Radio-based Positioning as principal function determines classification under radio navigational aids, not data-transmission apparatus.

Device principal function is radio-based determination and tracking of geographic position; classification follows the General Rules of Interpretation and Note 3 to Section XVI applying the principal-function/essential-character test. GPS receiver and satellite positioning impart the essential character, while modem and sensors are ancillary supporting components. Consequently the composite product is classifiable as a radio navigational aid apparatus and placed under tariff heading 8526, specifically tariff item 8526 91 90 as other radio navigational aid apparatus.

Issues: Whether the imported "Alesea Reel Tracking Device" is classifiable under Heading 8526 (radio navigational aid apparatus) or under Heading 8517 (apparatus for transmission/reception of data) or any other heading, having regard to its composite components and principal function.

Analysis: The Authority applied the General Rules of Interpretation and Note 3 to Section XVI to determine classification of a composite device by its principal function or component imparting essential character. The device incorporates GPS receiver, gyroscope, accelerometer, digital compass, internal thermometer and a modem. Examination of the product literature and technical architecture showed that the device's commercial identity and primary purpose are location tracking, geo-fencing and proof-of-delivery, functions that depend fundamentally on satellite radio-based determination of geographic position. The modem and sensors were found to be ancillary or supportive: transmission and supporting metrics facilitate but do not define the device's essential character. International administrative rulings and settled judicial principles concerning essential character and dominant use were applied to conclude which component imparts the principal function.

Conclusion: The principal function of the "Alesea Reel Tracking Device" is radio-based determination and tracking of geographic position; the device is classifiable under Tariff Heading 8526, specifically under tariff item 8526 91 90 as other radio navigational aid apparatus.
