8409.91.50.10 - Connecting rods

This HTS category, 8409.91.50.10, specifically classifies connecting rods intended for use with spark-ignition internal combustion piston engines, including rotary engines. These connecting rods are designed to be installed in vehicles falling under subheadings 8701.21 through 8701.29, or headings 8702, 8703, or 8704. The primary function of a connecting rod is to transmit power from the piston to the crankshaft in an engine.

This classification distinguishes itself from its siblings by its specific product identification. While 8409.91.50.81 covers steel forgings within this broader engine parts category, and 8409.91.50.85 encompasses all other miscellaneous parts not otherwise specified, 8409.91.50.10 is precisely for connecting rods. The key differentiating factor is the identification of the specific component – the connecting rod – and its intended application within certain classes of vehicles and engine types.

As a leaf node, this classification represents the most granular level for connecting rods meeting these specific criteria. Therefore, there are no further subcategories to introduce. Classification at this level is determined by the precise identification of the part as a connecting rod and its confirmed suitability for installation in the specified vehicle categories and engine types outlined in the parent headings.
