9014.10.10.00 - Optical instruments

This HTS classification, 9014.10.10.00, specifically covers direction-finding compasses. These instruments are designed to determine geographic direction, typically by aligning with the Earth's magnetic field. Examples include magnetic compasses used for navigation on land, sea, and in the air, as well as more advanced gyroscopic compasses that provide a stable directional reference independent of magnetic influences. The primary function is to aid in navigation and orientation, providing a crucial element for accurate positioning.

Within the broader category of "Direction finding compasses; other navigational instruments and appliances; parts and accessories thereof," this subcategory is distinguished by its focus solely on instruments whose primary purpose is direction finding. Sibling categories at this level would encompass other types of navigational equipment that do not primarily serve to determine direction, such as sextants, chronometers, or charting instruments, as well as parts and accessories for the entire range of navigational devices.

As this node is a leaf category, there are no further subcategories to introduce. Therefore, the classification of goods under 9014.10.10.00 hinges on the definitive characteristic of being a direction-finding compass. This means that any instrument whose core function is to indicate cardinal directions, regardless of its specific design (e.g., liquid-damped, dry-card, gyrocompass), will fall under this tariff code.
