HS Code for Universal joint

Universal joints are classified under HS code 8483.60, which encompasses clutches and shaft couplings, including universal joints. This classification is based on the mechanical function of the component as a power transmission element designed to connect two shafts whose axes are inclined at an angle to each other. Under the Harmonized System, Chapter 84 includes nuclear reactors, boilers, machinery, and mechanical appliances. Heading 8483 specifically addresses transmission shafts, cranks, bearing housings, and other internal mechanical components. Universal joints, often referred to as Cardan joints, Hooke's joints, or U-joints, consist of a cross-shaped element (the spider) and two yokes. Their primary role is to allow the transmission of torque while accommodating angular misalignment. A frequent point of confusion in customs classification is whether a universal joint intended for a specific vehicle should be classified as a vehicle part under Chapter 87. However, Note 2(e) to Section XVII of the HS Nomenclature explicitly excludes "articles of heading 8483" from being classified as parts of vehicles, aircraft, or vessels. This means that even if a universal joint is specifically engineered for a heavy-duty truck or an agricultural tractor, it must be classified under 8483.60 rather than 8708 or 8433. This rule ensures consistency across different industries. The classification process involves verifying that the item is indeed a coupling device and not a simple joint or fastener. Technical documentation should highlight the torque capacity and the mechanical design to distinguish it from other types of couplings like flexible couplings or fluid couplings, which also fall under 8483.60 but represent different engineering solutions.

Products Included

• Cardan joints (U-joints)
• Hooke's joints
• Constant velocity (CV) joints (when classified as couplings)
• Shaft couplings for industrial machinery
• Automotive universal joints

Common Misclassification

The most common misclassification is under 8708.99 (parts for motor vehicles). While these joints are used in cars, Section XVII Note 2(e) mandates they stay in 8483.60. They are also sometimes confused with 7318 (screws, bolts, and similar articles) if they are small or simple in design.

FAQ

What is the HS code for a universal joint?

The HS code for a universal joint is 8483.60, as it is categorized under clutches and shaft couplings.

Does the material of the joint change the HS code?

Generally, no. Whether made of steel, alloy, or other metals, if it functions as a shaft coupling, it remains under 8483.60.
