Overview

This HTS classification, 9902.15.47, is specifically designated for pistons intended for use solely or principally in marine propulsion engines. These pistons are characterized by a composite construction, featuring a cast steel crown and an aluminum body. A key defining criterion for inclusion in this category is a substantial weight of 12 kilograms or more. This classification effectively isolates these specialized, heavy-duty marine pistons from other types of pistons or engine components that might be classified elsewhere in the Harmonized Tariff Schedule.

As a leaf node within Chapter 99, this category does not have further subdivisions. Its purpose is to provide a distinct and temporary tariff treatment for these particular types of pistons, as indicated by their inclusion in Chapter 99, which pertains to temporary legislation and modifications. The specific reference to subheading 8409.99.92 in the description signifies that these pistons are being further categorized and potentially subject to specific trade agreement provisions or import restrictions.
