8704.10.50.40 - With a capacity exceeding 63.5 metric tons but not exceeding 90.7 metric tons

This HTS classification, 8704.10.50.40, specifically covers rear-dump vehicles designed for off-highway use that possess a significant carrying capacity, defined as exceeding 63.5 metric tons but not exceeding 90.7 metric tons. These are heavy-duty haulers engineered for robust construction, mining, and other demanding industrial environments where precise weight management is crucial for operational efficiency and load distribution. Their primary function is the transportation of bulk materials over rough terrain, and their large capacity necessitates specialized design and engineering.

This category is differentiated from its siblings based on precise weight capacity thresholds. For instance, 8704.10.50.20 and 8704.10.50.30 cover vehicles with lesser capacities, while 8704.10.50.50 encompasses those exceeding the upper limit of this specific classification. The distinction lies solely in the rated payload capacity, a critical factor for determining the appropriate tariff and for understanding the intended operational scale of these specialized vehicles.

As this is a leaf node within the HTS, there are no further subcategories. Therefore, the classification is complete at this level, focusing on the definitive characteristic of rear-dump off-highway vehicles within the specified metric ton capacity range. Importers and exporters should ensure their declarations accurately reflect this capacity to ensure correct tariff application.
