9902.15.44 - Connecting rods designed for use in compression-ignition internal combustion piston engines (diesel or semi-diesel engines) for vehicles of subheading 8701.20 or heading 8702, 8703, or 8704, each rod measuring at least 20 cm but not exceeding 120 cm in length, at least 10 cm but not exceeding 60 cm in width, and at least 5 cm but not exceeding 90 cm in height (provided for in subheading 8409.99.91)

This HTS category, 9902.15.44, specifically classifies connecting rods intended for use in compression-ignition internal combustion piston engines. These engines are commonly known as diesel or semi-diesel engines. The connecting rods must be designed for installation in vehicles falling under subheading 8701.20 (special purpose motor vehicles, e.g., tractor units for semi-trailers) or headings 8702 (motor vehicles for the transport of 10 or more persons), 8703 (motor vehicles for the transport of persons, including station wagons and racing cars), or 8704 (motor vehicles for the transport of goods). Crucially, these connecting rods are further defined by their physical dimensions, requiring a length of at least 20 cm but not exceeding 120 cm, a width of at least 10 cm but not exceeding 60 cm, and a height of at least 5 cm but not exceeding 90 cm.

The significance of this specific classification lies in its detailed technical and dimensional criteria, distinguishing it from more general categories of engine parts or connecting rods that might not meet these precise specifications or are not intended for the specified vehicle types. While other categories within Chapter 84 might cover general engine components, this 9902 subheading imposes temporary legislation or special provisions that target these particular connecting rods, likely due to trade agreements or specific import policies. It is important to note that this entry is a leaf node, meaning it does not have further subcategories. Therefore, classification within 9902.15.44 is final based on the criteria outlined in its description.
