8466.93.15 - Cast-iron parts not advanced beyond cleaning, and machined only for the removal of fins, gates, sprues and risers or to permit location in finishing machinery
Sub-classifications
Overview
This HTS category, 8466.93.15, specifically covers cast-iron parts that have undergone minimal processing. These parts are typically designed as foundational components for machinery within headings 8456 to 8465. The key characteristic for classification here is that the cast-iron has been cleaned and then machined *only* to remove casting artifacts such as fins, gates, sprues, and risers, or to prepare the part for its integration into finishing machinery. Advanced machining operations or further processing beyond these basic modifications would typically move the item to a different classification.
The distinction for this category lies in the limited nature of the processing applied to the cast-iron. Unlike more advanced machined parts, these items retain their fundamental cast-iron form with only the most basic finishing steps. This ensures that the goods are still considered primarily cast-iron components and not fully fabricated or machined assemblies.
This category serves as a parent to more granular classifications that further refine the scope based on the specific type of metalworking machine tool for which these cast-iron parts are intended. The subcategories allow for specific identification of parts destined for machines used in precision gear cutting, grinding, or finishing operations, as well as a general "other" category for parts intended for a broader range of metalworking machinery.
