US pharmaceutical tariffs put Ireland’s Pharma sector on alert

In a major escalation of his protectionist trade agenda, U.S. President Donald Trump announced 100% tariffs on branded pharmaceuticals, affecting companies that have not yet begun U.S.-based manufacturing projects. The move has sent shockwaves through Ireland’s pharma sector, home to a significant concentration of American-owned factories.

Ireland has already seen a surge in exports in anticipation of trade disruptions. According to the Central Statistics Office, chemical and related product exports jumped 536% year-on-year to €23.9 billion in the first seven months of 2025. The announcement, however, left key questions unresolved, particularly regarding overlap with existing national tariffs and the EU-US trade agreement enacted last week.

Irish officials, including Foreign Minister Simon Harris, are reviewing the implications in coordination with EU colleagues. The EU-US Joint Statement, negotiated in August, establishes a 15% ceiling on tariffs for EU-originating pharmaceuticals, providing a level of certainty for exporters. European Commission officials emphasise that the agreement remains binding and continues to guide engagement on tariff exemptions and broader cooperation.

Industry bodies, such as the Irish Pharmaceutical Healthcare Association, warned that higher tariffs could disrupt global supply chains, increase costs, and undermine patient access and innovation. Analysts note the move aligns with Trump’s broader strategy of anchoring tariff authority within established legal frameworks, ahead of a Supreme Court hearing in November examining the legality of the administration’s global tariff regime.

The announcement underscores the fragile balance of transatlantic trade and the continuing need for Irish and EU firms to monitor regulatory developments closely.
