8429.40.00.60 - Used or rebuilt

This HTS category, 8429.40.00.60, specifically covers used or rebuilt tamping machines and road rollers. These are self-propelled machines designed for soil compaction, asphalt paving, and other road construction or maintenance tasks. They are distinguished by their functional state, indicating they are not new units.

The primary sibling category to consider is "New" units under the same heading. This classification is exclusively for machinery that has been previously owned, operated, or rebuilt, as opposed to brand-new equipment. The "Used or rebuilt" designation is crucial for determining applicable duties and trade regulations.

As this is a leaf node, there are no further subcategories within this specific HTS code. Classification at this level relies on confirming the machinery's identity as a tamping machine or road roller and verifying its status as used or rebuilt. This ensures accurate tariff application based on the machine's condition and type.
