- The United States revised Section 232 tariffs affecting industrial and agricultural equipment imports.
- New incentives encourage greater use of domestically produced steel and aluminum through 2027.
On June 1, United States President Trump signed a proclamation amending Section 232 national security tariffs applicable to selected aluminum, steel, and copper imports. The updated measures introduce revisions to tariff rates for specific equipment categories while also creating incentives designed to increase the use of domestically produced steel and aluminum in imported capital equipment. The changes are intended to support investment and manufacturing activity while maintaining existing national security trade measures.
Under the revised framework, tariffs on agricultural equipment such as combines and harvesters, along with residential heating, ventilation, and air conditioning equipment, have been reduced from 25% to 15%. The adjustment applies to a broad range of products covered under the proclamation and represents a targeted reduction intended to support affected industries while retaining import duties on strategic materials and equipment categories.
The proclamation also expands the scope of industrial equipment eligible for the 15% tariff treatment. Mobile industrial equipment, including bulldozers and forklifts, has been added to the existing category of industrial equipment subject to the reduced tariff rate when imported from countries covered by applicable trade agreements. This expansion broadens the range of machinery that can benefit from the revised duty structure while maintaining differentiated treatment based on trade partner status.
Another significant component of the order is the introduction of incentives aimed at encouraging greater utilization of domestically produced materials. Foreign manufacturers can qualify for a preferential 10% duty rate if their imported capital equipment contains at least 85% U.S. melted and poured steel or U.S. smelted and cast aluminum by weight. The measure is intended to strengthen demand for domestic metal production while encouraging international suppliers to integrate more U.S.-sourced materials into their products.
Key Tariff Changes Under the Updated Section 232 Proclamation
| Category | Previous Duty | Updated Duty |
|---|---|---|
| Agricultural Equipment | 25% | 15% |
| Residential HVAC Equipment | 25% | 15% |
| Qualified Capital Equipment with 85% U.S. Steel/Aluminum Content | Variable | 10% |
| New Steel and Aluminum Derivative Products | Not Covered | 25% |
Annexes accompanying the proclamation provide additional details regarding product classifications and associated tariff modifications. The latest update introduces two new categories of steel and aluminum derivative products that will now be subject to 25% import duties. These newly covered categories include steel racks and aluminum lithographic plates, expanding the list of derivative products falling under Section 232 tariff measures.
The revised tariff structure will take effect for goods imported into the United States or withdrawn from bonded warehouses after 12:01 a.m. EST on June 8. The measures are described as temporary and are scheduled to remain in place until December 31, 2027. According to the proclamation, the objective is to encourage near-term investment decisions while promoting increased use of domestic steel and aluminum within global manufacturing and supply chains.
