9029.20.40.40 - For use in civil aircraft

This HTS category, 9029.20.40.40, specifically covers speedometers and tachometers that are designed and intended for use in civil aircraft. These instruments are crucial for monitoring and displaying the speed and engine rotational speed of aircraft. Their design and calibration will be specifically tailored to the demanding and precise requirements of aviation, distinguishing them from general-purpose automotive or industrial units.

This classification is a sub-category of "Other speedometers and tachometers" (9029.20.40) and is distinct from its sibling, 9029.20.40.80, which encompasses all other speedometers and tachometers not specifically designated for civil aircraft use. The key differentiating factor for this category is its explicit application within the civil aviation sector, which often dictates unique specifications and certifications.

As this is a leaf node, there are no further subcategories. Classification within 9029.20.40.40 relies on the explicit statement of intended use for civil aircraft. Importers should be prepared to provide documentation or evidence to support this designation, such as manufacturer specifications, certifications, or purchase orders clearly indicating the aircraft application.
