On 1 June 2026, President Donald Trump signed a new Proclamation further modifying the U.S. Section 232 tariff regime applicable to steel, aluminium and copper imports. The accompanying White House Fact Sheet indicates that the Administration is seeking to balance national security objectives with the needs of downstream manufacturers, farmers and infrastructure projects that rely on metal-intensive equipment.
The latest measure does not remove the core Section 232 framework. Commodity-grade steel, aluminium and copper products remain subject to the existing 50% tariff regime, while many derivative products continue to face additional duties. However, the Administration has introduced targeted relief for selected categories of agricultural equipment, industrial machinery and material-handling equipment that are considered critical to domestic economic activity.
Under the revised framework, certain agricultural and industrial equipment previously subject to higher Section 232 duties will be eligible for a reduced 15% tariff rate through 31 December 2027. In addition, imported products manufactured with at least 85% U.S.-origin steel, aluminium or copper by weight may qualify for a reduced 10% tariff rate. These changes are intended to encourage the use of domestically produced metals while reducing cost pressures on U.S. manufacturers and farmers.
From a trade compliance perspective, the announcement further increases the complexity of the Section 232 landscape. Importers will need to carefully evaluate product classification, derivative product coverage, country of origin, and the percentage composition of U.S.-origin metal content to determine eligibility for preferential treatment. The revised rules are also likely to increase documentation and recordkeeping requirements, particularly for companies seeking to substantiate the 85% U.S.-metal threshold.
The development highlights the continued evolution of Section 232 measures from a traditional national security tool into a broader industrial policy instrument aimed at strengthening domestic manufacturing while selectively mitigating downstream economic impacts.
