In 2025, the United States implemented a sweeping series of tariff adjustments that have profoundly impacted small diameter metal hose supply chains. Presidential directives raised average applied tariff rates from 2.5 percent to 27 percent between January and April, before moderating to approximately 15.8 percent by June. These measures, enacted under the International Emergency Economic Powers Act, represent the most aggressive U.S. trade protectionism in decades, targeting steel, aluminum, copper, and broader categories through reciprocal rates.

Steel and aluminum inputs, foundational to corrugated hose cores and protective braids, were subjected to initial 25 percent levies on March 12, 2025, subsequently doubled to 50 percent in early June under a domestic-origin “melted and poured” requirement designed to close exemption loopholes. Meanwhile, a universal 10 percent tariff on all imports took effect April 5, augmenting duties for 57 major trading partners and raising the baseline cost of raw and semi-finished metal products.

For hoses containing copper, brass fittings, and specialty nickel-based alloys, these tariff layers have compounded material price volatility, with plumbing and fluid handling sectors reporting increases of 15 to 35 percent in finished component costs since the measures took effect. Supply constraints have led to extended lead times for custom assemblies, particularly in applications requiring exotic alloys for high-temperature or aggressive chemical environments.

Consequently, many manufacturers and end users are reevaluating sourcing strategies, exploring domestic alloy suppliers, and adjusting product designs to mitigate tariff impacts. Collaborative initiatives with regional fabricators and preference for U.S.-based steel and aluminum mills have emerged as interim solutions, though long-term stability hinges on evolving trade negotiations and policy clarity.
