From April 28 to April 29, 2026, the Office of the United States Trade Representative (USTR) held a public hearing at the United States International Trade Commission (USITC) in Washington, D.C., marking a significant step forward in its Section 301 investigation covering 60 major U.S. trading partners.

This action represents the most extensive Section 301 review since the Section 301 tariffs on China (2018) and could have meaningful implications for global supply chains, shipping capacity, and import costs in the coming months.


Scope of the Investigation: Covering 99% of U.S. Imports

The investigation includes approximately 60 economies worldwide, among them:

Together, these partners account for over 99% of total U.S. imports, making this one of the broadest trade policy reviews in recent history.

Importers may accelerate shipments before tariff implementation, increasing short-term transport demand.

2. Capacity Tightening

Higher shipping volumes could lead to:

3. Freight Rate Volatility

Ocean freight markets may experience price fluctuations as demand shifts across trade lanes.


What This Means for Global Buyers and Project Developers

For companies sourcing overseas products—including modular buildings, container housing, steel structures, and construction systems—these developments highlight the importance of:

Advance preparation can help minimize cost uncertainty and delivery disruptions.
