8458.11.00.50 - With a power rating of 18.65 kW or greater but not exceeding 37.3 kW

This HTS classification covers numerically controlled horizontal lathes specifically designed for metalworking, falling within a defined power range. These machines are characterized by their ability to perform automated turning operations on metallic workpieces, guided by pre-programmed numerical instructions. The "horizontal" designation indicates that the workpiece rotates on a horizontal axis, and the "numerically controlled" aspect signifies advanced automation capabilities through computer-driven commands, distinguishing them from manually operated lathes.

This category is precisely delineated by its power rating. It explicitly includes horizontal, numerically controlled lathes that have a power output of 18.65 kW or greater, but do not exceed 37.3 kW. This differentiates it from the sibling category 8458.11.00.30, which covers machines with a power rating below 18.65 kW, and 8458.11.00.90, which encompasses machines with a power rating exceeding 37.3 kW. The exact kilowatt output is the critical factor for accurate classification at this level.

As a leaf node within the HTS structure, this classification represents a specific and definitive grouping of goods. There are no further subcategories under this code. Therefore, all numerically controlled horizontal lathes for metal removal falling within the specified power range of 18.65 kW to 37.3 kW will be classified here. Importers and exporters should ensure the machine's nameplate or technical specifications clearly indicate its power rating to confirm correct classification.
