The recent US Supreme Court ruling striking down key tariffs imposed under emergency powers has reshaped the landscape of US trade policy, but it has not brought clarity. Instead, it has opened a new phase of uncertainty, with questions emerging around refunds, legal authority and the future direction of tariff policy.
In a 6–3 decision, the Supreme Court ruled on February 20, 2026 that the International Emergency Economic Powers Act (IEEPA) does not give the president authority to impose broad tariffs, reaffirming that tariff powers rest with Congress.
The decision invalidates a significant portion of recent tariff measures imposed by the Trump Administration, but crucially, it does not automatically resolve what happens next. Many existing tariffs imposed under other legal frameworks remain in place, and the broader US trade strategy is still evolving.
Will companies seek refunds?
One of the most immediate consequences is the question of tariff refunds. The ruling potentially opens the door to tens or even hundreds of billions of dollars in repayments to importers who paid duties under the invalidated measures.
However, the process is far from straightforward. Courts have recently declared that all IEEPA-affected entries will be in scope for relief, but the timing of these refunds are still uncertain.
Companies are taking different approaches, with some actively pursuing claims, while others are weighing the cost and complexity of litigation against uncertain outcomes. The result is a fragmented and evolving legal landscape.
Alternative tariff tools remain available
While the ruling limits one legal pathway, it does not eliminate the US government's ability to impose tariffs altogether.
In fact, the administration has already signalled it may pursue alternative statutory routes, including:
- Section 301 of the Trade Act (targeting unfair trade practices)
- Section 232 (national security-based tariffs)
- Section 122 (short-term tariffs to address balance-of-payments concerns)
The immediate response from policymakers suggests that tariffs will continue to play a central role in US trade policy, but through different mechanisms.
A more complex and uncertain policy environment
Rather than simplifying trade policy, the ruling may actually increase complexity. In social media post shared after the ruling, Donald Trump said: “During the next short number of months, the Trump Administration will determine and issue the new and legally permissible tariffs." With multiple legal pathways now in play, companies face a more fragmented environment where tariffs may:
- Vary by sector, country or policy objective
- Be introduced or removed more frequently
- Require closer monitoring of legal and regulatory developments
This creates challenges for planning, pricing and supply-chain strategy, particularly for businesses exposed to multiple markets.
What this means for global trade
In the short term, companies may benefit from potential refunds or reduced duties. But in the longer term, the shift toward alternative tariff tools and increased legal scrutiny is likely to create a more dynamic and less predictable trade environment.
For businesses, this means:
- Monitoring multiple tariff regimes simultaneously
- Preparing for rapid policy changes
- Incorporating legal and geopolitical risk into trade strategy
As policymakers explore new legal avenues and companies navigate refund claims, trade policy is entering a new phase defined by uncertainty, complexity and continued reliance on tariffs as a strategic tool.
