8483.60.40 - Clutches and universal joints

HTS code 8483.60.40 encompasses clutches and universal joints, critical mechanical components used to transmit rotational motion between shafts. Clutches are designed to engage and disengage the flow of power, allowing for controlled starting, stopping, and speed adjustments in machinery. Universal joints, on the other hand, are coupling devices that transmit rotational power between shafts that are not in alignment, accommodating angular and axial misalignment. These items are generally found in various applications, from automotive and industrial machinery to agricultural equipment.

This specific classification is distinct from its sibling category, 8483.60.80.00, which covers "Other" clutches and universal joints. While 8483.60.40 is more granular, it is not a leaf node and further differentiates these components into more specific subcategories.

The subcategories under 8483.60.40 provide a more precise classification based on the specific type of coupling. HTS code 8483.60.40.40 is dedicated to "Clutches," focusing on devices primarily for engaging and disengaging power. Conversely, HTS code 8483.60.40.80 is assigned to "Universal joints," which are specifically designed to transmit torque through a changing angle between connected shafts. This subdivision allows for more accurate data collection and tariff application based on the distinct functional characteristics of each item.
