U.S. Doubles Tariffs on Steel and Aluminum Imports to 50% – What Shippers Need to Know

Radius International Recaps the June 4th Policy Shift and Its Impact on Global Supply Chains

On June 4th, 2025, the U.S. government officially doubled tariffs on imported steel and aluminum, raising duties from 25% to 50%. The move, announced by former President Trump, was positioned as a measure to strengthen domestic manufacturing but has triggered significant consequences for global importers and supply chains.

What Changed

The tariff hike immediately impacted a wide range of industries, including construction, automotive, energy, and electronics. Importers relying on foreign-sourced steel and aluminum materials faced rising landed costs, tighter margins, and the need for rapid re-evaluation of their sourcing strategies.

Radius International worked closely with clients ahead of the implementation date to identify exposure, reroute shipments where possible, and plan for longer-term compliance solutions.

Regulatory Updates & CBP Implementation

While the U.S. Customs and Border Protection (CBP) had not issued full guidance at the time of the announcement, the regulation took effect on any qualifying steel or aluminum shipments entered for consumption on or after 12:01 a.m. ET on June 4th.

Shipments already in transit prior to that date may qualify for exemptions, but determinations depend heavily on cargo documentation, lading dates, and entry filing status.

How Radius Supported Clients

Throughout the transition, Radius International’s compliance team:

  • Audited tariff codes and product classifications
  • Advised on bonded warehouse solutions to defer duties
  • Assisted in reworking documentation to support claims of origin
  • Monitored developments and shared real-time guidance with clients

We remain available to assist with post-entry corrections, protests, and strategic planning for future shipments that may be impacted by this or similar trade enforcement actions.
