8429.11.00.90 - Used or rebuilt

This HTS category, 8429.11.00.90, specifically classifies used or rebuilt track-laying bulldozers and angledozers. These are self-propelled construction machines designed for pushing large quantities of material such as soil, sand, or rubble. The "used or rebuilt" designation is critical, indicating that these machines have undergone prior use and may have been refurbished or repaired to a functional state.

This category is distinguished from its sibling, 8429.11.00.10, which covers new track-laying bulldozers and angledozers. The primary differentiating factor is the condition of the machine; this category applies only to those that are not in new condition. The emphasis is on the prior operational history and potential restoration of the equipment, rather than its original manufacturing date and condition.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification under 8429.11.00.90 is final for any track-laying bulldozer or bulldozer that meets the criteria of being used or rebuilt and falls within the scope of Chapter 84. The classification relies solely on the machine type (bulldozer/bulldozer), its propulsion system (track-laying), and its condition (used or rebuilt).
