For companies that paid these duties, particularly importers reliant on affected trading relationships, the cash refunds could provide a meaningful working capital boost in the near term. ---Washington has refunded roughly $100 billion in unlawful tariffs, but Trump has already moved to replace them with new duties under different legal authority. The refunded amount represents more than half of the $166 billion collected under tariffs the Supreme Court invalidated in a ruling handed down in February, according to Reuters. Tariffs have remained a central pillar of President Trump's trade and foreign policy agenda throughout his term, despite repeated legal challenges and criticism from economic analysts. Rather than scaling back tariff policy following the ruling, Trump escalated his trade agenda in response.
