On the Dash:
- U.S. expands steel and aluminum tariffs to 400+ imports, including auto parts and EV components.
- Tariffs cover $200B in goods and add a 50% duty on steel and aluminum content.
- Automakers face higher costs on exhaust parts and EV steel, raising pressure on pricing.
The U.S. Commerce Department announced Tuesday that it is expanding steel and aluminum tariffs to cover more than 400 additional product categories, a move that will affect over $200 billion worth of imports. The tariffs, effective immediately, include a 50% duty on the steel and aluminum content of affected goods, on top of existing country-specific tariffs for non-metal components.
The updated list includes railcars, motorcycles, wind turbines, mobile cranes, bulldozers, marine engines, heavy equipment, furniture and household appliances such as refrigerators, freezers and dryers. Significantly for the automotive sector, imported parts for exhaust systems, electrical steel used in electric vehicles, and other vehicle-related components are now subject to the higher rates.
The expansion comes after U.S. steelmakers, including Cleveland-Cliffs and Nucor, petitioned the administration to broaden protections to cover more products, particularly auto-related components. By closing what officials described as “avenues for circumvention,” the Commerce Department aims to strengthen domestic producers and further its efforts to revitalize the steel and aluminum industries.
Industry analysts estimate the policy shift will increase the overall effective tariff rate by roughly one percentage point. Evercore ISI noted that the revised measures apply to hundreds of product codes, signaling wide-reaching implications across sectors reliant on imported steel and aluminum.
Foreign automakers and suppliers had urged the department to exclude certain components, citing limited domestic production capacity. Tesla also lobbied against expanding tariffs on specialty steel used in EV drive units and wind turbines, warning that U.S. manufacturers could not yet meet demand. Despite these objections, the new rules were finalized without exemptions for those parts.
The decision adds new cost pressures on automakers and appliance manufacturers that depend on foreign-sourced inputs. For the automotive industry in particular, higher tariffs on exhaust system parts and EV-related steel could increase production costs and affect supply chains at a time when manufacturers are scaling electrification strategies.
The broader implications will likely be felt throughout the retail automotive sector, as higher material costs often filter down through suppliers to vehicle pricing.
