8458.11.00 - Numerically controlled

HTS Code 8458.11.00 specifically classifies horizontal lathes that are numerically controlled. These machines are designed for turning operations, which involve removing material to shape metal workpieces. The defining characteristic of this classification is the integration of numerical control (NC) or computer numerical control (CNC) systems, which automate the machine's movements and operations based on programmed instructions. This allows for high precision, repeatability, and the production of complex shapes that would be difficult or impossible to achieve with manual controls.

This category is distinguished from its sibling, HTS 8458.19.00 ("Other"), by the presence of numerical control. While both fall under horizontal lathes, 8458.19.00 would encompass horizontal lathes that lack this automated control, relying instead on manual or simpler mechanical adjustments. The key differentiator is the level of automation and the technology used to guide the machining process.

Within HTS 8458.11.00, further subdivisions exist. The subcategory 8458.11.00.05 specifically addresses lathes that are used or rebuilt, indicating that their condition and previous operational history are considered for classification. The remaining subcategory, denoted as "Other," would encompass new or demonstrably un-used numerically controlled horizontal lathes, allowing for a clear distinction based on the product's status.
