9902.16.01 - Used fixed ratio speed changers (provided for in subheading 8483.40.50), other than transmissions for the vehicles of headings 8701, 8702, 8703, 8704, and 8705

This HTS classification, 9902.16.01, designates specific used fixed ratio speed changers that are not intended for use in vehicles falling under headings 8701 through 8705. These speed changers are otherwise classifiable under subheading 8483.40.50. The core function of these items is to alter rotational speed through a non-variable gear ratio, and their exclusion from vehicular transmissions is a key distinguishing factor.

This temporary provision operates within Chapter 99 of the Harmonized Tariff Schedule, which encompasses temporary legislation and modifications. Therefore, goods classified here are subject to specific, potentially time-limited, import conditions or restrictions that may differ from the standard classification under Chapter 84. Unlike the broad categories of live animals or other general merchandise at the root level, this code targets a very specific type of mechanical component based on its function, condition (used), and end-use.

As this is a leaf node, there are no further subcategories under 9902.16.01. Classification under this code relies on the precise adherence to the description, confirming that the speed changer is indeed used, has a fixed ratio, and is not a transmission for the specified vehicle types. Importers must verify that the item meets all criteria to ensure correct customs declaration and compliance.
