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, 8407.90.90.10, specifically covers gas-powered internal combustion piston engines, including those fueled by natural gas or liquefied petroleum gas (LPG), such as propane. These engines operate on the principle of spark ignition, where a spark plug initiates combustion within a cylinder to drive a piston. The scope of this subheading is limited to engines that are not specifically classified elsewhere within the 8407 heading, and which are not designed for aircraft, or for compression-ignition (diesel) operations.

Distinguishing this category from potential siblings, the "Other engines" at this level would encompass engines that do not fit the more specific subheadings within 8407. For instance, if there were subheadings for engines of a particular displacement or intended use not covered here, this "Other" category would serve as a residual for any remaining spark-ignition piston engines. The inclusion of "gas (natural or liquid propane (LP)) engines" as the primary description in the subheading itself highlights a key distinguishing factor, focusing on the fuel type.

As 8407.90.90.10 is a leaf node, it has no further subcategories. Therefore, classification within this subheading relies on ensuring the engine meets the general criteria for spark-ignition internal combustion piston engines and specifically utilizes natural gas or LPG as its fuel source. It is crucial for importers and exporters to confirm the engine's design and primary fuel type to ensure accurate classification under this specific provision, preventing misclassification with other engine types or fuel sources not intended for this subheading.
