Last updated: August 2026 dataReplacement and spare components for industrial, marine, and other non-aircraft gas turbines — including hot-section parts such as combustor baskets, transition pieces, and turbine wheels — are classified under SITC 71499. These parts are often manufactured from advanced nickel superalloys or ceramic thermal-barrier coatings, and their classification can overlap with headings for other machinery parts, making a detailed technical description critical at entry. Long-cycle procurement and OEM exclusivity arrangements are common in the power-generation sector, so importers sourcing from third-party or aftermarket suppliers should verify compatibility specifications and any applicable OEM licensing restrictions.

GRI (General Rules of Interpretation) and the relevant HTS chapter notes generally direct finished machine parts to the heading for the machine they serve rather than to a base-metal heading, provided the part is identifiable as suitable for use solely or principally with a specific machine. A detailed technical description and, where necessary, a CBP binding ruling will provide the most reliable classification outcome.
Parts made from steel or aluminum may independently attract Section 232 tariff exposure based on their own classification and country of origin, separate from any treatment applied to the complete turbine. Importers should conduct a line-by-line tariff analysis for each part number, particularly when sourcing from countries that do not have a Section 232 exclusion or quota arrangement with the US.
