US Tariff Impact on Small Molecule Injectable Drugs Market
The imposition of U.S. tariffs on pharmaceutical imports is expected to significantly impact the small molecule injectable drugs sector, particularly the generic drug market. Generic injectable drugs account for a large portion of hospital-administered medications and are vulnerable due to their low-profit margins. Although about 42% of finished dosage form (FDF) production for generic sterile injectables occurs domestically, a large share of active pharmaceutical ingredients (APIs) is sourced from countries like China and India.
Tariffs on imported APIs and finished products could drive up production costs for manufacturers. Given the tight contracts with group purchasing organizations (GPOs) and government programs such as Medicaid and 340B, passing these additional costs to consumers may be difficult. As a result, manufacturers might face financial strain, risking supply shortages or even market withdrawal of critical injectable drugs.
The U.S. pharmaceutical supply chain is heavily reliant on foreign sources, making it vulnerable to tariff-driven disruptions. India supplies a significant portion of generic drugs to the U.S., and tariffs could lead to reduced availability and higher prices. This situation could worsen existing shortages of essential medications, including cancer therapies and antibiotics, impacting hospitals and patient care nationwide.
An analysis by Ernst & Young suggests that a 25% tariff on imported pharmaceuticals could increase U.S. drug costs by approximately $51 billion annually. If these costs are transferred to consumers, drug prices could rise by about 12.9%. This increase would place additional financial pressure on healthcare systems and could reduce patient access to essential treatments.
