HS Code for Camshaft

The classification of a camshaft under HS code 8483.10 is determined by its primary function as a transmission shaft. Within the Harmonized System, Chapter 84 covers nuclear reactors, boilers, machinery, and mechanical appliances. Specifically, heading 8483 is reserved for transmission shafts (including cam shafts and crank shafts) and cranks; bearing housings and plain shaft bearings; gears and gearing; ball or roller screws; gear boxes and other speed changers, including torque converters; flywheels and pulleys, including pulley blocks; clutches and shaft couplings. The camshaft is a critical mechanical component in internal combustion engines, responsible for controlling the timing and operation of the intake and exhaust valves. Because it transforms rotational motion into linear motion to actuate valves, it is technically defined as a transmission shaft. The General Rules for the Interpretation (GRI) of the Harmonized System dictate that specific descriptions take precedence over general ones. While a camshaft is a part of an engine, heading 8483 provides a more specific description than the general parts of engines found in heading 8409. This specificity ensures that transmission components are grouped together regardless of the specific machine they are installed in, whether it be an automobile, a marine vessel, or industrial power generation equipment. The material composition, typically forged steel or cast iron, does not change this classification as the functional utility as a shaft is the primary determinant.

Common Misclassification

Camshafts are frequently misclassified under HS code 8409.91 or 8409.99, which cover parts suitable for use solely or principally with internal combustion piston engines. While a camshaft is indeed an engine part, the Harmonized System Explanatory Notes for heading 8483 explicitly include camshafts by name, making 8483.10 the legally correct and more specific classification. Another common error is using 7326.90 for other articles of iron or steel, which is a basket category that should only be used if no more specific heading exists in the nomenclature.

FAQ

What is the HS code for Camshaft?

The HS code for a camshaft is 8483.10, which falls under the category of transmission shafts and cranks.

Does the HS code change if the camshaft is for a motorcycle?

No, the classification remains 8483.10 as the heading covers transmission shafts for all types of machinery and engines, regardless of the vehicle type.
