8483.90.80.10 - Parts of articles of subheading 8483.60.80

This HTS classification, 8483.90.80.10, specifically designates parts of articles falling under subheading 8483.60.80. This means it covers components or pieces that are integral to the operation of clutches and shaft couplings, excluding universal joints. These parts are essential for the transmission of rotational motion between shafts, ensuring that power can be effectively transferred in various mechanical systems.

Unlike its sibling category 8483.90.80.40, which is exclusively for parts of universal joints, this classification is broader, encompassing all other types of clutch and shaft coupling components not otherwise specified. It also differs from 8483.90.80.80, which serves as a residual category for any other parts not explicitly defined. Therefore, 8483.90.80.10 applies to specific elements such as friction plates, pressure plates, springs, diaphragms, hub components, or retainer rings that are designed for use in clutches and shaft couplings, but not for universal joints.

As this classification is a leaf node, it does not have further subcategories. Classification within 8483.90.80.10 relies on identifying that a part is indeed for a clutch or shaft coupling and is not a universal joint part. The specific function and design of the part, as well as its intended use in transmitting torque and accommodating misalignment or axial movement (in the case of couplings), are key determining factors.
