Under the proposed policy framework:Two-Year Grace Period: Generic drug imports will continue to face a 0% tariff.Phase-One Escalation: A 100% duty will take effect for one year following the grace period.Phase-Two Escalation: Tariffs will increase further to 200% on companies that fail to establish US-based manufacturing infrastructure.Patented, innovative, and branded therapies remain excluded from the generic tariff framework.Analyst Perspective: Near-Term Jitters vs. Long-Term RealitiesDespite the initial market sell-off, institutional analysts suggest the real economic impact on Indian generic drugmakers may be less severe than price reactions indicate.Significant Cost Advantages: India-based manufacturing remains 40% to 60% cheaper than domestic US production. Even under tariff pressures, US buyers rely heavily on foreign supplies, as over 90% of US generic prescriptions are currently imported.Long Lead Times: Building, inspecting, and securing regulatory approvals for new US manufacturing plants takes anywhere from 3 to 4 years, creating operational hurdles for rapid reshoring efforts.Mitigating Factors: Major producers like Sun Pharma, Dr. Reddy’s, and Cipla already operate US-based subsidiaries or maintain diversified portfolios in complex generics and specialty drugs, helping insulate their revenue bases from basic generic tariffs.Also Read :- ABSL AMC Q1 Results 2026: Net Profit Rises 12% YoY to ₹310 Crore, AUM Reaches ₹10.7 Lakh Crore
