Recent U.S. trade developments have created new layers of uncertainty for global companies that rely on international supply chains, imported components, or cross-border market strategies. In February 2026, the U.S. Supreme Court struck down a broad swath of tariffs imposed under the International Emergency Economic Powers Act (IEEPA), ruling that the president does not have unilateral authority to levy wide-ranging import taxes under that statute.
But rather than signaling a return to stable trade policy, this decision has been followed by a rapid recalibration of tariff strategy, including the announcement of a new global tariff of up to 15 percent that applies to most imports under a different legal framework.
What Changed?
The Supreme Court’s decision invalidated the prior emergency-based tariffs — a dramatic shift that ended an unprecedented executive use of tariff authority.
At the same time, the administration responded by invoking other statutes (like Section 122 of the Trade Act of 1974) to impose a temporary 15% tariff across the board. These replacement tariffs are legally permissible but come with statutory limits (e.g., a 150-day period unless extended by Congress) and highlight a broader pivot toward more formal trade authorities.
What This Means for Doing Business in the U.S.
1. Policy Uncertainty Is Still the Norm
Even though one set of tariffs was struck down, uncertainty remains high. The new 15% tariff regime is temporary and may evolve or be replaced depending on legal and congressional action. Businesses, investors, and supply chain partners are left to interpret overlapping laws and shifting rules, making planning difficult.
Uncertainty in tariff policy affects strategic decisions including:
Without clarity, companies may delay hiring, delay expansion, or slow product introductions — behavior that ultimately affects competitiveness.
2. Imported Inputs Have Higher Cost Risk
Even with the old tariffs struck down, effective tariffs remain elevated due to the new 15% surcharge and other existing trade duties. This means companies that rely on imported components still face increased landed costs.
These higher tariffs can:
For manufacturers selling into the U.S., this creates a more challenging competitive landscape compared to locally sourced suppliers.
3. Refunds and Retroactive Impacts Are Still Unclear
Many companies that paid previous tariffs are seeking refunds, and legal suits are underway. But the mechanism and timeline for refunds remain uncertain — which means navigating both short-term disruption and long-term financial ambiguity.
This creates challenges in:
Why Localization Matters Now
With tariff volatility and shifting trade policy, localization — meaning moving content, final assembly, or even part manufacturing into the United States — becomes more than a supply chain optimization tactic.
Localization helps companies:
For international companies, including those based in Asia and Europe, tariff uncertainty is a strategic risk that can be managed through thoughtful localization. Instead of reacting to trade policy changes after the fact, companies can proactively structure their market entry and product support in ways that are resilient to policy shifts.
