In March and April 2025, U.S. trade policy introduced a sweeping 25% ad valorem tariff on imported passenger vehicles, light trucks, and critical auto parts, invoking Section 232 of the Trade Expansion Act to safeguard national security interests. This tariff regime extends to finished vehicles effective April 3 and to specified components by May 3, imposing an additional duty atop existing MFN and Section 301 levies. Manufacturers and suppliers reliant on cross-border supply chains have since confronted elevated input costs and disrupted production planning.

Shortly thereafter, a provisional 90-day mutual tariff reduction agreement with China lowered reciprocal duties on Chinese-origin materials from 125% to 10%, offering temporary relief for key raw materials like indium tin oxide and specialized liquid crystal compounds. However, the concurrent tariff framework for vehicles and parts remains in place, creating a complex overlay of tariff tiers and exemptions under USMCA content certification processes.

In July 2025, the United States and Japan concluded a trade deal capping Japanese automotive tariffs at 15%, exempting them from the higher 25% rate and applying downward pressure on vehicles from other regions. This preferential arrangement provides competitive advantage for Japanese automakers while further fragmenting market access for non-USMCA producers. Collectively, these policy shifts are driving manufacturers to reassess production footprints, accelerate local content strategies, and pursue tariff mitigation through regional manufacturing alliances. The cumulative impact of U.S. tariffs in 2025 underscores the urgency for agile supply chain diversification and strategic sourcing of liquid crystal dimming film components.
