8431.49.10.10 - Of machinery of subheadings 8426.11, 8426.19 and 8426.30

This HTS category, 8431.49.10.10, encompasses parts and accessories specifically designed for machinery classified under subheadings 8426.11, 8426.19, and 8426.30. These subheadings generally cover various types of lifting and loading machinery, including ship's derricks, gantry cranes, and overhead travelling cranes. Therefore, this classification is relevant for components such as gears, shafts, bearings, hydraulic pumps, electrical control units, or structural elements that are exclusively or primarily intended for use with these specific types of cranes and lifting equipment.

It is important to distinguish this category from its siblings. HTS code 8431.49.10.60 covers parts for mobile lifting frames, straddle carriers, and works trucks fitted with a crane, which are distinct from the fixed or overhead crane types encompassed by this classification. The residual category, 8431.49.10.90, is for all other parts not specifically enumerated within the preceding sub-classifications of 8431.49.10.

As this HTS code represents a leaf node, there are no further subcategories. Classification into 8431.49.10.10 requires a direct link to the specific machinery types outlined in subheadings 8426.11, 8426.19, and 8426.30. The critical determinative factor is whether the part's design and intended use are exclusively or principally for these particular crane and lifting machines.
