What this bill does
In plain words · AI-written from the official summaryTracks risks in America's drug supply chains
The FDA would maintain a list of medicines the U.S. needs to have available at all times, including those for emergencies, chronic illnesses, and military use. The agency would regularly assess risks in how these drugs are made and sourced, then report findings to Congress about potential vulnerabilities, foreign suppliers, and manufacturing capacity. Other federal agencies would also track and monitor these supply chains to spot problems.
How it affects you
This bill doesn't directly change medicines you can get or what you pay for them. It mainly works behind the scenes to help the government keep better track of which essential drugs might be at risk of shortage and where they come from, so policymakers can address supply problems before they affect patients.

Mapping America’s Pharmaceutical Supply Act or the MAPS Act
This bill requires the Food and Drug Administration (FDA) to continually update its essential medicines list and identify risks and vulnerabilities in the associated supply chains.
In 2020, in response to an executive order, the FDA published a list of essential medicines deemed medically necessary to have available at all times. The bill requires the FDA to update and maintain this list to include drugs and ingredients (1) related to responding to public health threats and emergency incidents, (2) of greatest priority for providing health care and at high risk of shortage, (3) the shortage of which would adversely affect patients with chronic conditions, and (4) that the Department of Defense (DOD) determines to be critical for military preparedness. The FDA must update the list at least every two years.
Also, the bill requires the FDA to conduct a risk assessment of the supply chains for drugs and ingredients on the list and annually report its findings to Congress. The assessment must include information about key manufacturing materials, drugs with primarily foreign suppliers, manufacturing capacity, relevant public health and national security risks, and risk mitigation strategies.
Additionally, the Department of Health and Human Services, in coordination with other agencies, must map and monitor relevant supply chains to identify vulnerabilities and provide an annual status report to Congress.
Finally, DOD must report to Congress every 180 days on the drugs DOD purchased that were manufactured in or sourced from China.
