8409.99.10.60 - For marine propulsion engines

This HTS classification specifically covers cast-iron parts intended for use with engines of heading 8407 or 8408. Crucially, these parts are limited to those that have undergone only basic finishing processes. This includes cleaning and machining solely for the removal of extraneous material such as fins, gates, sprues, and risers, or for the creation of locating points necessary for subsequent finishing operations. The intent is to capture raw or minimally processed cast-iron components that are destined for further manufacturing into engine parts.

It is important to distinguish this category from its siblings. Unlike 8409.99.10.40, which is designated for parts for specific vehicles, or the broader "Other" category 8409.99.10.80, this classification is narrowly defined by the material (cast-iron) and the limited nature of the processing. Parts that have undergone more extensive machining, fabrication, or assembly beyond the stipulated finishing would not fall under this heading and would require reclassification.

As this is a leaf node, there are no further subcategories. Therefore, classification within 8409.99.10.60 hinges on the precise physical state and the extent of processing applied to the cast-iron component, ensuring it meets the criteria of being "not advanced beyond cleaning, and machined only for the removal of fins, gates, sprues and risers or to permit location in finishing machinery."
