US Tariff Policy Casts Shadow on Global Clinical Trials Market: Sponsors, CROs Reassess Cost Structures

Washington D.C., July 2025 — As the United States ramps up tariffs on pharmaceutical ingredients and medical supplies sourced from China and other emerging economies, the ripple effects are beginning to shake the foundation of the global clinical trials industry. With the Biden administration maintaining and expanding tariffs originally imposed under Section 301, the impact on clinical trial budgets, supply chains, and international site selection is now being felt across sponsors and Contract Research Organizations (CROs).

Tariffs and Trials: What’s at Stake
The clinical research ecosystem — which heavily depends on a complex global supply chain of drugs, devices, reagents, and data infrastructure — is particularly sensitive to trade disruptions. In 2024, the U.S. Trade Representative (USTR) expanded tariff coverage on APIs (active pharmaceutical ingredients), lab reagents, plastic consumables, and certain Class I medical devices used in trial protocols.

These goods, which once flowed freely from low-cost manufacturers in China, India, and Southeast Asia, now face tariffs ranging from 15% to 25%. According to the Biotechnology Innovation Organization (BIO), such tariffs have inflated input costs for early-phase trials by as much as 8% in some cases, pushing trial sponsors to reevaluate site feasibility and logistics.

“We are seeing mid-sized biotech sponsors freezing or postponing trials not because of regulatory issues, but due to inflated operational costs caused by tariffs,” said Lisa Cordell, VP of Clinical Operations at a leading U.S. CRO.

Global Footprint Under Pressure
India and China — which collectively host nearly 35% of global clinical trials — have been key nodes in decentralized trial strategies due to their lower patient recruitment costs and operational flexibility. However, tariffs on drug packaging, electronic monitoring equipment, and raw materials are causing sponsors to look toward alternate sites in Eastern Europe, Latin America, and even within U.S. borders.

While some U.S. sites benefit from reshoring trends and increased investment in domestic trial infrastructure, the overall pipeline could slow due to budget constraints, especially in early-stage oncology and rare disease trials where the cost per patient is already steep.

Investment and Innovation at Risk
A June 2025 report from EvaluatePharma notes that average per-patient trial costs in the U.S. rose by 12% compared to 2023, driven in part by tariff-related supply price hikes. Add to this the increased regulatory compliance costs (post-COVID), and it’s clear why smaller biotech startups — often reliant on VC funding — are trimming their R&D pipelines.

Venture capitalists are now urging portfolio companies to consolidate trials or shift more phases offshore to mitigate cost exposure. Ironically, this leads to a paradox: tariffs designed to reduce reliance on foreign medical products may, in the short term, incentivize greater offshore activity in clinical operations.

CROs Navigate Uncertainty
For global CROs like IQVIA, ICON, and Parexel, managing the crossfire of tariffs, inflation, and geopolitical risk is now central to client strategy. Several CROs are exploring tariff-friendly “buffer hubs” in countries like Singapore and UAE — locations that allow for supply chain rerouting and localized warehousing to avoid high-duty corridors.

Many CROs are also digitizing workflows (e.g., eConsent, remote site monitoring, protocol automation) to offset rising physical costs and reduce trial duration.

“Digital transformation is no longer optional — it’s a strategic shield against global cost volatility,” said Anita Rhodes, Director of Global Trials at Parexel.

Outlook: Strategic Realignment Ahead
While the clinical trials industry is resilient, the ongoing tariff regime is expected to accelerate several long-term shifts:

• More regionalized supply chains to reduce cross-border dependencies.
• Increased use of digital and decentralized trial models to contain costs.
• Site selection strategies that favor low-tariff geographies with fast IRB/ethics approvals.
• Potential FDA policy adjustments to accommodate sponsor pressures.

Final Word
The U.S. tariff impact on clinical trials underscores a broader recalibration in how life sciences companies design, fund, and execute research. While innovation won’t stall, its geography and economics are evolving — and stakeholders across pharma, CROs, regulators, and patients will need to adapt.
