Last updated: August 2026 dataBlades, rotors, nozzles, casings, and other replacement or OEM components for steam and vapor turbines serve the power generation, petrochemical, and industrial sectors. The high-alloy steels and nickel superalloys used in turbine hot-section parts give these components significant intrinsic value and make accurate valuation and classification critical. Turbine parts sourced from certain origins may be subject to Section 232 tariffs on steel and aluminum derivatives, and importers should evaluate whether the finished parts qualify as derivative steel or aluminum articles under applicable proclamations.

Turbine blades that are identifiable as parts suitable for use solely or principally in steam or vapor turbines are classified as turbine parts rather than as articles of nickel, regardless of their alloy composition. The principal-use test and the part's design specificity to the turbine application govern classification.
Turbine parts with significant steel or aluminum content may qualify as derivative steel or aluminum articles subject to Section 232 tariffs, depending on the HTS classification and the specific proclamation language in effect at the time of entry. Importers should review the current scope of Section 232 derivative product coverage and consult a customs broker to determine whether an exclusion request or alternative sourcing strategy is warranted.
