8466.93.15.30 - For metalworking machine tools for cutting, grinding or finishing gears

This HTS category specifically covers cast-iron parts of metalworking machine tools that have undergone minimal processing. The parts classified here are limited to those that have been cleaned and machined only to remove fins, gates, sprues, and risers, or to prepare them for further finishing operations. Examples include rough castings of beds, bases, tables, heads, saddles, columns, arms, and frames, provided they meet the described level of finishing.

The distinction between this category and its sibling, 8466.93.15.60 "Other," lies in the material and processing. While sibling categories might encompass fabricated parts or those made from different materials, this subcategory is strictly for cast-iron components in their initial stages of manufacturing. The limited machining described is crucial; any more extensive machining or assembly would generally lead to classification under a different, more finished category.

As this HTS code represents a leaf node, there are no further subcategories. The classification is complete once the part meets the criteria of being a cast-iron component of a specified machine tool part, having been cleaned and minimally machined for preparation. Understanding the precise definition of "machined only for the removal of fins, gates, sprues and risers or to permit location in finishing machinery" is paramount for accurate classification within this specific entry.
