Proclamation 10947

Adjusting Imports of Aluminum and Steel Into the United States

This proclamation doubles the existing Section 232 tariffs on steel and aluminum imports from 25% to 50% ad valorem, effective June 4, 2025. It modifies how Executive Order 14289's tariffs interact with these duties, subjects non-steel/non-aluminum content to reciprocal tariffs under EO 14257, mandates strict CBP compliance enforcement, and carves out the United Kingdom at 25% pending potential EPD implementation or quota adjustments after July 9, 2025.

Impact dates

  1. CBP shall issue authoritative guidance on declaration requirements and penalties

  2. Secretary may adjust UK rates to quotas or increase to 50% based on EPD compliance

  3. 50% steel and aluminum tariffs take effect; EO 14289 amendment effective; foreign trade zone rules change

Role pressure

  • ProtectiveDomestic producer50% tariffs provide substantial price support and competitive shield against low-priced imports; intended to raise capacity utilization to levels needed for national defense and sustained industry health
  • AdverseImportertariff doubling from 25% to 50% significantly increases cost of imported steel and aluminum; strict CBP content declaration requirements and severe penalty exposure raise compliance risk; no drawback available
  • AdverseDownstream manufacturerhigher input costs for steel and aluminum intensive production; non-steel/non-aluminum content now subject to additional EO 14257 reciprocal tariffs, creating layered duty exposure
  • MixedTrading-partner exportermost countries face 50% tariff; UK temporarily shielded at 25% with potential quota path, but faces snapback to 50% if EPD compliance fails

Exposure dates

  • 50% steel and aluminum tariffs take effect; EO 14289 amendment effective; foreign trade zone rules change
  • Secretary may adjust UK rates to quotas or increase to 50% based on EPD compliance

Who is ordered

Timeline

Immediate

  • 50% tariff takes effect June 4, 2025 at 12:01 a.m. EDT
  • EO 14289 amendment takes effect
  • foreign trade zone status rules change
  • strict CBP compliance guidance required

Near term (90d)

  • Secretary may adjust UK rates or impose quotas on/after July 9, 2025

  • potential HTSUS modifications via Federal Register notice

Long term

Risks & tensions

  • Significant downstream cost pressure on U.S. manufacturers dependent on steel/aluminum inputs
  • UK carve-out creates potential arbitrage and transshipment monitoring challenges
  • Content-only tariff application (steel in Ch.73, aluminum in Ch.76) requires complex origin and content verification, creating compliance burden and enforcement uncertainty
  • Interaction with EO 14257 reciprocal tariffs on non-steel/non-aluminum content may create cumulative duty complexity
  • Foreign trade zone 'privileged foreign status' rule change disrupts existing inventory planning
