Overview
HTS Code 8458 encompasses lathes, including turning centers, specifically designed for the removal of metal. These machines utilize a cutting tool to remove material from a rotating workpiece, shaping it into the desired form. This category is distinct from other machinery classified in Section XVI by its specific function of metal removal through turning operations. Unlike grinding machines or milling machines (which also remove metal), lathes are characterized by the rotation of the workpiece against a stationary or traversing cutting tool.
Within HTS Code 8458, further subdivisions exist to distinguish between different types of lathes. The primary distinction is made between horizontal lathes, where the workpiece axis is horizontal, and other lathes which may include vertical lathes or specialized turning centers. This subcategorization is crucial for accurate classification, as the orientation and specific capabilities of the lathe can influence its application and subsequent import duties.
This classification is part of Chapter 84, which broadly covers nuclear reactors, boilers, and machinery and mechanical appliances. Within this chapter, 8458 focuses on a very specific type of machine tool. It is important to differentiate these metal-removing lathes from other machinery that might involve rotation but not necessarily for material subtraction, such as certain types of testing equipment or assembling machinery.
