8466.93.30.00 - Of metalworking machine tools for cutting gears

This HTS category, 8466.93.30.00, specifically classifies parts and accessories made of metal which are designed for metalworking machine tools used in the process of cutting gears. This includes components such as castings, weldments, or fabrications that form the structural backbone of gear-cutting machinery. Examples include beds, bases, tables, heads, tails, saddles, cradles, cross slides, columns, arms, saw arms, wheelheads, tailstocks, headstocks, rams, frames, work-arbor supports, and C-frames that are integral to the operation of these specialized machines.

While other categories at the 8466.93 level might cover general-purpose parts for a broader range of metalworking machines, this specific code is precisely for those components dedicated to the intricate task of gear cutting. The emphasis is on the function of the machinery and the material of the part itself, distinguishing it from accessories for other types of machining operations. It's important to note that this classification applies to the raw structural components and not to fully assembled machines or tools themselves.

As this is a leaf node within the HTS structure, there are no further subdivisions. Classification is determined by the specific item being a metal part, forming a structural element, and being intended for a machine tool specifically designed for cutting gears. The material (metal) and the machine's primary function (gear cutting) are the key determinative factors for items falling under this code.
