8431.42.00.00 - Bulldozer or angledozer blades

This HTS category, 8431.42.00.00, specifically covers bulldozer or angledozer blades. These are the primary earth-moving attachments designed to be fitted to bulldozers or angledozer machinery for the purpose of pushing, leveling, or moving soil, sand, or other loose material. The blades are characterized by their large, typically flat or angled, metal construction, often with a cutting edge, and are engineered for heavy-duty excavation and grading tasks.

It is important to distinguish these bulldozer and angledozer blades from their sibling categories. For instance, category 8431.41.00 encompasses buckets, shovels, grabs, and grips, which are designed for different forms of material handling and excavation, such as scooping or grasping. Category 8431.43 relates to parts for boring or sinking machinery, clearly differentiating it by its specific application in drilling operations. Category 8431.49, designated as "Other," serves as a residual category for parts of machinery of headings 8426, 8429, or 8430 that do not fall into the more specific subheadings like 8431.42.

As 8431.42.00.00 is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification under this heading is definitive for bulldozer and angledozer blades. Classification relies on the clear identification of the part as a blade specifically designed and intended for mounting on and use with bulldozers or angledozer machinery for earthmoving operations.
