The Trump administration has identified a list of 167 steel derivatives to be added to the US Section 232 tariffs, according to Kallanish. These products include steel fasteners, welded angles, profiles and sections of iron or steel, bridges and bridge sections, gratings, meshes and fences, parts for agricultural machinery, and modular steel building blocks.
The administration believes that the growth in imports of some derivative steel products has led to a decrease in demand for domestically produced goods. As a result, they see the need to adjust the tariff to cover additional processed products, potentially imposing an additional ad valorem duty rate of 25%.
On February 10, US President Donald Trump ordered a 25 percent duty on all imports of steel and aluminum into the country, without any exceptions or exemptions. The new rates will come into effect on March 12, applying to steel and aluminum imported from various countries, including Canada, Brazil, Mexico, and South Korea. The U.S. Secretary of Commerce has 90 days to develop a procedure for including additional steel derivatives in the scope of the duty.
