9029.90 - Parts and accessories:

Heading 9029.90 encompasses parts and accessories for a range of mechanical and electromechanical devices primarily used for measuring or counting. This category specifically includes components for revolution counters, production counters, taximeters, odometers, pedometers, speedometers, tachometers, and stroboscopes. These parts are essential for the functioning, repair, or enhancement of the instruments classified under the broader heading 9029.

Distinguishing this category from its siblings, 9029.10 and 9029.20, is crucial. While 9029.10 covers the complete assembled revolution counters, production counters, taximeters, odometers, and pedometers, and 9029.20 covers the complete assembled speedometers, tachometers, and stroboscopes, 9029.90 is exclusively for the individual components and accessories of these devices. For instance, a complete odometer would fall under 9029.10, but a replacement odometer cable or sensor would be classified here.

The subcategories within 9029.90 provide a further breakdown based on the specific type of instrument the part or accessory is intended for. For example, specific provisions exist for parts of taximeters (9029.90.20.00), bicycle speedometers (9029.90.40.00), and stroboscopes (9029.90.60.00). The residual category, 9029.90.80, is for parts and accessories that do not fit into these more specific subheadings, serving as a general catch-all for the remaining components within the scope of heading 9029.
