8429.51.10.55 - 11.4 m3 and over

This HTS classification, 8429.51.10.55, specifically designates new, integral tractor shovel loaders with a rear engine mounting and four-wheel drive, characterized by a substantial bucket capacity of 11.4 cubic meters and over. These machines are designed for heavy-duty material handling operations, particularly in construction, mining, and large-scale earthmoving projects, where their robust build and significant load capacity are essential.

The defining characteristic that distinguishes this category from its siblings is the precise volumetric capacity of the bucket. Categories like 8429.51.10.15, 8429.51.10.25, and others up to 8429.51.10.40 represent loaders with progressively smaller bucket sizes. Therefore, the key differentiator here is a bucket volume meeting or exceeding 11.4 cubic meters, indicating a class of loaders intended for the most demanding material transport requirements.

As this classification represents a leaf node within the HTS database, there are no further subcategories to introduce. The specificity of "11.4 m3 and over" serves as the final classification criterion for these particular types of front-end shovel loaders, ensuring that only the largest integral tractor shovel loaders fall within this designated code. Classification for these machines relies solely on their described configuration and bucket capacity.
