9902.16.40 - Used generators (alternators) of a kind used in conjunction with spark ignition or compression ignition internal combustion engines (provided for in subheading 8511.50.00)

This HTS classification, 9902.16.40, specifically addresses used generators, also known as alternators. These are electrical machines designed to produce alternating current. The critical defining characteristic for this classification is their intended application: they must be of a kind used in conjunction with spark ignition or compression ignition internal combustion engines, such as those found in automobiles, motorcycles, or power generators. This classification is a temporary provision, designed to manage specific trade situations under Chapter 99 of the Harmonized Tariff Schedule.

Given that this is a leaf node within the HTS structure, there are no further subcategories to introduce. The primary distinction for goods falling under 9902.16.40 lies in their condition (used) and their specific function of powering internal combustion engines, as opposed to new generators or generators designed for entirely different applications which would be classified elsewhere in the HTS. The underlying provision for new goods of this nature is found in subheading 8511.50.00, highlighting that 9902.16.40 acts as a specialized, temporary classification for the used counterpart.
