About Duty Rates: Rates are divided into Column 1 and Column 2. Column 1 is subdivided into General (normal trade relations rates for all countries not eligible for special programs) and Special (preferential rates for countries with free trade agreements or preference programs). Column 2 rates apply to products from Cuba, North Korea, Belarus, and Russia. When no special rate exists for a classification, General rates apply.

Overview

This HTS classification covers specific parts intended for non-aircraft gas turbines. The defining characteristic of goods within this category is their material composition and the extent of their processing. Specifically, it includes parts that are primarily made of cast iron and have undergone minimal finishing. This processing is limited to basic cleaning operations and machining solely for the removal of casting imperfections such as fins, gates, sprues, and risers. Furthermore, machining may be permitted if it serves the sole purpose of preparing the part for subsequent finishing machinery operations, not for its functional integration into the turbine.

This category is distinct from its sibling, "Parts of aircraft turbines," which would encompass similar cast-iron components but specifically those destined for turbines used in aircraft. The distinction lies in the end-use application of the turbine. While the physical characteristics of the cast-iron part might be similar, its classification hinges on whether it is intended for a terrestrial or aerial application.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification within 8411.91.10.40 is determined by the material (cast iron), the limited nature of the machining (cleaning and preparation for further processing), and the fact that the parts are not for aircraft turbines. Examples of such parts could include housings or structural components for industrial gas turbines, in their initial cast and partially cleaned or prepped state.
