Further intensifying this framework, a June 3, 2025, proclamation elevated steel and aluminum tariffs to 50%, effective June 4. These measures preserve a 25% rate for the United Kingdom pending Economic Prosperity Deal negotiations and aim to counteract global excess capacity that threatens U.S. national security supply objectives.

Automotive parts suppliers have navigated a complex interplay of derivative tariffs, as steel content in components such as bumper stampings and leaf springs attracts additional duties. An April 2025 executive order introduced “non-stacking” provisions for automobile and auto parts tariffs, preventing simultaneous application of multiple steel-related tariffs and offering retroactive refunds for excess duties paid between March 4 and May 16, 2025.

Industry data reflect the heightened cost pressures: a March 2025 survey by the Vehicle Suppliers Association found 78% of respondents exposed to steel tariffs, with more than a third facing levies on both imported inputs and finished deliveries. This dynamic has elevated domestic sourcing strategies and underlined the need for proactive tariff mitigation and localized production agreements within North America.

Automotive-grade non-heat-treated steel demand spans an array of product types, each tailored to specific dimensional criteria and performance requirements. Cold drawn steel wire is categorized by diameter tiers, from sub-5mm precision wires to robust segments exceeding 10mm, serving applications from fine fasteners to heavy-duty springs. Cold rolled steel sheets, segmented by thicknesses under 1mm through to above 2mm, underpin lightweight body panels and structural reinforcements. Meanwhile, cold rolled steel strips vary across narrow, standard, and wide widths, enabling component designs from narrow suspension parts to wide chassis supports.

Applications for these steel types traverse body panels-doors, hoods, and roofs-that demand formability and surface quality; chassis components such as axles, control arms, and suspension springs that require fatigue resistance; and a spectrum of fasteners and springs, from bolts and nuts to coil and leaf springs, where precision and durability are paramount.

Steel grades further diversify the landscape, with carbon steel variants like SAE 1005 and SAE 1020 meeting general-purpose demands, alloy steels such as 4130 and 4140 offering enhanced tensile capacities, and dual phase steels, including DP500 and DP600, providing a balance of high strength and formability for safety-critical structures.

Vehicle type segmentation highlights distinct requirements: commercial vehicles, both heavy and light, leverage non-heat-treated grades for load-bearing frames, whereas battery and hybrid electric vehicles use these steels to offset battery mass. Passenger cars-from hatchbacks to sedans and SUVs-employ tailored steel segments to optimize ride performance and crashworthiness.

Manufacturing processes integrate cold drawing stages, from pre-drawing to final drawing, alongside cold rolling phases encompassing roughing and finishing, ensuring steel products achieve precise mechanical properties. Surface treatments ranging from hot-dipped galvanization to oiled and phosphate coatings further enhance corrosion resistance, with options like mineral or synthetic oils and iron or zinc phosphate tailored to end-use environments.
