8409.99.92.10 - Connecting rods

This HTS classification, 8409.99.92.10, specifically designates connecting rods for use with engines falling under headings 8407 or 8408, with a particular focus on those intended for marine propulsion. Connecting rods are critical components within an internal combustion engine, serving the function of transmitting power from the piston to the crankshaft, thereby converting linear motion into rotational motion. This code applies to connecting rods that are not elsewhere specified within the broader 8409 chapter, and specifically when their intended application is the propulsion of marine vessels.

This category is distinguished from its sibling, 8409.99.92.90, which covers "Other" connecting rods. The differentiating factor is the explicit destination of the connecting rod for marine propulsion engines. Therefore, if a connecting rod is designed and manufactured for use in land-based vehicles, industrial machinery, or aircraft engines, it would likely fall under the broader "Other" category, unless another more specific subheading applies. The key criterion for classification under 8409.99.92.10 is the intended application within the marine propulsion system.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Classification decisions at this level will therefore rely on a precise determination of the connecting rod's intended use and its compatibility with engines of heading 8407 or 8408. Importers must be able to substantiate that the connecting rods are manufactured for, and are suitable for installation in, marine propulsion engines to correctly utilize this specific code.
