Since the imposition of reciprocal tariffs on April 2, 2025, the United States has seen a layered tariff framework affecting microwave radar sensor imports. Initial reciprocal tariffs of 10 percent targeted goods from 60 countries, excluding China, Mexico, and Canada, and were set to escalate to country-specific rates by July 8, 2025. Shortly thereafter, the U.S. announced a sharp increase of reciprocal duties on Chinese-origin goods to 125 percent on April 9, amplifying total tariffs when combined with existing Section 301 and IEEPA levies for certain synthetic opioid-related products.

To alleviate supply chain pressures, a Presidential Executive Order on May 12 temporarily suspended 24 percentage points of ad valorem duties on Chinese-origin goods, reducing reciprocal rates to 10 percent through August 12, 2025. Concurrently, the USTR extended exclusions for 164 product categories-retaining cuts initially granted in May 2024-and added 14 solar manufacturing equipment items to the exempt list, effective June 1 through August 31, 2025. These policy adjustments have afforded manufacturers short-term relief, enabling continued import of critical components such as radar chipsets and modules without punitive duties.

Nevertheless, industry leaders report elevated component costs and supply volatility as enterprises recalibrate sourcing strategies and stockpile inventory ahead of tariff deadlines. With U.S.-China economic dialogues ongoing, including recent truce extension talks in Stockholm to avoid triple-digit tariff restoration, the situation remains fluid. Navigating this tariff environment has become a strategic imperative, compelling manufacturers and system integrators to diversify production footprints and seek local assembly partnerships to mitigate fiscal and operational risks.
