system to track and understand the supply chains for critical medicines. Here's what it does in practical terms: The government will maintain an official list of essential medicines—drugs that are crucial for responding to emergencies, treating chronic conditions, or supporting military readiness. This list will be updated at least every two years. The government will then conduct a detailed risk assessment of where these medicines come from and how they're made, identifying vulnerabilities like over-reliance on foreign suppliers, especially those from countries of concern. The bill also requires the Department of Health and Human Services to map out the entire supply chain for these essential medicines—from raw materials through manufacturing to distribution—using data analytics to spot potential problems before they become shortages. Additionally, the Department of Defense must report every six months on any drugs it purchases that contain ingredients made in China or are manufactured there. The goal is straightforward: make sure the federal government knows exactly where critical medicines come from and can quickly identify and fix problems that could threaten public health or national security.
