HS Code for Shaft coupling

Shaft couplings are classified under HS code 8483.60, a category dedicated to clutches and shaft couplings, including universal joints. This classification is based on the product's function as a mechanical linkage used to transmit rotational power between two shafts while accommodating various degrees of misalignment or end movement. Heading 8483 encompasses a broad range of transmission components, and subheading 8483.60 specifically captures the devices that connect shafts together. The classification remains consistent whether the coupling is rigid, flexible, or utilizes fluid or magnetic forces to transmit torque. Because these components are essential parts of mechanical power transmission systems, they are grouped with other transmission elements like gears and pulleys, rather than being classified by their constituent material (such as steel or aluminum) under Section XV.

Products Included

• Flexible couplings (e.g., jaw, sleeve, or tire couplings)
• Rigid couplings (e.g., sleeve or flange couplings)
• Universal joints (Cardan joints) for automotive or industrial use
• Fluid couplings and torque converters
• Magnetic couplings used for hermetic sealing
• Gear couplings and chain couplings

Common Misclassification

Shaft couplings are often confused with transmission shafts themselves, which fall under 8483.10. While the coupling connects the shafts, it is a distinct mechanical assembly. Another common misclassification occurs with 8483.40, which covers gears and gearing. While some couplings use gear-like teeth (gear couplings), they are classified under 8483.60 because their primary purpose is shaft connection rather than speed or torque conversion. Additionally, simple collars or fasteners might be misclassified as general hardware in Chapter 73, but if they function as a coupling, 8483.60 is the correct designation.

FAQ

What is the HS code for shaft coupling?

The HS code for a shaft coupling is 8483.60, which includes clutches and universal joints.

Are universal joints classified differently than standard couplings?

No, universal joints are specifically mentioned in the description for HS code 8483.60 and are classified alongside other shaft couplings.
