IMPACT OF U.S. & CHINA TRADE WAR

The ongoing U.S.-China trade war has materially reshaped the global steam turbine market by imposing hefty 25 % duties on core inputs like steel and aluminum, driving up casing, rotor, and auxiliary housing costs, and squeezing manufacturer margins. In May 2025 in Geneva, the U.S. agreed to lower its tariffs on Chinese goods from 145% to 30% while China agreed to lower its tariffs on U.S. goods from 125% to 10%, which established 90 days of tariff relief. If this agreement is not extended, then tariffs will automatically revert to their previous levels.

The prices of nickel and chromium-based alloys remain high because of indirect tariff risks, even though titanium and cobalt materials are not affected. The steam turbine market experiences a moderate degree of impact on cost structure and supply-chain resilience. Manufacturers will experience brief cost relief, but ongoing high expenses, together with supply chain unpredictability, prevent them from maintaining long-term pricing and production stability.
