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 classification covers specific cast-iron parts intended for use with spark-ignition internal combustion piston engines, including rotary engines. Crucially, these parts must not have undergone any significant processing beyond basic cleaning. Acceptable machining is limited to operations that remove casting imperfections such as fins, gates, sprues, and risers, or those necessary for positioning the part in subsequent finishing machinery. The primary function of these engines, as well as the vehicles they are destined for, must align with the specified subheadings within headings 8701, 8702, 8703, or 8704.

Distinguishing this category from its siblings, the "For marine propulsion engines" (8409.91.10.60) code specifically applies to parts for engines designed for marine applications, whereas this category has a broader scope for land vehicles and other non-marine uses. The "Other" (8409.91.10.80) category is a residual classification for parts not meeting the specific criteria of other subcategories within 8409.91.10, including this one.

As this is a leaf node within the Harmonized Tariff Schedule, there are no further subcategories to introduce. Classification under this code hinges on the material (cast-iron), the minimal processing applied, and the intended application with spark-ignition internal combustion piston engines utilized in the specified vehicle headings.
